What is Open edX?

Open edX closes a stored-script hole in course certificates on both supported release lines

Open edX's visible stream is release-branch commits, and every recent one is corrective. The October fix stops course authors from planting script in certificate pages through an Advanced Setting that was merged into the certificate context unescaped, and it landed on verawood and ulmo within the same minute. July's entries closed an authorization gap on the course-team endpoint the same way, one fix per branch.

What is TAO Testing?

TAO adds spell checking to its item editor in a run of 56.15 patches.

TAO's core shipped six 56.15 patch releases between November 6 and 9. The one user-facing change is WProofreader spell checking in the CKEditor used for authoring items; the rest are a PHP 8.5 date fix, release tooling, dependency bumps and a manifest update. A 56.14.8.2 backport kept the older branch supported.

Open edX closes a stored-script hole in course certificates on both supported release lines

◆ Current state

Open edX's visible stream is release-branch commits, and every recent one is corrective. The October fix stops course authors from planting script in certificate pages through an Advanced Setting that was merged into the certificate context unescaped, and it landed on verawood and ulmo within the same minute. July's entries closed an authorization gap on the course-team endpoint the same way, one fix per branch.

◆ Where it's heading

The work pattern is security backports to the two named branches operators actually run, not feature delivery. Fixes increasingly target trust boundaries inside a course: what an author or an enrolled learner can reach that they should not.

◆ Prediction

More paired backports to verawood and ulmo are the likeliest next entries; nothing in the feed points to a feature release.

T5.0

TAO adds spell checking to its item editor in a run of 56.15 patches.

◆ Current state

TAO's core shipped six 56.15 patch releases between November 6 and 9. The one user-facing change is WProofreader spell checking in the CKEditor used for authoring items; the rest are a PHP 8.5 date fix, release tooling, dependency bumps and a manifest update. A 56.14.8.2 backport kept the older branch supported.

◆ Where it's heading

TAO is in a maintenance rhythm on 56.15 while keeping older branches patched. Small authoring additions and PHP 8.5 readiness are the visible direction.

◆ Prediction

Expect more 56.15 patches and backports; the entries do not point to a larger feature release.
