5.0.0 was released at last. Relative to xz-utils in testing, it
brings the following major changes:
- Any preset level (-0 ... -9) specified after a custom filter
chain option (e.g. --lzma2) will override the custom filter chain.
In testing, any preset options after a custom filter chain option
is completely ignored.
- As mentioned before, the compression settings associated with the
preset levels -0 ... -9 have been changed. --extreme was changed a
little, too. It is now less likely to make compression worse, but
with some files the new --extreme may compress slightly worse than
the old --extreme.
- --list is looks ugly in Squeeze on locales that use space as
a thousands separator.
- 5.0.0 allows LZMA_FINISH in addition to LZMA_RUN for Index
encoding and decoding. The API documentation explains that LZMA_RUN
is better if support for < 5.0.0 is needed. This is an advanced API,
not used by any current Debian packages aside from xz-utils itself.
- Major manual page updates and other documentation updates.
The sources are at:
git://git.debian.org/collab-maint/xz.git experimental
The xz-utils package in experimental demonstrates the changes. Most
of these changes have been in experimental for a while, and while they
are not huge, they are still nice to have. Would it be okay to upload
to unstable, perhaps with some extended age-days?
Thanks for your work to bring about a high quality Squeeze,
Jonathan
