Make InnoDB to restore old active_index value after a table scan: MySQL may assume that a scan does NOT change active_index; this partially fixes bug 241 of UPDATE ... ORDER BY ... but it still remains that MySQL actually ignores the ORDER BY for both MyISAM and InnoDB tables
log0recv.c:
  Use fflush to make sure report of a corrupt log record is printed to .err log before mysqld crashes

  Do not allow InnoDB to cache result set in HANDLER because user can use PREV and NEXT and scroll the cursor

  Allow HANDLER PREV and NEXT also after positioning the cursor with a unique search on the primary key

  Better fix for the ON DELETE SET NULL problem

  Fix bug: we did not allow ON DELETE SET NULL to modify the same table where the delete was made; we can allow it because that cannot produce infinite loops cascaded operations

  Fix crash in HANDLER PREV or NEXT if the cursor was positioned using a unique search condition on the primary key: in that case InnoDB does NOT store the cursor position for later fetch prev or next

  Merge InnoDB-4.0.13; DROP FOREIGN KEY now works

Added logging of warnings for failed connections with ssl.
Fixed bug in symbolic link handling on Windows

   (bug #223)
 - Added more detailed info about how to set up replication

   (bug #264)

 - added Dummy file Docs/manual_toc.html to make "make dist" happy if the
   real manual.texi has not been copied into Docs/ (which would make sure
   a "real" manual_toc.html would be created
 - fixed symlinking in the bdb subdirectory (docs are not included anyway)
 - added dist-hook to Makefile.am to remove superfluous SCCS directories
   from the source distribution

 - adjusted LSB run levels to be identical as on Red Hat (2-5)

   libraries always ended up in "dir..", even though they were not supposed
   to be installed anyway (they are only required at link time). Fixed it by
   replacing libs_LIBRARIES with noinst_LIBRARIES for all InnoDB Makefile.am 
   files and by removing "libsdir = " from innobase/include/Makefile.i .

   in the sample configuration files
 - reworked the replication options and comments a bit
 - added option "skip-networking" (commented out by default) to the
   sample configuration files (enhancement request from bug report #234)

   to run the script even if mysqld is not up and running on upgrade

(3.23 master, 4.0 slave. 
Slave loss temp tables everytime FLUSH LOGS on master). 
This fix is less bad than the bug, it will cause a problem only maybe
if the master dies the hard way (I say maybe because I could not
cause a problem, and I don't see how it could happen).

   if it's built with debugging enabled or not stripped (save disk
   space)

because of writing problems (such message would have been useful during a recent
support task).

  Fix bug number 224: do not call ha_report_binlog_offset_and_commit() when a MyISAM table is updated; this also makes CREATE TABLE not to commit an InnoDB transaction, even when binlogging is enabled
