What is Perusall?
Perusall refreshes its UI to absorb a year of expanded assignment types and instructor controls.
Perusall is a social-learning platform centered on collaborative annotation of course materials. The January 2026 release is a UI refresh — a single simplified sidebar, reorganized Settings, more flexible grouping — that consolidates the navigation around the broader feature set built up over 2024 and 2025. That earlier work pushed Perusall well beyond annotation: peer review went from new in mid-2024 to substantially refined a year later, with new assignment types (Fishbowl, instructor review), differentiated assignments, granular TA permissions, and reusable scoring templates.
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.

Perusall

Perusall refreshes its UI to absorb a year of expanded assignment types and instructor controls.
◆ Current state
Perusall is a social-learning platform centered on collaborative annotation of course materials. The January 2026 release is a UI refresh — a single simplified sidebar, reorganized Settings, more flexible grouping — that consolidates the navigation around the broader feature set built up over 2024 and 2025. That earlier work pushed Perusall well beyond annotation: peer review went from new in mid-2024 to substantially refined a year later, with new assignment types (Fishbowl, instructor review), differentiated assignments, granular TA permissions, and reusable scoring templates.
◆ Where it's heading
The product is evolving from an annotation tool into a course-assignment platform with instructor operations baked in. Peer review was the wedge in 2024; 2025 widened the assignment catalogue and added the kinds of controls (TA permissions, reusable rubrics, late-submission handling) instructors need to actually run those assignments at scale. The 2026 UI refresh signals consolidation — the team is making the broader catalogue discoverable rather than adding new features for now.
◆ Prediction
Based on the visible cadence — annual major batches around the start of the academic year — the next observable move is likely further refinement of peer review workflow flexibility, since that's been the most consistently iterated surface across the input entries.
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.
