caused the previous version to fail: excluded by constraint '>=0.12.5 &&

[__7] fail (backjumping, conflict set: diagrams-cairo, pango, text)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: lens, text, pango, diagrams-cairo,
LPFP, linear, template-haskell, linear:template-haskell
Try running with --minimize-conflict-set to improve the error message.
