In theory, it should work for MacOS as well.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-130398\n* gh-130550\n* gh-130552\n* gh-130554\n* gh-130572\n* gh-130573\n* gh-130593\n* gh-130966\n* gh-131088\n* gh-135928\n* gh-136173\n* gh-141951\n* gh-142012\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/markshannon","@type":"Person","name":"markshannon"},"datePublished":"2025-02-21T10:15:09.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/130396/cpython/issues/130396"}| route-pattern | /_view_fragments/issues/show/:user_id/:repository/:id/issue_layout(.:format) |
