The Windows installer has been produced by hand: build the TSF DLLs and the Server locally, build the settings page, copy dictionaries out of a developer checkout, then run the msime-installer scripts against a self-signed certificate. This automates that end to end, keeping the same artifact name the releases have always carried, MetasequoiaIME_Setup_v<version>.exe.
The workflow follows the shape of MSIME-Apple's release.yml. release-please owns version.txt and opens a release PR; merging it creates a draft release, which the publish path then builds and fills in. A manual dispatch can rebuild an existing draft tag, and validates that the tag matches version.txt at an immutable commit SHA before anything is built.
Four jobs feed the packaging job: the TSF DLLs for x64 and Win32, the Server Release build, and the settings page. msime-installer needs no changes because the packaging job stages each checkout under the historical directory name its scripts already address, so Prepare-PackageFiles.ps1 and Compile-Installer.ps1 run unmodified. windows-2025 ships Inno Setup 6.7.1, above the 6.6 the scripts require.
Dictionaries are not rebuilt here. They are downloaded from a dict-* release of metasequoiaime/MSIME-Dict and checked against its SHA256SUMS.txt, with the Mozc IPAdic / ICOT / Okinawa notice placed where Prepare-PackageFiles.ps1 expects so it reaches the installed product.
Signing follows the pattern MSIME-Apple uses: sign when the certificate secrets are configured, otherwise publish with an -unsigned suffix and say in the release notes that uiAccess will not take effect. Sign-PackageBinaries-Local.ps1 mints a self-signed certificate for local testing and is never invoked here.
release-please cannot drive the VERSIONINFO block in the resource script, which spells the version both as a comma quad and as a dotted string, so scripts/apply_version.py stamps it from version.txt before the release build configures CMake. It also has a --check mode. The committed resource moves off the stale 1.0.0.1 placeholder to the current 0.0.9.
The manifest starts at 0.0.9 rather than the four-part 0.0.9.2 that semver cannot express, so the next release will be 0.0.10, which still sorts after every existing tag.
