Opencast maintains three release lines in parallel, and its feed shows only version numbers.
Opencast, the university lecture-capture platform, ships regular point releases on three supported lines: 20.x (current), 19.x and 18.x. Every feed entry is a version tag that links to external release notes, so the specific changes are not visible here. The steady pattern of 20.x and 19.x releases landing within a day of each other points to coordinated backporting.
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.

The steady pattern of 20.x and 19.x releases landing within a day of each other points to coordinated backporting.
The cadence is roughly monthly per line, with 18.x releases getting rarer, which fits a project that supports older majors for a set window and then retires them. Because the feed has no changelog content, it doesn't show which features are moving.
Expect 20.5 and 19.10 around late October and 18.x to wind down; what they will contain can't be read from this feed.

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.
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.
