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 opens the 56.15 line with a database index while patching a bad migration on three branches.
TAO's core cut 56.15.0, whose only listed change adds a database index for ReadonlyLiteral properties. On the same day it shipped 56.14.11, 56.14.8.1 and 56.13.1.3, each deprecating a bad migration on its branch. Earlier October releases were single-fix 56.14 patches on Resource Manager and task logging.

Perusall
0.0EDTECH
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 opens the 56.15 line with a database index while patching a bad migration on three branches.
◆ Current state
TAO's core cut 56.15.0, whose only listed change adds a database index for ReadonlyLiteral properties. On the same day it shipped 56.14.11, 56.14.8.1 and 56.13.1.3, each deprecating a bad migration on its branch. Earlier October releases were single-fix 56.14 patches on Resource Manager and task logging.
◆ Where it's heading
The project is still in maintenance mode ahead of its 2026-11 LTS, and the migration fix backported to three branches shows it supports several release lines at once. Opening 56.15 with a performance index instead of features suggests the LTS may be cut from the new line.
◆ Prediction
Expect more single-fix patches across 56.13–56.15 and then the November LTS. The entries don't show which line the LTS will be based on.
