Patch Changes

• #713 25473ac Thanks @github-actions! - Release automation: auto-merge the changelog PR. The post-release step that opens the chore/changelog-vX PR now also merges it (queued auto-merge, falling back to an immediate squash merge). Previously the PR was only created and left open until a maintainer merged it by hand, which caused several releases to sit with a stale/missing CHANGELOG on main.

• #714 7cad2f4 Thanks @sbroenne! - Faster commits for docs-only changes. The pre-commit hook now treats the gh-pages/ documentation website as docs and skips the Release build, smoke tests and all release-packaging gates when a commit touches only documentation (Markdown, docs/, gh-pages/, changesets). Code commits still run the full validation suite, so nothing that ships is left unchecked — documentation edits just no longer wait minutes for binary/packaging gates that cannot be affected by them.

• #722 8e6d9f1 Thanks @sbroenne! - More reliable Python in Excel results. pythoninexcel get-result now detects when the Microsoft-hosted Python backend has finished computing by reading Excel's calculation state and the cell's #BUSY! placeholder directly, instead of guessing based on whether the value looked "stable" across repeated reads. The old heuristic could lock onto a stale placeholder and return the wrong value, which is why it needed retry loops to be dependable. A single get-result call now converges deterministically, and the default wait was raised from 15s to 30s to comfortably cover cold-start round-trips.

• #725 2b2b5df Thanks @sbroenne! - Reduced MCP Server telemetry noise and cost. The MCP Server no longer reports the .NET runtime's built-in HTTP-client connection-pool metrics (http.client.open_connections, http.client.active_requests, http.client.connection.duration, http.client.request.time_in_queue, http.client.request.duration) to Application Insights. These were emitted automatically by the telemetry SDK regardless of actual traffic and accounted for the large majority of telemetry ingestion volume, without providing any useful signal for this tool.

ExcelMcp 1.9.4

ExcelMcp 1.9.4

What's New

Patch Changes

• #706 987b021 Thanks @sbroenne! - Add a short "Also building PowerPoint decks?" tip right after the README's hero section, linking to PowerPoint MCP Server, mirroring the same repositioning done on the docs homepage.

• #702 08d2ec6 Thanks @sbroenne! - Release automation hardening: The post-release step that opens a PR to commit the compiled CHANGELOG.md no longer silently swallows failures. During the first live run of the new changesets-based release pipeline, this step failed (the repo didn't allow Actions to create pull requests) but was marked as a passing step, which is exactly the kind of silent failure the new pipeline was built to eliminate. The repo setting has been fixed and the step now fails the release run loudly if it can't create the PR.

• #709 1d8b3cd Thanks @sbroenne! - Fix JSON Schema array items format for Gemini API compatibility (#672)

  Removes nullable: true from array nodes and adds explicit type: string fallback for C# object nodes. This prevents MCP clients from emitting missing types or union schemas that the strict Gemini API validator rejects.

• #705 bf54607 Thanks @sbroenne! - Move the "Also building PowerPoint decks?" sister-project tip on the docs homepage to appear directly under the hero section (success callout + intro video) instead of at the bottom of the page, and simplify its wording so it doesn't depend on the Key Features section that now follows it.

ExcelMcp 1.9.1

ExcelMcp 1.9.1

What's New

Patch Changes

• #699 0e1c4eb Thanks @sbroenne! - Changelog generation now uses changesets (#698): Each PR adds a small, human-written note describing what changed for users, and these notes are compiled automatically into CHANGELOG.md and the GitHub Release notes when a new version ships. This replaces the old manual process, which had let several releases' worth of changes sit mislabeled as "Unreleased" for months. The changelog itself has also been cleaned up — the mislabeled entries were consolidated and condensed into clearer, less technical summaries.
