deal.II vs Sanity: at a glance
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 Sanity?
Sanity's MCP server hits v2.33 with safer publishing guards as Studio bug-fix cadence accelerates
Sanity is running two parallel tracks simultaneously: Studio (v6.14.x) is receiving rapid bug-fix releases targeting real-world pain — Portable Text data-loss risks, appearance theming inconsistencies, popover UX regressions. At the same time, the MCP server is iterating weekly from v2.31 to v2.33, adding revision guards for safer publishing, distributed-tracing auth fixes, and token-efficient query responses. The combined picture is a team hardening both the human-facing editor and the AI-tool-facing API interface.

◆ 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.
Sanity

Sanity's MCP server hits v2.33 with safer publishing guards as Studio bug-fix cadence accelerates
◆ Current state
Sanity is running two parallel tracks simultaneously: Studio (v6.14.x) is receiving rapid bug-fix releases targeting real-world pain — Portable Text data-loss risks, appearance theming inconsistencies, popover UX regressions. At the same time, the MCP server is iterating weekly from v2.31 to v2.33, adding revision guards for safer publishing, distributed-tracing auth fixes, and token-efficient query responses. The combined picture is a team hardening both the human-facing editor and the AI-tool-facing API interface.
◆ Where it's heading
Sanity is building the MCP server into a production-grade write interface for AI agents. The `ifRevisionId` guard in v2.33 — which causes publishing to fail if a draft changed since the caller read it — is the kind of concurrency safety needed before AI agents can reliably edit live content. Studio stability work is catching up after a period of fast feature shipping. Expect MCP tool coverage to broaden and the auth/schema layers to continue hardening for enterprise-scale deployments.
◆ Prediction
The next MCP server release will likely add more write-path safety features — document locking or conflict detection. Studio v6.15 will address remaining edge cases exposed by the MCP surface's broader read/write coverage.
