- Update to version 0.12.3:
Bugfixes
* Automatic image offset detection (for images using a custom
header) did not work correctly if the header contained a
string that would be identified as the start of a v1 section
header (these were only used before dwarfs-0.3.0).
If there was either "DWARFS\x02\x00" or "DWARFS\x02\x01" in
the header, offset detection would fail. The check has been
modified to peek further into the data and ensure this really
is a v1 section header, and also checking if the next section
header position can be derived from the length field.
It is still possible to construct a file system image where
offset detection will ultimately fail, but it is much less
likely with the change.
- Changes in version 0.12.2:
Bugfixes
*The dwarfs-0.12.0 release introduced a performance regression
where FLAC compression took more than twice as long as in the
previous releases. This has been fixed. FLAC decompression was
unaffected.

- Update to version 0.12.1:
Features
* Added --memory-limit=auto to mkdwarfs to use a more reasonable
(hopefully) default for the block queue. The old default of
1 GiB was quite arbitrary and definitely not suitable for
low-end systems. The new auto default will determine the limit
based on the number of workers (which in turn is based on the
number of CPUs), the block size, and the amount of physical
memory of the system.
* Replaced vector_byte_buffer with malloc_byte_buffer, which is
internally based around a simple buffer that doesn't incur the
cost of initializing each element like std::vector. Especially
for large blocks which are known to be overwritten immediately,
this can save a few CPU cycles.
- Changes in version 0.12.0:
* New Licensing Conditions: Instead of being all GPL-3.0 like all
the previous releases, this release changes the license of a
large fraction of the DwarFS code to MIT. All tools and
libraries that only read DwarFS images are now MIT-licensed.
Everything else (e.g. mkdwarfs) is still GPL-3.0 for the time
being.
Bugfixes
* Changes for compatibility with Boost.Process v2.
Features
* Re-licensed all libraries required for reading DwarFS images
under the MIT license. The source of all tools that just read
DwarFS images (i.e. everything except for mkdwarfs) are also
under the MIT license now. Everything else is still GPL-3.0.
gh#mhx/dwarfs#255
* New hotness categorizer in mkdwarfs that allows a list of "hot"
files to be stored in distinct file system blocks.
* New explicit ordering mode in mkdwarfs that allows files to be
ordered accoring to the order in a given list file.
* dwarfs now shows the version of the FUSE library used.
* New dwarfs options preload_all and preload_category to populate
the block cache immediately after mounting.
* New dwarfs option analysis_file that can be used for profiling
and as input to mkdwarfs new hotness categorizer and explicit
ordering mode.
* New dwarfs option block_allocator that allows the user to
switch from a malloc-based block allocator to an mmap-based
one. This can help with returning memory back to the system if
the blocks are evicted from the cache.
