-
for..innow allows accessing collection items by pointer - Error handling:
-
error()is removed -
exit()now accepts an error code returned to the OS and an optional error message -
umkaRun()andumkaCall()now return an error code (0 on success) -
umkaAlive()is added to check if the interpreter can still executeumkaRun()orumkaCall() -
std.Err,std.error(),std.exitif()are added for graceful error handling
-
- Unicode support:
-
printf()on Windows fixed - Locale parameter in
umkaInit()is deprecated
