2021/3/11 Workers Runtime Release Notes

New this week:

  • When the Workers Runtime itself reloads due to us deploying a new version or config change, we now preload high-traffic workers in the new instance of the runtime before traffic cuts over. This ensures that users do not observe cold starts for these workers due to the upgrade, and also fixes a low rate of spurious 503 errors that we had previously been seeing due to overload during such reloads.

(It looks like no release notes were posted the last few weeks, but there were no new user-visible changes to report.)
