 # Revision history for brittany
 
-## 0.14.0.0 -- November 2021
-
-* #357: Added support for GHC 9.0. Dropped support for all other versions of GHC.
-  * ab59e9acc3069551ac4132321b285d000f5f5691: Removed runtime dependency on `ghc-paths`.
-  * fa8365a7fa9372043d5a1018f2f7669ce3853edd: Started providing pre-built binaries for Linux, MacOS, and Windows.
-  * Many other changes to Brittany's internals and exposed Haskell interface, but (hopefully) no changes to its command-line interface.
-
-## 0.13.1.2 -- May 2021
-
-* #347: Allowed hspec 2.8. Thanks @felixonmars!
