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 Otus?

Otus drops AI into its gradebook and stacks bulk-action time-savers around it.

A coordinated April release pushed an embedded AI assistant into the Standards Gradebook alongside a wave of bulk-action quality improvements: bulk assessment comments, multi-class grade posting, multi-item plan status updates, and bulk plan PDF export. There's also a new question-level analysis view tied to standards. The shipping batch reads like a single coordinated quarterly release rather than scattered tweaks.

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.

1.3

Otus drops AI into its gradebook and stacks bulk-action time-savers around it.

◆ Current state

A coordinated April release pushed an embedded AI assistant into the Standards Gradebook alongside a wave of bulk-action quality improvements: bulk assessment comments, multi-class grade posting, multi-item plan status updates, and bulk plan PDF export. There's also a new question-level analysis view tied to standards. The shipping batch reads like a single coordinated quarterly release rather than scattered tweaks.

◆ Where it's heading

Otus is moving from being a passive data system to an active assistant for teachers — embedding AI into the workflow where teachers already spend the most time, and removing per-student clicking through bulk operations everywhere. The combination of AI Insights and pervasive bulk actions points squarely at one outcome: cutting the per-teacher time cost of standards-based grading.

◆ Prediction

Expect AI Insights to expand beyond the Standards Gradebook into Plans, Reports, and parent communication next. The bulk-action pattern will likely reach assessment authoring and rubric creation.
