Frequently asked questions
Check whether a runtime version is past end of life?
check_runtime_eol says whether a runtime version is past end of life, the date it ended or will end, the latest patch and the next supported line.
Pass runtimes by name and version, or the pin files of a repository such as package.json, .nvmrc, go.mod or a Dockerfile. A range such as >=18 is checked at its oldest version. Dates come from endoflife.date, which volunteers maintain, so confirm with the vendor before a contract or compliance decision. Tool: check_runtime_eol on https://devfacts.openkrill.app/mcp.
Is the MIT license OSI approved?
check_license returns the SPDX id, the full name, whether the OSI approves it, whether the FSF lists it as free and whether the id is deprecated.
Pass an SPDX id or a license name; a name that matches several licenses returns candidates. It identifies a license only: it does not say what the license permits, and it is not legal advice. Tool: check_license on https://devfacts.openkrill.app/mcp.
Can I use CSS container queries in Safari?
check_browser_support gives the Baseline status of a web feature and the first version of Chrome, Edge, Firefox and Safari that supports it, on desktop and on Android and iOS.
A browser shown as null has not shipped the feature. An unclear name returns candidate features to pick from. Tool: check_browser_support on https://devfacts.openkrill.app/mcp.
Which RFC obsoletes RFC 2616?
lookup_rfc returns an RFC's title, status, date, authors and abstract, and the RFCs it obsoletes, is obsoleted by, updates and is updated by.
Pass a number for the details, or words from a title to get up to five matching RFCs. Tool: lookup_rfc on https://devfacts.openkrill.app/mcp.
Breaking changes between two package versions?
get_release_notes lists each release between the version you have and a newer one, newest first, with its date, a short excerpt of its notes and a breaking flag.
It reads GitHub releases for an npm package, a PyPI package or a GitHub repository, and the changelog file when the releases do not reach back far enough; complete is false when neither covers the whole range. It is not a vulnerability check. Tool: get_release_notes on https://devfacts.openkrill.app/mcp.
