MySQL Reference Manual for version 4.0.18.
C.4.54 Changes in release 3.23.7 (10 Dec 1999)
-
Fixed workaround under Linux to avoid problems with
pthread_mutex_timedwait(),
which is used with INSERT DELAYED. See section 2.6.1 Linux Notes.
-
Fixed that one will get a 'disk full' error message if one gets disk full
when doing sorting (instead of waiting until we got more disk space).

Fixed a bug in
MyISAM with keys > 250 characters.
-
In
MyISAM one can now do an INSERT at the same time as other
threads are reading from the table.

READ lock after a certain number of WRITE locks.
-
Inverted flag
delay_key_write on show variables.
-
Renamed
concurrency variable to thread_concurrency.
-
The following functions are now multi-byte-safe:
LOCATE(substr,str), POSITION(substr IN str),
LOCATE(substr,str,pos), INSTR(str,substr),
LEFT(str,len), RIGHT(str,len),
SUBSTRING(str,pos,len), SUBSTRING(str FROM pos FOR len),
MID(str,pos,len), SUBSTRING(str,pos), SUBSTRING(str
FROM pos), SUBSTRING_INDEX(str,delim,count), RTRIM(str),
TRIM([[BOTH | TRAILING] [remstr] FROM] str),
REPLACE(str,from_str,to_str), REVERSE(str),
INSERT(str,pos,len,newstr), LCASE(str), LOWER(str),
UCASE(str) and UPPER(str); patch by Wei He.
