I just upgraded to ab4355cde0f8913b9e12be345f813f5ba7e0e468 (on stable) and ran into an issue.
Here's how I'm able to reproduce it:
- Create a new project
- Try to create a new "New Empty Board" for the project
Instead of a new board, I get this error:
>>> UNRECOVERABLE FATAL ERROR <<< Call to undefined method PhabricatorProjectWorkboardProfileMenuItem::validateTransactions() /usr/local/phabricator/phabricator/src/applications/search/storage/PhabricatorProfileMenuItemConfiguration.php:140
