This is to announce GNU Automake 1.17, a stable release. [Thanks to Karl Berry for doing so much of work, preparing for this release and even writing most of the following. ]
This release changes AM_PATH_PYTHON to prefer Python 3 to Python 2 (set PYTHON beforehand to override the searching), among plenty of other modernizations and fixes. See the NEWS below for a brief summary of changes. Apart from the above Python change, forced on us by the Python world, our hope and intent is that it does not create incompatibilities with previous releases. Indeed, many of the changes in this release were made purely to improve portability. But of course bugs are always possible, so please report problems, e.g., if your build setup worked with an older Automake but fails with 1.17.

If a specific version of Python 2 is still needed, the $PYTHON variable should be set beforehand. - AM_PATH_PYTHON will also search for Python versions 3.20 through 3.10. It previously searched for 3.9 through 3.0. (bug#53530) - RANLIB may be overridden on a per-target basis. - AM_TEXI2FLAGS may be defined to pass extra flags to TEXI2DVI & TEXI2PDF. - New option "posix" to emit the special target .POSIX for make. (bug#55025, bug#67891) - Systems with non-POSIX "rm -f" behavior are now supported, and the prior intent to drop support for them has been reversed. The ACCEPT_INFERIOR_RM_PROGRAM setting no longer exists. (bug#10828) - Variables using escaped \# will trigger portability warnings, but be retained when appended. GNU Make & BSD Makes are known to support it. (bug#7610) - GNU Make's default pattern rules are disabled, for speed and debugging. (.SUFFIXES was already cleared.) (bug#64743) - For Texinfo documents, if a .texi.in file exists, but no .texi, the .texi.in will be read. Texinfo source files need not be present at all, and if present, need not contain @setfilename. Then the file name as given in the Makefile.am will be used. If @setfilename is present, it should be the basename of the Texinfo file, extended with .info. (bug#54063) - aclocal has a new option --aclocal-path to override $ACLOCAL_PATH. (https://lists.gnu.org/archive/html/automake-patches/2022-01/msg00029.html) - The missing script also supports autoreconf, autogen, and perl. (https://lists.gnu.org/archive/html/automake-patches/2015-08/msg00000.html) - test-suite.log now contains basic system information, and the console message about bug reporting on failure has a bit more detail. (bug#68746, bug#71421) - When using the (default) "parallel" test driver, you can now omit the output of skipped tests from test-suite.log by defining the variable IGNORE_SKIPPED_LOGS to a non-empty value. (bug#71422) * Bugs fixed - Generated file timestamp checks handle filesystems with subsecond timestamp granularity dynamically, greatly speeding up the sleep done by AC_OUTPUT when generating config.status (all packages) and Automake's make check. However, this subsecond-mtime support requires an autom4te from Autoconf 2.72 or later (or random test failures and other timing problems may ensue), as well as a Perl, sleep program, make program, and filesystem that all support subsecond resolution; otherwise, we fall back to a two-second granularity, not even testing the (common) 1s case since that would induce a 2s delay for all configure scripts in all packages on all systems that don't support subsecond mtimes. When everything is supported, a line "Features: subsecond-mtime" is now printed by automake --version and autom4te --version. To override this check and delay, e.g. to use 1 second: am_cv_filesystem_timestamp_resolution=1 export am_cv_filesystem_timestamp_resolution (commit 720a11531, https://lists.gnu.org/archive/html/automake-commit/2022-02/msg00009.html then bug#60808, bug#64756, bug#67670, bug#68808, bug#71652, history reviewed in https://lists.gnu.org/archive/html/automake/2024-06/msg00054.html and more info in surrounding threads.) - The default value of $ARFLAGS is now "cr" instead of "cru", to better support deterministic builds. (bug#20082) - Automake's make dist now uses -9 instead of --best with gzip, because Alpine gzip does not support --best. Also, GZIP_ENV is used only for compression, not decompression, because of the same system. (bug#68151) - Dependency files are now empty, instead of "# dummy", for speed. (https://lists.gnu.org/archive/html/automake/2022-05/msg00006.html) - Compiling Python modules with Python 3.5+ uses multiple optimization levels. (bug#38043) - If the Python installation "scheme" is set to posix_local (Debian), it is reset to either deb_system (if the prefix = /usr), or posix_prefix (otherwise). (bug#54412, bug#64837) - As a result of the Python scheme change, the installation directory for Python files again defaults to "site-packages" under the usual installation prefix, even on systems (generally Debian-based) that would normally use the "dist-packages" subdirectory under /usr/local. - When compiling Emacs Lisp files, emacs is run with --no-site-file to disable user config files that might hang or access the terminal; and -Q is not used, since its support and behavior varies. (bug#58102) - Emacs Lisp compilations respect silent make output. - Automake no longer incorrectly warns that the POSIX make variables $(*D) and the like are non-POSIX. Unfortunately, the make implementations which do not correctly implement all the POSIX variables are not detected, but this seems to have little impact in practice. (bug#9587) - Pass libtool tags OBJC and OBJCXX for the respective languages. (bug#67539) - distcleancheck ignores "silly rename" files (.nfs* .smb* .__afs*) that can show up on network file systems. (https://lists.gnu.org/archive/html/automake/2022-09/msg00002.html) - Pass any options given to AM_PROG_LEX on to AC_PROG_LEX. (bug#65600, bug#65730) - aclocal: recognize ; as path separator on OS/2 and Windows. (bug#71534) - Hash iterations with external effects now consistently sort keys. (bug#25629, bug#46744) - tests: avoid some declaration conflicts for lex et al. on SunOS. (bug#34151 and others) - tests: declare yyparse before use and use (void) parameter lists instead of (), to placate C23. (bug#71425) - Typos in code and other doc fixes. (bug#68003, bug#68004, et al.) * Obsolescence: - py-compile no longer supports Python 0.x or 1.x versions. Python 2.0, released in 2000, is currently the minimum required version.
