What is deal.II?

deal.II ships one big finite-element release a year, then patches it twice

deal.II is on a steady annual major-release rhythm — 9.6 in late 2024, 9.7 in July 2025, 9.8 in August 2026 — with one or two bug-fix point releases filling each gap. Its GitHub release notes are deliberately thin: each one links out to a generated changes-between-versions page and spends its body on contributor credits. What the feed does show directly is the shape of the project, including a release-candidate train that runs about two weeks before each major.

What is Appsmith?

Appsmith 2.7 makes its MCP agent ask before deleting widgets and blocks stale edits.

Appsmith v2.7.0, released November 12, mostly extends the embedded MCP server: removing widgets now needs the user's approval, layout updates are refused if the page changed since the agent read it, and agents can build conditional forms, read editor-written JS objects and hide pages. It also adds Table auto height, tightens permissions for custom JS libraries and forking, and applies the restricted-host policy to S3 and DynamoDB datasources. Helm probe defaults and navigateTo behaviour change on upgrade.

deal.II ships one big finite-element release a year, then patches it twice

◆ Current state

deal.II is on a steady annual major-release rhythm — 9.6 in late 2024, 9.7 in July 2025, 9.8 in August 2026 — with one or two bug-fix point releases filling each gap. Its GitHub release notes are deliberately thin: each one links out to a generated changes-between-versions page and spends its body on contributor credits. What the feed does show directly is the shape of the project, including a release-candidate train that runs about two weeks before each major.

◆ Where it's heading

The contributor roster is the signal these notes carry best, and it is growing: 9.8.0 alone credits roughly two dozen first-time contributors against a recurring core of about sixty. Point releases stay narrow and mechanical — MSVC and C++20 compatibility, MatrixFree face handling, Trilinos/Tpetra fixes — which suggests release engineering is stable enough that regressions surface in a predictable band. Nothing in the feed indicates a change of direction; this is a mature library compounding.

◆ Prediction

Based on the 9.6 and 9.7 patterns, expect a 9.8.1 within roughly two months carrying compiler-compatibility and MatrixFree fixes, and the next major in mid-2027 preceded by a short rc1-through-rc4 train. The release notes themselves are unlikely to get more detailed given how consistently they defer to the external changelog.

5.0

Appsmith 2.7 makes its MCP agent ask before deleting widgets and blocks stale edits.

◆ Current state

Appsmith v2.7.0, released November 12, mostly extends the embedded MCP server: removing widgets now needs the user's approval, layout updates are refused if the page changed since the agent read it, and agents can build conditional forms, read editor-written JS objects and hide pages. It also adds Table auto height, tightens permissions for custom JS libraries and forking, and applies the restricted-host policy to S3 and DynamoDB datasources. Helm probe defaults and navigateTo behaviour change on upgrade.

◆ Where it's heading

Since Appsmith AI shut down in September, the MCP server has become the product's AI strategy: each release widens what outside agents can build and adds guardrails on what they can break. Security hardening of permissions and datasources runs alongside in every release.

◆ Prediction

Expect more MCP tools behind user approval and further 2.7.x patches for the Helm probe and navigateTo changes, as followed earlier minor releases.
