GitHub Actions: macOS virtual environment is updating to Catalina and dropping Mojave support

On November 4th, the macOS virtual environment for GitHub Actions will update to Catalina (v10.15), the latest version of macOS X. After the update, jobs using the macos-10.14 virtual environment will not run. Any jobs in your workflows that run on the macos-10.14 virtual environment must migrate to macos-latest.

We’re also making a few changes to the minimum supported versions of Xamarin and Xcode. Changes include:

  • Removed Xamarin.iOS SDK 12.*
  • Removed Xamarin.iOS SDK 11.*
  • Removed Xamarin.iOS SDK 10.*
  • Removed Xamarin.Android SDK 9.*

  • Removed Xamarin.Mac SDK – 5.*
  • Removed Xamarin.Mac SDK – 4.*
  • Removed Xamarin.Mac SDK – 3.*
  • Removed Xcode 10.*
  • Removed Xcode 9.*

Internal repository visibility is now generally available

The internal repository visibility is now generally available. In addition to recent updates, we’ve added the following capabilities:

  • Search now allows you to filter results for internal repositories using is:internal
  • Enterprise forking policy for private repositories now also applies to internal repositories
  • New internal API parameters for this feature are available for organization and repository endpoints.
  • Additional search indexes are being rebuilt over the next several days to return internal repository pull requests, issues, code, and other searchable objects

The internal repository visibility option makes it easier to innersource code and projects to fellow enterprise members while restricting access to outside collaborators. It is generally available to customers with an Enterprise account.

At this time we are planning to release this functionality to GitHub Enterprise Server version 2.20.
