Liquibase 3.0.5 Released

The major focus of this release is performance improvements:

Startup time is significantly improved for larger databases
Preconditions now snapshot far less of the database
Running generateChangeLog on a test MySQL database with over 4000 tables went from crashing after an hour to completing in 30 seconds. Even an Oracle database with the same structure finished in a couple minutes.

If you are still seeing any unexpected performance problems, file a bug report

You can download 3.0.5 from http://liquibase.org/download and through the maven repository system once it gets mirrored through. If you have any questions or problems, visit the forums or bug tracker

Three bug fixes related to data type translations went into 3.0.5 which may cause issues for people that had been relying on incorrect behavior

MS SQLServer “DATE” columns are now translated to “DATE” rather than SMALLDATETIME
MySQL TIMESTAMP columns are now nullable if you do not specify that they should be not null
H2 and HSQL CLOB columns are now translated as CLOB rather than LONGVARCHAR

CORE-845 - “DATE” data type is deployed as “SMALLDATETIME” in SQL 2008
CORE-859 - Nullable TIMESTAMP columns in MySQL are not nullable.
CORE-1257 - Oracle: generateChangeLog exports a column of type “NUMBER” as “NUMBER(0,-127)”
CORE-1288 - H2 (and other) support for BLOB and CLOB is incorrect
CORE-1338 - Using apostrophe in changeset’s ID causes SQL error
CORE-1360 - Confirmation message of a custom change change is only printed if loglevel is debug
CORE-1364 - SQL Server incorrect INFORMATION_SCHEMA table case in native query
CORE-1365 - SQL Server: “Database ‘dbo’ does not exist” error
CORE-1401 - Unnecessary snapshot on liquibase update
CORE-1415 - Liquibase tables are not detected in oracle running in the SYSTEM schema
CORE-1426 - ORACLE: Check for existing tables is case sensitive
CORE-1429 - Random order of UniqueConstraint and ForeignKey drop statements
CORE-1459 - Maven updateSQL creates databasechangelog table, should only output SQL to do it
CORE-1462 - renameColumn with ‘text’ data type improperly trying to use ‘clob’ against MySql
CORE-1433 - Handle changes in column datatypes in diffChangeLog
CORE-1434 - Formatted Changelog format not parsing UTF8 .sql files with BOM
CORE-1453 - Multi-column foreign keys not snapshotted correctly
