I’m sure you are all aware of the ongoing efforts spent on the documentation (with no small amount of corrections from our very helpful community), and that you made it your habit to re-read the full 400 or so pages on the second weekend of each month, but still: it is worth pointing out that there are not only additions for all the new features, there are also clarifications. Here are just a few select pointers you could choose to start your next doc journey with:

• looking behind the curtain: the cluster specification
• designing actor systems: blocking with care
• top-level guardians explained
• how to configure multiple actor systems
• a word on dead letters
• supervision and lifecycle clarifications
• Akka use cases
• several updates to the remoting docs, for Java as well as Scala
• status update for durable mailboxes

It is always a good idea to read the core actors documentation from time to time, available for Java and Scala. And of course please check out the migration guide.
