ppad-base64-0.1.1: CHANGELOG

# Changelog

- 0.1.1 (2026-10-10)
  * The portable implementation now lives in an internal
    'Data.ByteString.Base64.Pure' module, and
    'Data.ByteString.Base64.Arm' is no longer exposed. Both are hidden
    internal modules; the public API is unchanged.
  * Expands the test suite to exercise both the NEON and portable
    implementations, including on invalid and non-canonical inputs.

- 0.1.0 (2026-05-16)
  * Initial release, supporting basic encoding/decoding.
