Why is EventBus annotated with @Beta?

[Glenview Jeff]

I excitedly read about Guava's support of EventBus but when I started to try it out, I saw in the Javadoc that it's annotated as @Beta, and as such that it may be removed in future releases.  Guava's website doesn't appear to mention this.

Is this something I need to be concerned about?  Is it really beta?  Is anyone using it in production code?

It's almost certainly being used in production code, and it's definitely @Beta.  We have a lot of feature requests for it, some of which are mutually exclusive, or at least difficult to provide simultaneously.

I think it's popular enough that it won't get removed (unless we provide something new and better), but its semantics might change, which is why it's @Beta.

Take a look at the @Beta Javadoc and at my answer to a StackOverflow question here for some information on what @Beta means.

In a nutshell, we just felt that @NotApiFrozen was too awkward, but that's exactly what it means.

I'm glad you guys take API design so seriously as to document this.  I've used several libraries already where I had to modify a ton of code because of API changes during upgrades.  This means you Roboguice.  :)

And incidentally, I plan on replacing my code that uses Roboguice's event handler with Guava since there's no good reason it should be Android-specific.

Apparently, this code is still @Beta and IDE warns that am using an unstable dependency

At this point we are not actively developing EventBus. There are several more modern frameworks for event-driven or reactive programming, including RxJava among others.
