Pondering 2.1 to 3.0

[Richard Rodseth]

Congrats on the release of 3.0!

I have an Akka/Spray/Slick app. The other night I switched Slick versions (in a branch) and if I remember rightly the package change was the only source change I needed to make.

Is it fair to say that it's pretty safe to upgrade, and then incrementally introduce

- use of new config and default pool

- use of new APIs and database closing

?

Does the Database closing go in a shutdown hook? 

Any performance improvements *without* using the new APIs?

I currently have a routed DbActor (no asks, just tells and response messages) and BoneCp config.
