<ol type="1">
<li>Fix a bug where Win9X systems region names could collide.</li>
<li>Fix a bug where configuring Berkeley DB to build the C++ API without also configuring for a shared library build would fail to build the C++ library. [#4343]</li>
<li>Change Berkeley DB installation to not strip binaries if --enable-debug was specified as a configuration option. [#4318]</li>
<li>Add the -pthread flag to AIX, FreeBSD and OSF/1 library loads. [#4350]</li>
<li>Fix a bug where the Berkeley DB 1.85 compatibility API failed to load in the 3.3.11 release. [#4368]</li>
<li>Port the Berkeley DB utility programs to the VxWorks environment. [#4378]</li>
<li>Made change to configuration so that dynamic libraries link correctly when C++ is used on AIX. [#4381]</li>
<li> Fix a variety of problems that prevented the Berkeley DB source tree from building on systems without ANSI C compiler support (for example, SunOS 4.X). [#4398]</li>
<li>Added missing DbMultiple*Iterator Java files to Makefile.in. [#4404]</li>
<li>Fix a bug that could prevent the db_dump185 utility from dumping Berkeley DB version 1.86 hash databases. [#4418]</li>
<li>Reduce the number of calls setting the errno value, to improve performance on Windows/NT in MT environments. [#4432]</li>
<li>Fix for Darwin (and probably some other) OS's that were getting 'yes' or other garbage in generated makefiles in place of a shared library name. [#4453]</li>
<li>C++: Remove inlining for constructor of tmpString internal class. This fixes warnings on Solaris profiling builds. [#4473]</li>
<li>DB now restarts system calls that are interrupted by signals. [#4480]</li>
<li>Fixed warnings for compiling Java native code on Solaris and OSF/1. [#4571]</li>
<li>Added better configuration for Java on Tru64 (OSF/1), Solaris,</li>
<li> Java files are now built as jar files. Berkeley DB classes are put into db.jar (which is an installed file on UNIX) and examples are put into dbexamples.jar. The classes directory is now a subdirectory of the build directory, rather than in java/classes. [#4575]</li>
<li>Support Cygwin installation process. [#4611]</li>
<li>Correct the Java secondary_key_create method signature. [#4777]</li>
<li>Export additional Berkeley DB interfaces on Windows to support application-specific logging and recovery. [#4827]</li>
<li>Always complain when using version 2.96 of the gcc compiler. [#4878]</li>
<li>Add compile and load-time flags to configure for threads on UnixWare and OpenUNIX. [#4552] [#4950]</li>
