I just pushed an update to my SQLite wrapper FMDB and have tagged it as version 2.0. Hurray for round numbers!
So what's new?
FMDB is Automatic Reference Counting (ARC) friendly now. It'll detect if your project is using ARC or not, and do the right thing with retain and release.
There's a new class called FMDatabaseQueue. If you're wanting to use FMDB across multiple threads, then you'll want to use this guy. It's a great block based API that is pretty darn easy to use.
You can make custom sqlite functions as well, using blocks. This is awesome if you want to do something like UTTypeConformsTo() at the query level.
And finally the addition of named save points with a block based API.
