     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)
-
-  Bug fixes:
-  - Fix a severe virtual memory leak.  This regression was first released in
-    4.3.0.  (@interwq, @jasone)
-  - Refactor atomic and prng APIs to restore support for 32-bit platforms that
-    use pre-C11 toolchains, e.g. FreeBSD's mips.  (@jasone)
-
-* 4.3.0 (November 4, 2016)
-
-  This is the first release that passes the test suite for multiple Windows
-  configurations, thanks in large part to @glandium setting up continuous
-  integration via AppVeyor (and Travis CI for Linux and OS X).
-
-  New features:
-  - Add "J" (JSON) support to malloc_stats_print().  (@jasone)
-  - Add Cray compiler support.  (@ronawho)
-
-  Optimizations:
-  - Add/use adaptive spinning for bootstrapping and radix tree node
-    initialization.  (@jasone)
-
-  Bug fixes:
-  - Fix large allocation to search starting in the optimal size class heap,
-    which can substantially reduce virtual memory churn and fragmentation.  This
-    regression was first released in 4.0.0.  (@mjp41, @jasone)
-  - Fix stats.arenas.<i>.nthreads accounting.  (@interwq)
-  - Fix and simplify decay-based purging.  (@jasone)
-  - Make DSS (sbrk(2)-related) operations lockless, which resolves potential
-    deadlocks during thread exit.  (@jasone)
-  - Fix over-sized allocation of radix tree leaf nodes.  (@mjp41, @ogaun,
-    @jasone)
-  - Fix over-sized allocation of arena_t (plus associated stats) data
-    structures.  (@jasone, @interwq)
-  - Fix EXTRA_CFLAGS to not affect configuration.  (@jasone)
-  - Fix a Valgrind integration bug.  (@ronawho)
-  - Disallow 0x5a junk filling when running in Valgrind.  (@jasone)
-  - Fix a file descriptor leak on Linux.  This regression was first released in
-    4.2.0.  (@vsarunas, @jasone)
-  - Fix static linking of jemalloc with glibc.  (@djwatson)
-  - Use syscall(2) rather than {open,read,close}(2) during boot on Linux.  This
-    works around other libraries' system call wrappers performing reentrant
-    allocation.  (@kspinka, @Whissi, @jasone)
-  - Fix OS X default zone replacement to work with OS X 10.12.  (@glandium,
-    @jasone)
-  - Fix cached memory management to avoid needless commit/decommit operations
-    during purging, which resolves permanent virtual memory map fragmentation
-    issues on Windows.  (@mjp41, @jasone)
-  - Fix TSD fetches to avoid (recursive) allocation.  This is relevant to
-    non-TLS and Windows configurations.  (@jasone)
-  - Fix malloc_conf overriding to work on Windows.  (@jasone)
-  - Forcibly disable lazy-lock on Windows (was forcibly *enabled*).  (@jasone)
-
-* 4.2.1 (June 8, 2016)
-
-  Bug fixes:
-  - Fix bootstrapping issues for configurations that require allocation during
-    tsd initialization (e.g. --disable-tls).  (@cferris1000, @jasone)
-  - Fix gettimeofday() version of nstime_update().  (@ronawho)
-  - Fix Valgrind regressions in calloc() and chunk_alloc_wrapper().  (@ronawho)
-  - Fix potential VM map fragmentation regression.  (@jasone)
-  - Fix opt_zero-triggered in-place huge reallocation zeroing.  (@jasone)
-  - Fix heap profiling context leaks in reallocation edge cases.  (@jasone)
-
-* 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)
-
-* 4.1.1 (May 3, 2016)
-
-  This bugfix release resolves a variety of mostly minor issues, though the
-  bitmap fix is critical for 64-bit Windows.
-
-  Bug fixes:
-  - Fix the linear scan version of bitmap_sfu() to shift by the proper amount
-    even when sizeof(long) is not the same as sizeof(void *), as on 64-bit
-    Windows.  (@jasone)
-  - Fix hashing functions to avoid unaligned memory accesses (and resulting
-    crashes).  This is relevant at least to some ARM-based platforms.
-    (@rkmisra)
-  - Fix fork()-related lock rank ordering reversals.  These reversals were
-    unlikely to cause deadlocks in practice except when heap profiling was
-    enabled and active.  (@jasone)
-  - Fix various chunk leaks in OOM code paths.  (@jasone)
-  - Fix malloc_stats_print() to print opt.narenas correctly.  (@jasone)
-  - Fix MSVC-specific build/test issues.  (@rustyx, @yuslepukhin)
-  - Fix a variety of test failures that were due to test fragility rather than
-    core bugs.  (@jasone)
-
-* 4.1.0 (February 28, 2016)
-
-  This release is primarily about optimizations, but it also incorporates a lot
-  of portability-motivated refactoring and enhancements.  Many people worked on
-  this release, to an extent that even with the omission here of minor changes
-  (see git revision history), and of the people who reported and diagnosed
-  issues, so much of the work was contributed that starting with this release,
-  changes are annotated with author credits to help reflect the collaborative
-  effort involved.
-
-  New features:
-  - Implement decay-based unused dirty page purging, a major optimization with
-    mallctl API impact.  This is an alternative to the existing ratio-based
-    unused dirty page purging, and is intended to eventually become the sole
-    purging mechanism.  New mallctls:
-    + opt.purge
-    + opt.decay_time
-    + arena.<i>.decay
-    + arena.<i>.decay_time
-    + arenas.decay_time
-    + stats.arenas.<i>.decay_time
-    (@jasone, @cevans87)
-  - Add --with-malloc-conf, which makes it possible to embed a default
-    options string during configuration.  This was motivated by the desire to
-    specify --with-malloc-conf=purge:decay , since the default must remain
-    purge:ratio until the 5.0.0 release.  (@jasone)
-  - Add MS Visual Studio 2015 support.  (@rustyx, @yuslepukhin)
-  - Make *allocx() size class overflow behavior defined.  The maximum
-    size class is now less than PTRDIFF_MAX to protect applications against
-    numerical overflow, and all allocation functions are guaranteed to indicate
-    errors rather than potentially crashing if the request size exceeds the
-    maximum size class.  (@jasone)
-  - jeprof:
-    + Add raw heap profile support.  (@jasone)
-    + Add --retain and --exclude for backtrace symbol filtering.  (@jasone)
-
-  Optimizations:
-  - Optimize the fast path to combine various bootstrapping and configuration
-    checks and execute more streamlined code in the common case.  (@interwq)
-  - Use linear scan for small bitmaps (used for small object tracking).  In
-    addition to speeding up bitmap operations on 64-bit systems, this reduces
-    allocator metadata overhead by approximately 0.2%.  (@djwatson)
-  - Separate arena_avail trees, which substantially speeds up run tree
-    operations.  (@djwatson)
-  - Use memoization (boot-time-computed table) for run quantization.  Separate
-    arena_avail trees reduced the importance of this optimization.  (@jasone)
-  - Attempt mmap-based in-place huge reallocation.  This can dramatically speed
-    up incremental huge reallocation.  (@jasone)
-
-  Incompatible changes:
-  - Make opt.narenas unsigned rather than size_t.  (@jasone)
-
-  Bug fixes:
-  - Fix stats.cactive accounting regression.  (@rustyx, @jasone)
-  - Handle unaligned keys in hash().  This caused problems for some ARM systems.
-    (@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.  (@cferris1000, @jasone)
-  - Fix run quantization.  In practice this bug had no impact unless
-    applications requested memory with alignment exceeding one page.
-    (@jasone, @djwatson)
-  - Fix LinuxThreads-specific bootstrapping deadlock.  (Cosmin Paraschiv)
-  - jeprof:
-    + Don't discard curl options if timeout is not defined.  (@djwatson)
-    + Detect failed profile fetches.  (@djwatson)
-  - Fix stats.arenas.<i>.{dss,lg_dirty_mult,decay_time,pactive,pdirty} for
-    --disable-stats case.  (@jasone)
-
-* 4.0.4 (October 24, 2015)
-
-  This bugfix release fixes another xallocx() regression.  No other regressions
-  have come to light in over a month, so this is likely a good starting point
-  for people who prefer to wait for "dot one" releases with all the major issues
-  shaken out.
-
-  Bug fixes:
-  - Fix xallocx(..., MALLOCX_ZERO to zero the last full trailing page of large
-    allocations that have been randomly assigned an offset of 0 when
-    --enable-cache-oblivious configure option is enabled.
-
 * 4.0.3 (September 24, 2015)
 
   This bugfix release continues the trend of xallocx() and heap profiling fixes.

-How to build jemalloc for Windows
-=================================
-
-1. Install Cygwin with at least the following packages:
-   * autoconf
-   * autogen
-   * gawk
-   * grep
-   * sed
-
-2. Install Visual Studio 2015 with Visual C++
-
-3. Add Cygwin\bin to the PATH environment variable
-
-4. Open "VS2015 x86 Native Tools Command Prompt"
-   (note: x86/x64 doesn't matter at this point)
-
-5. Generate header files:
-   sh -c "CC=cl ./autogen.sh"
-
-6. Now the project can be opened and built in Visual Studio:
-   msvc\jemalloc_vc2015.sln
