What is Blockly?

Post-v13 cleanup: three beta tags in one evening, two of them carrying nothing at all.

Blockly is servicing the v13 line it opened in June with keyboard navigation and screenreader support on by default. The 13.2.2 beta train tagged three times in under three hours, but only beta.0 carries changes — an undo-stack corruption fix, a nested-tree traversal speedup, and focus restoration on toast dismissal. beta.1 and beta.2 record an empty commit range.

What is Sakai?

Sakai keeps a slow annual cadence — Sakai 25 in mid-2025, 25.1 point release in late 2025, with most feed entries being archival docs.

Sakai's recent feed surfaces release-cycle documentation rather than feature-by-feature changelog content. Visible artifacts include the Sakai 25.1 Features-by-Tool index, a Sakai release-date list (with 25.0 in June 2025 and 25.1 in November 2025), and older 25/23/22 release-notes pages. Some entries are decade-old 2.x tool documentation that resurfaces because page metadata changed.

5.0

Post-v13 cleanup: three beta tags in one evening, two of them carrying nothing at all.

◆ Current state

Blockly is servicing the v13 line it opened in June with keyboard navigation and screenreader support on by default. The 13.2.2 beta train tagged three times in under three hours, but only beta.0 carries changes — an undo-stack corruption fix, a nested-tree traversal speedup, and focus restoration on toast dismissal. beta.1 and beta.2 record an empty commit range.

◆ Where it's heading

The work since v13.0.0 is consolidation around focus, rendering, and performance rather than new surface area — insertion markers rewritten for memory, connection-database updates sped up, field labels made translatable. Accessibility remains the organizing concern, now expressed as correctness fixes in the machinery that shipped rather than new capability. The rapid empty beta tags suggest release automation firing on non-code commits.

◆ Prediction

Expect a 13.2.2 final shortly, continuing the pattern of small fix batches on the v13 line. Nothing in these entries points to a v14 or a new feature theme.

Sakai keeps a slow annual cadence — Sakai 25 in mid-2025, 25.1 point release in late 2025, with most feed entries being archival docs.

◆ Current state

Sakai's recent feed surfaces release-cycle documentation rather than feature-by-feature changelog content. Visible artifacts include the Sakai 25.1 Features-by-Tool index, a Sakai release-date list (with 25.0 in June 2025 and 25.1 in November 2025), and older 25/23/22 release-notes pages. Some entries are decade-old 2.x tool documentation that resurfaces because page metadata changed.

◆ Where it's heading

Sakai continues its longstanding annual major-release rhythm with point releases on top, consistent with a mature open-source LMS used predominantly in higher education. There is no observable pivot toward AI features, agentic workflows, or new platform surfaces in this feed — the trajectory is steady stewardship.

◆ Prediction

Expect Sakai 26 along the established annual pattern, with continued point releases and Apereo-aligned community work. Any AI integration would be a notable departure from the current cadence and would be unusual to see appear without clear advance notice.
