This plan describes the work for Riena 4.0.0, which is planned for Jun 2012 (Juno release train). Riena 4.0. is a major release. One of the targets is to make Riena ready to run on top of e4. The major objective for Riena 4.0. to provide Riena on top of e4 but still allow it to run on Eclipse 3.x Major API changes in 4.0 are outlined here. Riena plans on delivering milestone on the following schedule: (API Freeze) (Feature Freeze) Riena's target environments are: Eclipse-based RCP/3.8 Applications Eclipse-based RAP(Web) Applications Equinox-Based Runtimes (e.g. Equinox servers) Riena uses Eclipse internationalization support whereever it applies for its own components Riena's APIs are currently stable. We intend to improve and break few APIs on the way to the 4.0 release. API are considered all exported packages that are not marked as x-internal:=true in their Export-Package declaration.
