* WARNING: Future backward-incompatibilities!
- - Starting from either the next minor version (1.12.2) or the next major
- version (1.13), Automake will start warning if 'configure.in' is used
- instead of 'configure.ac' as the Autoconf input. Future versions of
- Automake will drop support for 'configure.in' altogether.
+ - Future versions of Automake will likely drop support for the
+ long-deprecated 'configure.in' name for the Autoconf input file.
+ You are advised to use the recommended name 'configure.ac' instead.
+
+ - The long-obsolete (since automake 1.10) AM_PROG_MKDIR m4 macro will
+ be removed in Automake 1.13. The $(mkdir_p) make variable and the
+ @mkdir_p@ substitution will still remain available (as aliases of
+ $(MKDIR_P)) for the moment, for better backward compatibility.
- Autoconf 2.65 or later will be required by the next major Automake
version (1.13). Until now, Automake has required Autoconf version
2.62 or later.
- - Starting from the next major Automake version (1.13), the rules to
- build pdf, ps and dvi output from Texinfo input will use the '--tidy'
- option by default. Since such an option was introduced in Texinfo
- 4.9, this means that Makefiles generated by future Automake versions
- will require at least that version of Texinfo.
+ - Starting from the next major Automake version (1.13), the rules
+ to build pdf, ps and dvi output from Texinfo input will use the
+ '--build-dir' option by default. Since such an option was only
+ introduced in Texinfo 4.9, this means that Makefiles generated by
+ future Automake versions will require at least that version of
+ Texinfo.
- Starting from the next major Automake version (1.13), the parallel
testsuite harness (previously only enabled by the 'parallel-tests'
the next major Automake version (1.13).
- Support for the two- and three-arguments invocation forms of the
- AM_INIT_AUTOMAKE macro will be deprecated in the next minor version
- of Automake (1.12.1) and removed in the next major version (1.13).
+ AM_INIT_AUTOMAKE macro is deprecated, and will be removed in the
+ next major Automake version (1.13).
- The '--acdir' option of aclocal is deprecated, and will probably
be removed in the next major Automake release (1.13). You should
search path are looked up is probably going to be changed in the
next Automake release (1.13).
+ - The 'missing' script will not try anymore to update the timestamp
+ of out-of-date files that require a maintainer-specific tool to be
+ remade, in case the user lacks such a tool (or has a too-old version
+ of it). In fact, starting from Automake 1.13, all it'll do will be
+ giving more useful warnings than a bare "command not found" from a
+ make recipe would.
+
+* M4 files:
+
+ - The '.m4' files provided by Automake does not define serial numbers
+ anymore. This should cause no difference in the behaviour of aclocal
+ though.
+
+* Automake Testsuite:
+
+ - Some testsuite weaknesses and spurious failures have been fixed.
+
+* Long-standing bugs:
+
+ - Instead of renaming only self-references of files (typically for
+ #lines), ylwrap now also renames references to the other generated
+ files. This fixes support for GLR and C++ parsers from Bison (PR
+ automake/491 and automake bug#7648): 'parser.c' now properly
+ #includes 'parser.h' instead of 'y.tab.h'.
+
+ - Generated files unknown to ylwrap are now preserved. This fixes
+ C++ support for Bison (automake bug#7648): location.hh and the
+ like are no longer discarded.
+
+New in 1.12.2:
+
+* Warnings and deprecations:
+
+ - Automake now issues a warning (in the 'portability' category) if
+ 'configure.in' is used instead of 'configure.ac' as the Autoconf
+ input file. Such a warning will also be present in the next
+ Autoconf version (2.70).
+
+* Cleaning rules:
+
+ - Recursive cleaning rules descends into the $(SUBDIRS) in the natural
+ order (as done by the other recursive rules), rather than in the
+ inverse order. They used to do that in order to work a round a
+ limitation in an older implementation of the automatic dependency
+ tracking support, but that limitation had been lifted years ago
+ already, when the automatic dependency tracking based on side-effects
+ of compilation had been introduced.
+
+ - Cleaning rules for compiled objects (both "plain" and libtool) work
+ better when subdir objects are involved, not triggering a distinct
+ 'rm' invocation for each such object. They do so by removing *any*
+ compiled object file that is in the same directory of a subdir
+ object. See automake bug#10697.
+
+* Silent rules support:
+
+ - A new predefined $(AM_V_P) make variable is provided; it expands
+ to a shell conditional that can be used in recipes to know whether
+ make is being run in silent or verbose mode.
+
+Bugs fixed in 1.12.2:
+
+* SECURITY VULNERABILITIES!
+
+ - The 'distcheck' recipe no longer grants temporary world-write
+ permissions on the extracted distdir. Even if such rights were
+ only granted for a vanishingly small time window, the implied
+ race condition proved to be enough to allow a local attacker
+ to run arbitrary code with the privileges of the user running
+ "make distcheck". This is CVE-2012-3386.
+
+* Long-standing bugs:
+
+ - The "recheck" targets behaves better in the face of build failures
+ related to previously failed tests. For example, if a test is a
+ compiled program that must be rerun by "make recheck", and its
+ compilation fails, it will still be rerun by further "make recheck"
+ invocations. See automake bug#11791.
+
+* Bugs introduced by 1.12.1:
+
+ - Automake provides once again the '$(mkdir_p)' make variable and the
+ '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'),
+ for better backward-compatibility.

+
+New in 1.12.1:
+
* New supported languages:
- Support for Objective C++ has been added; it should work similarly to
- The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
m4 macro are deprecated, eliciting a warning in the 'obsolete'
- category. They will be removed in the next major version (1.13).
+ category.
* Miscellaneous changes:
#line 7 "grammar.y"
as it did before.
+* Bugs with new Perl versions:
+
+ - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
