    Thanks to https://github.com/szabgab/

1.50 Fri Nov 6 20:40 2020
  - Allow get_and_set sub to return an options
    hash passed to the internal set call

1.49 Tue Mar 24 10:15 2020
  - Fix windows compilation and test warnings
    Thanks to hvn@radiatorsoftware.com

1.48 Thu Apr 11 11:30 2019
  - Remove use of // so we should work on 5.8 again
  - Replace -1 with a NOPAGE constant
  - Use 64bit offsets so we support caches > 4G
  - Various valgrind code fixes
    Thanks to oschwald@gmail.com

1.47 Fri Apr 6 11:10 2018
  - Allow custom serializer or compressor options
  - Update bugtracker link to github
    Thanks to toddr@cpan.org

1.46 Fri Jul 14 19:40 2017
  - Fix tests on older perls (thanks stephanloyd9@gmail.com)
  - Use File::Spec for temp dir (thanks fraserbn@gmail.com)
  - Fix mmap_cache_internals.h include guard
  - Fix get_and_set() always returning 0 for DidStore
  - Allow setting permission when creating cache file
  - Tweak leak detection tests
  - Fix last_access/expire_time checks for impending
     1500000000 seconds since epoch

1.45 Thu Mar 14 11:10 2017
  - Deprecate raw_values and compress options, add
     new compressor and serializer options to allow
     different compressors and serializers.
     Initial compressor support: zlib, lz4, snappy
     Initial serializer support: storable, sereal, json
     Thanks to nickt@broadbean.com for initial work

1.44 Wed Jun 1 21:45 2016
  - Set FD_CLOEXEC flag on cache files when opened.
     Particularly useful in Net::Server where
     HUPing a process causes it to exec() itself.
     Unless you undef the cache references, you'll
     leak fd's after each HUP

1.43 Fri Oct 23 14:00 2015
  - Update copyright + version correctly everywhere

1.42 Fri Oct 23 13:30 2015
  - Allow get_and_set callback to return an empty list
     which means "no change". This allows atomic
     "get, and set if not present" type action, but
     without resetting the expiry time on each get.
     This is basically the same as using the read_cb

1.41 Thu Aug 29 15:30 2013
  - Actually reuse deleted slots. Meant that if
     you used ->remove() a lot, we would re-organise
     cache more than needed
  - Include typo and meta patches from dsteinbrunner

1.40 Mon Dec 5  10:30 2011
  - Work around reference holding bug in
     Compress::Zlib

1.39 Mon Jul 18 09:50 2011
  - Remove CImpl and simplify structure into just
     Cache::FastMmap module making all XS calls
     just function calls in Cache::FastMmap
     namespace

1.38 Sun Jul 17 18:30 2011
  - Fix build process that was completely broken
     after moving files around into different
     directories

1.37 Fri Jul 15 16:30 2011
  - Use a lock object with DESTROY method to avoid
     an alarm with a die leaving around a locked
     paged

1.36 Wed Sep 29 13:10 2010
  - Disable wrapping fcntl() lock call in alarm, hurts
     people that use Time::HiRes::alarm() only to try
     and catch buggy deadlock code. Enable with
     catch_deadlocks option

1.35 Fri Feb 19 12:45 2010
  - Fix for returning potential bug that returns old stored
     data. Could occur if you mix deletes
     (thanks Darrell Bishop)

1.34 Fri Jun 19 12:00 2009
  - perldoc fix (thanks Jonathan Yu)

1.33 Thu Jun 18 12:00 2009
  - Update version in META.yml

1.32 Thu Jun 18 11:55 2009
  - Better LiveCaches tracking via DESTROY

1.31 Thu Jun 18 11:40 2009
  - when in raw_values => 0 mode, the write_cb is now
    correctly called with thawed data, rather than the
    raw frozen data
  - empty_on_exit correctly called even when a global
    cache is left at interpreter exit time (required
    Scalar::Util qw(weaken) for object tracking)

1.30 Fri May 8  11:10 2009
  - Fix for Mandriva compiler (thanks Jean-Christian Hassler)

1.29 Fri May 1  17:20 2009
  - Support for Windows (thanks to Ash & kmx.at.volny.cz)
    (https://rt.cpan.org/Public/Bug/Display.html?id=45210)
    (https://rt.cpan.org/Public/Bug/Display.html?id=16501)

1.28 Fri Jun 27 11:05 2008
  - get_and_set() returns new value + didstore boolean
     if called in list context

1.27  Wed Jun 18 17:15 2008
  - Fix non-ansi C code
  - Remove debug flags

1.26  Thu May 22 14:50 2008

      thanks to Sam Vilain

      thanks to Sam Vilain

1.25  Mon Feb 04 13:20 2008
  - Fix multi_set bug and add test
    (http://rt.cpan.org/Ticket/Display.html?id=32895)
  - Test share_file is not a reference
    (http://rt.cpan.org/Ticket/Display.html?id=32252)
  - Fix C variable declaration error
    (http://rt.cpan.org/Ticket/Display.html?id=31223)
  - Fix compile warnings in FreeBSD

  - Thanks to all the people that contributed
     to the above bugs

1.24  Mon Oct 22 13:15 2007
  - Add atomic get_and_remove() method thanks to
      Darrell Bishop

1.23  Wed Oct 17 16:00 2007
  - Fix expire time parsing

1.22  Wed Oct 17 14:05 2007
  - If third parameter to set() is not a references, treat it as
    a specify expiry time. Increases compatiability with
    Cache::Cache API. Helpful for Catalyst framework

1.21  Tue Oct 16 10:40 2007
  - if first parameter to new() is a hash ref, use it as
     the options hash. Helpful for Catalyst framework

1.20  Thu Oct 2 13:40 2007
  - add to documentation about page size and cache file locations
  - fix t/6.t test failure under new Test::More

1.19  Thu Aug 23 09:03 2007
  - bad C declaration crept in again, now in svn

1.18  Thu Aug 22 17:30 2007
  - fix use of $^O not to catch "darwin"
    (http://rt.cpan.org/Ticket/Display.html?id=28330)

1.17  Thu Aug 22 17:14 2007
  - fix declaration in C code that wasn't legal C

1.16  Thu May 8 17:12 2007
  - fix typo in Changes file (1.15 is 2007, not 2006)
  - fix get_keys(2) when undef values in cache
  - fix some leak detection tests

1.15  Thu May 8 17:12 2007
  - catch and rethrow die/exceptions in get_and_set() callbacks
  - avoid undef warnings when using cache_not_found mode
  - use unique tempfile name rather than the same every time
  - add allow_recursive option to allow calls to cache
    from within a read/write callback sub
  - add checks to die if we try and lock a cache twice,
    rather than just causing mysterious errors
  - add unlink_on_exit to automatically delete the share_file
    when the cache exits. default to true if we created
    the share_file, false if we connected to an existing one
  - make empty_on_exit only call empty if the pid of the
    process we're cleaning up in is the same as the pid we
    were created in
  - die in CLONE, making it clear threads aren't supported

1.14  Thu Oct 20 11:45 2006
  - alter calc_expunge to allow more efficient alternate
    implementation cases

1.13  Thu Oct 20 11:15 2006
  - mention UNIX/Win32 compatiability in docs
    (http://rt.cpan.org/Ticket/Display.html?id=16501)
  - detect page corruption better and croak rather than segfault
    (http://rt.cpan.org/Ticket/Display.html?id=17335)
  - when running in raw_values => 0 mode, always store
    reference to data. Storable doesn't like freeze(SCALAR)
    (http://rt.cpan.org/Ticket/Display.html?id=16762)
  - Handle edge case of slot count increase when page
    already nearly full possibly causing corruption
    (can only happen if ->purge() called at just the wrong time)

1.12  Thu Oct 19 09:50 2006
  - allow writing into a deleted slot

1.11  Web Oct 18 15:10 2006
  - allow setting default slot count via start_slots argument

1.10  Web Oct 18 14:50 2006
  - fc_lock() would segfault if no slots were available.
    Doesn't happen in normal usage, but can happen if
    cache behaviour altered by alternate code

1.09  Thu Feb  7 15:50 2005
  - add get_and_set() routine to allow atomic reading and
    writing of a cache value (thanks to Sreeji Das)
