 [0.11.0.0] — September 2020
  * [Change internal representation of `ByteString`, removing offset](https://github.com/haskell/bytestring/pull/175)
-   * The old `PS` constructor has been turned into a pattern synonym that is available with GHC >= 8.0 for backwards compatibility.
+   * The old `PS` constructor has been turned into a pattern synonym that is available with GHC >= 8.0 for backwards compatibility. Consider adding `if !impl(ghc >=8.0) { build-depends: bytestring < 0.11 }` to packages, which use `PS` and still support GHC < 8.0.
  * [Fill `ForeignPtrContents` of `nullForeignPtr` with `FinalPtr` instead of a bottom](https://github.com/haskell/bytestring/pull/284)
-   * Note that `bytestring < 0.11` will be unbuildable with GHC >= 9.0.
+   * While `bytestring-0.11` is compatible with GHC >= 7.0, note that `bytestring < 0.11` will be unbuildable with GHC >= 9.0.
  * [Remove deprecated functions `findSubstring` and `findSubstrings`](https://github.com/haskell/bytestring/pull/181)
  * [Speed up sorting of short strings](https://github.com/haskell/bytestring/pull/267)
  * [Improve handling of literal strings in `Data.ByteString.Builder`](https://github.com/haskell/bytestring/pull/132)
