dlz-0.4.3       Eigth release.  Updated patch for new version of Bind.
                Previous patches were for Bind 9.2.1.  This patch is for Bind
                9.2.2.  

                Fixed a small error in the DLZ core affecting Bind (named)
                startup.  If the DLZ driver failed to initialize, named would
                log the error but continue to startup anyway.  The DLZ driver
                would just not be used.  This has been changed so that if the
                DLZ driver does not initialize successfully, named will NOT
                startup.  This should make it easier to "know" that everthing
                worked at startup.
                
                Fixed a small problem with the build scripts.  The problem
                could cause the Berkeley DB driver build to fail if a special
                set of conditions were met.  The "search order" was changed so
                now the headers and libs for the Berkeley DB driver are in the
                search path before the other drivers.  On some systems this
                will cause multiple warning messages like the ones below to 
                appear.  This is ok.
                
cc1: warning: changing search order for system directory "/usr/include"
cc1: warning:   as it has already been specified as a non-system directory
                                 
                The PostgreSQL driver had dbcount declared as an unsigned int,
                but then did an evaluation that could potentially return a
                signed int.  The declaration of unsigned int has been changed
                to int.  This only effected compilation on some systems.
                
dlz-0.4.2       Seventh release.  In the process of migrating from bind-9.2.1
                to bind-9.2.2 the fixes that were supposed to be in this
                release didn't get migrated.  This release was pulled from
                the website.
                                
dlz-0.4.1       Sixth release.  Fixed a small error in the configure and make
                scripts.  If you attempted to build DLZ without Berkeley DB
                the make would fail in /bin/dlzbdb because the code was ifdef'd
                out, creating an empty *.o file.  The link process would not
                be able to find a main(argc, argv) in the *.o and the build
                would fail.  This has been fixed.
                
dlz-0.4.0       Fifth release.  A memory leak was discovered and fixed.  The
                DLZ core lost 2 bytes each time Bind responded to a DNS query.
                This bug was in the DLZ core, so it affected any system using
                DLZ no matter what driver you were using.  The memory leak was
                VERY slow requiring many thousands of queries before even a
                small change in memory was detected.  The DLZ core now seems
                to be rock solid and not leak any memory even after many
                thousands of queries.
                
                Added Berkeley DB driver.  Read the Berkeley DB docs for
                specifics of how to use this driver.
                
                Added DLZ Berkeley DB database utility.  This utility allows
                for basic operations on the Berkeley DB used by DLZ while
                Bind-dlz is running.  Read the Berkeley DB docs for specifics
                of how to use this utility.

dlz-0.3.0       Fourth release.  DLZ was too aggressive in "cleaning up" when a
                driver failed to start properly.  This resulted in named
                crashing instead of stopping gracefully when named was shutdown
                via "rndc stop".  This bug had no adverse effects while named
                was running.  This bug has been fixed.
                
                The SDLZ interface now searches for a "wild card" hostname if
                it has failed to find an exact hostname match.  I originally
                thought Bind would do this automatically with any database
                (as it does for it's internal DB).  I was mistaken.  All DLZ
                drivers built using the SDLZ interface now support
                "wild card", "*" hostname searches.
                
                Added MySQL driver.  Read the MySQL driver docs for specifics
                of how to use this driver and its limitations.
                
                Added File System driver.  Read the file system driver docs
                for specifics of how to use this driver.
                
dlz-0.2.1       Third release.  Updated patch for new version of Bind. Previous
                patches were for Bind 9.2.0.  This patch is for Bind 9.2.1.
                No new functionality in this release.  Only 1 minor code change
                in query.c was required to allow bind-dlz to operate properly.
                This change was required because of code added to Bind 9.2.1.

dlz-0.2.0       Second release.  Expanded the core code for DLZ and SDLZ APIs.
                Added capabilities to support zone transfers.  AXFR and IXFR
                queries are supported, but the response is always a full AXFR
                response.  Minor bug fixes and enhancements were made in
                various parts of the DLZ and SDLZ code.  Added extremely basic
                support for zone transfer to the dlz_stub driver.
                
                Major new feature is a complete PostgreSQL driver for the SDLZ
                API.  This driver allows for a great amount of flexibility
                in the way DNS data is stored in the database.  All
                capabilities (including zone transfer) of the (S)DLZ API are
                used and made available by this driver.

dlz-0.1.0       First release.  Includes core code for DLZ API and SDLZ API.
                This release of the API's support standard domain name
                resolution queries.  Dynamic DNS update, and zone transfer
                queries are not supported.  Also includes a very basic driver
                called dlz_stub.  The dlz_stub driver is useful for testing
                the DLZ and SDLZ code and demonstrating how to write a
                very simple SDLZ driver.
