 # 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!
-
-## 0.13.1.1 -- February 2021
-
-* #333: Allowed random 1.2. Thanks @felixonmars!
-* #334: Updated Arch install instructions. Thanks @ahstro!
-* #343: Allowed ghc-exactprint 0.6.4. Thanks @maralorn!
-
-## 0.13.1.0 -- December 2020
-
-* #330: Started sorting imports. Thanks @expipiplus1!
-
-## 0.13.0.0 -- December 2020
-
-* #324: Added support for GHC 8.10.
-  * Dropped support for GHC 8.4, 8.2, and 8.0.
-  * Thanks @jneira, @bubba, @infinity0, and @expipiplus1!
-
-## 0.12.2.0 -- November 2020
-
-* #207: Fix newtype indent in associated type family.
-* #231: Improve comments-affecting-layout behaviour for tuples.
-* #259: Data declaration for newtype and records. Thanks @eborden!
-* #263: Fix non-idempotent newlines with comment + where.
-* #273: Error handling.
-* #281: Fix moving comment in export list (haddock header).
-* #286: Fix comments in instance/type instances.
-* #287: Add support for pattern synonyms. Thanks @RaoulHC!
-* #293: Expose main function as a module. Thanks @soareschen!
-* #303: Readme: Supports 8.8. Thanks @andys8!
-* #311: Allows aeson-1.5.*. Thanks @jkachmar!
-* #313: Nondecreasing export list formatting. Thanks @expipiplus1!
-
-## 0.12.1.1 -- December 2019
-
-* Bugfixes:
-    - Fix layouting regression of record update for many/large fields
-    - Fix whitespace regression on ExplicitForall notation
-      (`foo :: forall  a . Show a => a -> a`, note the double space)
-      introduced in 0.12. (#264)
-    - Fix roundtripping of type equality constraint
-      `f :: ((~) a b) => a -> b` (#267)
-* One experimental feature addition: Turning brace notation semicolons into
-  newlines when formatting (see #270)
-
-## 0.12.1.0 -- September 2019
-
-* Support ghc-8.8
-* Support for OverloadedLabels extension
-  (thanks to Evan Rutledge Borden @eborden)
-* Support for Implicit Params extension (thanks to pepe iborra @pepeiborra)
-* Add flag `--no-user-config` to enable only using manually passed config
-* Disable the performance test suite by default to prevent spurious failures
-  on certain CI setups. The github/travis brittany CI still has all tests
-  enabled. See the `brittany-test-perf` flag in the cabal file.
-* Bugfixes:
-    - Fix one wandering-comment bug for let-in expressions
-    - Fix invalid result for prefix operator pattern matches
-    - Fix lambda expression with laziness/strictness annotation
-    - Fix parenthesis handling for infix pattern matches with 3+ arguments
-* Changes to layouting behaviour:
-    - For pattern matching and data/instance definitions, the usage of
-      parenthesis is now "normalized", i.e. superfluous parens are removed by
-      brittany.
-
-## 0.12.0.0 -- June 2019
-
-* Support for ghc-8.6 (basic support, not necessarily all new syntactic
-  extensions)
-* Support -XExplicitNamespaces and -XPatternSynonyms
-* Allow a --dry-run sort of operation via flag "-c/--check-mode"
-  (thanks to Doug Beardsley @mightybyte)
-* Include file name in errors about unsupported syntax nodes (thanks to @5outh)
-* Partially implement layouting class instances: Layouts children, but
-  falls back on ghc-exactprint for the instance head
-  (thanks to Rupert Horlick @ruhatch)
-* Implement layouting for type synonyms (thanks to Rupert Horlick @ruhatch)
-* Support -XMagicHash, -XUnboxedTuples (thanks to Sergey Vinokurov @sergv)
-* Support -XQuasiQuotes (no formatting applied to the splices; they are simply
-  retained without causing the dreaded "Unknown construct: HsSpliceE{}")
-    - `lconfig_allowHangingQuasiQuotes` controls whether multi-line
-      QuasiQuotes are allowed to start at the end of the current line, or
-      whether they are always placed in new lines.
-* Bugfixes:
-    - Fix rare-case alignment bug with IndentPolicyMultiple (#144)
-    - Make inline layout config apply to module header (#151)
-    - Fix unaligned import-hiding layout (#150)
-    - Fix idempotence violation for comments around if-then-else (#167)
-    - Fix comments having an effect on far-away parent node's layout (#159)
-    - Fix imports of type operators ("symbolic data types")
-      (thanks to Phil Hazelden @ChickenProp)
-    - Work around GHC and cabal-install misfeature ".ghc.environment files"
-      that could break brittany in unexpected and hard-to-understand ways
-    - Stop removing empty lines before `where` keyword in a couple of cases
-    - Fix functions with mixing prefix/infix style causing error (#234)
-* Changes to layout:
-    - Align usage of spaces for record update vs record construction (#126)
-    - More indentation to import-hiding-paragraph (follow-up to #150 fix)
-    - Record construction and update now are layouted in the same way
-      (thanks to Evan Rutledge Borden @eborden)
-    - Stop allowing single-line layout when there are comments between
-      arguments (#214) (thanks to @matt-noonan)
-* Various build-instructions and editor integrations

 - Default mode of operation: Transform a single module, from `stdin` to `stdout`.
