Next week's release will include the results of this work after these changes have time to stabilize on our internal Preview build, and Zed should feel more polished. We also discovered that pushing large numbers of excerpts onto multibuffers would block the main thread, so we now construct excerpts in a background thread and stream them into the multibuffer asynchronously. We want to know how Zed is performing so we can fix any issues and maintain our high performance standards as we add features.
