Sequel 3.13.0 was released today! Full release notes are available, but here are some highlights:

• Sequel now supports Ruby 1.9.2pre3.
• Sequel now supports prepared transactions/2-phase commit.
• Sequel now supports customizable transaction isolation levels.
• Sequel now ships with built-in plugins for serializing/deserializing model datasets and instances to/from JSON and XML.
• Sequel now ships with built-in tree and list plugins.

Not much is currently planned for 3.14.0. As always, I’ll certainly fix bugs and consider feature requests submitted from the community.
