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?
One feature, four branch tags — TAO's feed is backport plumbing, not release news.
Every entry in this feed is a backport. Three of the five tags carry the same change — the AUT-4590 dual preview feature and its flag — fanned across the v56.1, v56.3.1, and v56.3.5 construct lines, while the v55.0.1 line receives only dependency bumps. Release bodies are a PR reference and a version range; none describes what the change does for users.

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
2.5EDTECH
One feature, four branch tags — TAO's feed is backport plumbing, not release news.
◆ Current state
Every entry in this feed is a backport. Three of the five tags carry the same change — the AUT-4590 dual preview feature and its flag — fanned across the v56.1, v56.3.1, and v56.3.5 construct lines, while the v55.0.1 line receives only dependency bumps. Release bodies are a PR reference and a version range; none describes what the change does for users.
◆ Where it's heading
TAO is maintaining several customer-pinned construct lines simultaneously and moving work between them rather than shipping forward on a single trunk. The version numbers run non-monotonically as a result — v55.0.1.13 is newer than v56.3.5.2 by date — so tag order says nothing about what a given release contains. Nothing here indicates development on new capability.
◆ Prediction
Expect more per-branch backport tags with contentless notes as features already merged upstream are pulled into supported lines. Whether dual preview reaches the v55 line is not visible from these entries.
