You will find the current OJS development roadmap below. Please note that these dates are not fixed. Active OJS development follows three development branches: a 'stable' 2.4.x line which includes mainly bugfixes and will be an easy, painless upgrade for existing users of the current release (and who do not need much in the way of new features); a 'development' line (no releases currently available), which will become the next stable branch; and the 'master' git repository, which includes large-scale changes in the underlying codebase as well as many new features, and is not yet released for production use.
While we do attempt to list all bugs tracked against a given release, quite often a bug report against one release will be ported to another (this is especially the case with 2.3.x bugfixes into the master branch; less so with 2.4 enhancements into the stable branch). This is also the case with some bugs tracked against other applications such as Open Conference Systems. You are encouraged to browse our Bugzilla database fully. Bug entries are typically filed against the version in which the new code is expected to be released.
Milestone 3.0 (Q1 2014)
OJS 3.0a and 3.0b will be used to perform UI/UX testing, acceptance testing, and other assessments, leading to a 3.0 release that will be remarkably different from the long-standing 2.x line. It will likely be launched without the full breadth of the 2.x feature set, with the remainder to be re-introduced in follow-up releases. Other functional enhancements are currently under consideration for inclusion in this release.

Milestone 2.4.x (Ad-hoc scheduling)
Releases of OJS in the 2.4.x line will be made when necessary (e.g. based on security issues) or when desired (e.g. when enough minor fixes accumulate that the community will find them broadly useful). These releases are very limited in change scope to keep the testing and release processes to a minimum; for example, no translation updates are allowed for 2.4.x releases. The most important changes in each 2.4.x release are posted on the Recommended Patches page.
The OJS 2.4.x line was flagged "stable" (taking on this designation from the previous 2.3.x line) as of the OJS 2.4.2 release. OJS 2.4.3 is the next scheduled OJS 2.4.x release, currently planned for September 2013.
Milestone 2.4 (Q3 2012)
This release will include large-scale revamping of the PKP codebase, including the further abstraction of common code from all applications into the PKP WAL that began with the 2.3.0 line of releases; modularization of the remaining OJS codebase (so that components can be better mixed and matched in each application); and further overall code refinements. This release will set the stage for large-scale porting of OMP functionality (user interface improvements; flexible roles; etc.) in the subsequent 3.0 release.
Milestone 2.3.x (Ad-hoc scheduling)
Further releases in the 2.3.x line are not expected, but may be released should critical issues arise such as security vulnerabilities. The most important changes in each 2.3.x release are posted on the Recommended Patches page.
