There have been a number of updates to master since the initial announcement. Thank you for all the feedback.
Most of the issues have been about the ARM64 code-generator. Some could be fixed easily but one has required more work. The symptom was an InternalError exception that indicated that the code was too large for the offset in an instruction. This has now been fixed by using a pair of instructions in that case but it has required changes to the run-time system to handle the different relocations that are needed. That had to be done for each of the major operating systems since Linux/BSD, Windows and Mac OS each have their own object code format.
It's possible, though unlikely, that these changes have broken something on platforms other than ARM so I will hold off the final release for a week or in case there are any problems.
