Free release notes checker and template

Paste the notes for one release and get a list of the lines that read like commit messages, carry bare issue numbers or bare links, still contain a TODO, or use developer words where customers will read them. Or make a release-notes file with a section for each reader. It runs in your browser: nothing is uploaded.

The checks are the same word lists the kit uses (the node build.mjs check command). They are simple patterns, not understanding: they miss things and sometimes flag a sentence that is fine. The file format is the kit's: front matter, ## Users style sections, ### Added style groups. See what the kit builds from files like this.

What the checker looks for

• Lines that start like a commit message (fix:, feat:, chore(deps):).
• Bare issue or pull request numbers such as #412 with no link and no explanation.
• Web addresses pasted without link text, and links broken by a space between the brackets.
• TODO, WIP and FIXME left in the text.
• For customer-facing notes: words like refactor, dependency, endpoint, payload, pull request, migration and CI.
• Items shorter than 8 or longer than 400 characters.
