Open edX vs TAO Testing: at a glance
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 follows its lockdown browser release with a version-gate fix within days.
TAO's core reached 56.16.4 on November 13. 56.16.3 lets admins set a minimum lockdown browser version, three days after 56.16.0 added lockdown browser delivery, and restores another deleted language string; 56.16.4 syncs Crowdin translations. The older 56.13.1 branch got a backport of Japanese translations in 56.13.1.4.

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.
TAO Testing
5.0EDTECH
TAO follows its lockdown browser release with a version-gate fix within days.
◆ Current state
TAO's core reached 56.16.4 on November 13. 56.16.3 lets admins set a minimum lockdown browser version, three days after 56.16.0 added lockdown browser delivery, and restores another deleted language string; 56.16.4 syncs Crowdin translations. The older 56.13.1 branch got a backport of Japanese translations in 56.13.1.4.
◆ Where it's heading
Secure test delivery is the active feature track: lockdown browser support shipped and is already being tightened so schools can require a current client. Around it, TAO keeps maintaining several older patch branches with backports, which points to institutions that upgrade slowly.
◆ Prediction
Expect further 56.16 patches on lockdown browser configuration and more backports to older branches; a 56.17 feature release is not signaled in these notes.
