+- Update alex to version 3.5.0.0.
+  ## Changes in 3.5.0.0
+
+   * Add option `--numeric-version`.
+   * Remove deprecated `-v` as alias for `--version`.
+   * Add `-v` as placeholder for a future `--verbose` option.
+   * Make `alex{G,S}etUserState` available with the `monadUserState-bytestring` wrapper
+     ([Issue #220](https://github.com/haskell/alex/issues/220)).
+   * Debugging lexer: print character in addition to its ASCII code
+     ([PR #252](https://github.com/haskell/alex/pull/252)).
+   * Tested with GHC 8.0 - 9.8.1.
