-  *) When using shmget-based shared memory, the ID used for ftok is
-     now an APR hash of the filename instead of the constant '1'.
-     We do this to help avoid collisions. PR 53996 [Jim Jagielski]
+  *) apr_proc/global_mutex: Fix API regarding the native OS mutexes
+     accessors from/to available APR mechanisms, adding the new functions

-     <ivan visualsvn.com>]
-
-  *) Windows:  Create named shared memory segments under the "Local"
-     namespace if the caller is unprivileged, fixing an inability of
-     unprivileged callers to use apr_shm_create() with named shared
-     memory segments under recent Windows.  As before, shared memory
-     segments are created under the "Global" namespace for privileged
-     callers.  Add apr_shm_create_ex() and apr_shm_attach_ex(), which
-     provide the ability to override the normal namespace selection.
-     [Jeff Trawick]

-     [Jeff Trawick]
+  *) apr_skiplist: Add apr_skiplist_addne*() family to preserve existing
+     values (no duplicate), add apr_skiplist_size(), apr_skiplist_height()
+     and apr_skiplist_preheight() to get the corresponding current values,
+     and apr_skiplist_set_preheight() to modify it. [ Yann Ylavic ]
 
-  *) File info APIs: Fix calculation of atime and mtime on AIX. PR 51146.
-     [Ruediger Pluem]
+  *) Add new --enable-allocator-guard-pages which is like allocator-uses-mmap,
+     but will also add inaccessible guard pages before and after each memnode.
+     This will result in higher ressource usage but allow to find/protect
+     against certain buffer overflow/overread bugs. Under Linux, it may be
+     necessary to increase /proc/sys/vm/max_map_count . [Stefan Fritsch]
 
-  *) Add the apr_escape interface. [Graham Leggett]
+  *) apr_skiplist: Add apr_skiplist_add() to support multiple values.
 
-  *) Cygwin build fixes.  PRs 51016 and 55586.  [Carlo Bramini
-     <carlo.bramix libero.it>] 
+  *) Add new --enable-pool-concurrency-check configure option to detect
+     thread-unsafe concurrent accesses to pools. Runtime costs should be
+     relatively low. [Stefan Fritsch]
 
-  *) Add apr_skiplist family. [Jim Jagielski]
+  *) Add support code to teach valgrind about APR pools and allocators.
+     [Stefan Fritsch]
 
-  *) Add experimental cmake-based build system for Windows.  Refer to 
-     README.cmake for more information.  [Jeff Trawick, Tom Donovan]
+  *) Add apr_sockaddr_info_copy(), for making a deep copy of an
+     apr_sockaddr_t into a specified pool.  [Yann Ylavic
+     <ylavic.dev gmail.com>]
 
-  *) Add the apr_table_getm() call, which transparently handles the
-     merging of keys with multiple values. [Graham Leggett]
+  *) Added Unix domain socket support.
+     [Mladen Turk]
 
-  *) Add apr_hash_this_key(), apr_hash_this_key_len(), and 
-     apr_hash_this_val() for easier access to those attributes from
-     a hash iterator.  [Hyrum K. Wright <hyrum_wright mail.utexas.edu>]
+  *) Add apr_shm_delete() to compliment apr_shm_remove().
+     [Jim Jagielski]
 
-  *) MinGW/MSYS:  Support shared builds of APR, other general improvements
-     to support of this toolchain.  PR 46175.  [Carlo Bramini 
-     <carlo.bramix libero.it>]  
+  *) Intruduce APR_PERMS_SET macros for setting the owner/group on
+     objects. Currently only implemented for shm, proc and global
+     mutexes on posix platforms.
+     [Mladen Turk]
 
-  *) Improve platform detection by updating config.guess and config.sub.
-     [Rainer Jung]
+  *) Add apr_escape_ldap() and apr_pescape_ldap(), escaping characters
+     as described by RFC4514 and RFC4515 respectively. [Graham Leggett]
 
-  *) apr_socket_opt_set: Add support for APR_SO_BROADCAST. PR 46389.
-     [Armin Müller <mueller itestra com>]
+Changes for APR 1.5.x and later:
 
-  *) Enable platform specific support for the opening of a file or
-     pipe in non-blocking mode through the APR_FOPEN_NONBLOCK flag.
-     [Graham Leggett]
+  *) http://svn.apache.org/viewvc/apr/apr/branches/1.5.x/CHANGES?view=markup

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath [OPTION]...'
+
+# Short help message in response to '-h' and '--help'.  Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.

+ * @defgroup apr_cstr C (POSIX) locale string functions

+ *
+ * The apr_cstr_* functions provide traditional C char * string text handling,
+ * and notabilty they treat all text in the C (a.k.a. POSIX) locale using the
+ * minimal POSIX character set, represented in either ASCII or a corresponding
+ * EBCDIC subset.
+ *
+ * Character values outside of that set are treated as opaque bytes, and all
+ * multi-byte character sequences are handled as individual distinct octets.
+ *
+ * Multi-byte characters sequences whose octets fall in the ASCII range cause
+ * unexpected results, such as in the ISO-2022-JP code page where ASCII octets
+ * occur within both shift-state and multibyte sequences.
+ *
+ * In the case of the UTF-8 encoding, all multibyte characters all fall outside
+ * of the C/POSIX range of characters, so these functions are generally safe
+ * to use on UTF-8 strings. The programmer must be aware that each octet may
+ * not represent a distinct printable character in such encodings.
+ *
+ * The standard C99/POSIX string functions, rather than apr_cstr, should be
+ * used in all cases where the current locale and encoding of the text is
+ * significant.
