- Autoconf 2.65 or greater is required.
+ - The rules to build PDF and DVI output from Texinfo input now
+ requires Texinfo 4.9 or later.
+
* Obsolete features removed:
+ - Use of the long-deprecated two- and three-arguments invocation forms
+ of the AM_INIT_AUTOMAKE is not supported anymore.
+
- Support for the "Cygnus-style" trees (once enabled by the 'cygnus'
option) has been removed. See discussion about automake bug#11034
for more background.
- 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
backward-compatibility only. In particular, its use does not disable
the warnings in the 'portability-recursive' category anymore.
+* Texinfo Support:
+
+ - The rules to build PDF and DVI files from Texinfo input now use the
+ ' --build-dir' option, to keep the auxiliary files used by texi2dvi
+ and texi2pdf around without cluttering the build directory, and to
+ make it possible to run the "dvi" and "pdf" recipes in parallel.
+
+* Automatic remake rules and 'missing' script:
+
+ - The 'missing' script does 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+ of out-of-date files that require a maintainer-specific tool to be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). It just give a useful warning, and in some cases also a tip
+ about how to obtain such a tool.
+
+ - The missing script has thus become useless as a (poor) way to work
+ around the sketched-timestamps issues that can happen for projects
+ that keep generated files committed in their VCS repository. Such
+ projects are now encouraged to write a custom "fix-timestamps.sh"
+ script to avoid such issues; a simple example is provided in the
+ "CVS and generated files" chapter of the automake manual.

+New in 1.12.2:
* WARNING: Future backward-incompatibilities!
+ - 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.
+
- 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
search path are looked up is probably going to be changed in the
next Automake release (1.13).
+* 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.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.12.1:
+
* New supported languages:
- Support for Objective C++ has been added; it should work similarly to
- 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.
+
+* Bugs with new Perl versions:
+
+ - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
