https://github.com/jemalloc/jemalloc
* 4.4.0 (December 3, 2016)
New features:
- Add configure support for *-*-linux-android. (@cferris1000, @jasone)
- Add the --disable-syscall configure option, for use on systems that place
security-motivated limitations on syscall(2). (@jasone)
- Add support for Debian GNU/kFreeBSD. (@thesam)
Optimizations:
- Add extent serial numbers and use them where appropriate as a sort key that
is higher priority than address, so that the allocation policy prefers older
extents. This tends to improve locality (decrease fragmentation) when
memory grows downward. (@jasone)
- Refactor madvise(2) configuration so that MADV_FREE is detected and utilized
on Linux 4.5 and newer. (@jasone)
- Mark partially purged arena chunks as non-huge-page. This improves
interaction with Linux's transparent huge page functionality. (@jasone)
Bug fixes:
- Fix size class computations for edge conditions involving extremely large
allocations. This regression was first released in 4.0.0. (@jasone,
@ingvarha)
- Remove overly restrictive assertions related to the cactive statistic. This
regression was first released in 4.1.0. (@jasone)
- Implement a more reliable detection scheme for os_unfair_lock on macOS.
(@jszakmeister)
* 4.3.1 (November 7, 2016)
