Handly is breaking new ground with the 0.5 release, a true "2.0" version in spirit. This release, scheduled to coincide with Eclipse Neon, introduces an entirely new design that gives the implementor of a Handly-based model complete control over the model API. Among other things, this should make it possible to use Handly for (re-)implementing handle-based models where the model API is a given, just as in the case of a preexisting model API that needs to be preserved for backward compatibility. Many of the core APIs have been revised in this release to make Handly even more flexible and robust.
There is no declared API in this release as both the API and the API policy may still evolve.
That being said, this release is heavily focused on API quality and takes a significant step further towards finalizing core Handly APIs.
Due to the API rework involved, this release introduces a number of breaking changes and is expected to be more disruptive than previous releases. We'll guide early adopters through necessary migration steps.
All discussion happens on open channels of developer mailing list , adopter forum  and bugzilla . The project lead's blog posts on topics surrounding Handly  are syndicated to Planet Eclipse.
The project's community was promptly informed about the scope of ensuing changes in this release . To provide current adopters with an opportunity to give it an early try, leave feedback or raise concerns, a milestone build (corresponding to an attempt at API freeze towards this release) was made available .
The first significant contribution to the project by a non-committer made its way into this release . It was kindly provided by Ondrej Ilcik, head of IDE development at Codasip. Codasip Studio is one of the earliest adopters of Handly, and Ondrej has been so kind as to share a great success story  besides being vocal on the developer mailing list and adopter forum. Thanks a lot for all your help, Ondrej!
Vlad Dumitrescu, the project lead of erlide, was actively participating in discussions on the developer mailing list about the entirely new design introduced in this release (his earlier feedback helped inspire the new design), and also contributed great ideas about restructuring the project's web page to make it more readable . Thank you very much, Vlad!
