-* Noteworthy changes in release ?.? (????-??-??) [?]
+* Noteworthy changes in release 2015.09.25 (2015-09-25) [stable]
+
+  The Archive no longer releases an "lzip"-compressed tarball. The only
+  supported format now is "xz". The rationale is that xz so widely supported
+  that it seems pointless to archive two release archives on our servers for no
+  apparent reason.
+
+  AX_PYTHON_DEVEL changed to provide PYTHON_LIBS, not PYTHON_LDFLAGS. This
+  change breaks scripts written with previous versions in mind! The rationale
+  is that -L and -l are LIBS arguments, not LDFLAGS arguments. Returning output
+  in PYTHON_LDFLAGS suggested wrongly that they should be used in LDFLAGS,
+  which can cause the -L and -l arguments to be ignored when they are not in
+  the expected position in the list of command line arguments. This is a
+  problem, for instance, with the command line generated by AC_LINK_IFELSE.
+
+  AX_CXX_COMPILE_STDCXX_11 now supports Cray's crayCC compiler (CCE 8.4).
+
+  AX_PYTHON, AX_PYTHON_EMBED now support Python 3.4.
+
+  AX_LIB_ORACLE_OCI now supports Oracle 12.
+
+  AX_EXT now supports AVX2/AVX512 and other CPU extensions.
+
+  The new macro AX_GNU_AUTOTEST was added. The macro supports multiple
+  test-suites, Makefiles in different locations and many more features.
+
+  AX_CXX_COMPILE_STDCXX_11 now checks for attribute support with C++11 macro.
+  Some compilers pass the other tests while not implementing this part of the
+  C++11 specification. The test used also does not cause warnings with GCC or
+  Clang, and can be used with -Werror.
+
+  The new macro AX_PROG_BISON_VERSION can be used to check for specific
+  versions of bison.
+
+  The new macro AX_PROG_FLEX_VERSION can be used to check for specific
+  versions of flex.
+
+  AX_APPEND_FLAG no longer fails if the given flag contains a ','.
+
+  AX_LUA now supports Lua 5.3.
+
+  AX_BERKELEY_DB_CXX now supports FreeBSD.
+
+  AX_CXX_COMPILE_STDCXX_11 now support HP aCC.
+
+  AX_PYTHON_MODULE and AX_PYTHON_MODULE_VERSION now support Python 3.
+
+  The new macro AX_PYTHON_MODULE_VERSION has been added.
+
+  AX_LIB_POSTGRESQL provides a new output variable POSTGRESQL_LIBS.
+
+  AX_PATH_GENERIC now supports flags that contain spaces.
+
+  AX_BOOST_BASE now supports native Windows header only libraries.
