Looking at the number of changes and new features, MariaDB 5.3 is probably the biggest milestone release in MySQL history since 5.0:
- Fast sub queries and better optimizer
- Faster and better replication
- NoSQL extensions
- New important types (Microseconds)
MariaDB 5.3 is also important as MariaDB 5.5 is based on this. The merge of the code bases are already completed and as soon as our testing is complete (estimated to a couple of weeks) we will release MariaDB 5.5-beta.
A merry holiday and happy new year to you all!
