CRUSH v1.0 - released 18th June 1994
First version of CRUSH
CRUSH v1.1 - released 1st August 1994
Bug fix for -f "optimiser" which sometimes prevented the very best archive
being saved. Bug fix which cause CRUSH occasionally to overrun the required
number of trials. Also a minor optimisation added to -f that almost always
improves compression. v1.0 and v1.1 are completely cross-compatible and
neither of the v1.0 bugs would cause invalid archives to be created.
CRUSH v1.2 - released 22nd August 1994
Bug fix for -f when using CRUSH to create archives on a different drive
than the current one. CRUSH v1.1 would report a invalid error and give up.
Also when using CRUSH v1.1 to compress a group of zero-length files it
would report a spurious percentage improvement. CRUSH no longer allows
extension .CRU for external archive name (an invalid choice anyway).
Extra optimisation added to -f when used with larger values (e.g. -f40).
As before, all v1.0 and v1.1 archives are still valid and v1.2 compatible.
