Copilot knowledge bases in Visual Studio (preview)

GitHub Copilot Enterprise subscribers in Visual Studio can now use Copilot Chat to get answers enriched with context from Copilot knowledge bases. To try out this functionality, you’ll need to be running Visual Studio 17.11 Preview 3 or later.

You can access a knowledge base from any Copilot Chat conversation by typing @github, pressing the # key, selecting a knowledge base from the autocomplete, and then entering your question. Copilot will respond, using the Markdown documentation in your knowledge base as context for its answer.

For more details, check out the docs for Copilot Chat in Visual Studio.

Starting today, the npm registry will begin removing README content from package version metadata to reduce the size of package packuments, and improve the performance of the registry and package managers, including the npm cli.

A packument is the top-level package document that lists the set of manifests for available versions for a package. Users can observe the packuments using tools such as pacote.

The various improvements, features, and fixes shipped in June for iOS and Android.

In June, we released a number of improvements to the GitHub Mobile apps, mostly focusing on accessibility and enhancing existing features.


We now allow users to navigate to GitHub URLs by pasting them into the search bar on the Home tab. This makes it easier to quickly access repositories, issues, and pull requests from the app.


We’ve added the ability to hide disruptive comments within GitHub Discussions, and have added syntax highlighting for Haskell code snippets.

  • Addressed memory leaks when viewing changed pull request files and pinned repositories on user profiles.
  • Enabled opening draft releases without a tag directly within the app.
  • Displayed line counts next to long file names in pull request files changes navigation.
  • Aligned placeholders in comment views to the inputted text.
  • Improved keyboard navigation in the Explore feed to open selected repositories within the app instead of a web browser.
  • Aligned the account selection chevron next to the username in the Profile for accounts without a display name.

  • The name input dialog in the new file creation flow now alerts users when attempting to use unsupported recursive paths.
  • Resolved issue where in-app language preferences were not applied to all sections in the issue or pull request screens.
