1 D-Bus 1.9.8 (UNRELEASED)
6 • full test coverage now requires GLib 2.36
7 • full test coverage now requires PyGI (PyGObject 3,
8 "import gi.repository.GObject") instead of the
9 obsolete PyGObject 2 ("import gobject")
13 • add GLib-style "installed tests" (fd.o #88810, Simon McVittie)
15 • better regression test coverage, including systemd activation
16 (fd.o #57952, #88810; Simon McVittie)
20 • fatal errors correctly make the dbus-daemon exit even if <syslog/> is
21 turned off (fd.o #88808, Simon McVittie)
23 • TCP sockets on Windows no longer fail to listen approximately 1 time
24 in 256, caused by a logic error that should have always made it fail but
25 was mitigated by incorrect endianness for the port number
26 (fd.o #87999, Ralf Habacker)
28 • fix some Windows build failures (fd.o #88009, #88010; Ralf Habacker)
30 • on Windows, allow up to 8K connections to the dbus-daemon instead of the
31 previous 64, completing a previous fix which only worked under
32 Autotools (fd.o #71297, Ralf Habacker)
34 • on Windows, if the IP family is unspecified only use IPv4,
35 to mitigate IPv6 not working correctly (fd.o #87999, Ralf Habacker)
37 • fix some unlikely memory leaks on OOM (fd.o #88087, Simon McVittie)
39 • lcov code coverage analysis works again (fd.o #88808, Simon McVittie)
41 • fix an unused function error with --disable-embedded-tests (fd.o #87837,
44 D-Bus 1.9.6 (2015-01-05)
47 The “I do have a bread knife” release.
51 • Do not allow calls to UpdateActivationEnvironment from uids other than
52 the uid of the dbus-daemon. If a system service installs unsafe
53 security policy rules that allow arbitrary method calls
54 (such as CVE-2014-8148) then this prevents memory consumption and
55 possible privilege escalation via UpdateActivationEnvironment.
57 We believe that in practice, privilege escalation here is avoided
58 by dbus-daemon-launch-helper sanitizing its environment; but
59 it seems better to be safe.
61 • Do not allow calls to UpdateActivationEnvironment or the Stats interface
62 on object paths other than /org/freedesktop/DBus. Some system services
63 install unsafe security policy rules that allow arbitrary method calls
64 to any destination, method and interface with a specified object path;
65 while less bad than allowing arbitrary method calls, these security
66 policies are still harmful, since dbus-daemon normally offers the
67 same API on all object paths and other system services might behave
72 • Add missing initialization so GetExtendedTcpTable doesn't crash on
73 Windows Vista SP0 (fd.o #77008, Илья А. Ткаченко)
75 D-Bus 1.9.4 (2014-11-24)
78 The “extra-sturdy caramel” release.
82 • Partially revert the CVE-2014-3639 patch by increasing the default
83 authentication timeout on the system bus from 5 seconds back to 30
84 seconds, since this has been reported to cause boot regressions for
85 some users, mostly with parallel boot (systemd) on slower hardware.
87 On fast systems where local users are considered particularly hostile,
88 administrators can return to the 5 second timeout (or any other value
89 in milliseconds) by saving this as /etc/dbus-1/system-local.conf:
92 <limit name="auth_timeout">5000</limit>
95 (fd.o #86431, Simon McVittie)
97 • Add a message in syslog/the Journal when the auth_timeout is exceeded
98 (fd.o #86431, Simon McVittie)
100 • Send back an AccessDenied error if the addressed recipient is not allowed
101 to receive a message (and in builds with assertions enabled, don't
102 assert under the same conditions). (fd.o #86194, Jacek Bukarewicz)
104 D-Bus 1.9.2 (2014-11-10)
107 The “structurally unsound flapjack” release.
111 • Increase dbus-daemon's RLIMIT_NOFILE rlimit to 65536
112 so that CVE-2014-3636 part A cannot exhaust the system bus'
113 file descriptors, completing the incomplete fix in 1.8.8.
114 (CVE-2014-7824, fd.o #85105; Simon McVittie, Alban Crequy)
118 • D-Bus Specification version 0.25
119 · new value 'const' for EmitsChangedSignal annotation
120 (fd.o #72958, Lennart Poettering)
121 · new ALLOW_INTERACTIVE_AUTHORIZATION flag, for PolicyKit and similar
122 (fd.o #83449; Lennart Poettering, Simon McVittie)
123 · annotate table of types with reserved/basic/container, and for
124 basic types, fixed/string-like
125 · clarify arbitrary limits by quoting them in mebibytes
127 • New API: add accessors for the ALLOW_INTERACTIVE_AUTHORIZATION flag
128 (fd.o #83449, Simon McVittie)
130 • Add dbus-test-tool, a D-Bus swiss army knife with multiple subcommands,
131 useful for debugging and performance testing:
132 · dbus-test-tool spam: send repeated messages
133 · dbus-test-tool echo: send an empty reply for all method calls
134 · dbus-test-tool black-hole: do not reply to method calls
135 (fd.o #34140; Alban Crequy, Simon McVittie, Will Thompson)
137 • Add support for process ID in credentials-passing on NetBSD
138 (fd.o #69702, Patrick Welche)
140 • Add an example script to find potentially undesired match rules
141 (fd.o #84598, Alban Crequy)
143 • Document the central assumption that makes our use of credentials-passing
144 secure (fd.o #83499, Simon McVittie)
146 • Replace the dbus-glib section of the tutorial with a GDBus recommendation,
147 and add some links to GDBus and QtDBus documentation (fd.o #25140,
152 • Use a less confusing NoReply message when disconnected with a reply pending
153 (fd.o #76112, Simon McVittie)
155 • Make the .pc file relocatable by letting pkg-config do all variable
156 expansion itself (fd.o #75858, Руслан Ижбулатов)
158 • Fix a build failure on platforms with kqueue, which regressed in 1.9.0
159 (fd.o #85563, Patrick Welche)
161 • Consistently save errno after socket calls (fd.o #83625, Simon McVittie)
163 • In dbus-spawn, when the grandchild process exits due to a failed exec(),
164 do not lose the exec() errno (fd.o #24821, Simon McVittie)
166 • Do not fail the tests if a parent process has leaked non-close-on-exec
167 file descriptors to us (fd.o #73689, fd.o #83899; Simon McVittie)
169 • Do not fail the tests on Unix platforms with incomplete
170 credentials-passing support, but do fail if we can't pass credentials
171 on a platform where it is known to work: Linux, FreeBSD, OpenBSD, NetBSD
172 (fd.o #69702, Simon McVittie)
174 • Detect accept4, dirfd, inotify_init1, pipe2, and Unix fd passing
175 when building with cmake, and expand test coverage there
176 (fd.o #73689; Ralf Habacker, Simon McVittie)
178 D-Bus 1.9.0 (2014-10-01)
181 The “tiered cheeses” release.
185 • Support for the systemd: (LISTEN_FDS) pseudo-transport on Linux now
186 requires either the libsystemd or libsd-daemon shared library, dropping the
187 embedded convenience copy of sd-daemon (fd.o #71818, Simon)
189 Build-time configuration changes:
191 • The Stats interface is now enabled by default, and locked-down to
192 root-only on the system bus. Configure with --disable-stats
193 to disable it altogether on memory- or disk-constrained systems,
194 or see ${docdir}/examples/ to open it up to non-root users on the
195 system bus or restrict access on the session bus.
196 (fd.o #80759; Simon McVittie, Alban Crequy)
198 • The CMake build system now builds the same shared library name as Autotools
199 on at least Linux and Windows:
200 - on Linux (and perhaps other Unix platforms), it previously built
201 libdbus-1.so, but now builds libdbus-1.so.3.* with development
202 symlink libdbus-1.so and SONAME/symlink libdbus-1.so.3
203 - on Windows, it previously built either libdbus-1.dll (release) or
204 libdbus-1d.dll (debug), but now builds libdbus-1-3.dll, copied to
205 libdbus-1.dll for compatibility with older applications.
206 (fd.o #74117, Ralf Habacker)
210 • D-Bus Specification version 0.24
211 · document how to quote match rules (fd.o #24307, Simon McVittie)
212 · explicitly say that most message types never expect a reply
213 regardles of whether they have NO_REPLY_EXPECTED
214 (fd.o #75749, Simon McVittie)
216 • on Unix platforms, disable Nagle's algorithm on TCP connections to improve
217 initial latency (fd.o #75544, Matt Hoosier)
219 • use backtrace() if it is in -lexecinfo instead of libc, as on NetBSD
220 (fd.o #69702, Patrick Welche)
222 • in dbus-monitor, print more information about file descriptors
223 (fd.o #80603, Alban Crequy)
225 • do not install system bus configuration if built for Windows
226 (fd.o #83583; Ralf Habacker, Simon McVittie)
228 • Add GetAllMatchRules to the Stats interface (fd.o #24307, Alban Crequy)
230 • Add a regression test for file descriptor passing (fd.o #83622,
235 • fix an incorrect error message if a Unix socket path is too long
236 (fd.o #73887, Antoine Jacoutot)
238 • in an MSYS/Cygwin environment, pass Unix-style filenames to xmlto,
239 fixing documentation generation (fd.o #75860, Руслан Ижбулатов)
241 • in Unix with X11, avoid giving dbus-launch a misleading argv[0]
242 in ps(1) (fd.o #69716, Chengwei Yang)
244 • avoid calling poll() with timeout < -1, which is considered invalid
245 on FreeBSD and NetBSD (fd.o #78480, Jaap Boender)
247 • be portable to BSD-derived platforms where O_CLOEXEC is unavailable in libc
248 (like Mac OS X 10.6), or available in libc but unsupported by the kernel
249 (fd.o #77032; rmvsxop, OBATA Akio, Patrick Welche)
251 • Fix include path for test/internal/*.c with cmake (Ralf Habacker)
253 • Documentation improvements
254 (fd.o #80795, #84313; Thomas Haller, Sebastian Rasmussen)
256 • in dbus-monitor, do not leak file descriptors that we have monitored
257 (fd.o #80603, Alban Crequy)
259 • Set the close-on-exec flag for the inotify file descriptor, even
260 if built with CMake or older libc (fd.o #73689, Simon McVittie)
262 • Remove some LGPL code from the Windows dbus-daemon
263 (fd.o #57272, Ralf Habacker)
265 D-Bus 1.8.8 (2014-09-16)
268 The "smashy smashy egg man" release.
272 • Do not accept an extra fd in the padding of a cmsg message, which
273 could lead to a 4-byte heap buffer overrun.
274 (CVE-2014-3635, fd.o #83622; Simon McVittie)
276 • Reduce default for maximum Unix file descriptors passed per message
277 from 1024 to 16, preventing a uid with the default maximum number of
278 connections from exhausting the system bus' file descriptors under
279 Linux's default rlimit. Distributors or system administrators with a
280 more restrictive fd limit may wish to reduce these limits further.
282 Additionally, on Linux this prevents a second denial of service
283 in which the dbus-daemon can be made to exceed the maximum number
284 of fds per sendmsg() and disconnect the process that would have
286 (CVE-2014-3636, fd.o #82820; Alban Crequy)
288 • Disconnect connections that still have a fd pending unmarshalling after
289 a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
290 removing the possibility of creating an abusive connection that cannot be
291 disconnected by setting up a circular reference to a connection's
293 (CVE-2014-3637, fd.o #80559; Alban Crequy)
295 • Reduce default for maximum pending replies per connection from 8192 to 128,
296 mitigating an algorithmic complexity denial-of-service attack
297 (CVE-2014-3638, fd.o #81053; Alban Crequy)
299 • Reduce default for authentication timeout on the system bus from
300 30 seconds to 5 seconds, avoiding denial of service by using up
301 all unauthenticated connection slots; and when all unauthenticated
302 connection slots are used up, make new connection attempts block
303 instead of disconnecting them.
304 (CVE-2014-3639, fd.o #80919; Alban Crequy)
308 • Check for libsystemd from systemd >= 209, falling back to
309 the older separate libraries if not found (Umut Tezduyar Lindskog,
312 • On Linux, use prctl() to disable core dumps from a test executable
313 that deliberately raises SIGSEGV to test dbus-daemon's handling
314 of that condition (fd.o #83772, Simon McVittie)
316 • Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
319 • Improve documentation for running tests on Windows (fd.o #41252,
322 D-Bus 1.8.6 (2014-06-02)
327 • On Linux ≥ 2.6.37-rc4, if sendmsg() fails with ETOOMANYREFS, silently drop
328 the message. This prevents an attack in which a malicious client can
329 make dbus-daemon disconnect a system service, which is a local
331 (fd.o #80163, CVE-2014-3532; Alban Crequy)
333 • Track remaining Unix file descriptors correctly when more than one
334 message in quick succession contains fds. This prevents another attack
335 in which a malicious client can make dbus-daemon disconnect a system
337 (fd.o #79694, fd.o #80469, CVE-2014-3533; Alejandro Martínez Suárez,
338 Simon McVittie, Alban Crequy)
342 • When dbus-launch --exit-with-session starts a dbus-daemon but then cannot
343 attach to a session, kill the dbus-daemon as intended
344 (fd.o #74698, Роман Донченко)
346 D-Bus 1.8.4 (2014-06-10)
351 • Alban Crequy at Collabora Ltd. discovered and fixed a denial-of-service
352 flaw in dbus-daemon, part of the reference implementation of D-Bus.
353 Additionally, in highly unusual environments the same flaw could lead to
354 a side channel between processes that should not be able to communicate.
355 (CVE-2014-3477, fd.o #78979)
357 D-Bus 1.8.2 (2014-04-30)
360 The “nobody wants red” release.
364 • in the CMake build system, add some hints for Linux users cross-compiling
365 Windows D-Bus binaries to be able to run tests under Wine
366 (fd.o #41252, Ralf Habacker)
368 • add Documentation key to dbus.service (fd.o #77447, Cameron Norman)
372 • in "dbus-uuidgen --ensure", try to copy systemd's /etc/machine-id
373 to /var/lib/dbus/machine-id instead of generating an entirely new ID
374 (fd.o #77941, Simon McVittie)
376 • if dbus-launch receives an X error very quickly, do not kill
377 unrelated processes (fd.o #74698, Роман Донченко)
379 • on Windows, allow up to 8K connections to the dbus-daemon, instead of the
380 previous 64 (fd.o #71297; Cristian Onet, Ralf Habacker)
382 • cope with \r\n newlines in regression tests, since on Windows,
383 dbus-daemon.exe uses text mode (fd.o #75863, Руслан Ижбулатов)
385 D-Bus 1.8.0 (2014-01-20)
388 The “Wolverine distrusts my printer” release.
390 This starts a new stable branch. The 1.6.x branch is now considered to be
391 outdated, and will only receive fixes for serious bugs such as security
392 flaws. The 1.4.x and 1.2.x branches no longer have upstream support and
393 are unlikely to get any more releases, but if distributors still need to
394 support them, please share security patches via upstream.
396 Summary of changes since 1.6.x:
398 • libdbus always behaves as if dbus_threads_init_default() had been called
399 (thread-safety by default)
400 • new dbus-run-session tool, replacing certain misuses of dbus-launch
401 • dbus-monitor can talk to outdated versions of dbus-daemon again
402 • new org.freedesktop.DBus.GetConnectionCredentials method
403 • GetConnectionUnixProcessID also works correctly on Windows, returning
404 the Windows process ID
405 • GetConnectionWindowsSID returns the correct SID on Windows
406 • expat is required, libxml2 can no longer be used as a substitute
407 • the userDB cache is required, and cannot be disabled
408 • a 64-bit integer type (either int, long, long long or _int64) is required
409 • better systemd-journald integration on Linux
410 • fixed long-standing fd and array leaks when failing to parse a message
411 • fixed referenced-but-never-freed parent nodes (effectively memory leaks)
412 when using certain object-path allocation patterns, notably in Avahi
413 • better defaults for Windows support
414 • better CMake support
415 • better portability to mingw32, FreeBSD, NetBSD, QNX and Hurd
416 • the source language for the man pages is now Docbook XML
418 Enhancements since 1.7.10:
420 • Enhance the CMake build system to check for GLib and compile/run
421 a subset of the regression tests (fd.o #41252, #73495; Ralf Habacker)
425 • don't rely on va_copy(), use DBUS_VA_COPY() wrapper (fd.o #72840,
428 • fix compilation of systemd journal support on older systemd versions where
429 sd-journal.h doesn't include syslog.h (fd.o #73455, Ralf Habacker)
431 • fix compilation on older MSVC versions by including stdlib.h
432 (fd.o #73455, Ralf Habacker)
434 • Allow <allow_anonymous/> to appear in an included configuration file
435 (fd.o #73475, Matt Hoosier)
437 Test behaviour changes since 1.7.10:
439 • If the tests crash with an assertion failure, they no longer default to
440 blocking for a debugger to be attached. Set DBUS_BLOCK_ON_ABORT in the
441 environment if you want the old behaviour.
443 • To improve debuggability, the dbus-daemon and dbus-daemon-eavesdrop tests
444 can be run with an external dbus-daemon by setting
445 DBUS_TEST_DAEMON_ADDRESS in the environment. Test-cases that require
446 an unusually-configured dbus-daemon are skipped.
448 D-Bus 1.7.10 (2014-01-06)
451 The “weighted companion cube” release.
453 This is a release candidate for D-Bus 1.8.
455 D-Bus Specification 0.23:
457 • don't require messages with no INTERFACE to be dispatched
458 (fd.o #68597, Simon McVittie)
460 • document "tcp:bind=..." and "nonce-tcp:bind=..." (fd.o #72301,
463 • define "listenable" and "connectable" addresses, and discuss
464 the difference (fd.o #61303, Simon McVittie)
468 • support printing Unix file descriptors in dbus-send, dbus-monitor
469 (fd.o #70592, Robert Ancell)
471 • don't install systemd units if --disable-systemd is given
472 (fd.o #71818, Chengwei Yang)
476 • don't leak memory on out-of-memory while listing activatable or
477 active services (fd.o #71526, Radoslaw Pajak)
479 • fix undefined behaviour in a regression test (fd.o #69924, DreamNik)
481 • escape Unix socket addresses correctly (fd.o #46013, Chengwei Yang)
483 • on SELinux systems, don't assume that SECCLASS_DBUS, DBUS__ACQUIRE_SVC
484 and DBUS__SEND_MSG are numerically equal to their values in the
485 reference policy (fd.o #88719, osmond sun)
487 • define PROCESS_QUERY_LIMITED_INFORMATION if missing from MinGW < 4 headers
488 (fd.o #71366, Matt Fischer)
490 • define WIN32_LEAN_AND_MEAN to avoid conflicts between winsock.h and
491 winsock2.h (fd.o #71405, Matt Fischer)
493 • do not return failure from _dbus_read_nonce() with no error set,
494 preventing a potential crash (fd.o #72298, Chengwei Yang)
496 • on BSD systems, avoid some O(1)-per-process memory and fd leaks in kqueue,
497 preventing test failures (fd.o #69332, fd.o #72213; Chengwei Yang)
499 • fix warning spam on Hurd by not trying to set SO_REUSEADDR on Unix sockets,
500 which doesn't do anything anyway on at least Linux and FreeBSD
501 (fd.o #69492, Simon McVittie)
503 • fix use of TCP sockets on FreeBSD and Hurd by tolerating EINVAL from
504 sendmsg() with SCM_CREDS (retrying with plain send()), and looking
505 for credentials more correctly (fd.o #69492, Simon McVittie)
507 • ensure that tests run with a temporary XDG_RUNTIME_DIR to avoid
508 getting mixed up in XDG/systemd "user sessions" (fd.o #61301,
511 • refresh cached policy rules for existing connections when bus
512 configuration changes (fd.o #39463, Chengwei Yang)
514 D-Bus 1.7.8 (2013-11-01)
517 The “extreme hills” release.
521 • If systemd support is enabled, libsystemd-journal is now required.
525 • When activating a non-systemd service under systemd, annotate its
526 stdout/stderr with its bus name in the Journal. Known limitation:
527 because the socket is opened before forking, the process will still be
528 logged as if it had dbus-daemon's process ID and user ID.
529 (fd.o #68559, Chengwei Yang)
531 • Document more configuration elements in dbus-daemon(1)
532 (fd.o #69125, Chengwei Yang)
536 • Don't leak string arrays or fds if dbus_message_iter_get_args_valist()
537 unpacks them and then encounters an error (fd.o #21259, Chengwei Yang)
539 • If compiled with libaudit, retain CAP_AUDIT_WRITE so we can write
540 disallowed method calls to the audit log, fixing a regression in 1.7.6
541 (fd.o #49062, Colin Walters)
543 • path_namespace='/' in match rules incorrectly matched nothing; it
544 now matches everything. (fd.o #70799, Simon McVittie)
546 D-Bus 1.7.6 (2013-10-09)
549 The “CSI Shrewsbury” release.
551 Build-time configuration changes:
553 • Directory change notification via dnotify on Linux is no longer
554 supported; it hadn't compiled successfully since 2010 in any case.
555 If you don't have inotify (Linux) or kqueue (*BSD), you will need
556 to send SIGHUP to the dbus-daemon when its configuration changes.
557 (fd.o #33001, Chengwei Yang)
559 • Compiling with --disable-userdb-cache is no longer supported;
560 it didn't work since at least 2008, and would lead to an extremely
561 slow dbus-daemon even it worked. (fd.o #15589, #17133, #66947;
564 • The DBUS_DISABLE_ASSERTS CMake option didn't actually disable most
565 assertions. It has been renamed to DBUS_DISABLE_ASSERT to be consistent
566 with the Autotools build system. (fd.o #66142, Chengwei Yang)
568 • --with-valgrind=auto enables Valgrind instrumentation if and only if
569 valgrind headers are available. The default is still --with-valgrind=no.
570 (fd.o #56925, Simon McVittie)
574 • Platforms with no 64-bit integer type are no longer supported.
575 (fd.o #65429, Simon McVittie)
577 • GNU make is now (documented to be) required. (fd.o #48277, Simon McVittie)
579 • Full test coverage no longer requires dbus-glib, although the tests do not
580 exercise the shared library (only a static copy) if dbus-glib is missing.
581 (fd.o #68852, Simon McVittie)
585 • D-Bus Specification 0.22
586 · Document GetAdtAuditSessionData() and
587 GetConnectionSELinuxSecurityContext() (fd.o #54445, Simon)
588 · Fix example .service file (fd.o #66481, Chengwei Yang)
589 · Don't claim D-Bus is "low-latency" (lower than what?), just
590 give factual statements about it supporting async use
591 (fd.o #65141, Justin Lee)
592 · Document the contents of .service files, and the fact that
593 system services' filenames are constrained
594 (fd.o #66608; Simon McVittie, Chengwei Yang)
596 • Be thread-safe by default on all platforms, even if
597 dbus_threads_init_default() has not been called. For compatibility with
598 older libdbus, library users should continue to call
599 dbus_threads_init_default(): it is harmless to do so.
600 (fd.o #54972, Simon McVittie)
602 • Add GetConnectionCredentials() method (fd.o #54445, Simon)

607 • Add dbus-send --peer=ADDRESS (connect to a given peer-to-peer connection,
608 like --address=ADDRESS in previous versions) and dbus-send --bus=ADDRESS
609 (connect to a given bus, like dbus-monitor --address=ADDRESS).
610 dbus-send --address still exists for backwards compatibility,

638 an invalid pointer if the string is later freed (fd.o #65959, Chengwei Yang)
640 • If malloc() returns NULL in dbus_set_error(), don't va_end() a va_list
641 that was never va_start()ed (fd.o #66300, Chengwei Yang)

716 D-Bus 1.7.4 (2013-06-13)
719 The “but is your thread-safety thread-safe?” release.
723 • CVE-2013-2168: Fix misuse of va_list that could be used as a denial
724 of service for system services. Vulnerability reported by Alexandru Cornea.
729 • The Windows version of libdbus now contains a C++ source file, used
730 to provide global initialization when the library is loaded.
731 gcc (mingw*) users should ensure that g++ is also installed.
733 • The libxml2-based configuration reader (which hasn't worked for 2.5 years,
734 and was never the recommended option) has been removed. Expat is now a
739 • It should now be safe to call dbus_threads_init_default() from any thread,
740 at any time. Authors of loadable modules and plugins that use libdbus
741 should consider doing so during initialization.
742 (fd.o #54972, Simon McVittie)
744 • Improve dbus-send documentation and command-line parsing (fd.o #65424,
748 · dbus-run-session: experimental new tool to start a temporary D-Bus
749 session, e.g. for regression tests or a text console, replacing
750 certain uses of dbus-launch which weren't really correct
755 • In dbus-daemon, don't crash if a .service file starts with key=value
756 (fd.o #60853, Chengwei Yang)
759 · Fix a crash similar to CVE-2013-2168 the first time we try to use syslog
760 on a platform not defining LOG_PERROR, such as Solaris or QNX.
761 This regressed in 1.7.0. (Simon)
762 · Fix an assertion failure if we try to activate systemd services before
763 systemd connects to the bus (fd.o #50199, Chengwei Yang)
764 · Avoid compiler warnings for ignoring the return from write()
768 · Under cmake, install runtime libraries (DLLs) into bin/ instead of lib/
769 so that Windows finds them (fd.o #59733, Ralf Habacker)
771 D-Bus 1.7.2 (2013-04-25)
774 The “only partially opaque” release.
776 Configuration changes:
778 • On non-QNX Unix platforms, the default limit on fds per message in the
779 session bus configuration has reduced from 4096 to 1024. The default
780 limit used on the system bus was already 1024. On QNX, both limits are
781 reduced further, to 128.
785 • D-Bus Specification 0.21
786 · Following Unicode Corrigendum #9, the noncharacters U+nFFFE, U+nFFFF,
787 U+FDD0..U+FDEF are allowed in UTF-8 strings again. (fd.o #63072,
792 • Diagnose incorrect use of dbus_connection_get_data() with negative slot
793 (i.e. before allocating the slot) rather than returning junk
794 (fd.o #63127, Dan Williams)
796 • Fix a cmake build regression since 1.7.0 (fd.o #63682; Ralf Habacker,
800 · On Linux, link successfully with glibc 2.17 (fd.o #63166, Simon McVittie)
801 · Under systemd, log to syslog only, not stderr, avoiding duplication
802 (fd.o #61399, #39987; Colin Walters, Dagobert Michelsen)
803 · Under systemd, remove unnecessary dependency on syslog.socket
804 (fd.o #63531, Cristian Rodríguez)
805 · Include alloca.h for alloca() if available, fixing compilation on
806 Solaris 10 (fd.o #63071, Dagobert Michelsen)

810 meinproc's XSLT stylesheets (fd.o #61637, Ralf Habacker)
811 · Reduce the default limit on number of fds per message to 128 under
812 QNX, working around an arbitrary OS limit (fd.o #61176, Matt Fischer)
815 · Do not claim that all bus clients have the dbus-daemon's credentials;
816 pick up local TCPv4 clients' credentials (process ID and security
817 identifier, i.e. user) using GetExtendedTcpTable() (fd.o #61787,

823 The "Disingenuous Assertions" release.
825 This is a new development release, starting the 1.7.x branch. D-Bus 1.6
826 remains the recommended version for long-term-supported distributions
827 or the upcoming GNOME 3.8 release.
829 Build-time configuration changes:
831 • The --with-dbus-session-bus-default-address configure option is no longer
832 supported. Use the new --with-dbus-session-bus-connect-address and
833 --with-dbus-session-bus-listen-address options instead. On Windows, you
834 usually want them to have the same argument; on Unix, the defaults are
837 • Similarly, the DBUS_SESSION_BUS_DEFAULT_ADDRESS CMake variable is no longer
838 supported; use the new DBUS_SESSION_BUS_LISTEN_ADDRESS and
839 DBUS_SESSION_BUS_CONNECT_ADDRESS variables instead.
841 • cmake/cross-compile.sh has been removed. Instead, please use a
842 cross-toolchain file (-DCMAKE_TOOLCHAIN_FILE) as documented at
843 <http://www.vtk.org/Wiki/CMake_Cross_Compiling>; or use Autotools
844 as documented in "info automake Cross-Compilation", and set
845 PKG_CONFIG_PATH appropriately.
849 • Man pages now require xmlto (or either xmlto or meinproc, if using CMake).
850 • man2html is no longer used.
854 • D-Bus Specification 0.20
855 · actually say that /org/freedesktop/DBus is the object that
856 implements o.fd.DBus (fd.o #51865, Colin Walters)
857 · various reorganisation for better clarity (fd.o #38252, Simon McVittie)
858 · stop claiming that all basic types work just like INT32 (strings don't!)
860 • The "source code" for the man pages is now Docbook XML, eliminating
861 the outdated duplicate copies used when building with CMake.
862 (fd.o #59805; Ralf Habacker, Simon McVittie)
866 • In the activation helper, when compiled for tests, do not reset the system
867 bus address, fixing the regression tests. (fd.o #52202, Simon)
869 • Fix building with Valgrind 3.8, at the cost of causing harmless warnings
870 with Valgrind 3.6 on some compilers (fd.o #55932, Arun Raghavan)
872 • Merge <servicehelper> from system-local.conf if necessary (fd.o #51560,

888 · Don't leak temporary fds pointing to /dev/null (fd.o #56927,
890 · Update sd-daemon.[ch] from systemd (fd.o #60681)
891 · Add partial support for QNX (fd.o #60339, fd.o #61176; Matt Fischer)
894 · The default session bus listening and connecting address is now
895 "autolaunch:", which makes D-Bus on Windows interoperate with itself
896 and GDBus "out of the box". Use the configure options and cmake variables
897 described above if you require a different autolaunch scope.
898 (fd.o #38201, Simon McVittie)
899 · Avoid a CMake warning under Cygwin (fd.o #59401, Ralf Habacker)
901 • Create session.d, system.d directories under CMake (fd.o #41319,
904 D-Bus 1.6.8 (2012-09-28)
907 The "Fix one thing, break another" release.
909 • Follow up to CVE-2012-3524: The additional hardening
910 work to use __secure_getenv() as a followup to bug #52202
911 broke certain configurations of gnome-keyring. Given
912 the difficulty of making this work without extensive
913 changes to gnome-keyring, use of __secure_getenv() is

929 D-Bus 1.6.4 (2012-07-18)
932 • Detect that users are "at the console" correctly when configured with
933 a non-default path such as --enable-console-auth-dir=/run/console
934 (fd.o #51521, Dave Reisner)

939 • Make --enable-developer default to "no" (regression in 1.6.2;
940 fd.o #51657, Simon McVittie)
943 · Launch dbus-daemon correctly if its path contains a space
944 (fd.o #49450, Wolfgang Baron)
946 D-Bus 1.6.2 (2012-06-27)
949 The "Ice Cabbage" release.

955 (fd.o #51032, Simon McVittie)
957 • Disconnect "developer mode" (assertions, verbose mode etc.) from
958 Automake maintainer mode. D-Bus developers should now configure with
959 --enable-developer. Automake maintainer mode is now on by default;
960 distributions can disable it with --disable-maintainer-mode.
961 (fd.o #34671, Simon McVittie)
963 • Automatically define DBUS_STATIC_BUILD in static-only Autotools builds,
964 fixing linking when targeting Windows (fd.o #33973; william, Simon McVittie)

969 D-Bus 1.6.0 (2012-06-05)
972 The “soul of this machine has improved” release.
974 This version starts a new stable branch of D-Bus: only bug fixes will
975 be accepted into 1.6.x. Other changes will now go to the 1.7.x branch.
977 Summary of changes since 1.4.x:

1016 Changes since 1.5.12:
1018 • Be more careful about monotonic time vs. real time, fixing DBUS_COOKIE_SHA1
1019 spec-compliance (fd.o #48580, David Zeuthen)

1022 non-root when using OpenBSD install(1) (fd.o #48217, Antoine Jacoutot)
1024 • Add missing commas in some tcp and nonce-tcp addresses, and remove
1025 an unused duplicate copy of the nonce-tcp transport in Windows builds
1026 (fd.o #45896, Simon McVittie)
1028 D-Bus 1.5.12 (2012-03-27)
1031 The “Big Book of Science” release.
1033 • Add public API to validate various string types:

1035 dbus_validate_error_name(), dbus_validate_bus_name(), dbus_validate_utf8()
1036 (fd.o #39549, Simon McVittie)
1038 • Turn DBusBasicValue into public API so bindings don't need to invent their
1039 own "union of everything" type (fd.o #11191, Simon McVittie)
1041 • Enumerate data files included in the build rather than using find(1)
1042 (fd.o #33840, Simon McVittie)

1049 on Win32, but not on WinCE (fd.o #46049, Simon McVittie)
1050 · fix duplicate case value when compiling against mingw-w64
1051 (fd.o #47321, Andoni Morales Alastruey)
1053 D-Bus 1.5.10 (2012-02-21)
1056 The "fire in Delerium" release.
1058 On Unix platforms, PTHREAD_MUTEX_RECURSIVE (as specified in POSIX 2008 Base
1059 and SUSv2) is now required.
1061 • D-Bus Specification 0.19:
1062 · Formally define unique connection names and well-known bus names,
1063 and document best practices for interface, bus, member and error names,
1064 and object paths (fd.o #37095, Simon McVittie)
1065 · Document the search path for session and system services on Unix, and
1066 where they should be installed by build systems (fd.o #21620, fd.o #35306;
1068 · Document the systemd transport (fd.o #35232, Lennart Poettering)
1070 • Make dbus_threads_init() use the same built-in threading implementation
1071 as dbus_threads_init_default(); the user-specified primitives that it
1072 takes as a parameter are now ignored (fd.o #43744, Simon McVittie)
1074 • Allow all configured auth mechanisms, not just one (fd.o #45106,
1077 • Improve cmake build system (Ralf Habacker):
1078 · simplify XML parser dependencies (fd.o #41027)
1079 · generate build timestamp (fd.o #41029)
1080 · only create batch files on Windows
1081 · fix option and cache syntax
1082 · add help-options target
1083 · share dbus-arch-deps.h.in with autotools rather than having our
1084 own version (fd.o #41033)
1086 • Build tests successfully with older GLib, as found in e.g. Debian 6
1087 (fd.o #41219, Simon McVittie)
1089 • Avoid use of deprecated GThread API (fd.o #44413, Martin Pitt)
1091 • Build documentation correctly if man2html doesn't support filenames on
1092 its command-line (fd.o #43875, Jack Nagel)
1094 • Improve test coverage. To get even more coverage, run the tests with
1095 DBUS_TEST_SLOW=1 (fd.o #38285, #42811; Simon McVittie)
1097 • Reduce the size of the shared library by moving functionality only used
1098 by dbus-daemon, tests etc. into their internal library and deleting
1099 unused code (fd.o #34976, #39759; Simon McVittie)
1101 • Add dbus-daemon --nopidfile option, overriding the configuration, for
1102 setups where the default configuration must include <pidfile/> to avoid
1103 breaking traditional init, but the pid file is in fact unnecessary; use
1104 it under systemd to improve startup time a bit (fd.o #45520,
1107 • Optionally (if configured --with-valgrind) add instrumentation to debug
1108 libdbus and associated tools more meaningfully under Valgrind
1109 (fd.o #37286, Simon McVittie)
1111 • Improve the dbus-send(1) man page (fd.o #14005, Simon McVittie)
1113 • Make dbus-protocol.h compatible with C++11 (fd.o #46147, Marc Mutz)
1115 • If tests are enabled and DBUS_MALLOC_CANNOT_FAIL is set in the environment,
1116 abort on failure to malloc() (like GLib does), to turn runaway memory leaks
1117 into a debuggable core-dump if a resource limit is applied (fd.o #41048,
1120 • Don't crash if realloc() returns NULL in a debug build (fd.o #41048,
1124 · Replace our broken reimplementation of recursive mutexes, which has
1125 been broken since 2006, with an ordinary pthreads recursive mutex
1126 (fd.o #43744; Sigmund Augdal, Simon McVittie)
1127 · Use epoll(7) for a more efficient main loop in Linux; equivalent patches
1128 welcomed for other OSs' equivalents like kqueue, /dev/poll, or Solaris
1129 event ports (fd.o #33337; Simon McVittie, Ralf Habacker)
1130 · When running under systemd, use it instead of ConsoleKit to check
1131 whether to apply at_console policies (fd.o #39609, Lennart Poettering)
1132 · Avoid a highly unlikely fd leak (fd.o #29881, Simon McVittie)
1133 · Don't close invalid fd -1 if getaddrinfo fails (fd.o #37258, eXeC001er)
1134 · Don't touch ~/.dbus and ~/.dbus-keyrings when running 'make installcheck'
1135 (fd.o #41218, Simon McVittie)
1136 · Stop pretending we respect XDG_DATA_DIRS for system services: the launch
1137 helper doesn't obey environment variables to avoid privilege escalation
1138 attacks, so make the system bus follow the same rules
1139 (fd.o #21620, Simon McVittie)
1142 · Find the dbus-daemon executable next to the shared library (fd.o #41558;
1143 Jesper Dam, Ralf Habacker)
1144 · Remove the faulty implementation of _dbus_condvar_wake_all (fd.o #44609,
1147 D-Bus 1.5.8 (2011-09-21)
1150 The "cross-metering" release.
1152 In addition to dead code removal and refactoring, this release contains all
1153 of the bugfixes from 1.4.16.
1155 • Clean up dead code, and make more warnings fatal in development builds
1156 (fd.o #39231, fd.o #41012; Simon McVittie)
1158 • If full test coverage is requested via --enable-tests, strictly require
1159 Python, pygobject and dbus-python, which are required by some tests; if not,
1160 and Python is missing, skip those tests rather than failing
1161 (fd.o #37847, Simon McVittie)
1163 • When using cmake, provide the same version-info API in the installed headers
1164 as for autotools (DBUS_VERSION, etc.) (fd.o #40905, Ralf Habacker)
1166 • Add a regression test for fd.o #38005 (fd.o #39836, Simon McVittie)
1168 • Make "NOCONFIGURE=1 ./autogen.sh" not run configure (Colin Walters)
1170 • Add _DBUS_STATIC_ASSERT and use it to check invariants (fd.o #39636,
1173 • Fix duplicates in authors list (Ralf Habacker)
1175 • Fix broken links from dbus-tutorial.html if $(htmldir) != $(docdir)
1176 (fd.o #39879, Chris Mayo)
1178 • Fix a small memory leak, and a failure to report errors, when updating
1179 a service file entry for activation (fd.o #39230, Simon McVittie)
1182 · Clean up (non-abstract) Unix sockets on bus daemon exit (fd.o #38656;
1183 Brian Cameron, Simon McVittie)
1184 · On systems that use libcap-ng but not systemd, drop supplemental groups
1185 when switching to the daemon user (Red Hat #726953, Steve Grubb)
1186 · Make the cmake build work again on GNU platforms (fd.o #29228,
1188 · Fix compilation on non-C99 systems that have inttypes.h but not stdint.h,
1189 like Solaris (fd.o #40313, Dagobert Michelsen)
1190 · Define CMSG_ALIGN, CMSG_LEN, CMSG_SPACE on Solaris < 10
1191 (fd.o #40235, Simon McVittie)
1192 · Cope with Unixes that don't have LOG_PERROR, like Solaris 10
1193 (fd.o #39987, Simon McVittie)
1194 · Cope with platforms whose vsnprintf violates both POSIX and C99, like
1195 Tru64, IRIX and HP-UX (fd.o #11668, Simon McVittie)
1198 · Fix compilation on MSVC, which doesn't understand "inline" with its
1199 C99 meaning (fd.o #40000; Ralf Habacker, Simon McVittie)
1200 · Fix misuse of GPid in test/dbus-daemon.c (fd.o #40003, Simon McVittie)
1201 · Fix cross-compilation to Windows with Automake (fd.o #40003, Simon McVittie)
1203 D-Bus 1.5.6 (2011-07-29)
1206 The "weird, gravy-like aftertaste" release.
1208 In addition to new features and refactoring, this release contains all of the
1209 bugfixes from 1.4.14.
1211 Potentially incompatible (Bustle and similar debugging tools will need
1212 changes to work as intended):
1214 • Do not allow match rules to "eavesdrop" (receive messages intended for a
1215 different recipient) by mistake: eavesdroppers must now opt-in to this
1216 behaviour by putting "eavesdrop='true'" in the match rule, which will
1217 not have any practical effect on buses where eavesdropping is not allowed
1218 (fd.o #37890, Cosimo Alfarano)
1222 • D-Bus Specification version 0.18 (fd.o #37890, fd.o #39450, fd.o #38252;
1223 Cosimo Alfarano, Simon McVittie)
1224 · add the "eavesdrop" keyword to match rules
1225 · define eavesdropping, unicast messages and broadcast messages
1226 · stop claiming that match rules are needed to match unicast messages to you
1227 · promote the type system to be a top-level section
1229 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
1230 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
1231 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
1233 • Consistently use atomic operations on everything that is ever manipulated
1234 via atomic ops, as was done for changes to DBusConnection's refcount in
1235 1.4.12 (fd.o #38005, Simon McVittie)
1237 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
1240 • Make "make check" in a clean tree work, by not running tests until
1241 test data has been set up (fd.o #34405, Simon McVittie)
1243 • The dbus-daemon no longer busy-loops if it has a very large number of file
1244 descriptors (fd.o #23194, Simon McVittie)
1246 • Refactor message flow through dispatching to avoid locking violations if
1247 the bus daemon's message limit is hit; remove the per-connection link cache,
1248 which was meant to improve performance, but now reduces it (fd.o #34393,
1251 • Some cmake fixes (Ralf Habacker)
1253 • Remove dead code, mainly from DBusString (fd.o #38570, fd.o #39610;
1254 Simon McVittie, Lennart Poettering)
1256 • Stop storing two extra byte order indicators in each D-Bus message
1257 (fd.o #38287, Simon McVittie)
1259 • Add an optional Stats interface which can be used to get statistics from
1260 a running dbus-daemon if enabled at configure time with --enable-stats
1261 (fd.o #34040, Simon McVittie)
1263 • Fix various typos (fd.o #27227, fd.o #38284; Sascha Silbe, Simon McVittie)
1265 • Documentation (fd.o #36156, Simon McVittie):
1266 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
1267 · install more documentation automatically, including man2html output
1268 · put dbus.devhelp in the right place (it must go in ${htmldir})
1271 · look for system services in /lib/dbus-1/system-services in addition to all
1272 the other well-known locations; note that this should always be /lib,
1273 even on platforms where shared libraries on the root FS would go in /lib64,
1274 /lib/x86_64-linux-gnu or similar (fd.o #35229, Lennart Poettering)
1275 · opt-in to fd passing on Solaris (fd.o #33465, Simon McVittie)
1277 • Windows-specific (Ralf Habacker):
1278 · fix use of a mutex for autolaunch server detection
1279 · don't crash on malloc failure in _dbus_printf_string_upper_bound
1281 D-Bus 1.5.4 (2011-06-10)
1284 Security (local denial of service):
1286 • Byte-swap foreign-endian messages correctly, preventing a long-standing
1287 local DoS if foreign-endian messages are relayed through the dbus-daemon
1288 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
1289 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
1293 • The constant to use for an infinite timeout now has a name,
1294 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
1295 which can be used for source compatibility with older versions of libdbus.
1297 • If GLib and DBus-GLib are already installed, more tests will be built,
1298 providing better coverage. The new tests can also be installed via
1299 ./configure --enable-installed-tests
1300 for system integration testing, if required. (fd.o #34570, Simon McVittie)
1304 • Consistently use atomic operations for the DBusConnection's refcount,
1305 fixing potential threading problems (fd.o #38005, Simon McVittie)
1307 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
1308 small (300KiB on x86-64) and it frequently doesn't work in unusual
1309 toolchains. To optimize for minimum installed size, you should benchmark
1310 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
1311 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
1313 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
1314 (fd.o #35880, Timothy Redaelli)
1316 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
1317 when not using a DESTDIR (fd.o #37870, Simon McVittie)
1319 • Windows-specific changes:
1320 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
1322 D-Bus 1.5.2 (2011-06-01)
1325 The "Boar Hunter" release.
1327 Notes for distributors:
1329 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
1330 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
1331 toolchain supports it reliably, via something like:
1333 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
1335 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
1339 • D-Bus Specification v0.17
1340 · Reserve the extra characters used in signatures by GVariant
1341 (fd.o #34529, Simon McVittie)
1342 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
1343 • Don't force -fPIE: distributions and libtool know better than we do whether
1344 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
1345 • Allow --disable-gc-sections, in case your toolchain offers the
1346 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
1347 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
1348 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
1349 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
1350 • Ensure that maintainers upload documentation with the right permissions
1351 (fd.o #36130, Simon McVittie)

1356 • Log messages dropped due to quotas to syslog (fd.o #35358,
1358 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
1359 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
1360 (fd.o #35228, Lennart Poettering)
1361 • In the regression tests, don't report fds as "leaked" if they were open
1362 on startup (fd.o #35173, Simon McVittie)
1363 • Make dbus-monitor bail out if asked to monitor more than one bus,
1364 rather than silently using the last one (fd.o #26548, Will Thompson)
1365 • Clarify documentation (fd.o #35182, Simon McVittie)
1366 • Clean up minor dead code and some incorrect error handling
1367 (fd.o #33128, fd.o #29881; Simon McVittie)
1368 • Check that compiler options are supported before using them (fd.o #19681,
1371 • Remove obsolete workaround for winioctl.h (fd.o #35083, Ralf Habacker)
1373 D-Bus 1.5.0 (2011-04-11)

1377 flying shark" release.
1379 • D-Bus Specification v0.16
1380 · Add support for path_namespace and arg0namespace in match rules
1381 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
1382 · Make argNpath support object paths, not just object-path-like strings,
1383 and document it better (fd.o #31818, Will Thompson)
1384 • Let the bus daemon implement more than one interface (fd.o #33757,
1386 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
1388 • Require user intervention to compile with missing 64-bit support
1389 (fd.o #35114, Simon McVittie)
1390 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
1391 • Raise UnknownObject instead of UnknownMethod for calls to methods on
1392 paths that are not part of the object tree, and UnknownInterface for calls
1393 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)
1395 D-Bus 1.4.8 (2011-04-08)
1398 The "It's like the beginning of a lobster" release.
1400 • Rename configure.in to configure.ac, and update it to modern conventions
1401 (fd.o #32245; Javier Jardón, Simon McVittie)
1402 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
1404 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
1405 --disable-x11-autolaunch configure option to prevent it altogether
1406 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
1407 • Install the documentation, and an index for Devhelp (fd.o #13495,
1408 Debian #454142; Simon McVittie, Matthias Clasen)
1409 • If checks are not disabled, check validity of string-like types and
1410 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
1411 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
1412 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
1413 • Break up a huge conditional in config-parser so gcov can produce coverage
1414 data (fd.o #10887, Simon McVittie)
1415 • List which parts of the Desktop Entry specification are applicable to
1416 .service files (fd.o #19159, Sven Herzberg)
1417 • Don't suppress service activation if two services have the same Exec=

1428 The "1, 2, miss a few, 99, 100" release.
1430 • Remove unfinished changes intended to support GTest-based tests,
1431 which were mistakenly included in 1.4.4
1433 D-Bus 1.4.4 (2010-02-17)
1436 • Switch back to using even micro versions for stable releases; 1.4.1
1437 should have been called 1.4.2, so skip that version number
1438 • Don't leave bad file descriptors being watched when spawning processes,
1439 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
1440 also LP#656134, LP#680444, LP#713157)
1441 • Check for MSG_NOSIGNAL correctly
1442 • Fix failure to detect abstract socket support (fd.o #29895)

1475 crash the bus. The existing restriction to 64-levels of nesting previously
1476 only applied to the static type signature; now it also applies to dynamic
1477 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
1479 • OS X portability fixes, including launchd support.
