TAO Testing
TAO opens the 56.15 line with a database index while patching a bad migration on three branches.
A side-by-side editorial comparison of Open edX and Opencast — release velocity, themes, recent moves, and the top alternatives to consider.
Open edX is rebuilding course authoring around reusable Libraries.
The Ulmo release in January 2026 lets authors build complete course structures inside Libraries and sync them into multiple courses with visual diff before apply. That extends the Teak (mid-2025) Libraries work and the Sumac (Feb 2025) Content Libraries beta. Content Tagging (March 2025) sits underneath as the indexing layer making reuse navigable.
Opencast maintains three release lines in parallel, and its feed shows only version numbers.
Opencast, the university lecture-capture platform, ships regular point releases on three supported lines: 20.x (current), 19.x and 18.x. Every feed entry is a version tag that links to external release notes, so the specific changes are not visible here. The steady pattern of 20.x and 19.x releases landing within a day of each other points to coordinated backporting.

Open edX has spent the last four named releases — Sumac, Teak, Ulmo, with Content Tagging in between — turning Libraries into the first-class authoring primitive instead of treating each course as a silo. The product is moving from one-course-at-a-time authoring toward a content-reuse model that resembles how textbook publishers and large training orgs actually want to work.
The next release will likely close more of the Libraries-to-course gap: branching/versioning of library content, finer-grained sync controls, and probably AI-assisted authoring on top of the tagged-and-libraried content base.
Opencast, the university lecture-capture platform, ships regular point releases on three supported lines: 20.x (current), 19.x and 18.x. Every feed entry is a version tag that links to external release notes, so the specific changes are not visible here. The steady pattern of 20.x and 19.x releases landing within a day of each other points to coordinated backporting.
The cadence is roughly monthly per line, with 18.x releases getting rarer, which fits a project that supports older majors for a set window and then retires them. Because the feed has no changelog content, it doesn't show which features are moving.
Expect 20.5 and 19.10 around late October and 18.x to wind down; what they will contain can't be read from this feed.
