 This release deprecates support for running against an arbitrary Pants commit using
-`PANTS_SHA=abc123... pants ...`. Pants no longer
-publishes the artifacts required for this for new commits, and so this is becoming less and less

 - Use a released version of Pants.
 - Run pants from sources (for example: `PANTS_SOURCE=/path/to/pants-checkout pants ...`).
