3 - Autoconf 2.59a is required.
5 - Perl 5.6 or greater is required.
7 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
9 - The rebuild rules for distributed Yacc and Lex output will avoid
10 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
13 - Preprocessed assembler (*.S) compilation now honnors CPPFLAGS,
14 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
15 tracking, unlike non-preprocessed assembler (*.s).
17 - Libtool generic flags (those that go before the --mode=MODE option)
18 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
20 - aclocal now also supports -Wmumble and -Wno-mumble options.
24 * Makefile.in bloat reduction:
26 - Inference rules are used to compile sources in subdirectories when
27 the `subdir-objects' option is used and no per-target flags are
28 used. This should reduce the size of some projects a lot, because
29 Automake used to output an explicit rule for each such object in
32 - Automake no longer outputs three rules (.o, .obj, .lo) for each
33 object that must be built with explicit rules. It just outputs
34 the rules required to build the kind of object considered: either
35 the two .o and .obj rules for usual objects, or the .lo rule for
38 * Change to Libtool support:
40 - Libtool tags are used with libtool versions that support them.
41 (I.e., with Libtool 1.5 or greater.)
43 - Automake is now able to handle setups where a libtool library is
44 conditionally installed in different directories, as in
47 lib_LTLIBRARIES = liba.la
49 pkglib_LTLIBRARIES = liba.la
55 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
56 really evaluated, before it decides to include them in aclocal.m4.
57 This solves nasty problems with conditional redefinitions of
58 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
59 *.m4 files to be included in any project using these macros.
60 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
61 most famous instance of this bug.)
63 - Do not complain about missing conditionally AC_REQUIREd macros
64 that are not actually used. In 1.8.x aclocal would correctly
65 determine which of these macros were really needed (and include
66 only these in the package); unfortunately it would also require
67 all of them to be present in order to run. This created
68 situations were aclocal would not work on a tarball distributing
69 all the macros it uses. For instance running aclocal on a project
70 containing only the subset of the Gettext macros in use by the
71 project did not work, because gettext conditionally requires other
74 * Portability improvements:
76 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
77 tar-pax. The new option filename-length-max=99 helps diagnosing
78 filenames that are too long for tar-v7. (PR/414)
80 - Variables aumented with `+=' are now automatically flattened (i.e.,
81 trailing backslashes removed) and then wrapped around 80 colummns
82 (adding trailing backslashes). In previous versions, a long series
88 would result in a single-line definition of VAR that could possibly
89 exceed the maximum line length of some make implementations.
91 Non-augmented variables are still output as they are defined in
96 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
97 Works the same as the old Fortran 77 implementation; just replace
98 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
99 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
101 - Support for conditional _LISP.
103 - Support for conditional -hook and -local rules (PR/428).
105 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
107 - Automake will not write any Makefile.ins after the first error it
108 encounters. The previous Makefile.ins (if any) will be left in
109 place. (Warnings will not prevent output, but remember they can
110 be turned into errors with -Werror.)
112 - The restriction that SUBDIRS must contain direct children is gone.
115 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
116 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
120 * Long standing bugs:
122 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
123 so that `make distclean' and `make maintainer-clean' can work.
125 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
127 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
129 - Polish diagnostic when no input file is found.
133 * Long standing bugs:
135 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
136 overridden by the user.
138 - Honor PATH_SEPARATOR in various places of the Automake package, for
141 - Adjust dependency tracking mode detection to ICC 8.0's new output.
144 - Fix install-sh so it can install the `mv' binary... using `mv'.
146 - Fix tru64 dependency tracking for libtool objects.
148 - Work around Exuberant Ctags when creating a TAGS files in a directory
149 without files to scan but with subdirectories to include.
151 * Bugs introduced by 1.8:
153 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
154 not defined in the same conditions as the _LDADD that uses it.
156 - Do not warn when JAVAROOT is overridden, this is legitimate.
160 * Long standing bugs:
162 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
163 or any of the other *dir variables contain a space.
165 Please note that Automake does not and cannot support spaces in
166 filenames that are involved during the build. This change affects
167 only installation paths, so that `make install' does not bomb out
168 in packages configured with
169 ./configure --prefix '/c/Program Files'
171 - Fix the depfiles output so it works with GNU sed (<4.1) even when
172 POSIXLY_CORRECT is set.
174 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
175 since Autoconf 2.54, which defines LIBOBJS itself.
177 - Fix a potential (but unlikely) race condition in parallel elisp
178 builds. (Introduced in 1.7.3.)
180 - Do not assume that users override _DEPENDENCIES in all conditions
181 where Automake will try to define them.
183 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
184 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
187 This fix also affects the $(mkdir_p) variable defined since
188 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
189 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
191 - Secure temporary directory creation in `make distcheck'. (PR/413)
193 - Do not generate two build rules for `parser.h' when the
194 parser appears in two different conditionals.
196 - Work around a Solaris 8 /bin/sh bug in the test for dependency
197 checking. Usually ./configure will not pick this shell; so this
198 fix only helps cases where the shell is forced to /bin/sh.
200 * Bugs introduced by 1.8:
202 - In some situations (hand-written `m4_include's), aclocal would
203 call the `File::Spec->rel2abs' method, which was only introduced
204 in Perl 5.6. This new version reestablish support Perl 5.005.
206 It is likely that the next major Automake releases will require at
207 least Perl 5.6. Consider upgrading your development environment
208 if you are still using the five-year-old Perl 5.005.
210 - Automake would sometimes fail to define rules for targets listed
211 in variables defined in multiple conditions. For instance on
217 it would define only the `a.$(OBJEXT): a.c' rule and omit the
218 `b.$(OBJEXT): b.c' rule.
220 * New sections in manual:
222 - Third-Party Makefiles: how to interface third party Makefiles.
223 - Upgrading: upgrading packages to newer Automake versions.
224 - Multiple Outputs: handling tools that produce many outputs.
228 * A (well known) portability bug slipped in the changes made to
229 install-sh in Automake 1.8.1. The broken install-sh would refuse to
230 install anything on Tru64.
232 * Fix install rules for conditionally built python files. (This never
237 * Bugs introduced by 1.8:
239 - Fix Config.pm import error with old Perl versions (at least
240 5.005_03). One symptom is that aclocal could not find its macro
243 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
244 created by `make install' are always world readable, even if the
245 installer happens to have an overly restrictive umask (e.g. 077).
246 This was a mistake and has been reverted. There are at least two
247 reasons why we must not use `-m 0755':
248 - it causes special bits like SGID to be ignored,
249 - it may be too restrictive (some setups expect 775 directories).
251 - Fix aclocal to honor definitions located in files which have been
252 m4_included manually. aclocal 1.8 had been updated to check
253 m4_included files for new requirements, but forgot that these
254 m4_included files can also provide new definitions.
256 Note that if you have such a setup, we recommend you get rid of
257 it. In the past, there was a reason to m4_include files manually:
258 aclocal used to duplicate entire M4 files into aclocal.m4, even
259 files that were distributed. Some packages were therefore
260 m4_including the distributed file directly, and playing some
261 tricks to ensure aclocal would not copy that file to aclocal.m4,
262 in order to limit the amount of duplication. Since aclocal 1.8.x
263 will precisely output m4_includes for local M4 files, we recommend
264 that you clean up your setup, removing all manual m4_includes and
265 letting aclocal output them.
267 - Output detailed menus in the Info version if the Automake manual,
268 so that Emacs can locate the indexes.
270 - configure.ac and configure were listed twice in DIST_COMMON (an
271 internal variable where Automake lists configury files to
272 distribute). This was harmless, but unaesthetic.
274 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
275 This was an issue only in the Automake package itself, not in
278 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
279 DEST:SRC. This was wrong, as some packages do
280 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
283 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
284 argument. This caused two kinds of failures:
285 - Rules installing data in a conditionally defined directory
286 failed when that directory was undefined. In this case no
287 argument was supplied.
288 - `make installdirs' failed, because several directories were
289 passed to $(mkdir_p). This was an issue only on platform
290 were $(mkdir_p) is implemented with `install-sh -d'.
291 $(mkdir_p) as been changed to accept 0 or more arguments, as
294 * Long-standing bugs:
296 - Fix an unexpected diagnostic occurring when users attempt
297 to override some internal variables that Automake appends to.
299 - aclocal now scans configure.ac for macro definitions (PR/319).
301 - Fix a portability issue with OSF1/Tru64 Make. If a directory
302 distributes files which are outside itself (this usually occurs
303 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
304 from a parent package), then `make distcheck' fails due to an
305 optimization performed by OSF1/Tru64 Make in its VPATH handling.
306 (tests/subpkg2.test failure)
308 - Fix another portability issue with Sun and OSF1/Tru64 Make.
309 In a VPATH-build configuration, `make install' would install
310 nobase_ files to wrong locations.
312 - Fix a Perl `uninitialized value' diagnostic occurring when
313 automake complains that a Texinfo file does not have a
314 @setfilename statement.
316 - Erase config.status.lineno during `make distclean'. This file
317 can be created by config.status. Automake already knew about
318 configure.lineno, but forgot config.status.lineno.
320 - Distribute all files, even those which are built and installed
321 conditionally. This change affects files listed in conditionally
322 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
323 as well as those listed in conditionally defined dist_*_DATA,
324 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
326 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
327 doesn't conform to POSIX.
329 - Normalize help strings for configure variables and options added
334 - Check for python2.4 in AM_PATH_PYTHON.
336 * Spurious failures in test suite:
338 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
339 tests/ltconv.test: fix failures with CVS Libtool.
340 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
341 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
342 fix failures with old Texinfo versions.
348 - The NEWS file is more verbose.
352 - Autoconf 2.58 or greater is required.
356 - Default source file names in the absence of a _SOURCES declaration
357 are made by removing any target extension before appending `.c', so
358 to make the libtool module `foo.la' from `foo.c', you only need to
361 lib_LTLIBRARIES = foo.la
362 foo_la_LDFLAGS = -module
364 For backward compatibility, foo_la.c will be used instead of
365 foo.c if this file exists or is the explicit target of a rule.
366 However -Wobsolete will warn about this deprecated naming.
368 - AR's `cru' flags are now set in a global ARFLAGS variable instead
369 of being hard-coded in each $(AR) invocation, so they can be
370 substituted from configure.ac. This has been requested by people
371 dealing with non-POSIX ar implementations.
373 - New warning option: -Woverride. This will warn about any user
374 target or variable definitions which override Automake
377 - Texinfo rules back up and restore info files when makeinfo fails.
379 - Texinfo rules now support the `html' target.
380 Running this requires Texinfo 4.0 or greater.
382 `html' is a new recursive target, so if your package mixes
383 hand-crafted `Makefile.in's with Automake-generated
384 `Makefile.in's, you should adjust the former to support (or
385 ignore) this target so that `make html' recurses successfully. If
386 you had a custom `html' rule in your `Makefile.am', it's better to
387 rename it as `html-local', otherwise your rule will override
388 Automake's new rule (you can check that by running `automake
389 -Woverride') and that will stop the recursion to subdirectories.
391 Last but not least, this `html' rule is declared PHONY, even when
392 overridden. Fortunately, it appears that few packages use a
393 non-PHONY `html' rule.
395 - Any file which is m4_included from configure.ac will appear as a
396 configure and Makefile.in dependency, and will be automatically
399 - The rules for rebuilding Makefiles and Makefile.ins will now
400 rebuild all Makefiles and all Makefile.ins at once when one of
401 configure's dependencies has changed. This is considerably faster
402 than previous implementations, where config.status and automake
403 were run separately in each directory (this still happens when you
404 change a Makefile.am locally, without touching configure.ac or
405 friends). Doing this also solves a longstanding issue: these
406 rebuild rules failed to work when adding new directories to the
407 tree, forcing you to run automake manually.
409 - For similar reasons, the rules to rebuild configure,
410 config.status, and aclocal.m4 are now defined in all directories.
411 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
412 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
413 should better define them in all directories. This is easily done
414 using an AC_SUBST (make sure you prefix these dependencies with
415 $(top_srcdir) since this variable will appear at different
416 levels of the build tree).
418 - aclocal will now use `m4_include' instead of copying local m4
419 files into aclocal.m4. (Local m4 files are those you ship with
420 your project, other files will be copied as usual.)
422 Because m4_included files are automatically distributed, it means
423 for most projects there is no point in EXTRA_DISTing the list of
424 m4 files which are used. (You can probably get rid of
425 m4/Makefile.am if you had one.)
427 - aclocal will avoid touching aclocal.m4 when possible, so that
428 Autom4te's cache isn't needlessly invalidated. This behavior can
429 be switched off with the new `--force' option.
431 - aclocal now uses Autoconf's --trace to detect macros which are
432 actually used and will no longer include unused macros simply
433 because they where mentioned. This was often the case for macros
434 called conditionally.
436 - New options no-dist and no-dist-gzip.
438 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
439 py-compile, and ylwrap, now all understand --version and --help.
441 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
442 links as part of the distclean target and including source files in
445 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
446 argument. The latter can be used to override the default behavior
449 - Automake will exit with $? = 63 on version mismatch. (So does
450 Autoconf 2.58) missing knows this, and in this case it will
451 emulate the tools as if they were absent. Because older versions
452 of Automake and Autoconf did not use this exit code, this change
453 will only be useful in projects generated with future versions of
456 - When using AC_CONFIG_FILES with multiple input files, Automake
457 generates the first ".in" input file for which a ".am" exists.
458 (Former versions would try to use only the first input file.)
460 - lisp_DATA is now allowed. If you are using the empty ELCFILES
461 idiom to disable byte-compilation of lisp_LISP files, it is
462 recommended that you switch to using lisp_DATA. Note that
463 this is not strictly equivalent: lisp_DATA will install elisp
464 files even if emacs is not installed, while *_LISP do not
465 install anything unless emacs is found.
467 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
468 available. This selection is achieved through the Makefile
469 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
470 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
471 `$(install_sh) -m 0755 -d'.
475 - Because `mkdir -p' is available on most platforms, and we can use
476 `install-sh -d' when it is not, the use of the mkinstalldirs
477 script is being phased out. `automake --add-missing' no longer
478 installs it, and if you remove mkinstalldirs from your package,
479 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
481 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
482 gettextize and autopoint will install it when needed. Automake
483 will continue to define the $(mkinstalldirs) and to distribute
484 mkinstalldirs when this script is in the source tree.
486 - AM_PROG_CC_STDC is now empty. The content of this macro was
487 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
488 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
489 renaming should be safe, even if you have to support several,
490 versions of Automake, because AC_PROG_CC defines this variable
491 since Autoconf 2.54.)
493 - Some users where using the undocumented ACLOCAL_M4_SOURCES
494 variable to override the aclocal.m4 dependencies computed
495 (inaccurately) by older versions of Automake. Because Automake
496 now tracks configure's m4 dependencies accurately (see m4_include
497 above), the use of ACLOCAL_M4_SOURCES should be considered
498 obsolete and will be flagged as such when running `automake
503 - Defining programs conditionally using Automake conditionals no
504 longer leads to a combinatorial explosion. The following
505 construct used to be troublesome when used with dozens of
520 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
522 - Due to implementation constraints, previous versions of Automake
523 proscribed multiple conditional definitions of some variables
533 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
534 This restriction has been lifted, and these variables now
535 support multiple conditional definitions as do other variables.
537 - Cleanup the definitions of $(distdir) and $(top_distdir).
538 $(top_distdir) now points to the root of the distribution
539 directory created during `make dist', as it did in Automake 1.4,
540 not to the root of the build tree as it did in intervening
541 versions. Furthermore these two variables are now only defined in
542 the top level Makefile, and passed to sub-directories when running
545 - The --no-force option now correctly checks the Makefile.in's
546 dependencies before deciding not to update it.
548 - Do not assume that make files are called Makefile in cleaning rules.
550 - Update .info files in the source tree, not in the build tree. This
551 is what the GNU Coding Standard recommend. Only Automake 1.7.x
552 used to update these files in the build tree (previous versions did
553 it in the source tree too), and it caused several problems, varying
554 from mere annoyance to portability issues.
556 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
557 when --add-missing and --force-missing are used. For backward
558 compatibility --add-missing will continue to install COPYING (in
559 `gnu' strictness) when none of these three files exist, but this
560 use is deprecated: you should better choose a license yourself and
561 install it once for all in your source tree (and in your code
564 - Fix ylwrap so that it does not overwrite header files that haven't
565 changed, as the inline rule already does.
567 - User-defined rules override automake-defined rules for the same
568 targets, even when rules do not have commands. This is not new
569 (and was documented), however some of the automake-generated
570 rules have escaped this principle in former Automake versions.
571 Rules for the following targets are affected by this fix:
573 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
574 info, info-am, install-data-am, install-exec-am, install-info,
575 install-info-am, install-man, installcheck-am, maintainer-clean,
576 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
577 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
579 Practically it means that an attempt to supplement the dependencies
580 of some target, as in
584 will now *silently override* the automake definition of the
585 rule for this target. Running `automake -Woverride' will diagnose
586 all such overriding definitions.
588 It should be noted that almost all these targets support a *-local
589 variant that is meant to supplement the automake-defined rule
590 (See node `Extending' in the manual). The above rule should
593 clean-local: my-clean-rule
595 These *-local targets have been documented since at least
596 Automake 1.2, so you should not fear the change if you have
597 to support multiple automake versions.
601 - The Automake manual is now distributed under the terms of the GNU FDL.
603 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
605 - core dumps are no longer removed by the cleaning rules. There are
606 at least three reasons for this:
607 1. These files should not be created by any build step,
608 so their removal do not fit any of the cleaning rules.
609 Actually, they may be precious to the developer.
610 2. If such file is created during a build, then it's clearly a
611 bug Automake should not hide. Not removing the file will
612 cause `make distcheck' to complain about its presence.
613 3. Operating systems have different naming conventions for
614 core dump files. A core file on one system might be a
615 completely legitimate data file on another system.
617 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
618 defined by Automake. This means that any definition in the
619 environment will be used, unless overridden in the Makefile.am or
620 on the command line. The old behavior, where these variables were
621 defined empty in each Makefile, can be obtained by AC_SUBSTing or
622 AC_ARG_VARing each variable from configure.ac.
624 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
625 documented. (The is not a new feature, these variables have
626 been there since at least Automake 1.4.)
629 * Fix install-strip to work with nobase_ binaries.
630 * Fix renaming of #line directives in ylwrap.
631 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
634 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
635 * Fix detection of Debian's install-info, broken since version 1.5.
636 (Debian bug #213524).
637 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
638 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
641 * The implementation of automake's --no-force option is unreliable,
642 so this option is ignored in this version. A real fix will appear in
643 Automake 1.8. (Debian Bug #206299)
644 * AM_PATH_PYTHON: really check the whole list of interpreters if no
645 argument is given. (PR/399)
646 * Do not warn about leading `_' in variable names, even with -Wportability.
647 * Support user redefinitions of TEXINFO_TEX.
648 * depcomp: support AIX Compiler version 6.
649 * Fix missing rebuilds during `make dist' with BSD make.
650 (Could produce tarballs containing out-of-date files.)
651 * Resurrect multilib support.
652 * Noteworthy manual updates:
653 - Extending aclocal: how to write m4 macros that won't trigger warnings
655 - A Shared Library: Rewrite and split into subsections.
658 * Fix depcomp's icc mode for ICC 7.1.
659 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
660 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.

688 * Minor documentation fixes.
691 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
692 * Query distutils for `pythondir' and `pythonexecdir', instead of
693 using an hardcoded path. This should allow builds on 64-bit
694 distributions that usually use lib64/ instead of lib/.
695 * AM_PATH_PYTHON will also search for python2.3.
696 * elisp files are now built all at once instead of one by one. Besides
697 incurring a speed-up, this is required to support interdependent elisp files.
699 - `make distcheck' will now work in `_inst/' and `_build' instead
700 of `=inst/' and `=build/'

725 if AM_GNU_GETTEXT([external]) is used.
726 * Correctly uninstall renamed man pages.
727 * Do not strip escaped newline in variables defined in one condition
728 and augmented in another condition.
729 * Fix ansi2knr rules for LIBOBJS sources.
730 * Clean all known Texinfo index files, not only those which appear to
731 be used, because we cannot know wich indexes are used in included files.
732 (PR/375, Debian Bug #168671)
733 * Honor only the first @setfilename seen in a Texinfo file.
734 * Treat "required file X not found" diagnostics as errors (exit status 1).

743 * Add missing `fi' in the .c->.obj rules.
744 * Improve install-sh to work even when names contain spaces or certain
745 (but not all) shell metachars.
746 * Fix the following spurious failures in the test suite:
747 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
748 * Noteworthy manual updates:
749 - Augment the section about BUILT_SOURCES.
750 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
753 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
755 * Aclocal should now recognize macro names containing parentheses, e.g.
756 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
757 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
759 * Install Python files even if they were built. (PR/369)
760 * Have stamp-vti dependent upon configure instead of configure.ac, as the
761 version might not be defined in the latter. (PR/358)
762 * Reorder arguments passed to a couple of commands, so things works
763 when POSIXLY_CORRECT=1.
764 * Fix a regex that can cause Perl to segfault on large input.

767 as in the `Conditional compilation using Automake conditionals' example
769 * Fix spurious test suite failures on IRIX.
770 * Don't report a required variable as undefined if it has been
771 defined conditionally for the "right" conditions.
772 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
773 `make distcheck' fails.
774 * Fix distribution of included Makefile fragment, so we don't create
775 spurious directories in the distribution. (PR/366)
776 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
779 * Autoconf 2.54 is required.
780 * `aclocal' and `automake' will no longer warn about obsolete
781 configure macros. This is done by `autoconf -Wobsolete'.
782 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
783 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
784 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
785 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
786 `configure.ac' for you.
787 * Support for per-program and per-library `_CPPFLAGS'.
788 * New `ctags' target (builds CTAGS files).
789 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
790 (see `automake --help' or the manual for a list of them).
791 * Honor the WARNINGS environment variable.
792 * Omit the call to depcomp when using gcc3: call the compiler directly.

804 * Use Autoconf's --trace interface to inspect configure.ac and get
805 a more accurate view of it.
806 * Add support for extending aclocal's default macro search path
807 using a `dirlist' file within the aclocal directory.
808 * automake --output-dir is deprecated.
809 * The part of the distcheck target that checks whether uninstall actually
810 removes all installed files has been moved in a separate target,
811 distuninstallcheck, so it can be overridden easily.
815 * Support for AM_INIT_GETTEXT([external])
816 * Bug fixes, including:
817 - Fix Automake's own `make install' so it works even if `ln' doesn't.
818 - nobase_ programs and scripts honor --program-transform correctly.

838 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
839 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
842 * Autoconf 2.52 is required.
843 * automake no longer run libtoolize.
844 This is the job of autoreconf (from GNU Autoconf).
845 * `dist' generates all the archive flavors, as did `dist-all'.
846 * `dist-gzip' generates the Gzip tar file only.
847 * Combining Automake Makefile conditionals no longer lead to a combinatorial
848 explosion. Makefile.in's keep a reasonable size.

853 * EXTRA_DIST can contain generated directories.
854 * Support for dot-less extensions in suffix rules.

865 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
866 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
867 (Note that "pkgname" is not "tarname", see the manual for details.)
868 It is also possible to pass a list of global Automake options as
869 first argument to this new form of AM_INIT_AUTOMAKE.
870 * Compiler-based assembler is now called `CCAS'; people expected `AS'
871 to be a real assembler.
872 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
873 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
874 * aclocal and automake are also installed with the version number
875 appended, and some of the install directory names have changed.
