Version 4.4.16 of Berkeley DB

Release Notes: This release introduces a number of new HA (high availability) features. These include in-memory replication, client-to-client replication, delayed client synchronization, synchronization throttling, and master election speed-ups. In addition, it adds a hot backup utility, online Btree compaction, online Btree disk space reclamation, online abandoned lock removal, automated recovery serialization, and a new Transactional Application Developer's Guide.

Release Notes: The first 5.3 release came out a few month ago. One of the main highlights was support for the Android platform. 5.3.21 is the second release. This is mainly a bugfix release, but it does include one feature which is potentially very interesting, support for Oracle JDK7.

Release Notes: New features include an online backup command for SQL, VACUUM (which does not require the database to be quiescent), encryption, BFILE, ADO.NET, iOS/iPhone/iPad support (in addition to existing support for Android), a new command line tool called "db_replicate" which will turn non-HA applications into HA/replicated applications with no new code, performance improvements, and lots of other features.

Release Notes: Increased Performance: improved concurrency for multi-threaded applications on SMP systems. A new db_sql tool: automatic generation of Berkeley DB application code from SQL for faster development and migration. New APIs: support for C#/.NET and the C++ Standard Template Library (STL).

Release Notes: The lock manager may now be partitioned, improving performance on some SMP and CMP systems. Optional pre-zero log files. Replications across different endian CPUs. Replication can manage the master node via leases.

Release Notes: Non-stop upgrades for replicated systems: customers can upgrade/patch the database without taking the entire system down. Multi-version concurrency control (MVCC) allows read transactions to proceed without being blocked by write transactions, therefore improving concurrency and performance. Replication framework is a pre-built, out of the box framework that makes it faster and easier for developers to build replicated apps.
