Release 1

   Initial release.

 Release 2

   Additional API_CLASS_ROOT action: API_ACTION_INTRODUCE
   Additional display refresh mode:  API_REFRESH_NOMARKER

 Release 3

   The API interface has partly been rewritten after introduction of undo/redo.
   Old style clients have to be recompiled.

   o The MASK/K option of GoldED's API command (used by all clients) has been
     renamed to WAIT/K in order to detect new-style clients. Same usage.

   o The static EditConfig->Current[] array has been replaced by a char pointer
     EditConfig->CurrentBuffer. Most API clients don't use this entry.

   o The static EditConfig->UndoBuf[] array has been replaced by a char pointer
     EditConfig->UndoBuffer. Most API clients don't use this entry.

   o The APIMessage structure has changed: API messages now give you access to
     global settings of the editor (e.g. the screen name): APIMessage->Global.
     APIMessage->api_User and APIMessage->api_Screen are obsolete and have been
     removed.

   o API clients are not allowed to change a text buffer directly and thus
     bypass the undo system; use APIMessage->Modify to pass modification
     requests to GoldED (example: api/spell/main.c) or use ARexx commands.

 Release 4

   o GoldED's internal text format has been changed slightly. Old style clients
     have to be recompiled. No source code changes required except usage of the
     API command: The WAIT/K option has been renamed to CLASS/K in order to
     detect new-style clients. Same usage.
