Compatibility warning
The ODEON software is forward compatible. This means that you may load a room that has been created in ODEON 14 (or earlier versions down to ODEON 3.0) into ODEON 15 and that ODEON will convert file formats as needed. This means that older rooms will load seamlessly into ODEON 15. It also means, however, that older versions of ODEON may no longer be able to load the room, as they will not recognize any newer file formats.
First time ODEON 15 attempts to load an old room, the user will be warned that it will no longer be compatible with older versions of ODEON. This allows making a backup copy of the room either from the Windows Explorer or using an older version of ODEON (indicated in the warning message).
ODEON 15 will give similar warnings in the future if attempting to load a room which has been loaded into a newer version of ODEON (e.g. ODEON 16). In that case, loading the newer room into ODEON 15 may damage data. ODEON 15 cannot know if the newer version has compatible file formats – the room may load into ODEON 15 without problems – but it cannot be guaranteed. Always consider seriously making a backup copy.
