Hi!
I've noticed that Pelles C uses SQLite 2.8.x for it's databases. Will future versions use SQLite 3.3.x?
Probably. The 2.x series is still "supported", and since the API in 3.x is different (I think), it's not high priority at the moment...
3.3.x API is not much different but engine and storage format are much improved.
I agree that this is low priority.
