 TODO:
-* Rethink documentation flow and rewrite?
 * Port connection portion to other DBMS?  Genericize the module?  Start with 
   PostgreSQL. (provider mechanism, and libDBI)
-* merge server config into vh config
 * does determining table name in massvirtual mode upon every request
   cause performance degradation?  If so fix.
 * LogSQLRotateLogs directive with daily/monthly/weekly/etc.
 * new format char: IP as bigint? ( not w/ ipV6 )
 * socket-based middleman daemon with configurable conns, or connect/disconnect.
 * ignore by cookie
+* tools to import logs into SQL
+* Directive to yes/no create ancillary tables (or just access table)
+* break module into separate code files
+    separate DB implimentation into sub-modules via provider mechanism
+* add document building to Makefile.in
+* backport patch for apache 1.3
 
 CHANGES:
-1.90: ?
+1.91: 2003-12-23
+* Added checks for MySQL to autoconf
+* fixed merge code to work correctly.
+* Merged in 1.19b1 changes
+* Hostnames are now converted to lowercase in the mass-virtual naming section.
+  The loop that converts dots to underscores has been optimized as well.
+* New directive LogSQLTableType allows one to specify the kind of table that
+  the module makes during table creation (e.g. InnoDB, MyISAM).  Thanks to Jim
+  Turner for the suggestion and patch.  If your MySQL server does not support
+  the specified type, it will create a MyISAM table instead.
+* Directives can now be placed in the 'main' server config and will be
+  inherited by the virtual hosts.  This means a LOT less repetition: you only
+  specify the item once to have it inherited, but it can still be overridden
+  on a virtualhost level.  These can be specified in this manner:
+
+                LogSQLTransferLogTable
+                LogSQLTransferLogFormat
+                LogSQLPreserveFile
+                LogSQLNotesLogTable
+                LogSQLHeadersInLogTable
+                LogSQLHeadersOutLogTable
+                LogSQLCookieLogTable
+                LogSQLRemhostIgnore
+                LogSQLRequestIgnore

+                LogSQLWhichCookies
+                LogSQLWhichCookie
+
+1.90: 2003-12-22
 * updated code to compile under apache 2.0
 * rewrote and consolidate configuration handler routines
 * made all functions static.
 * made delayed insert configurable, instead of compile time
+* moved to my autoconfigure support
 
 1.18:
 * Delayed inserts (a MySQL extension) are now available at compile-time.
