- gperftools 2.5, available 12 March 2016.
  See https://github.com/gperftools/gperftools/releases
  * Bryan Chan has contributed s390x support
  * stacktrace capturing via libgcc's _Unwind_Backtrace was implemented
    (for architectures with missing or broken libunwind).
  * "emergency malloc" was implemented. Which unbreaks recursive calls
    to malloc/free from stacktrace capturing functions (such us glib'c
    backtrace() or libunwind on arm). It is enabled by
    --enable-emergency-malloc configure flag or by default on arm when
    --enable-stacktrace-via-backtrace is given. It is another fix for a
    number common issues people had on platforms with missing or broken
    libunwind.
  * C++14 sized-deallocation is now supported (on gcc 5 and recent
    clangs). It is off by default and can be enabled at configure time
    via --enable-sized-delete. On GNU/Linux it can also be enabled at
    run-time by either TCMALLOC_ENABLE_SIZED_DELETE environment variable
    or by defining tcmalloc_sized_delete_enabled function which should
    return 1 to enable it.
  * we've lowered default value of transfer batch size to 512. Previous
    value (bumped up in 2.1) was too high and caused performance
    regression for some users. 512 should still give us performance
    boost for workloads that need higher transfer batch size while not
    penalizing other workloads too much.
  * Brian Silverman's patch finally stopped arming profiling timer
    unless profiling is started.
  * Andrew Morrow has contributed support for obtaining cache size of the
    current thread and softer idling (for use in MongoDB).
  * we've implemented few minor performance improvements, particularly
    on malloc fast-path.
  * issue that caused spurious profiler_unittest.sh failures was fixed.
  * Jonathan Lambrechts contributed improved callgrind format support to
    pprof.
  * Matt Cross contributed better support for debug symbols in separate
    files to pprof.
  * Matt Cross contributed support for printing collapsed stack frame
    from pprof aimed at producing flame graphs.
  * Angus Gratton has contributed documentation fix mentioning that on
    windows only tcmalloc_minimal is supported.
  * Anton Samokhvalov has made tcmalloc use mi_force_{un,}lock on OSX
    instead of pthread_atfork. Which apparently fixes forking
    issues tcmalloc had on OSX.
  * Milton Chiang has contributed support for building 32-bit gperftools
    on arm8.
  * Patrick LoPresti has contributed support for specifying alternative
    profiling signal via CPUPROFILE_TIMER_SIGNAL environment variable.
  * Paolo Bonzini has contributed support configuring filename for
    sending malloc tracing output via TCMALLOC_TRACE_FILE environment
    variable.
  * user spotrh has enabled use of futex on arm.
  * user mitchblank has contributed better declaration for arg-less
    profiler functions.
  * Tom Conerly contributed proper freeing of memory allocated in
    HeapProfileTable::FillOrderedProfile on error paths.
  * user fdeweerdt has contributed curl arguments handling fix in pprof
  * Frederik Mellbin fixed tcmalloc's idea of mangled new and delete
    symbols on windows x64
  * Dair Grant has contributed cacheline alignment for ThreadCache
    objects
  * Fredrik Mellbin has contributed updated windows/config.h for Visual
    Studio 2015 and other windows fixes.
  * we're not linking libpthread to libtcmalloc_minimal anymore. Instead
    libtcmalloc_minimal links to pthread symbols weakly. As a result
    single-threaded programs remain single-threaded when linking to or
    preloading libtcmalloc_minimal.so.
  * Boris Sazonov has contributed mips compilation fix and printf misue
    in pprof.
  * Adhemerval Zanella has contributed alignment fixes for statically
    allocated variables.
  * Jens Rosenboom has contributed fixes for heap-profiler_unittest.sh
  * gshirishfree has contributed better description for GetStats method.
  * cyshi has contributed spinlock pause fix.
  * Chris Mayo has contributed --docdir argument support for configure.
  * Duncan Sands has contributed fix for function aliases.
  * Simon Que contributed better include for malloc_hook_c.h
  * user wmamrak contributed struct timespec fix for Visual Studio 2015.
  * user ssubotin contributed typo in PrintAvailability code.
  * build fix for Visual Studio. 
  * dynamic sized delete is now disabled by default. It turned out that 
    IFUNC relocations are not supporting our advanced use case on all 
    platforms and in all cases.
- Removed the following patches. All have either been incorporated
  upstream or are no longer applicable in current distros.
  * gperftools-fix_docdir.patch

- gperftools 2.4, available 10 Jan 2015.
  Skipped version 2.3, release 7 Dec 2014. 2.3 changes included:
  * ( issue 631 ) fixed debugallocation miscompilation on mmap-less 
    platforms (courtesy of user iamxujian) 
  * ( issue 630 ) reference to wrong PROFILE (vs. correct CPUPROFILE) 
    environment variable was fixed (courtesy of WenSheng He) 
  * pprof now has option to display stack traces in output for heap 
    checker (courtesy of Michael Pasieka) 
  * ( issue 636 ) pprof web command now works on mingw 
  * ( issue 635 ) pprof now handles library paths that contain spaces 
    (courtesy of user mich...@sebesbefut.com) 
  * ( issue 637 ) pprof now has an option to not strip template 
    arguments (patch by jiakai) 
  * ( issue 644 ) possible out-of-bounds access in GetenvBeforeMain 
    was fixed (thanks to user abyss.7) 
  * ( issue 641 ) pprof now has an option --show_addresses (thanks to 
    user yurivict). New option prints instruction address in addition 
    to function name in stack traces 
  * ( issue 646 ) pprof now works around some issues of addr2line 
    reportedly when DWARF v4 format is used (patch by Adam McNeeney) 
  * ( issue 645 ) heap profiler exit message now includes remaining 
    memory allocated info (patch by user yurivict) 
  * pprof code that finds location of /proc/pid/maps in cpu profile 
    files is now fixed (patch by Ricardo M. Correia) 
  * ( issue 654 ) pprof now handles "split text segments" feature of 
    Chromium for Android (patch by simonb) 
  * ( issue 655 ) potential deadlock on windows caused by early call 
    to getenv in malloc initialization code was fixed (bug reported 
    and fix proposed by user zndmitry) 
  * incorrect detection of arm 6zk instruction set support 
    (-mcpu=arm1176jzf-s) was fixed. (Reported by pedronavf on old issue-493) 
  * new cpu profiling mode on Linux is now implemented. It sets up separate 
    profiling timers for separate threads. Which improves accuracy of 
    profiling on Linux a lot. It is off by default. And is enabled if both 
    librt.f is loaded and CPUPROFILE_PER_THREAD_TIMERS environment 
    variable is set. But note that all threads need to be registered 
    via ProfilerRegisterThread. 
  Changes for version 2.4~rc
  * enabled aggressive decommit option by default. It was found to 
    significantly improve memory fragmentation with negligible impact 
    on performance. (Thanks to investigation work performed by Adhemerval 
    Zanella) 
  * added ./configure flags for tcmalloc pagesize and tcmalloc allocation 
    alignment. Larger page sizes have been reported to improve performance 
    occasionally. (Patch by Raphael Moreira Zinsly) 
  * sped-up hot-path of malloc/free. By about 5% on static library and 
    about 10% on shared library. Mainly due to more efficient checking 
    of malloc hooks. 
  * improved accuracy of stacktrace capturing in cpu profiler (due to 
    issue found by Arun Sharma). As part of that issue pprof's handling 
    of cpu profiles was also improved.

- gperftools 2.2, released 3 May 2014.
  * issue 620 (crash on windows when c runtime dll is reloaded) was
    fixed
  * a number of fixes for a number compilers and platforms. Notably
    Visual Studio 2013, recent mingw with c++ threads and some OSX
    fixes.
  * we now have mips and mips64 support! (courtesy of Jovan Zelincevic,
    Jean Lee, user xiaoyur347 and others)
  * we now have aarch64 (aka arm64) support! (contributed by Riku
    Voipio)
  * there's now support for ppc64-le (by Raphael Moreira Zinsly and
    Adhemerval Zanella)
  * there's now some support of uclibc (contributed by user xiaoyur347)
  * google/ headers will now give you deprecation warning. They are
    deprecated since 2.0
  * there's now new api: tc_malloc_skip_new_handler (ported from chromium
    fork)
  * issue-557: added support for dumping heap profile via signal (by
    Jean Lee)
  * issue-567: Petr Hosek contributed SysAllocator support for windows
  * Joonsoo Kim contributed several speedups for central freelist code
  * TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES environment variable now works
  * configure scripts are now using AM_MAINTAINER_MODE. It'll only
    affect folks who modify source from .tar.gz and want automake to
    automatically rebuild Makefile-s. See automake documentation for
    that.
  * issue-586: detect main executable even if PIE is active (based on
    patch by user themastermind1). Notably, it fixes profiler use with
    ruby.
  * there is now support for switching backtrace capturing method at
    runtime (via TCMALLOC_STACKTRACE_METHOD and
    TCMALLOC_STACKTRACE_METHOD_VERBOSE environment variables)
  * there is new backtrace capturing method using -finstrument-functions
    prologues contributed by user xiaoyur347
  * few cases of crashes/deadlocks in profiler were addressed. See
    (famous) issue-66, issue-547 and issue-579.
  * issue-464 (memory corruption in debugalloc's realloc after
    memallign) is now fixed
  * tcmalloc is now able to release memory back to OS on windows
    (issue-489). The code was ported from chromium fork (by a number of
    authors).
  * Together with issue-489 we ported chromium's "aggressive decommit"
    mode. In this mode (settable via malloc extension and via
    environment variable TCMALLOC_AGGRESSIVE_DECOMMIT), free pages are
    returned back to OS immediately.
  * MallocExtension::instance() is now faster (based on patch by
    Adhemerval Zanella)
  * issue-610 (hangs on windows in multibyte locales) is now fixed

    (specified in CPUPROFILESIGNAL)
  * (issue 491) fixed race-ful spinlock wake-ups
  * (issue 496) added some support for fork-ing of process that is using
    tcmalloc
