* 4.2.0 (May 12, 2016)
New features:
- Add the arena.<i>.reset mallctl, which makes it possible to discard all of
an arena's allocations in a single operation. (@jasone@)
- Add the stats.retained and stats.arenas.<i>.retained statistics. (@jasone)
- Add the --with-version configure option. (@jasone)
- Support --with-lg-page values larger than actual page size. (@jasone)
Optimizations:
- Use pairing heaps rather than red-black trees for various hot data
structures. (@djwatson, @jasone)
- Streamline fast paths of rtree operations. (@jasone)
- Optimize the fast paths of calloc() and [m,d,sd]allocx(). (@jasone)
- Decommit unused virtual memory if the OS does not overcommit. (@jasone)
- Specify MAP_NORESERVE on Linux if [heuristic] overcommit is active, in order
to avoid unfortunate interactions during fork(2). (@jasone)
Bug fixes:
- Fix chunk accounting related to triggering gdump profiles. (@jasone)
- Link against librt for clock_gettime(2) if glibc < 2.17. (@jasone)
- Scale leak report summary according to sampling probability. (@jasone)

- Fix MSVC-specific build/test issues. (@rustyx, yuslepukhin)
- Fix MSVC-specific build/test issues. (@rustyx, @yuslepukhin)

core bugs. (@jasone)

Bug fixes:
- Fix stats.cactive accounting regression. (@rustyx, @jasone)
- Handle unaligned keys in hash(). This caused problems for some ARM systems.
(@jasone, Christopher Ferris)
(@jasone, @cferris1000)
- Refactor arenas array. In addition to fixing a fork-related deadlock, this
makes arena lookups faster and simpler. (@jasone)
- Move retained memory allocation out of the default chunk allocation
function, to a location that gets executed even if the application installs
a custom chunk allocation function. This resolves a virtual memory leak.
(@buchgr)
- Fix a potential tsd cleanup leak. (Christopher Ferris, @jasone)
- Fix a potential tsd cleanup leak. (@cferris1000, @jasone)
- Fix run quantization. In practice this bug had no impact unless
applications requested memory with alignment exceeding one page.

will cause files to be installed into /usr/local/include, /usr/local/lib,
and /usr/local/man.
--with-version=<major>.<minor>.<bugfix>-<nrev>-g<gid>
Use the specified version string rather than trying to generate one (if in
a git repository) or use existing the VERSION file (if present).
--with-rpath=<colon-separated-rpath>
Embed one or more library paths, so that libjemalloc can find the libraries
it is linked to. This works only on ELF-based systems.
