Release Notes: This release adds complete support for JDBC 4.0. Also new is support for sequences and identity columns, proper support for SQL locator-implemented large objects, database meta-data caching, JGroups channel multiplexing, improved failure handling, and improved distributable behavior.


Release Notes: This release fixes a number of bugs identified with the 1.1 release, including support for multi-column, cascading, and deferrable foreign keys; PostgreSQL BLOB (i.e. OID) synchronization; initialization error handling; identifier quoting; non-default CLOB charsets; and data source configuration export.


Release Notes: Java 1.5 is now required. Java 1.4 binaries are generated via Retrotranslator. Major new features in this release include a Dialect interface for defining vendor specific behavior, mbean interfaces for individual databases within a cluster, mbean methods for modifying HA-JDBC's configuration at runtime, an auto-activation scheduler, proactive failure detection, distributable locking to prevent simultaneous synchronization requests, support for XA environments, improved documentation, and many bugfixes.


Release Notes: This initial final release fixes a couple minor issues identified with 1.0-rc-5, including fixes to logging and JDK 1.4 source code compatibility.


Release Notes: This release candidate fixes several issues identified with 1.0-rc-3. Important changes include validating the persisted local cluster state during initialization to avoid startup problems when the cluster config changes and fixes to sync strategy initialization that prevented proper startup under JBoss.
