* ⇒, →, ←
* because we don't want to show them in documentation snippets and
then it's complicated to avoid that when snippets are
located in src/test/scala in individual modules
* dont replace object `→` in FSM.scala and PersistentFSM.scala
* It uses ReplyEffect instead of Effect
* Unfortunatley the solution is a copy of the CommandHandler builder with
a few mechanical changes to the types and names.
* I tried to separate interface and implementation and use a shared implementation,
but it didn't work out because methods with such function parameters which only differ in
their type parameters can't be overloaded.
stuff moved to a new package. you wouldn't expect that in a point
release, but they put type aliases in place so Scala users wouldn't
notice. but the change is visible to Java code.
the upgrade is not strictly necessary, but it would be convenient
for the Scala 2.13 community build to have this merged, so I don't
have to maintain these changes in our Akka fork
* Remote deployment is not recommended and the section is duplicated
from classic remoting
* Move what's new lower down in prep for it becoming the main remoting
page but link to it for users are migration
* Make the AbstractBehavior builder mutable #26260
* Use mutable builder style in first sample, mention that fluent is an option
* A bit of rework of the Java builders:
* onAnyMessage added
* use the japi SAMs throughout in the APIs
* avoid wrapping the japi functions in Scala functions for the most common cases
* more Java test coverage
* Not just any exception
* Works on 2.11 as well as 2.12
* Complete the javadsl account examples in Persistence Typed docs
* corresponding style variations as in the scaladsl samples
* adding mutable state sample for Java (not interesting for Scala)
* cleanup the first example in Persistence Typed docs
* move ActorContext snip in Persistence Typed docs
* Effect.stash, Effect.thenUnstashAll
* unstash one at a time, and start with external stash if UnstashAll is in progress
* handle restarts
* handle PoisonPill
* fix PerformanceSpec, because now the internal stash is cleared if exception is thrown
* work with PoisonPill
