Hey all, We implemented this long-asked feature and I wanted to get feedback here. By default, these matcher annotations will be enabled, however, they of course can be disabled. Thoughts?

There is this top-left menu that is always available during a PR review so you can switch to other PR tabs (e.g. "Conversation") when you are deep down into "Files changed". I was always scrolling up and some PRs would take... a while... #GitHub

Coming soon, a GitHub Copilot App extension for JVM Pulse (using JFR and GC log data for AI-driven application run and analysis).

I got tired of optimizing Dockerfiles and containers. Been working on a new deployment model for workloads on Kubernetes, similar to WASI, similar to CloudFoundry/Tanzu. It is Kubernetes native. It is simple yet powerful. It gives more control to Ops teams. There are trade-offs.

We heard you. We agree. In light of recent developments in physical media, GitHub is proud to announce that you can now obtain your public repo on CD-ROM. Keep it. Lend it to friends. Pass it on to your children. Your code is physically yours, forever. Until you lose it, let's be real. gh.io/cd

Do it.
