+Changes with APR 0.9.19
+
+  *) SECURITY: CVE-2009-2412 (cve.mitre.org)
+     Fix overflow in pools and rmm, where size alignment was taking place.
+     [Matt Lewis <mattlewis@google.com>, Sander Striker, William Rowe]
+
+  *) Improve platform detection by updating config.guess and config.sub.
+     [Rainer Jung]
+
+Changes with APR 0.9.18
+
+  *) z/OS: return standard apr_status_t codes from apr_dso_load()
+     and apr_dso_sym().  [David Jones <oscaremma gmail.com>]
+
+  *) Fix apr_tokenize_to_argv parsing.  PR 46128
+     [Edward Rudd <eddie omegaware.com>]
+
+Changes with APR 0.9.17
+
+  *) Fix DSO-related crash on z/OS caused by incorrect memory
+     allocation.  [David Jones <oscaremma gmail.com>]
+
+  *) Define apr_ino_t in such a way that it doesn't change definition
+     based on the library consumer's -D'efines to the filesystem.
+     [Lucian Adrian Grijincu <lucian.grijincu gmail.com>]
+
+  *) Cause apr_file_dup2() on Win32 to update the MSVCRT psuedo-stdio
+     handles for fd-based and FILE * based I/O.  [William Rowe]
+
+  *) Revert Win32 to the 0.9.14 behavior of apr_proc_create() for any 
+     of the three stdio streams which are not initialized, through either
+     apr_procattr_io_set() or apr_procattr_child_XXX_set(), when given a
+     procattr_t with one or two streams which were initialized through
+     apr_procattr_child_XXX_set().  Once again, these do not inherit the 
+     parent process stdio stream to WIN32 child processes (passing 
+     INVALID_HANDLE_VALUE instead) as on Unix.  Note APR 1.3.0 adopts 
+     the Unix behavior of inheriting any uninitialized streams as the 
+     parent's corresponding stdio stream, in such cases.  [William Rowe]
+
+Changes with APR 0.9.16
+
+  *) Win32 apr_file_read: Correctly handle completion-based read-to-EOF.
+     [Steven Naim <steven.naim googlemail.com>]
+
+  *) Fixed Win32 regression of StdOutput inheritance in apr_proc_create.
+     [William Rowe]
+
+Changes with APR 0.9.15
+
+  *) Solve WinNT inherited pipe leaks by mutexing apr_proc_create calls,
+     on WinNT (not WinCE, nor 9x) so that we toggle the inherited state 
+     of the stdin/out/err pipes.  All other file handles are treated as
+     not-inherited until apr_file_dup2'ed a std handle of this process, 
+     or while they are used by apr_proc_create.  [William Rowe]
+
+  *) Define the Mac OS/X filesystem_encoding as utf-8 (in previous
+     releases the interpretation would vary).  [Branko Čibej]
+
+  *) Fix day of year (tm_day) calculation for July. The bug only affects
+     Windows builds.  PR 42953.  [Davi Arnaut]

+  *) Provide folding in autogenerated .manifest files for Win32 builders
+     using VisualStudio 2005  [William Rowe]
+
+Changes with APR 0.9.12
+
+  *) Netware - add missing apu_version.c parsing for apu_version_string()

+     since 0.9.1.  [Brad Nicholes]
+
+Changes with APR 0.9.11
+
+  *) Synced get-version.sh to trunk to correctly retrieve 2 digit subversion,
+     which broke the 0.9.10 candidate.  [William Rowe]
+
+  *) Fixed 'make check' target to avoid invoking sub-programs of testshm,
+     testshmconsumer and testshmproducer.  [William Rowe]
+
+  *) Permit Win32 to seek to the point 2^32-1, by checking that result

+
+Changes with APR 0.9.10

+     which is started by the shell and which inherits the parent's
+     environment variables.  [Jeff Trawick]
+
+  *) Change default inter-process locking mechanisms: POSIX semaphores
+     and pthread cross-process mutexes are not used by default; on 
+     Solaris, fcntl locks are used by default.  [Joe Orton]
+

+
+  *) Provide workaround for socklen_t declaration problem with 64-bit

+     vendor compiler on ia64.  [Jeff Trawick, based on idea from
+     Madhusudan Mathihalli]
+
+  *) Return an error instead of silently failing when apr_poll() is
+     used with file descriptors >= FD_SETSIZE.  (Unix systems with

+
+  *) Ensure that apr_sockaddr_info_get() does not return anything
+     other than AF_INET and AF_INET6 addresses.  [Joe Orton]
+
+  *) Clarify that apr_dir_read() does not guarantee order of returned
+     entries as previously claimed.  [Joe Orton]
+
+  *) The whole codebase was relicensed and is now available under
+     the Apache License, Version 2.0 (http://www.apache.org/licenses).
+     [Apache Software Foundation]
+
+  *) Define apr_off_t as long rather than as off_t on platforms with a
+     32-bit off_t to prevent incompatibility with packages such as
+     Perl which redefine the size of off_t via _FILE_OFFSET_BITS on
+     some platforms.  [Ben Reser <ben reser.org>]
+
+  *) apr_socket_connect(): allow app to make subsequent call on 
+     non-blocking socket.  [Jeff Trawick]
+ 
+  *) Add apr_os_pipe_put_ex(), which allows the caller to tell APR
+     to establish a cleanup on the pipe.  [Jeff Trawick, Brad Nicholes]
+
+  *) Fix make_exports.awk to work with apr-iconv.  [Justin Erenkrantz]
+
+Changes with APR 0.9.4
+
+  *) win32: fix apr_file_dup() and apr_file_dup2() to dup the
+     ungetchar member [Stas Bekman]
+
+  *) Preserve leading '../' segments as when merging to an empty and
+     unrooted path - fixes a bug observed in SVN with Win32/Netware/OS2.
+     [Mike Pilato <cmpilato@collab.net>, William Rowe]
+
+  *) Work around a bug in Darwin when calling getnameinfo() on IPv4-mapped
+     IPv6-addresses.  [Colm MacCárthaigh <colm@stdlib.net>, Jeff Trawick,
+     Justin Erenkrantz]
+
+  *) Add apr_temp_dir_get() for getting the most suitable temp directory
+     [Mike Pilato <cmpilato@collab.net>, Thom May]
+
+  *) Modify apr_sockaddr_info_get to call the resolver when we
+     do not have a hostname.  Also, fix bugs in the getaddrinfo()
+     implementation.
+     [Colm MacCárthaigh <colm@stdlib.net>, Justin Erenkrantz]
+
+  *) Change the behavior of unix process 'trylock's to return
+     APR_ENOTIMPL instead of segfaulting, consistent with the
+     other lock implementations.  [William Rowe]
+
+  *) Fix a subtle race where the ownership of a unix nested
+     thread lock could be corrupted when the prior owner released
+     the lock with another thread waiting on the same lock.
+     [William Rowe]
+
+  *) apr_socket_data_set(): allow the same key to be used for
+     multiple sockets in the same pool.  [Jeff Trawick]
+
+  *) Add new table function apr_table_compress() and replace
+     red-black trees with mergesort in apr_table_overlap()
+     [Joe Schaefer <joe+gmane@sunstarsys.com>, Brian Pane]
+
+  *) Win32: Adopt Brian Havard's OS/2 rwlock implementation for
+     Windows [Marc Adkins, Bill Stoddard]
+
+  *) Add apr_proc_mutex_lockfile() for retrieving the name of the
+     file associated with a mutex.  [Jeff Trawick]
+
+  *) Don't require the lock file name to be passed into 
+     apr_proc_mutex_child_init() or apr_global_mutex_child_init().
+     This allows child init to work when the lock file was a temp
+     file created by APR.  (The problem only occurred with flock-
+     based mutexes.)  [Jeff Trawick]
+
+  *) When using a temporary file for flock- and fcntl-based mutexes, 
+     don't let the file be deleted on close.  For flock-based mutexes,
+     this corrects a fatal problem, since the file would disappear 
+     when a program was spawned and cleanup-for-exec was performed, 
+     and a subsequent attempt to perform child process mutex 
+     initialization would fail.  For fcntl-based mutexes, this was a 
+     very minor issue that resulted in a failing unlink() when the 
+     file was closed, since fcntl lock initialization always removes 
+     the file immediately.  [Jeff Trawick]
+
+  *) When writing to pipes with a timeout set, handle the situation
+     where the kernel says the pipe is writable but an attempt to
+     write <= PIPE_BUF bytes gets EAGAIN.  APR will now write whatever
+     data will fit.  APR applications that relied on the atomic nature
+     of relatively small pipe write requests may be affected.
+     PR 20295  [Mark Street <mark@faime.demon.co.uk>, Jeff Trawick]
+
+  *) Define _THREAD_SAFE for all compilations on AIX.  Previously
+     those of us who used the vendor compiler had it defined
+     implicitly and others did not.  The difference became obvious
+     with the recent thread safety fixes to apr_password_validate().
+     PR 20420  [Jeff Trawick]
+
+  *) For apr_proc_detach(APR_PROC_DETACH_FOREGROUND), don't treat
+     a setsid() failure as fatal, as the usual cause is that the
+     caller is already a process group leader.  PR 18519
+     [Jeff Trawick]
+
+  *) Fix some problems with non-blocking socket handling on unix
+     that resulted in infinite timeouts being used for non-blocking
+     sockets with apr_socket_connect() and some read/write calls.
+     [Jeff Trawick]
+
+  *) Fix a bug in socket timeout handling on unix that left the
+     socket non-blocking after disabling the timeout.
+     [Jacob Craig Lewallen <jlewalle@cs.ucr.edu>]
+
+  *) Added flag APR_FILE_ATTR_HIDDEN for manipulating the "hidden"
+     file attribute on Windows and OS/2.  [Branko Čibej]
+
+  *) SECURITY [CAN-2003-0245]: Fixed a bug that could be triggered
+     remotely through mod_dav and possibly other mechanisms, causing
+     an Apache child process to crash.  The crash was first reported
+     by David Endler <DEndler@iDefense.com> and was researched and
+     fixed by Joe Orton <jorton@redhat.com>.  Details will be released
+     on 30 May 2003.
+
+  *) apr_proc_wait(): Handle interrupted waitpid(2) calls by calling
+     it repeatedly until it succeeds or fails with errno other than
+     EINTR.  This hides this UNIX-specific behavior from APR clients.
+
+  *) Removed the solaris-specific atomic code, due to licence
+     concerns (it was MPL 1.0, and the author could not be contacted)
+     [Ian Holsman]
+
+  *) apr_file_gets(): Return APR_SUCCESS if any characters are
+     returned.  Any I/O errors or EOF will be reported on the
+     next call.  Callers that are coded to expect returned 
+     data + APR_EOF when there is no final newline are affected 
+     by this change.  [Jeff Trawick]
+
+  *) apr_proc_create() on Unix: Make the APR_SHELLCMD mode work
+     when there is more than one program argument passed in.
+     [Jeff Trawick]
+
+  *) Add --cc and --cpp flags to apr-config.  [Jeff Trawick]
+
+  *) Don't segfault trying to close a file in error paths of flock
+     and fcntl mutex creation.  PR 19036  [Jeff Trawick]
+
+  *) Add %pT support to apr_snprintf() for printing an apr_os_thread_t.

+
+  *) Add APR_TCP_NODELAY_INHERITED & APR_O_NONBLOCK_INHERITED to apr.hw
+     [Allan Edwards]
+
+  *) Add APR_UINT64_T_HEX_FMT.  [Jeff Trawick]
+
+  *) Add parameter to APR_SUBDIR_CONFIG to drop options passed to configure
+     before the subdir's configure is invoked.
+     [Jeff Trawick, Justin Erenkrantz]
+
+  *) Implement APR_SO_RCVBUF socket option on Unix.  
+     [Adam Sussman <myddryn@vishnu.vidya.com>]
+
+  *) Don't add the math library (-lm) if the modf() function
+     is already available via libc.  [Roy Fielding]
+
+  *) Solaris cc: Don't use the -mt option for threaded builds.  That
+     is for non-Posix threading, and the use of it prevented us from
+     linking with -lpthread, which in turn caused weird problems for
+     APR applications.  [Kristofer Spinka <kspinka@style.net>]
+
+  *) OS/2: apr_stat() fixes - When a character device is stat'ed, 
+     fill in finfo.name if it was asked for.  Return APR_INCOMPLETE 
+     when appropriate.  Addresses httpd incident [CAN-2003-0134].
+     [Brian Havard]
+
+Changes with APR 0.9.3
+
+  *) Don't enable posixsem, at build time, on systems where sem_t *
+     won't "fit" into an int (sizeof-wise). Also, better error handling
+     when we fail to create a posixsem. PR 17186 [Scott Herod
+     <sherod@pillardata.com>, Jim Jagielski]
+

+     [Bjoern A. Zeeb <bz@zabbadoz.net>, William Rowe, Joe Orton]
+

+     Define APR_INT64_T_FMT_LEN on Windows and Netware.  [Branko Čibej]
+
+  *) Correct apr_file_gets() on OS2 and Win32 so that '\r's are no longer
+     eaten, and apr_file_gets() -> apr_file_puts() moves the contents
+     uncorrupted.  [William Rowe]

+     This allows us to actually create WRITEABLE MMAPs.
+     [Ed Korthof <ed@apache.org>]
+
+  *) Completely revamp configure so that it preserves the standard make
+     variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
+     the configure additions to EXTRA_* variables.  Also, allow the user
+     to specify NOTEST_* values for all of the above, which eliminates the
+     need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM.  Fix the setting
+     of INCLUDES and EXTRA_INCLUDES.  Check flags as they are added to
+     avoid pointless duplications.  Fix the order in which flags are given
+     on the compile and link lines.  [Roy Fielding]
+ 
+  *) Fix DSO code on HP/UX.  We have to use == not =, and it makes more
+     sense to actually return errno, so that the return code means 
+     something.  [Ryan Bloom]
+
+  *) Clean up conditionals in unix DSO code so that we decide based on
+     the dynamic loading implementation, which we noticed at configure
+     time, instead of by operating system.
+     [Wilfredo Sanchez]
+
+  *) Add DSO support for dyld platforms (Darwin/Mac OS and OpenStep).
+     [Wilfredo Sanchez]
+
+  *) Amend the time code to better deal with time zones.
+     [David Reid]
+
+  *) Carefully select an appropriate native type for apr_int64_t and
+     define its format as APR_INT64_T_FMT and literal using APR_INT64_C().
+     [Justin Erenkrantz, William Rowe]
+
+  *) Make clean, distclean, and extraclean consistently according to the
+     Gnu makefile guidelines.  [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
+
+  *) Initial implementation of of apr_filepath (get/set/parse_root and 
+     merge) for Windows.  [William Rowe]
+
+  *) Cleaned up implementation of of apr_filepath (get/set/parse_root
+     and merge) for Unix.  [Greg Stein, William Rowe]
+
+  *) Fixup the --enable-libtool option.  This allows the test directory
+     to compile again.  The test directory still doesn't work when
+     APR is configured without libtool.  [Ryan Bloom]
+
+  *) If we don't have sigwait() in the system, see if sigsuspend() is
+     available, and use that instead. [Wilfredo Sanchez]
+
+  *) Make libtool optional at configure time.  This is done with 
+     --disable-libtool.  [Ryan Bloom]
+
+  *) Recognize systems where the TCP_NODELAY setting is inherited from
+     the listening socket, and optimize apr_setsockopt(APR_TCP_NODELAY)
+     accordingly.  [Jeff Trawick]
+
+  *) Recognize the presence of getnameinfo() on Tru64.  [David Reid]
+
+  *) Allow APR to be installed. [Ryan Bloom]
+
+  *) Generate config.nice for easy re-run of configure. [Roy Fielding]
+
+  *) Define preprocessor flags in CPPFLAGS instead of CFLAGS and
+     bring some sanity to the compiler command-lines. [Roy Fielding]
+
+  *) Use the dso/aix subdirectory for older versions of AIX and fix 
+     a number of bugs in the dso code in that directory.
+     [Victor Orlikowski]
+
+  *) Allow libtool 1.3b to be used.  [Victor Orlikowski]
+
+  *) Misc. Win32 fixes: Set the pool pointer in apr_sockaddr_t 
+     structures created with the apr_socket_t to prevent segfault 
+     in certain apps.  Flush unwritten buffered data when the file 
+     is closed.  [Jeff Trawick]
+
+  *) Win32: Get APR to compile with MSVC 5.0 (a.k.a. VC97).
+     PR #7489  [Jeff Trawick]
+
+  *) First draft implementation of apr_filepath (get/set/parse_root
+     and merge) for Unix.  [William Rowe]
+
+  *) Add apr_ipsubnet_create() and apr_ipsubnet_test() for testing
+     whether or not an address is within a subnet.  [Jeff Trawick]
+
+  *) Add apr_sendto and apr_recvfrom for Unix.  Start of adding UDP
+     support.  [David Reid]
+
+  *) Add a method to get the password from the system for a given
+     user.  [John Barbee <jbarbee@covalent.net>]
+
+  *) Change the include path order, so that we look for included files
+     in the APR paths first, and the system paths second.
+     [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
+
+  *) Add a with-sendfile option, so that people on platforms without a
+     sendfile implementation for APR can easily disable it from the 
+     configure line.  [Ryan Bloom]
+
+  *) Change the check for netinet/tcp.h to work around an issue with
+     that header file on IRIX 6.5 which prevented it from being
+     detected.  PR #6459  [Jeff Trawick]
+
+  *) Introduce apr_get_userid to return a named user's apr_uid_t and
+     apr_gid_t across platforms [Cliff Woolley, William Rowe]
+
+  *) In apr_shm_init(), check the retcode from mm_malloc().  Previously,
+     we segfaulted here if mm_malloc() failed to get a lock.  An example
+     error scenario is when the lock file lives on a filesystem which
+     doesn't support locking.  [Jeff Trawick]
+
+  *) Name protected the autoconf macros defined by APR.  Moved the
+     REENTRANCY_FLAGS settings into apr_hints.m4. Inlined the
+     APR_PREPARE_MM_DIR macro because it could only be used once.
+     Removed the unused macros MY_TRY_RUN, MY_TRY_RUN_NATIVE, and
+     AC_USE_FUNCTION.  Added some macro comments.  [Roy Fielding]
+
+  *) Cope with BSDi installations where the default make has been
+     replaced with GNU make.  [Joe Orton <joe@manyfish.co.uk>]
+
+  *) Changed apr/helpers to apr/build to be consistent with other Apache
+     source trees.  Added make variables to rules.mk.in that point to the
+     builders directory and its scripts.  Updated buildconf, configure.in,
+     and Makefile.in files to create and use the new scripts.  Moved scandoc
+     to scandoc.pl and its default.pl template to scandoc_template.pl.
+     [Roy Fielding]
+
+  *) Updated config.guess and config.sub to GNU libtool 1.3.5 features,
+     with the Apache additions for OS/390 and OS/2 emx.  [Roy Fielding]
+
+  *) Moved hints.m4, apr_common.m4, and helpers/apr-conf.m4 into the
+     new build directory as apr_hints.m4, apr_common.m4, apr_network.m4,
+     and apr_threads.m4.  [Roy Fielding]
+
+  *) Get apr_sendfile() working on HP-UX.  This gets APR to build on
+     HP-UX without having to turn off APR_HAS_SENDFILE.  [Jeff Trawick]
+
+  *) Force FreeBSD to compile without threads by default.  To enable
+     threads, use --enable-threads on the configure line.
+     [Ryan Bloom]
+
+  *) Purge system password buffer before returning from apr_password_get.
+     No longer abuses bufsize argument on return.  [William Rowe]
+
+  *) Moved the prototypes for apr_snprintf and apr_vsnprintf to the
+     apr_strings.h header, from apr_lib.h.  This location makes more
+     sense.  [Ryan Bloom]
+
+  *) Added the APR_TRY_COMPILE_NO_WARNING configure macro for testing a
+     compile with -Werror as well as the APR_CHECK_ICONV_INBUF macro to
+     test for annoying iconv prototype differences.
+     [Jeff Trawick, Roy Fielding]
+
+  *) Fix a problem with configure on NetBSD.  We must include sys/types.h
+     for some platforms.  [jun-ichiro hagino <itojun@kame.net>]
+
+  *) Some fixes in the Win32 time support.
+     (IsLeapYear): New macro for quickly figgerin' out if a given year is a 
+     leap year. (SystemTimeToAprExpTime): Perform the calculation of
+     tm_yday.  Also, negate the sign of the tm_gmtoff field to be
+     consistent with Unix platforms and APR header file comments.
+     [Mike Pilato]
+
+  *) Implement WinNT Unix'ish permissions. [William Rowe]
+
+  *) Corrected an OS2'ism of apr_get_home_directory.  OS2 now returns the
+     proper directory, including the user's name.
+
+  *) Removed private os2errno.h and integrated the OS2 network error codes
+     into apr_errno.h for optimized error tests (APR_STATUS_IS_EFOO(rv)).
+     [William Rowe]
+
+  *) Moved inclusion of <os2.h> header from multiple modules into apr.h
+     [William Rowe]
+
+  *) Added apr_compare_users() and apr_compare_groups() for more complex
+     apr_uid_t and apr_gid_t structures.  Enabled both .user and .group
+     results from WinNT/2000 stat/getfileinfo, but expect to find that 
+     .group is 'None' in most cases.  [William Rowe]
+
+  *) Replace configure --with-optim option by using the environment
+     variable OPTIM instead.  This is needed because configure options
+     do not support multiple flags separated by spaces.  [Roy Fielding]
+
+  *) Eliminate the APR_SIG* aliases for standard signal names,
+     since they serve no useful purpose.  [Roy Fielding]
+
+  *) Abstracted apr_get_username and apr_get_groupname for unix and win32.
+     Modified Win32 apr_uid_t and apr_gid_t to use PSIDs, and elimintated
+     the uid_t and gid_t definitions.  [William Rowe]
+
+  *) Radically refactored apr_stat/lstat/getfileinfo/dir_read for Win32
+     to assure we are retrieving what we expect to retrieve, and reporting
+     the correct result (APR_SUCCESS or APR_INCOMPLETE).  The potential
+     for a bit more optimization still remains.  [William Rowe]
+
+  *) While we have the future opportunity to cache the apr_stat'ed file
+     handle for a very fast open (dup handle) on Win32, patched to close
+     that file after a stat always.  Needs a new semantic before we leave
+     handles dangling when the user intends to rm.  [William Rowe]
+
+  *) Correct Win32 apr_stat/lstat/getfileinfo/dir_read to all zero out
+     the finfo buffer on success (or incomplete success).  [William Rowe]
+
+  *) Fix Win32/Unix apr_lstat to throw the .valid bit APR_FINFO_LINK to
+     indicate we attempted to open the link.  Only the .filetype APR_LNK
+     reflects if the file found was, in fact, a link.   [William Rowe]
+
+  *) Fixed apr_open and apr_rename to function on Win9x.
+     [Mike Pilato <cmpilato@collab.net>] 
+  
+  *) Add apr_open_stdout.  This mirrors apr_open_stderr, except it works
+     on stdout.  [Mike Pilato <cmpilato@collab.net>]
+
+  *) Fix bug in file_io/unix/dir.c.  There is no such thing as a dirent,
+     it must be a struct dirent.  
+     [Kevin Pilch-Bisson <kevin@pilch-bisson.net>]
+
+  *) Fix the configure script so that we can build from a different
+     directory.  [Kevin Pilch-Bisson <kevin@pilch-bisson.net>]
+
+  *) Introduce the wanted flag argument to the apr_stat/lstat/getfileinfo
+     family of functions.  This change allows the user to determine what
+     platform-specific file information is retrieved, to optimize both
+     portability and performance.  [William Rowe]
+
+  *) Fix make depend.  [Ryan Bloom]
+
+  *) All dso implementations now register a cleanup to unload the DSO
+     when it is loaded.  If the pool is removed, we really do need to
+     remove the DSO.  In the past, different platforms behaved differently
+     it this respect.  [Ryan Bloom]
+
+  *) Add linkage declarations to the DSO code.
+     [Gregory Nicholls <gnicholls@level8.com>]
+
+  *) Some adjustment of hints.m4 setting flags (used to check if null
+     first) and added some verbosity. [Jim Jagielski]
+
+  *) Specify APR_DECLARE to some of the APR functions.  This helps linking
+     on some operating systems.  [Gregory Nicholls <gnicholls@level8.com>]
+
+  *) Libtool'ized APR and converted all the makefiles to share rules
+     from helpers/rules.mk. [Greg Stein]
+
+  *) Remove a warning on FreeBSD.  FreeBSD defines TCP_NO_PUSH, but we
+     don't actually use it.  This causes os_cork to be defined but not
+     used.  This patch keeps us from defining os_cork and os_uncork on
+     FreeBSD.  [Ryan Bloom]
+
+  *) Keep apr_terminate from seg faulting on terminate.  This is
+     happening on systems that do not NULL out locks when they are
+     destroyed.  To keep this from happening, we set the locks to
+     NULL after destroying them in apr_terminate, and we have to 
+     check for NULL in free_blocks.  
+     [Allan Edwards and Gregory Nicholls <gnicholls@level8.com>]
+
+  *) Remove the ability to allocate memory out of a NULL pool.
+     [Ryan Bloom]
+
+  *) Add an APR_GET_POOL macro to get a pool from any APR type that has
+     a pool.  This requires that ALL apr types put the pool as the first
+     field in their structure. [Ryan Bloom]
+
+  *) Begin to remove the ability to allocate out of NULL pools.  The first
+     problem to solve, is that we need an apr_lock in order to allocate
+     pools, so that we can lock things out when allocating.  So, how do we
+     allocate locks without a pool to allocate from?  The answer is to create
+     a global_apr_pool, which is a bootstrapping pool.  There should NEVER
+     be a sub-pool off this pool, and it is static to an APR file.  This is
+     only used to allow us to allocate the locks cleanly, without using the
+     NULL pool hack.  [Ryan Bloom]
+
+  *) Fix a logic error in the poll code when implemented using select.
+     [Nick Caruso <ncaruso@gamesville.com>]
+
+  *) FreeBSD does not support sendfile() in combination with threads
+     before version 4.2.  We no longer even try to support it.
+     [Ryan Bloom]
+
+  *) On FreeBSD, it is possible for the first call to sendfile to
+     get EAGAIN, but still send some data.  This means that we cannot
+     call sendfile and then check for EAGAIN, and then wait and call
+     sendfile again.  If we do that, then we are likely to send the
+     first chunk of data twice, once in the first call and once in the
+     second.  If we are using a timed write, then we check to make sure
+     we can send data before trying to send it. [Ryan Bloom]
+
+  *) Cleanup to help Apache support programs build cleanly.
+     [Cliff Woolley <cliffwoolley@yahoo.com>]
+
+  *) Cleanup some compiler warnings on Solaris
+     [Dale Ghent <daleg@elemental.org>]
+
+  *) apr_getaddrinfo() can now return multiple addresses for a host
+     via the next field in apr_sockaddr_t.  [Jeff Trawick]
+
+  *) Tighten up the check for getaddrinfo().  If it can't figure out
+     the appropriate address family for 127.0.0.1, it fails.  
+     Unfortunately, Tru64 fails this test so we won't do IPv6 on
+     Tru64.  [Jeff Trawick]
+
+  *) Rename apr_opendir to apr_dir_open.  [Ryan Bloom]
+
+  *) apr_snprintf()'s %pI format string now takes apr_sockaddr_t *
+     instead of sockaddr_in *.  [Jeff Trawick]
+
+  *) Fix a bug in apr_accept() for Win32 and Unix where the local 
+     apr_sockaddr_t in the new connected socket was not initialized
+     properly.  This could result in a bad string for apr_get_ipaddr(),
+     among other things.  [Jeff Trawick]
+
+  *) Add apr_getnameinfo(), a replacement for apr_get_hostname() which
+     supports IPv6 and will be friendlier for use with eventual 
+     SOCK_DGRAM support.  apr_get_hostname() is gone.  [Jeff Trawick]
+
+
+Changes with APR a9
+
+  *) Removed the iconv implementation from the i18n/unix/iconv branch.
+     This now resides in the apr-iconv repository, and will be ported
+     over time to use native apr types (e.g. apr_dso) for portability.
+
+  *) Only support IPv6 if we have sockaddr_in and a working 
+     getaddrinfo().  [Jeff Trawick]
+
+  *) Add apr_parse_addr_port() for parsing the hostname:port portion
+     of URLs and similar strings.  [Jeff Trawick]
+
+  *) Add Win32 MMAP support [William Rowe]
+
+  *) Allow the APR programmer to specify if the MMAP is read-only or
+     write-able.
+     [Ryan Bloom and Will Rowe]
+
+  *) Check more carefully for getaddrinfo().  Accept those that
+     require <netdb.h> to be included (e.g., Tru64).  Reject those that 
+     fail a very basic operational test (e.g., AIX).  [Jeff Trawick]
+
+  *) Add apr_make_os_sock() for constructing a fully-capable APR
+     socket.  [Jeff Trawick]
+
+  *) Make APR's shared memory routines always allocate enough memory
+     for the requested segment, the MM internal types, and the APR
+     internal types.
+     [Ryan Bloom]
+
+  *) Add APR_SIZE_T_FMT.  Get the other APR_xx_T_FMT variables
+     defined properly on AIX.  [Jeff Trawick]
+
+  *) network API changes: get rid of apr_get_socket_inaddr(), 
+     apr_get_remote_name(), and apr_get_local_name()  [Jeff Trawick]
+
+  *) Add a step at configure time to create a file at the top-level,
+     apr.exports, which lists every function exported by APR.  The
+     file is generated by a script in helpers, that reads each header
+     file.
+     [Ryan Bloom]
+
+  *) Lock config changes: Detect SysV sem capability by the presence of
+     sempaphore functions, not by the presence of union semun.  New
+     config variable apr_lock_method can override autodetection of the 
+     apr_lock implementation method.  For now, hints.m4 uses it to select 
+     SysV semaphores for OS/390.  New config variable 
+     apr_process_lock_is_global specifies that the selected inter-process
+     lock method is sufficient for APR_LOCKALL (i.e., it blocks all
+     threads and processes).  For now, hints.m4 turns on this flag for
+     OS/390.  [Jeff Trawick]
+     
+  *) Get APR_OFF_T_FMT defined properly on Solaris Sparc.
+     [Jeff Trawick]
+
+
+Changes with APR a8
+
+  *) Change the name of the sa_len field in apr_sockaddr_t to salen.
+     Some platforms have a macro named sa_len.
+     [Tony Finch]
+
+  *) apr_set_port(), apr_get_port(), apr_set_ipaddr(), and apr_get_ipaddr()
+     now take apr_sockaddr_t as a parameter instead of apr_socket_t +
+     apr_interface_e.  This will allow the same routines to be used with
+     datagram APIs to be added later.  Note that code which calls 
+     apr_set_ipaddr() should probably be changed to call apr_getaddrinfo()
+     for protocol independence.  [Jeff Trawick]
+
+  *) apr_create_tcp_socket() has been removed.  Use apr_create_socket()
+     instead.  [Jeff Trawick]
+
+  *) Source was moved from the apache-2.0 repository.  For all CHANGES
