Questions on the release? Email

Appropriate bug fixes (no new features) are being merged from trunk to the 2.5.x Maintenance Branch. At periodic intervals, Maintenance Releases are created from the Maintenance Branch. So you are encouraged to treat the most recent Sakai 2.5 Maintenance Release as the recommended version of Sakai 2.5.

Jira Information

Some short-cuts to relevant views in Jira for Sakai 2.5-related information:

Sakai 2.5.x Maintenance Branch

Only bug fixes are being merged to the Sakai 2.5.x Maintenance Branch, no new features are being introduced. This branch will form the basis for #Sakai 2.5 Maintenance Releases.

Sakai 2.5 Maintenance Releases

Maintenance releases will be tagged from the 2.5.x Maintenance Branch at periodic intervals for up to two years after the initial release of Sakai 2.5.0 (or longer, if there is sufficient community interest and resources.) The Maintenance Releases will include bug fixes merged from the Maintenance Branch for a selected subset of components, rather than all available fixes in the Maintenance Branch at that point in time the tag. Maintenance Releases will be subjected to a short period of focused QA, which will target the areas of change in the code. Only a selected subset of components is included in order to keep QA manageable and the interval between releases short. As a result, the Maintenance Releases will lag the Maintenance Branch in terms of completeness of fixes, however, this trade-off is important in enabling a high-frequency of well-tested Maintenance Releases.

Post-2.5 Feature Branches

Feature Branches are intended to provide early access to new functionality or enhancements intended for the next major release. This enables interested organizations to take advantage of the new functionality without waiting for the next release; however, the feature branches have generally only been subjected to limited QA by the project team itself, and they are typically offered on an as-is basis. (General information on Features Branches....)

For participating projects, the Feature Branch code is located in the post-2.5 branch in a project's SVN repository. The project may also provide tags, such as post-2.5-a, post-2.5-b, ..., to help identify reliable starting points from which to adopt the code.

For the Project Teams, part of the drive for this early delivery of functionality is to meet the needs of a team member's local Sakai implementation, hence, the functionality has typically been subjected to a good deal of testing at their institution and has generally been tested for production deployment. The Project Teams do not necessarily have additional time to incorporate others' design suggestions for the 2.6 release, however, they certainly will welcome bug reports and attempt to address them before the 2.6 release, and consider suggestions for future releases. Some Project Teams may also choose to continue supporting the post-2.5 branches with bug fixes even after 2.6 is released, but it is not guaranteed.

Projects tentatively planning to offer a post-2.5 Feature Branch include:

  • site-manage
    • SAK-12868 - Getting issue details... STATUS : site templating
  • Email Service
    • SAK-12581 - Getting issue details... STATUS : Add attachment support to Email service
  • Portal
  • Tests & Quizzes (a.k.a. Samigo)
    • Incorporating UCT's work on group-scoped tests and improvements to statistics reporting ( SAK-12065 - Getting issue details... STATUS ).
  • Resources? and/or Content Hosting Service?

Pre-Release Information


A few goals have been defined to aid in channeling the community energy to produce a high quality release. We'll be using language to aid in describing the transition of the software as it approaches readiness. To make the progression from beta to release candidate, the aim is the resolution of outstanding blocker and critical bugs reported.

  • Elimination of all outstanding Blocker and Critical bugs for 2.5 (n=64).
  • Acceptable Performance testing on mysql and oracle databases for Assignments, Resources, Forums, GB & T&Q. What is acceptable? At this point in time, no degradation from performance experienced in 2.4
  • High degree of verification (85%) of resolved JIRA bugs
  • Confirmed functional testing on all tools.
  • Positive feedback from sites running a tagged version of off branch.

Tool Promotions/Retirements

With each Sakai release Contrib and Provisional projects can be nominated evaluated for promotion to Provisional and Core status, respectivley. Projects that the community feels are no longer of importance, or which have been replaced by other projects, may be retired from Core or Provisional status to Contrib. Follow the Discussion links below to comment in the discussion on whether or not to promote the tool. (See Criteria for Provisional Status for guidelines on the requirements a tool needs to meet for Provisional Status.)

Share Your Experiences
