## Changes in 3.5.2.0 * Use `byteSwap16#` and `byteSwap32#` on big-endian architectures instead of handrolling the implementation ([PR #260](haskell/alex#260)). * More descriptive error in `alexScan`; inline `alexScanUser` ([PR #262](haskell/alex#262)). * Tested with GHC 8.0 - 9.12.1.

This INLINE pragma for alexScanUser was added in 9.12, but then I ported the change to alex in 3.5.2.0 (haskell/alex#262). I didn't realize that GHC errors on duplicate INLINE pragmas, so this ended up being a breaking change. This change should be backported into 9.12
