0.5.24:

This patch release explicitly requests definition of AT_FDCWD via definition
of _POSIX_C_SOURCE in translation units that refer to it.

0.5.23:

This patch releases fixes a couple of minor issues in slibtool's own build
system.

build system: all-shared front-end variant: fix ordering of -l$(PACKAGE).
build system: all-shared binary: added missing build-dep on $(SHARED_SOLINK).

0.5.22:

This patch release explicitly requests the openat() interface via definition
of _POSIX_C_SOURCE in translation units that need it.

0.5.21:

This patch release follows important enhancements in slibtool's library
interfaces and API contract. In particular, slibtool now no longer uses
streams, but rather pure file descriptors. In addition, i/o operations
now robustly handle interruption by signals, and thus do not depend on
the underlying system calls being restartable. Last but not least,
slibtool now installs a pkgconfig configuration file when applicable.

- argv.h: output usage and errors using [argv_]dprintf rather than fprint.
- argv.h: argv_get(): be consistent between forward decl. and impl.
- argv.h: move definition of struct argv_meta_impl to the implementation block.
- internals: added slbt_mapped_readline().
- internals: added slbt_map_file(), slbt_unmap_file().
- internals: added slbt_dprintf(), a signal-resilient dprintf implementation.
- driver: argv usage and error output: use the signal-resilient slbt_dprintf().
- driver: support alternate fd's for input/output/error/log.
- driver: slbt_init_host_params(): propagate failure of <compiler> -dumpmachine.
- driver: slbt_init_host_params(): do not set fnative when !fdumpmachine.
- driver: struct slbt_fd_ctx: added .fdcwd and .fddst.
- library: invocations of openat() now use the context's fdcwd.
- project: added initial pkgconfig support.

0.5.20:

This patch release includes several important bug fixes pertaining to both
the link and compile mode, as well as the addition of a compatible --features
output.

- driver: added slbt_output_features(), providing compatible --features output.
- driver: compatibility: have -{shared|static} imply -disable-{static|shared}.
- link mode: properly handle the combination of -release and -version-info.
- link mode: slbt_exec_link_create_dep_file(): record top-level -L arguments.
- link mode: --disable-{shared|static}: use differently-named placeholders.

0.5.19:

This patch release includes several improvements in the driver logic,
as well as one important fix to the compile mode logic.

- driver: support -export-dynamic.
- driver: allow flavor-based use of native tools (ar,ranlib,etc.)
- driver: slbt_init_host_params(): improve native target detection logic.
- driver: -shrext support: only use the extension portion of the extension.
- compile mode: gnu libtool compatibility: do not add -c to compiler arguments.

0.5.18:

This patch release includes several important fixes to the link mode
and driver logic. In addition, it adds mdso support to midipix targets,
as well as updates slibtool's own build system.

- link mode: re-implemented slbt_exec_link_finalize_argument_vector().
- link mode: import library generation: added mdso support.
- link mode: use -fpic objects with -disable-static.
- driver: added --mdso and --implib support.
- driver: added initial -dlpreopen support.
- driver: support -thread-safe more elegantly.
- driver: properly handle -thread-safe (no-op, compatibility).

0.5.17:

This patch release fixes a subtle bug in the newly added support for
packages that depend on the reordering of linker arguments.

0.5.16:

This patch release fixes a subtle bug in slibtool-shared's
generation of dependency lists when creating convenience
library archives. Beginning with this release, the mesa
package can be built with slibtool in its entirety.

- slibtool-shared: properly handle .la arguments when creating an archive.
- slbt_exec_link_create_dep_file(): properly initialize and track fdeps.

0.5.15:

This patch release provides seamless support for the building of
packages which rely on the ordering of linker arguments. With
slibtool, reordering takes place only when deemed necessary.

- link mode: support packages that rely on argument reordering.
- error trace: remove and fix inadvertent calls to strerror(3).

0.5.14:

This patch release provides several fixes at the driver level, as well as
several improvements to slibtool's own internals. Addition of extended
variable support to slibtool's ./configure now makes it fully compatible
with (distro) build systems that pass those variable to ./configure by
default.

- link mode: fix fdepfile construction when determining dynlib dependency.
- link mode: static archives: always have ar(1) act as ranlib(1).
- driver: refine handling of --target.
- build system: added extended dir variables.

0.5.13:

This patch release ensures successful installation of a shared library with
which no accompanying static archive was created. The release also includes
two improvements in slibtool's own build system.

- link mode: create an archive /dev/null symlink placeholder as needed.
- PE soname support: added the designated LDFLAGS_SONAME variable.
- build system: configure: pass --sysroot to the linker as a compiler argument.

0.5.12:

This patch release includes a variety of fixes and improvements in slibtool's
functionality, as well as several enhancements to slibtool's own build system.

- driver: added support for -dlopen (currently a no-op).
- error trace: improved and extended the initial interface.
- error trace: added descriptive error strings for custom errors.
- link mode: properly determine whether -L and -ldeplib are needed.
- link mode: do not respect -disable-static without -rpath.
- link mode: respect -disable-static.
- link mode: properly handle indirect dependencies of .a archives.
- link mode: confirm need for archive import; limit .a deps to external deps.
- compile mode: respect -disable-static and -disable-shared.
- install mode: respect -disable-static.
- legacy wrappers: implemented compatible library and objects wrappers.
- build system: added support for cygwin's, mingw's, and msys's semantics.

0.5.11:

This patch release provides -portbld- support for systems that still need
it, as well as an initial implementation of the --uninstall mode. In addition,
this release includes a few important bug fixes, as well as adds --source-dir
support to slibtool's own build system.

- driver: accommodate hosts that occasionally use '-portbld-' in their triple.
- link mode: properly handle -all-static when creating an executable image.
- link mode: add -L.libs for current-directory .la input arguments.
- uninstall mode: initial implementation.
- build system: support setting an external folder as the source directory.

0.5.10:

This patch release fixes the following subtle link-mode bugs:

- link mode: archive creation: .la-associated objects are always under .libs/.
- link mode: soname: properly handle -module when output begins with dso prefix.

0.5.9:

This patch release enhances support of indirect dependencies, as well
the handling of direct invocation of executables (as opposed to passing
an executable to gdb or similar as an argument).

- execute mode: properly handle direct program invocation.
- link mode: account for directory depth when generating .deps for .la wrapper.
- link mode: properly handle sub-directories in indirect .la wrapper dependency.
- link mode: properly handle dependency information in current-dir .la wrappers.

as well as several improvements in slibtool's own build system.

- link mode: always create the .libs directory.
- output: flush stdout upon return from output functions.
- build system: remove generic dependency of object files on version.tag.
- build system: moved core definition files to a designated folder.
- build system: PE targets: handle subsystem setting in pe.mk.
- build system: added --avoid-version support.

0.5.3:

This patch release includes a few minor fixes and several improvements, all
related to slibtool's own build system.

- build system: app.tag: avoid unconditional step execution.
- build system: configure: added --strict, --ccstrict, --ldstrict support.
- build system: Makefile: added the .conf convenience target.
- build system: Makefile: added the .display_cc convenience target.
- build system: Makefile: added the -display_cflags convenience target.
- build system: Makefile: added custom header installation support.

0.5.2:

This patch release includes several fixes of bugs that were discovered while
testing slibtool as the primary libtool in a pkgsrc comprehensive build. In
addition, the release includes several improvements to slibtool's own build
system.

- link mode: legabits: generate a perfectly compatible wrapper.
- install mode: legabits: install a perfectly compatible wrapper.
- project: by default, slibtool is now an application-only package.

0.5.1:

This patch release includes several small fixes, as well as the addition of
an optional (opt-in at runtime) yet important compatibility feature, namely
the installation of .la wrappers. Changes in this release include:

- driver: added --legabits support.
- install mode: optional installation of .la wrappers.
- project: added compatibility symlinks (clibtool, clibtool-[shared|static])
- build system: removed the endian.h test.
- build system: proper use of any-os.mk.

0.5.0:

This is the first tagged release of slibtool. It is the result of two months of
intensive development, and follows rigorous testing on several systems. As of
this initial release, slibtool is known to successfully build an entire Exherbo
Linux system from source, build the midipix cross compilation toolchain from
source, and likewise build many other packages.

Support for the ELF/default host flavor is complete, and does not appear to have
any errors. Support for the PE/midipix flavor is also complete, and includes not
only static archives and shared libraries, but also import libraries with
version support. Support for the Darwin host flavor already exists too, yet it
is currently semantically incorrect, and so will be fixed in the next release.
