Joomla! has great plans for the future of the project. Below is a generalised idea of the features desired for future releases and a highlight of in progress activity. When writing a revised roadmap we started by determining what we hoped to accomplish.

Timeframes of releases and semantic versions

With the development strategy published on 25 April 2014, one of the key features is maintaining long-term stability and backwards compatibility while also beginning to follow a semantic versioning approach to releases. The other aspect of timeframes was previously identified as a problem with the old release cycle. This ties in closely to the version numbers and release dates. By changing the releases to a somewhat standardised semantic version numbering and increasing the number of releases we will be able to stop the rush to include bugs and improvements in a release. Ideally the goal is to minimise the amount of items to be included in each release but also offer a more frequent release cycle.

Important to keep in mind: These releases are considered minor releases and none of them are to break backwards compatibility. Any features determined to break backwards compatibility will be moved to the next major release, presently Joomla! 4.x.

Please remember all dates are tentative and proposed focus for each release subject to modification.

Joomla!

Teams

Development for the Joomla! CMS is primarily lead by two teams within the Production Department.

CMS Release Team

The Release Team is responsible for quality assurance testing of the CMS and for planning, coordinating, and distributing all releases. The release lead for each minor release is a member of this team and acts as the primary decision maker when it comes to the release.

CMS Maintenance Team

The Maintenance Team is responsible for reviewing all proposed patches for the CMS, providing feedback on the proposed patch and making decisions regarding whether a patch is merged into the code base.

Joomla! 3.x

Joomla! 3.x is the currently supported major release series of the CMS.

Development Status
Current Release 3.8.0
Upcoming Release 3.9.0
Release Date of Series September 27, 2012

Joomla! 3.9

In preparation for Joomla! 4.0, Joomla! 3.9 will primarily be a release containing backports of API changes from the 4.0 development branch to help ease the transition to the next major release for the community. It is planned for 3.9 and 4.0 to release simultaneously.

Documentation Help Screens

The documentation help screens are based on a full major release series. As such, all of the help screens will require updates for Joomla! 4.0. In addition to the required updates, there is an idea proposal for a potential GSoC project to work on a new system to manage the screenshots; even if the project does not happen as part of GSoC the effort will continue otherwise.
