ClassroomIO vs TAO Testing: at a glance
What is ClassroomIO?
Pre-1.0 open-source LMS in a security-hardening sprint after a wave of disclosed CVEs.
ClassroomIO is an early-stage (0.2.x) open-source learning platform. The recent release log is dominated by security work: stored XSS via SVG upload, email-verification bypass vectors, and a full migration of client-side database calls to server-side authenticated endpoints with role-based filtering — three security releases inside a single week in early December 2025. The January 2026 patch is an unrelated content-save data-loss bug.
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.

0.0EDTECH
Pre-1.0 open-source LMS in a security-hardening sprint after a wave of disclosed CVEs.
◆ Current state
ClassroomIO is an early-stage (0.2.x) open-source learning platform. The recent release log is dominated by security work: stored XSS via SVG upload, email-verification bypass vectors, and a full migration of client-side database calls to server-side authenticated endpoints with role-based filtering — three security releases inside a single week in early December 2025. The January 2026 patch is an unrelated content-save data-loss bug.
◆ Where it's heading
The product has just walked through a security maturity gate. Moving from client-side DB access to a server-side API with auth middleware is a foundational change, not a cleanup — it implies the previous architecture wasn't safe to grow on. After it, the cadence drops to small bug fixes, which fits a team catching its breath after structural rework. There's no visible product-direction work yet (no new features, no AI, no integrations).
◆ Prediction
Once the team is confident in the new server-side architecture, expect the next visible work to swing back to features — likely course-builder or learner-flow improvements that the prior architecture made hard. Another security release is possible but less likely given how comprehensive 0.2.8 was.
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.
