New Sourcegraph changelog

We've built a new changelog to better highlight all the changes that will be coming in this new era of Sourcegraph. We are doubling down on the future of code understanding, and are ready to hit the ground running this year with exciting new improvements and features.

In the new Featured feed, you can find updates for our biggest changes in the form of standalone posts. In this feed, every Sourcegraph release - for example, Sourcegraph 6.12 - will get its own dedicated page that compiles all the changes from the release as well as all of its subsequent patches. Each release page will indicate the major updates included in the release, as well as a Details section with smaller improvements, fixes, and notes on deprecations.
