It looks like you downgraded the agent version and the bitrise version from 1.45 to 1.43 within this update. Particularly for the default Xcode 11.7 stack and if you look into other stacks they have the same 1.43 version.
The downgrade results in slower behavior and every step on a workflow takes more time than before the upgrade.
Is it possible to set bitrise version in yml file or in settings somehow?
