2026-10-01  Amiga Release 20 (Frotz 2.55)

  * Fixed verification, restart, saving and restoring for games packaged in
    Blorb files (.zblorb and .zlb).
  * Restored sound effects loaded from separate Infocom sample files and
    fixed playback of supported sounds embedded in Blorb files.
  * Fixed default save, transcript, recording and auxiliary filenames in
    FrotzStdIO. Long game paths and filenames no longer cause crashes or
    overwrite memory.
  * Games can save and load auxiliary files without a filename prompt when
    they request it.
  * Fixed incorrect colours and picture rendering, including colour display
    on public screens.
  * Fixed crashes when resizing a window while editing a full input line.
  * Damaged resource, preferences and sound-name files no longer cause the
    identified crashes or hangs.
  * Fixed dialog return values so requester choices are handled correctly.
  * Removed the ineffective -R option and old-save Preferences checkbox.
    Saving and restoring use Quetzal format; pre-Quetzal saves remain
    unsupported.

Amiga Release 19 (Frotz 2.55)

  * Updated the interpreter to Frotz 2.55, bringing upstream game
    compatibility improvements and bug fixes.
  * Save and restore use Quetzal format. Legacy pre-Quetzal saves are no
    longer supported.
