+
+## 8.10.0.5 released 2020-05-02
+- New modules
+  - `Language.Haskell.GhclibParserEx.GHC.Parser`, `Language.Haskell.GhcLibParserEx.GHC.Utils.Outputable` to replace `Language.Haskell.GhclibParserEx.Parse` and `Language.Haskell.GhclibParserEx.Outputable` (which remain for now but deprecated and will be removed in a future release)

+## 0.20200401 released 2020-04-01
+
+## 8.10.0.2 released 2020-03-30
+- Rework cabal flags; allow full configurability with a good default:
+  - Have two flags `auto` and `no-ghc-lib`. Default behavior exactly as `hlint` linking `ghc-lib-parser-8.10.*` if not on `ghc-8.10.*` and `ghc-8.10.*` otherwise.
+
+## 8.10.0.1 released 2020-03-28
+- Unless the Cabal flag `ghc-lib` is `true` link native ghc-libs (without regard for the compiler version)
+- Change the signature of `hasPFieldsDotDot`
+  - This has no impact on 8.8 parse trees but matters when it comes to >= 8.10
+- Change the signature of `isPFieldWildcard`
+  - This has no impact on 8.8 parse trees but matters when it comes to >= 8.10
+
+## 8.10.0.0 released 2020-03-24
+- First release of the ghc-8.10 series
+
 ## 8.8.6.0 released 2020-03-22
 - `Language.Haskell.GhclibParserEx.DynFlags` is now `Language.Haskell.GhclibParserEx.GHC.Driver.Session`

+Package `ghc-lib-parser-ex` does **not** conform to the [Haskell Package Versioning Policy](https://pvp.haskell.org/). Version numbers are of the form α.β.γ.δ where α.β corresponds to a GHC series and γ.δ are the major and minor parts of the `ghc-lib-ex-parser` package release. Examples:
 * Version 8.10.1.3 is compatible with any `ghc-lib-parser-8.10.*` (or `ghc-8.10.*`) package;
 * Version 0.20190204.2.0 is compatible with [`ghc-lib-parser-0.20190204`](http://hackage.haskell.org/package/ghc-lib-0.20190204).
