MySQL est passé en version 4.0.16 dont voici le changelog :
- Write memory allocation information to error log when doing `mysqladmin debug'. This only works on system that support the `mallinfo()' call (like newer Linux systems).
- Added the following new server variables to allow more precise memory allocation: `range_alloc_block_size', `query_alloc_block_size', `query_prealloc_size', `transaction_alloc_block_size', and `transaction_prealloc_size'.
- `mysqlbinlog' now reads options files. To make this work one must now specify `--read-from-remote-server' when reading binary logs from a MySQL server. (Note that using a remote server is deprecated and may disappear in future `mysqlbinlog' versions).
- Block `SIGPIPE' also for non-threaded programs. The blocking is moved from `mysql_init()' to `mysql_server_init()', which is automatically called on the first call to `mysql_init()'.
- Added `--libs_r' and `--include' options to `mysql_config'.
- New ``>' prompt for `mysql'. This prompt is similar to the `'>' and `">' prompts, but indicates that an identifier quoted with backticks was begun on an earlier line and the closing backtick has not yet been seen.
- Updated `mysql_install_db' to be able to use the local machine's IP address instead of the host name when building the initial grant tables if `skip-name-resolve' has been specified in `my.cnf'. Using this option can be helpful on FreeBSD to avoid thread-safety problems with the FreeBSD resolver libraries. (Thanks to Jeremy Zawodny for the patch)
- A documentation change: added a note that when backing up a slave, one needs to backup the `master.info' and `relay-log.info' files, and the `SQL-LOAD*' files (which are in the `slave-load-tmpdir' directory, which defaults to `tmpdir' if unset). All these files will be needed when the slave resumes replication after you restore the slave's data.
