  *) Linux, AIX: Use crypt_r() instead of crypt() because the native
     crypt() is not thread-safe.  The misuse of crypt() led to   
     intermittent failures with Apache basic authentication when crypt 
     passwords were being used.  [Jeff Trawick]

  *) AIX: Global mutexes don't need an intraprocess mutex when SysV
     sems are used for the crossprocess mutex.
     Darwin: The same optimization was applied for Posix sems.
     [Jeff Trawick]

  *) Fix a problem with global mutexes on OS/390 when something other
     than the default mechanism (SysV sem) was used.  The mutexes didn't
     necessarily block out other threads in the same process.
     [Jeff Trawick]

  *) Fixed apr_strfsize formatting of values over 1 gig
     [Matsuzaki Yoshinobu <[e-mail]>]

  *) Renamed --disable-atomics as --disable-optimized-atomics,
     since it doesn't really disable the atomics.  [Aaron Bannert]

  *) Converted apr_pcalloc to a macro  [Brian Pane]

  *) Fixed APR_STATUS_IS_ETIMEDOUT macro.
     [Dagfinn Aarvaag <[e-mail]>]

  *) Add --disable-atomics switch to override our handcoded assembly
     optimizations.  Note that this has no effect if your operating
     system has a userspace atomic interface.  [Justin Erenkrantz]

  *) Remove Linux atomic support since it does not have a usable
     userspace atomic interface.  [Justin Erenkrantz]

  *) Don't require that the DNS can map 127.0.0.1 when checking for
     the presence/usability of getnameinfo().  PR 7642.  [Jeff Trawick]

  *) Remove APR_WANT_SIGNAL from apr_want.h because code must include
     apr_signal.h in order to get consistent definitions. [Roy Fielding]

  *) Don't try to use /dev/zero and mmap on platforms that don't
     support that (such as HP-UX).  PR 8537.  [Justin Erenkrantz]

  *) Reduce the number of apr_sendfile calls on AIX and OS/390 by
     remembering when the kernel tells us the next one will block.
     [Jeff Trawick]

  *) Reduce the number of apr_sendfile calls on FreeBSD by remembering
     when the kernel tells us the next one will block.  [Greg Ames]

  *) To support modules like PHP, which implement their own
     loaded extensions, Darwin needs to place their public
     symbols in the global table. [Marko Karppinen <[e-mail]>,
     Jim Jagielski]

  *) Rename apr_get_groupname to apr_group_name_get.
     [Thom May <[e-mail]>]
     
  *) Allow VPATH builds to properly build dependencies and switch to
     a .deps dependency model to mimic httpd-2.0.  [Justin Erenkrantz]

  *) Tru64: Stop leaving zombies in APR apps like mod_cgid which
     tell APR to ignore SIGCHLD.  
     [Dave Hill <[e-mail]>]

  *) Ensure that the ATOMIC_HASH can not be negative.
     [Joe Orton <[e-mail]>]

  *) Fix a problem with eof reporting with Unix file I/O on 
     unbuffered files.  [Stas Bekman <[e-mail]>]

  *) Rename apr_explode_time to apr_time_exp_tz.
     [Thom May <[e-mail]>]

  *) Rename apr_explode_localtime to apr_time_exp_lt.
     [Thom May <[e-mail]>]

  *) Set precompiler for Solaris atomics when using GNU binutils.
     PR 7876.  [[e-mail] (Marvin Solomon)]

  *) AIX: Fix breakage with 64-bit builds on versions of AIX prior
     to 5L.  PR 7957  [Jeff Trawick]

  *) On socket write functions (apr_sendfile, apr_send, apr_sendv),
     added a select to wait for writability on the socket if the
     previous write was incomplete.  [Jeff Trawick, Brian Pane]

  *) Deprecated the apr_lock.h API. Please see the following files
     for the improved thread and process locking and signaling:
     apr_proc_mutex.h, apr_thread_mutex.h, apr_thread_rwlock.h,
     apr_thread_cond.h, and apr_global_mutex.h.  [Aaron Bannert]

  *) Fix some daylight savings time breakage on (at least) AIX, 
     Solaris, and HP-UX.  [Jeff Trawick]

  *) Added support for Posix semaphores (sem_open, et.al.) for mutex
     locking. We use named semaphores in this implementation. The
     default priority is between pthread and sysvsem.
     [Jim Jagielski]

  *) Get flock-based mutexes to work in apps like Apache.  Use the
     same permissions on flock- and fcntl-based mutexes as Apache
     1.3.  [Jeff Trawick]

  *) Fix apr-config so that it will not attempt to cd to a non-existent
     directory.  [Justin Erenkrantz]

  *) Change the ordering of the apr_lock implementation method to
     better match what's done in Apache 1.3. The ordering is
     now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
     [Jim Jagielski]

  *) Improve detection of the INT64_C macro to prevent problems
     with HP-UX's ANSI C compiler.  PR 8932.  [Justin Erenkrantz]

  *) Make sure gethostbyname() can handle 255.255.255.255 if we
     are to trust it to handle numeric address strings in
     apr_sockaddr_info_get().  This fixes a problem on HP-UX
     which led to an assertion failure at Apache startup when
     using vhosts.  [Jeff Trawick]

  *) Don't mask SIGUSR2 [Jin Hong <[e-mail]>]  

  *) Load libraries if they not MH_BUNDLE, but if they are not, it 
     just attempts to link them as shared libs.
     [Pier Fumagalli <[e-mail]>]

  *) apr_atomic_dec now returns a zero value if the value of 
     the atomic is zero, non-zero otherwise [Ian Holsman]

  *) When opening a file, only create an internal thread mutex
     if APR_XTHREAD is set.  [Brian Pane]

  *) Move the kill_conditions enum in apr_thread_proc.h into the
     APR namespace. kill_after_timeout et al have been renamed
     appropriately (e.g., APR_KILL_AFTER_TIMEOUT).  [Jeff Trawick]

  *) Fix a segfault in apr_thread_rwlock_destroy() on Win32.
     [INOUE Seiichiro <[e-mail]>]
  
  *) configure now checks to see if we can change DNS timeout values
     [Ian Holsman]

  *) Fix a bug in apr_file_seek() on Unix when using buffered
     files.  PR 10003 [Jeff Trawick]

  *) Small table performance optimization: eliminate the
     zero-fill of newly allocated elements when expanding
     a table's size. [Brian Pane]

  *) Allow APR to install its generated libtool(s) via the 
     --with-installbuilddir option (defaults to ${datadir}/build).
     [Justin Erenkrantz]

  *) renames: apr_ansi_time_to_apr_time becomes apr_time_ansi_put
     ap_exploded_time_t becomes apr_time_exp_t
     [Thom May <[e-mail]>]

  *) Add the APR_FILE_NOCLEANUP flag to apr_file_open().
     Adding the flag will prevent the file from being closed 
     when the pool passed in on apr_file_open() is destroyed.
     This feature is useful when using apr_os_file_get|put()
     to manage the apr_os_file_t in apr_file_t (ie, file handle
     caching in the HTTP server) [Bill Stoddard]

  *) Win32: Fix APR_XTHREAD problems in apr_file_read()
     and apr_file_write(). Multiple threads were using the
     same overlapped structure and io event handle created
     in the open call, which could cause unpredictable
     file i/o results. [Bill Stoddard]

  *) Win32: apr_proc_mutex_trylock and apr_proc_mutex_lock were 
     incorrectly returning APR_BUSY if the lock was previously
     held by a thread that exited before releasing the lock 
     (ie, if the process holding the lock segfaults). The MSDN
     doc says when WaitForSingleObject returns WAIT_ABANDONED,
     the calling thread takes ownership of the mutex, so these
     two routines should return APR_SUCCESS in this case, not
     APR_BUSY. [Bill Stoddard]

  *) Added a new m4 function APR_EXPAND_VAR that will iteratively
     interpolate the contents of a variable, such as $sysconfdir,
     for use in a borne script.  [Aaron Bannert]

  *) apr-atomic support for old-sparc's and gas on solaris
     [Dale Ghent <[e-mail]>,  jean-frederic clere, Ian Holsman]

  *) Change apr_proc_detach to take a parameter that can enable/disable
     automatic forking (aka, to "daemonize").
     [Jos Backus <[e-mail]>, Aaron Bannert]

  *) Implement apr_global_lock_foo() on Win32
     [Bill Stoddard]

  *) Fix select() argument call when waiting for IO.  PR 9674.
     [David MacKenzie <[e-mail]>]

  *) Add a new lock API (apr_global_mutex_t) to provide guaranteed
     cross-process AND cross-thread mutual exclusion.  [Aaron Bannert]

  *) Note: We are in the process of deprecating the apr_lock.h API.
     The new and improved lock/synchronization APIs now reside
     in apr_thread_mutex.h, apr_proc_mutex.h, apr_thread_rwlock.h,
     and apr_thread_cond.h.  [Aaron Bannert]

  *) Enable autoconf 2.52{f,g} build support.
     [Blair Zajac <[e-mail]>]

  *) Added new functions for atomic operations. These are experimental
     at the moment, so use in apps is discouraged [Ian Holsman]

  *) Correct serious problems with the Win32 apr_file_dup2 
     and apr_file_open_stdxxx() fns.  [William Rowe]

  *) Begin implementation of the WinCE port.
     [Mladen Turk <[e-mail]>]

  *) Disable SHMEM_MMAP_ZERO on HPUX 11.x where it is not supported.
     Use SHMEM_SHMGET_ANON instead.  [Aaron Bannert]

  *) Fix a few attempts to add to a void * ptr in the Unix shared
     memory support code.  PR #9710  Per Ekman [[e-mail]]

  *) In the Linux apr_sendfile(), fix the types of some parameters 
     to apr_send() and apr_recv().  Breakage was seen in 64-bit mode
     on s/390.  PR #9712  [[e-mail]]

  *) added APR_PROGRAM_ENV and APR_PROGRAM_PATH options for starting
     processes via apr_proc_create() [Greg Stein]

  *) Deprecated apr_pool_free_blocks_num_bytes() [Sander Striker]

  *) Add --enable-pool-debug to make it easier for people to
     enable pool debug mode.  Removed the APR_POOL_DEBUG_VERBOSE
     define that was previously being used. [Sander Striker]
     
  *) Changed the apr_file_dup2() function prototype. It can only
     take and reuse an apr_file_t*, and will no longer create one
     if *new_file == NULL (use apr_file_dup() for that).  [Aaron Bannert]

  *) Implemented name-based shared memory on Unix.  [Aaron Bannert]

  *) Fix spelling mistakes in APRDesign.  
     [Blair Zajac <[e-mail]>]

  *) Ensure that apr_file_mktemp creates the temp file if it isn't there.
     [John Sterling <[e-mail]>]

  *) Make sure to pre-mark anon SysV shared memory segments as
     removed. [Jim Jagielski]

  *) Add --with-efence to allow usage of Electric Fence.
     [Justin Erenkrantz]

  *) Updated the pools debug code.  Check if a pool is still
     valid on the most common apr_pool_xxx functions.
     Fix the way APR_POOL_DEBUG_VERBOSE was using stderr.
     Make the output somewhat nicer in this debug mode. [Sander Striker]

  *) Add new define APR_POOL_DEBUG_VERBOSE which spits out info
     about pool creation/destruction [Ian Holsman]

  *) Fix GMT offset adjustments for platforms that do not have native
     GMT offset adjustments.  [Jon Travis <[e-mail]>]

  *) Add new apr_shm_t API and remove old apr_shmem_t API. The new
     API handles both anonymous and name-based shared memory. Anonymous
     shared memory segments are only usable on systems with process
     inheritance, and so the new API with name-based segments is
     usable on platforms like Win32.  [Aaron Bannert and William Rowe
     with much help from Justin Erenkrantz and Sander Striker]

  *) Add --with-egd to support EGD-compatible entropy gatherers for 
     those platforms without native support.  [Justin Erenkrantz]

  *) apr_lock_create() and apr_proc_mutex_create() now have an
     additional parameter for specifying the lock mechanism.  
     apr_lock_create_np() and apr_proc_mutex_create_np() have been
     removed.  [Jeff Trawick]

  *) Change the prototype of apr_thread_exit() so that the apr_status_t
     is no longer a pointer. It was difficult and sometimes hazardous
     to return a apr_status_t* at times, and this allows us to return
     the APR_* error codes directly.  [Aaron Bannert]

  *) Add apr_sockaddr_equal() for comparing APR sockaddrs.
     [Jeff Trawick]

  *) Win32: apr_sendfile() should return APR_ENOTIMPL if
     oslevel < WINNT. [Bill Stoddard]

  *) Put new pools code in place which allows applications to
     switch off locking on pools operations in case a pool is
     guaranteed to never being used in more than one thread
     at the same time.  We've seen a significant performance
     improvement over the old code. [Sander Striker]

  *) Add apr-config - a shell script to allow third-party programs
     easy access to APR configuration parameters.  [Justin Erenkrantz]

  *) Add find_apr.m4 to allow third-party programs that use APR to
     have a standard m4 macro for detection.  [Greg Stein]

  *) SEGV in apr_table_overlap [Brian Pane]

  *) apr_array_copy speedup by removing the zero-fill [Brian Pane]

  *) Fix build breakage on systems with getaddrinfo(
