New in 1.13:
+* Version requirements:
+
+ - Autoconf 2.65 or greater is required.
+
* Obsolete features removed:
- Use of the long-deprecated two- and three-arguments invocation forms
of the AM_INIT_AUTOMAKE is not supported anymore.
-New in 1.12.1:
+ - Support for the "Cygnus-style" trees (once enabled by the 'cygnus'
+ option) has been removed. See discussion about automake bug#11034
+ for more background.
-* WARNING: Future backward-incompatibilities!
+ - The automake-provided $(mkdir_p) make variable, @mkdir_p@ configure
+ time substitution and AM_PROG_MKDIR m4 macro have been removed. They
+ had been obsolete since automake 1.10, and actively deprecated since
+ Automake 1.12.1.
- - 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.
+ - The deprecated aclocal option '--acdir' has been removed. You
+ should use the options '--automake-acdir' and '--system-acdir'
+ instead (which have been introduced in Automake 1.11.2).
- - 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 parallel
- testsuite harness (previously only enabled by the 'parallel-tests'
- option) will become the default one; the older serial testsuite
- harness will still be available through the use of the 'serial-tests'
- option.
-
- - The following long-obsolete m4 macros will be removed in the
- next major Automake version (1.13):
+ - The following long-obsolete m4 macros have been removed:
AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
of the now-removed automatic de-ANSI-fication
support of Automake)
- - All the "old alias" macros in 'm4/obsolete.m4' will be removed in
- the next major Automake version (1.13).
+ - All the "old alias" macros in 'm4/obsolete.m4' have been removed.
+
+* Changes to Automake-generated testsuite harnesses:
+
+ - The parallel testsuite harness (previously only enabled by the
+ 'parallel-tests' option) is the default one; the older serial
+ testsuite harness will still be available through the use of the
+ 'serial-tests' option (introduced in Automake 1.12).
+
+* Silent rules support:
+
+ - Support for silent rules is now always active in Automake-generated
+ Makefiles. So, although the verbose output is still the default,
+ the user can now always use "./configure --enable-silent-rules" or
+ "make V=0" to enable quieter output in the package he's building.
+
+ - The 'silent-rules' option has now become a no-op, preserved for
+ backward-compatibility only. In particular, its use does not disable
+ the warnings in the 'portability-recursive' category anymore.

- 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).
- - The '--acdir' option of aclocal is deprecated, and will probably
- be removed in the next major Automake release (1.13). You should
- use the options '--automake-acdir' and '--system-acdir' instead
- (which have been introduced in Automake 1.11.2).
-
- The exact order in which the directories in the aclocal macro
search path are looked up is probably going to be changed in the
next Automake release (1.13).
m4 macro are deprecated, eliciting a warning in the 'obsolete'
category. They will be removed in the next major version (1.13).
+* Miscellaneous changes:
+
+ - The Automake test cases now require a proper POSIX-conforming shell.
+ Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) won't be
+ accepted anymore. In most cases, the user shouldn't have to specify
+ such POSIX shell explicitly, since it will be looked up at configure
+ time. Still, when this lookup fails, or when the user wants to
+ override its conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be
+ used (pointing to the shell that will be used to run the Automake
+ test cases).
+
Bugs fixed in 1.12.1:
* Bugs introduced by 1.12:
- Several inefficiencies and poor performances in the implementation
of the parallel-tests 'check' and 'recheck' targets have been fixed.
+ - The post-processing of output "#line" directives done the ylwrap
+ script is more faithful w.r.t. files in a subdirectory; for example,
+ if the processed file is "src/grammar.y", ylwrap will correctly
+ produce directives like:
+ #line 7 "src/grammar.y"
+ rather than like
+ #line 7 "grammar.y"
+ as it did before.
