  • Fixed a severe issue with file permissions and references, see above.

"Duration" is the duration for this install, and may not be representative.


  • bin/drydock lease now supports --count N, to acquire multiple identical leases.
  • bin/drydock release-lease and bin/drydock release-resource now accept --all. (This is for resetting things in development, and could make a huge mess in a production environment!)
  • Drydock now properly makes resources that were created or leased in the last 3 minutes exempt from reclamation.
  • Drydock no longer throttles pool growth rates to 25% of active resources, and now tracks leases and pending resources more competently. In general, bursty requests for resources should be satisfied far more effectively now.

Upgrading / Compatibility

  • Continued to improve PHP 8.1 compatibility.
  • Continued to improve support for whitelabeling (i.e., changing the software product names from "Phabricator" to something else) to support forks.
  • The Releeph application has been removed. This application was a minimally functional prototype with no known users in the wild.
  • The Phragment application has been removed. This application was a minimally functional prototype with no known users in the wild.
  • Fixed an issue with viewing revisions with no changesets (usually arising from automatic updates triggered by empty commits).
  • Fixed an issue where Herald could fail to properly extract the (empty) content from an empty commit.
  • Fixed an issue where certain object references could form a cycle and break object pages. This was reported via HackerOne in
