NEWS - list of user-visible changes between releases of GNU Libtool

New in 1.5.24: 2007-06-17; CVS version 1.5.23c, Libtool team:
* Initial support for Interix newer than version 3.
* Use getconf ARG_MAX to find the max command line length.
* Bug Fixes.

New in 1.5.23b: 2007-02-17; CVS version 1.5.23a, Libtool team:
* New link flag `-static-libtool-libs' to provide the semantics that
  `-static' had between 1.5 and before 1.5.22.
* Initial support for RDOS.
* Fix regression on DragonFly that disabled library hardcoding.
* Fix regression on OpenBSD, NetBSD, DragonFly, and other systems
  with hardcode_direct=yes that wrongly removed paths to uninstalled
  libraries during link mode.
* Let libltdl know that FreeBSD and DragonFly dlopen causes dependent
  modules to be loaded.  This fixes excessive load times for modules
  with large library dependency graphs.
* Fix error with -version-info on systems with version_type=none, such
  as BeOS.
* Initial support for the Sun compiler suite on GNU/Linux.
* Improved support for GNU/kFreeBSD and GNU/NetBSD.
* Search paths with GCC on multilib systems like x86_64 have been fixed.
* The libtool --tag argument which has been supported since version 1.5
  is documented now.
* Fix regression in libltdl symbol exports on Cygwin. Side effect:
  LT_GLOBAL_DATA and LT_SCOPE are now explicitly defined as
  declspec(dllexport), bypassing auto-export logic on Cygwin.
  This tracks existing behavior on MinGW.
* Bug Fixes.

New in 1.5.22: 2005-12-18; CVS version 1.5.21a, Libtool team:
* Fix 1.5 regression that caused linking a program `-static' to also
  link statically against installed libtool libraries, contrary to
  documented (and actual 1.4.x) behavior.
* Fix file ownership for BSD `ranlib'.
* Initial support for Beos/C++.
* Fixed detection of link_static_flag, and self-dlopening.
* Fixed setting of shlibpath variables (LD_LIBRARY_PATH and similar)
  and order of link search paths for creating and testing of uninstalled
  libraries.
* Fix silent failure of `libtoolize --ltdl' if libltdl files not present.
* Fixed command line settings for non-GCC compilers, Solaris/64bit.
* Support for Interix 3 (Windows SFU).
* If non-pic objects were not compiled, and libtool is called in link
  mode, libtool no longer silently creates an empty archive, but rather
  falls back to pic objects.
* Fix potential denial of service by malicious other users for tmpdir
  directory creation at relink time.
* Bug Fixes, among others for AIX, Cygwin, Darwin, FreeBSD, HPUX, MinGW,
  OpenBSD, UnixWare.

New in 1.5.20: 2005-08-31; CVS version 1.5.19a, Libtool team:
* Fix long-standing Solaris CC limitation failing with -no-undefined.

* Work around breakage on Tru64 due to shell bugs.
* Fix regression with spurious object name conflicts against installed
  static libraries which were erronously treated as convenience libraries.
* Fix building of packages on cygwin managed mounts.
* Bug Fixes.

New in 1.5.18: 2005-05-16; CVS version 1.5.17a, Libtool team:
* Fix regression in 1.5.16 to not install libltdl data files from
  `libtoolize --ltdl'ed software packages.
* Bug Fixes.

New in 1.5.16: 2005-04-24; CVS version 1.5.15a, Libtool team:
* Allow shell special characters like `$' in source file names, but not
  in object names, to enhance GCJ support.
* Detection of compiler wrappers like distcc/ccache and $host_alias prefix.
* More robust tests for PIC flag, `-c -o', in presence of warnings.
* Bug Fixes, among others for convenience archives regression on Solaris
  and timestamp-preserving `libtoolize --copy --ltdl'.

New in 1.5.14: 2005-02-12; CVS version 1.5.13a, Libtool team:
* Make -pthread work when building executabless too.

* Fix for a buffer overrun in the opendir/readdir replacement code.
  This code was used by older versions of MinGW only.
* Some compiler/linker flags commonly used to select ABI features are allowed
  through in link mode.  This fixes some 64bit build failures and Darwin's
  -framework.
* Handling of archives that have multiple members with the same name on Darwin.
