What is Opencast?

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.

What is Processing?

Processing is shipping again — and quietly moved its renderer onto wgpu.

Processing spent much of 2025 with a stalled release train; 4.5.4 in June explicitly marked the restart, and three releases have landed since. The work splits in two: build and release plumbing (the Ant-to-Gradle migration now sitting on Gradle 9.x, a release workflow that survives a failed macOS notarization) and an editor-shell refresh built on Jetpack Compose and Material 3. Contributor volume is the other signal — most release notes are lists of first-time PRs rather than maintainer work.

Opencast vs Processing: editorial side-by-side

2.5

Opencast maintains three release lines in parallel, and its feed shows only version numbers.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

P3.8

Processing is shipping again — and quietly moved its renderer onto wgpu.

◆ Current state

Processing spent much of 2025 with a stalled release train; 4.5.4 in June explicitly marked the restart, and three releases have landed since. The work splits in two: build and release plumbing (the Ant-to-Gradle migration now sitting on Gradle 9.x, a release workflow that survives a failed macOS notarization) and an editor-shell refresh built on Jetpack Compose and Material 3. Contributor volume is the other signal — most release notes are lists of first-time PRs rather than maintainer work.

◆ Where it's heading

The plumbing work is close to finished, which frees attention for the graphics stack. `the-wgpu-moment`, a branch open for nearly a year, is now merged into main, pointing Processing away from Java plus OpenGL through JOGL. Expect the next stretch to be about making that path usable and testable rather than about the editor UI.

◆ Prediction

The likely next move is exposing the wgpu renderer behind an opt-in flag with an open call for testers, while the 4.5.x line continues as the stable Gradle and Compose track.
