Graphite has introduced several updates and improvements over the past two weeks, focusing on enhancing collaboration and workflow for users. Key enhancements include improved functionalities for the `gt get` and `gt sync` commands, a keyboard shortcut for marking files as viewed, and the ability for bots and non-Graphite users to utilize the Graphite merge queue, particularly useful for automating tasks like merging dependabot PRs. The platform is also hosting events such as a launch week with new feature announcements and a live webinar with CEO Merrill Lutsky, aimed at demonstrating how its tools can improve engineering practices and developer satisfaction. Additionally, there is a focus on tracking PR sizes over time to improve review processes and an emphasis on integrating feedback from the community to guide future updates. Users are encouraged to share their experiences with continuous integration to further enhance support for stacked PRs.
