What is Zenler?

Zenler publishes version-numbered fix lists with the occasional real feature buried at the bottom.

Every entry is a build stamp wrapping a long list of bug fixes, and the actual releases sit at the end of those lists. Reading past the fixes: the Community gained member search, username-scoped post search, language support, and a rule requiring a profile picture and bio before entry; billing gained self-serve plan changes and cancellation, invoice downloads for admins, retained access through the paid period, and instant refunds inside 30 days; reporting gained a student-wise quiz detail report with export. Gamification appears as a single line with no description. The feed stops at April 2026.

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.

Zenler publishes version-numbered fix lists with the occasional real feature buried at the bottom.

◆ Current state

Every entry is a build stamp wrapping a long list of bug fixes, and the actual releases sit at the end of those lists. Reading past the fixes: the Community gained member search, username-scoped post search, language support, and a rule requiring a profile picture and bio before entry; billing gained self-serve plan changes and cancellation, invoice downloads for admins, retained access through the paid period, and instant refunds inside 30 days; reporting gained a student-wise quiz detail report with export. Gamification appears as a single line with no description. The feed stops at April 2026.

◆ Where it's heading

The ratio tells the story — the bulk of each release is repair on funnels, emails, reports, cloning, and checkout, which is what a broad course-and-marketing platform costs to keep running. Where new work does land it clusters in two places: the Community, which is being built into a real social surface rather than a comment thread, and self-serve billing, which removes support from the cancel-and-refund path. The double opt-in rework touches both by making enrollment wait for verified email.

◆ Prediction

Expect Community to keep accumulating the moderation and discovery features that make it usable at size, since search and mandatory profiles are the first two. The unexplained gamification line is the one thing the entries cannot support a read on.

T5.0

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.
