mysql_fetch_length fixed for embedded library. Now data length is stored
before the data. Pointers in row still points to the data so you have to
get *(uint*)(data_ptr - sizeof(uint)) to get data length

Fixed some mess with STDCALL in function's declarations

error handling fixed
fetch_lengths made to work differently in embedded and client cases

Including client code into embedded library
fixes

Including client code into embedded library

Code trimming (fixes of comments etc)

Updated VC++ files

including client code into embedded server
code to guess what library to use added
net_field_length moved to pack.c

client capabilities included into libmysqld
some API methods became "virtual"
lots of duplicated code removed

IMHO all the above made library's code way more pleasant to look at, didn't it?

bmove_allign -> bmove_align
Added OLAP function ROLLUP
Split mysql_fix_privilege_tables to a script and a .sql data file
Added new (MEMROOT*) functions to avoid calling current_thd() when creating some common objects.
Added table_alias_charset, for easier --lower-case-table-name handling
Better SQL_MODE handling (Setting complex options also sets sub options)
New (faster) assembler string functions for x86

Novell patches

Fixed a few typos from last patch

Portability fixes
Added new client function: mysql_get_server_version()
New server help code (From Victor Vagin)
Fixed wrong usage of binary()
Disabled RTREE usage for now.

MIN(key_column) could in some cases return NULL on a column with NULL and other values.
MIN(key_column) and MAX(key_column) could in some cases return wrong values when used in OUTER JOIN.

Don't use new password format if mysql.user has old format
tables_priv was not reset on FLUSH PRIVILEGES if tables_priv was empty
Portability fixes for Windows

Warning handling and initial prepared statement handling (last not complete yet)
Changed a lot of functions that returned 0/1 to my_bool type.
GRANT handling now uses read/write locks instead of mutex
Change basic net functions to use THD instead of NET
(needed for 4.1 protocol)
Use my_sprintf instead of sprintf() + strlen()
Added alloc_query() to be able to chare query initialization code with
prepared statements.
Cleanup handling of SHOW COUNT(*) WARNINGS and SELECT LAST_INSERT_ID()

Note that the following test fails (will be fixed ASAP):
sub_select, union, rpl_rotate_logs and rpl_mystery22

Made a some new buffers thread specific and changeable.
Resize of key_buffer.
AUTO_COMMIT -> AUTOCOMMIT
Fixed mutex bug in DROP DATABASE
Fixed bug when using auto_increment as second part of a key where first part could include NULL.
Split handler->extra() to extra() and extra_opt() to be able to support thread specific buffers.
Don't write message to error log when slave reconnects becasue of timeout.
Fixed possible update problem when using DELETE/UPDATE on small tables
(In some cases we used index even if table scanning would be better)
A lot of minior code cleanups

Remove not used flag CLIENT_CHANGE_USER

Fixed memory leak on shutdown (Affects the embedded version & MyODBC)

Speed up column-completion in 'mysql'
Don't use ISAM if HAVE_ISAM is not defined
A lot of fixes for the embedded version.  All libraries are now included in libmysqld.a
Changed arguments to convert_dirname() to make it more general.
Renamed files in the 'merge' directory to all use a common prefix.
Don't compile both assembler and C functions on x86

Fix that compressed packets and normal packets looks indentical before calling net_real_write()
(Needed for query cache)
Optimize IS NULL handling

Fixes for embedded server
Made key_cache more configurable
Fixed that one can change key blocksize in MyISAM
A lot of optimizations to make MyISAM slightly faster

Fixes for embedded libary and openssl
