The integration between GitHub and Slack has been enhanced with new features designed to streamline productivity by turning conversations into actionable steps. Users can now execute common GitHub actions directly from Slack channels using slash commands like closing or reopening issues and pull requests, or opening new issues, although these commands require updated permissions from a GitHub organization owner or repository admin. Additionally, users can share and preview links from private GitHub repositories in Slack by inviting the GitHub integration to the channel. The app, built open source using publicly available APIs, encourages user contributions and offers a platform for developers to build their own integrations. These improvements aim to make collaboration between GitHub and Slack users more efficient and effective.
