I have Phabricator installation that use WikiMedia Sprint extension, but with the newer version of Phabricator it gives an error.
The error is on /project/sprint/ page, if you click on a sprint name you get:
>>> UNRECOVERABLE FATAL ERROR <<< Call to undefined method PhabricatorFeedQuery::setFilterPHIDs() /phabricator/libext/Sprint/src/controller/SprintProjectProfileController.php:79 ┻━┻ ︵ ¯\_(ツ)_/¯ ︵ ┻━┻
From what I read here and on MediaWiki project management wiki entries, I do not understand if this extension is still supported or I have to migrate to other tools: I think this should be stated clearly in the descriptions/download pages (e.g. initial README.md page) in case.
