MySQL 4.1.15 released.

MySQL 4.1.15, a new version of the popular Open Source/Free Software Database Management System has been released. It is now available in source and binary form for a number of platforms from our download pages at http://dev.mysql.com/downloads/ and mirror sites.

This is a bug fix release for the current production series.

Changes in release 4.1.15:

  • The limit of 255 characters on the input buffer for mysql on Windows has been lifted. The exact limit depends on what the system allows, but can be up to 64K characters. A typical limit is 16K characters.
  • Added the myisam_stats_method, which controls whether NULL values in indexes are considered the same or different when collecting statistics for MyISAM tables. This influences the query optimizer as described in Section 7.4.7, "MyISAM Index Statistics Collection."
  • Better detection of connection timeout for replication servers on Windows allows elimination of extraneous Lost connection errors in the error log.
  • When using IF NOT EXISTS with CREATE DATABASE or CREATE TABLE, a warning now is generated if the database or table already exists.
  • A new command line argument was added to mysqld to ignore client character set information sent during handshake, and use server side settings instead, to reproduce 4.0 behaviour
