Merge branch 'stable-3.8' into stable-3.9

* stable-3.8:
  Clarify constraints of project deletions
  Introduce projectVersion cache
  Rename getPathFromDynamoDB to getItemFromDynamoDB
  Handle project deletion
  Verify formatting using GJF 1.7

Note that since 3.9 formatting version is done with GJF 1.24, so the
"Verify formatting using GJF 1.7" commit was dropped.
