+Changes with APR-Util 1.4.1
+
+  *) Apply Windows build fixes for the apr_crypto API. [Mladen Turk]
+
+Changes with APR-util 1.4.0
+
+  *) apr_ldap_init: Pass secure=1 to ldapssl_init() with Solaris LDAP SDK.
+     PR: 42682 [Stefan Fritsch]
+
+  *) apr_memcache_server_create: Fix possible segfault. PR 51064.
+     [Michajlo Matijkiw <michajlo_matijkiw comcast com>]
+
+  *) apr_thread_pool: Fix thread unsafe pool usage. [Stefan Fritsch]
+
+  *) Do not include apr.h and apr_errno.h from system search path in
+     apu_errno.h. PR 46487 [Rainer Jung]
+
+  *) Add optional dbm, openssl and nss subpackages to the RPM spec file.
+     [Graham Leggett]
+
+  *) apr_dbd_freetds: The sybdb.h header file might be freetds/sybdb.h
+     or sybdb.h. [Graham Leggett]
+
+  *) Add apr_crypto implementations for OpenSSL and Mozilla NSS. Add a unit
+     test to verify the interoperability of the two modules. Builds default
+     to disabled unless explicitly enabled.
+     [Graham Leggett]
+
+  *) Add the apr_crypto interface, a rewrite of the earlier apr_ssl code,
+     based on the modular dso interface used for dbd and ldap. Initially,
+     the interface supports symmetrical encryption and decryption. The
+     purpose of the interface is to offer portable and interoperable
+     access to basic crypto using the native crypto libraries present on
+     each platform.  [Graham Leggett]
+
+  *) Add trace probes to hooks, making it easier to inspect APR Hook based
+     applications with DTrace or other such mechanisms.
+     [Theo Schlossnagle <jesus omniti.com>, generalized by Jeff Trawick]

+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+
+      (b) You must cause any modified files to carry prominent notices

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Apache Portable Runtime Utility Library README
+----------------------------------------------
+
+   The Apache Portable Runtime Utility Library provides a predictable
+   and consistent interface to underlying client library interfaces.
+   This API assures predictable if not identical behavior regardless
+   of which libraries are available on a given platform.
+
+   APR and its companion libraries are implemented entirely in C
+   and provide a common programming interface across a wide variety
+   of operating system platforms without sacrificing performance.
+   Currently supported platforms include:
+
+     UNIX variants
+     Windows
+     Netware
+     Mac OS X
+     OS/2
+
+   To give a brief overview, the primary core
+   subsystems of APR-util 1.3 include the following:
+
+     Hashing and UUID services
+     Multiple SQL DBD client interfaces
+     Multiple flat-database DBM client interfaces
+     Typesafe function Hooks abstraction
+     LDAP SSL connections for a variety of LDAP toolkits   
+     MemCache interface
+     Date parsing rourtines
+     Resource Lists
+     Thread Pools
+     Queues
+     Relocatable Memory Management functions
+     String filename-style pattern matching
+     URI Parsing
+     Charset translation (iconv based)
+     XML parsing (expat based)
+
+   For a more complete list, please refer to the following URLs:
+
+     http://apr.apache.org/docs/apr-util/modules.html
+
+   Users of APR 0.9 should be aware that migrating to the APR 1.x
+   programming interfaces may require some adjustments; APR 1.x is
+   neither source nor binary compatible with earlier APR 0.9 releases.
+   Users of APR 1.x can expect consistent interfaces and binary backwards
+   compatibility throughout the entire APR 1.x release cycle, as defined
+   in our versioning rules:
+
+     http://apr.apache.org/versioning.html
+
+   APR is already used extensively by the Apache HTTP Server
+   version 2 and the Subversion revision control system, to
+   name but a few.  We list all known projects using APR at
+   http://apr.apache.org/projects.html -- so please let us know
+   if you find our libraries useful in your own projects!
+
+
+Database Providers
+------------------
+As of apr-util version 1.2.11, MySQL DBD driver is shipped as part of the
+distribution.  However, to avoid licensing incompatibilities, it is not
+built by default.  To enable MySQL support, use the --with-mysql option,
+but be aware that the MySQL license may introduce licensing implications
+for your compiled code.  Similarly, the bindings for propritary drivers
+such as Oracle (--with-oracle option) must also be explicitly enabled.
+
+On windows, selection of supported drivers is via the environment values
+DBD_LIST (for freetds, mysql, oracle, pgsql, sqlite2 and/or sqlite3) 
+and DBM_LIST (db and/or gdbm).  DBD odbc and DBM sdbm are unconditionally
+compiled and installed, do not include these in the list.
+
+Whenever distributing apr-util in combination with database client 
+drivers, always review the license requirements of all components.
+
+
+Cryptographic Software Notice
+-----------------------------
+This distribution includes cryptographic software.  The country in 
+which you currently reside may have restrictions on the import, 
+possession, use, and/or re-export to another country, of 
+encryption software.  BEFORE using any encryption software, please 
+check your country's laws, regulations and policies concerning the
+import, possession, or use, and re-export of encryption software, to 
+see if this is permitted.  See http://www.wassenaar.org/ for more
+information.
+
+The U.S. Government Department of Commerce, Bureau of Industry and
+Security (BIS), has classified this software as Export Commodity 
+Control Number (ECCN) 5D002.C.1, which includes information security
+software using or performing cryptographic functions with asymmetric
+algorithms.  The form and manner of this Apache Software Foundation
+distribution makes it eligible for export under the License Exception
+ENC Technology Software Unrestricted (TSU) exception (see the BIS 
+Export Administration Regulations, Section 740.13) for both object 
+code and source code.
+
+The following provides more details on the included cryptographic
+software:
+
+  APR-Util provides an abstract interface for symmetrical cryptographic
+  functions that make use of a general-purpose encryption library,
+  such as OpenSSL, NSS, or the operating system's platform-specific
+  facilities. This interface is known as the apr_crypto interface,
+  with implementation beneath the /crypto directory.
+
+  APR-Util provides an abstract interface for SSL encrypted LDAP (ldaps
+  and STARTTLS style) connections, which can be powered by OpenLDAP, 
+  Netscape LDAP SDK, Mozilla LDAP SDK, or other platform specific ldap
+  interfaces.

+Usage: apu-$APRUTIL_MAJOR_VERSION-config [OPTION]
+
+Known values for OPTION are:
+  --prefix[=DIR]    change prefix to DIR
+  --bindir          print location where binaries are installed
+  --includes        print include information
+  --includedir      print location where headers are installed
+  --ldflags         print linker flags
+  --libs            print library information
+  --avoid-ldap      do not include ldap library information with --libs
+  --ldap-libs       print library information to link with ldap
+  --avoid-dbm       do not include DBM library information with --libs
+  --dbm-libs        print additional library information to link with DBM
+  --srcdir          print APR-util source directory
+  --link-ld         print link switch(es) for linking to APR-util
+  --link-libtool    print the libtool inputs for linking to APR-util
+  --apu-la-file     print the path to the .la file, if available
+  --old-expat       indicate if APR-util was built against an old expat
+  --db-version      print the DB version
+  --version         print APR-util's version as a dotted triple
+  --help            print this help
+
+When linking with libtool, an application should do something like:
+  APU_LIBS="\`apu-$APRUTIL_MAJOR_VERSION-config --link-libtool --libs\`"
+or when linking directly:
+  APU_LIBS="\`apu-$APRUTIL_MAJOR_VERSION-config --link-ld --libs\`"
+
+An application should use the results of --includes, and --ldflags in
+their build process.

+ * The exported function:
+ *
+ * 	 apr_sha1_base64(const char *clear, int len, char *out);
+ *
+ * provides a means to SHA1 crypt/encode a plaintext password in
+ * a way which makes password files compatible with those commonly
+ * used in netscape web and ldap installations. It was put together
+ * by Clinton Wong <clintdw@netcom.com>, who also notes that:
+ *
+ * Note: SHA1 support is useful for migration purposes, but is less
+ *     secure than Apache's password format, since Apache's (MD5)
+ *     password format uses a random eight character salt to generate
+ *     one of many possible hashes for the same password.  Netscape
+ *     uses plain SHA1 without a salt, so the same password
+ *     will always generate the same hash, making it easier
+ *     to break since the search space is smaller.
+ *
+ * See also the documentation in support/SHA1 as to hints on how to
+ * migrate an existing netscape installation and other supplied utitlites.
+ *
+ * This software also makes use of the following component:
+ *
+ * NIST Secure Hash Algorithm
+ *  	heavily modified by Uwe Hollerbach uh@alumni.caltech edu
+ *	from Peter C. Gutmann's implementation as found in

+ * Symmetric Key types understood by the library.
+ *
+ * NOTE: It is expected that this list will grow over time.
+ *
+ * Interoperability Matrix:
+ *
+ * The matrix is based on the testcrypto.c unit test, which attempts to
+ * test whether a simple encrypt/decrypt will succeed, as well as testing
+ * whether an encrypted string by one library can be decrypted by the
+ * others.
+ *
+ * Some libraries will successfully encrypt and decrypt their own data,
+ * but won't decrypt data from another library. It is hoped that over
+ * time these anomalies will be found and fixed, but until then it is
+ * recommended that ciphers are chosen that interoperate across platform.
+ *
+ * An X below means the test passes, it does not necessarily mean that
+ * encryption performed is correct or secure. Applications should stick
+ * to ciphers that pass the interoperablity tests on the right hand side
+ * of the table.
+ *
+ * Aligned data is data whose length is a multiple of the block size for
+ * the chosen cipher. Padded data is data that is not aligned by block
+ * size and must be padded by the crypto library.
+ *
+ *                  OpenSSL      NSS      Interop
+ *                 Align Pad  Align Pad  Align Pad
