XZ Utils Release Notes
|
||||
======================
|
||||
|
||||
5.2.3 (2016-12-30)
|
||||
|
||||
* xz:
|
||||
|
||||
- Always close a file before trying to delete it to avoid
|
||||
problems on some operating system and file system combinations.
|
||||
|
||||
- Fixed copying of file timestamps on Windows.
|
||||
|
||||
- Added experimental (disabled by default) sandbox support using
|
||||
Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL.
|
||||
|
||||
* C99/C11 conformance fixes to liblzma. The issues affected at least
|
||||
some builds using link-time optimizations.
|
||||
|
||||
* Fixed bugs in the rarely-used function lzma_index_dup().
|
||||
|
||||
* Use of external SHA-256 code is now disabled by default.
|
||||
It can still be enabled by passing --enable-external-sha256
|
||||
to configure. The reasons to disable it by default (see INSTALL
|
||||
for more details):
|
||||
|
||||
- Some OS-specific SHA-256 implementations conflict with
|
||||
OpenSSL and cause problems in programs that link against both
|
||||
liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0
|
||||
are affected.
|
||||
|
||||
- The internal SHA-256 is faster than the SHA-256 code in
|
||||
some operating systems.
|
||||
|
||||
* Changed CPU core count detection to use sched_getaffinity() on
|
||||
GNU/Linux and GNU/kFreeBSD.
|
||||
|
||||
* Fixes to the build-system and xz to make xz buildable even when
|
||||
encoders, decoders, or threading have been disabled from libilzma
|
||||
using configure options. These fixes added two new #defines to
|
||||
config.h: HAVE_ENCODERS and HAVE_DECODERS.
|
||||
|
||||
|
||||
5.2.2 (2015-09-29)
|
||||
|
||||
* Fixed bugs in QNX-specific code.
