Improvements - Automatically executes a garbage collection when low space is signaled
- VM Object allocation functions returns CObjectPointer instead of (STObject *)
- New VM alloc function for ExternalAddresses
- Process list generated in GC primitive
- Implemented low level debug mechanism to show message sends
- Move traitComposition instance variable from ClassDescription to Behavior
Bug Fixes - TranscriptStream cyclic buf in #pastEndPut:
- MaxObjects too big, optimized code failed to open AppLauncher
- #printOn:base: defined in SmallInteger causes FractionTest #testFractionPrinting to fail
- gmalloc overflows allocatedObjects[]
- newIntegerOrLong() must convert unsigned ints
- ExternalAddress fromInteger: does not handle negatives
- uncheckedAtPut din't check values between 0 and 255 for variableByteObjects
- garbage collector flush at cache while being used
