With the Commodore accelerators of the period (A2620, A2630) you needed a later version of the accelerator's ROM to use anything above Kickstart 1.3 otherwise you got a red screen.
No idea about GVP but it could be the same.
Some people are saying 4.15 is the latest but based on what I've seen, this version appears to be 4.5 and that also appears to be the version in the screenshot I provided. Can anyone explain this discrepancy? Is 4.5 perhaps a third-party ROM?
4.5 (i.e. 4.05) is an earlier version. 4.15 is the latest.
Note 1: Yes, 4.15 really is the latest one. Hint: Which section would you expect to come first in a book: 4.5 or 4.15? — Note 2: O well … seems like the previous one was too subtle for some of you, so let me try again: like section numbers in a book, version numbers are not decimal fractions; dots (yes, there may even be more than one, though not normally on Amiga libraries and devices because of the lib_Version and lib_Revision fields) within version numbers (and, in fact, section numbers) are merely separators between independent integers. Got it now? If not, have a look at page 110 in the User Interface Style Guide. There's also an article on version numbers by Carolyn Scheppner in the March/April 1991 issue of Amiga-Mail. Sheesh … — Note 3: C'mon folks, even if your EPROM burner doesn't handle Intel hex records, it can't be that difficult to convert them to binary, can it?
