08:02 PM Ruby Feature #22067: New RUBY_TYPED_THREAD_SAFE_FREE bit to declare thread safe dfree functions

Updated the description to make it clear that this is a purely stricter dfree contract. I also added that `RUBY_TYPED_THREAD_SAFE_FREE` implies `RUBY_TYPED_FREE_IMMEDIATELY`.
I renamed the proposed flag to `RUBY_TYPED_THREAD_SAFE_FREE`,... jhawthorn (John Hawthorn)

05:56 PM Ruby Revision dd9213c4 (git): Convert object_tracing to use weak references

Object tracing listens to the NEWOBJ hook to see all objects allocated
while it is active. Previously it also enabled a FREEOBJ tracepoint to
drop each object's record as the object was freed.
However the FREEOBJ tracepoint only fires w... jhawthorn (John Hawthorn)

12:14 AM Ruby Revision 4f6c8c69 (git): Use stack callinfo/calldata for super dispatch

Previously vm_search_super_method would allocate a new callinfo and
write it back into the iseq's call data. Because iseqs can be shared
between Ractors (e.g. via Ractor.shareable_proc + define_method), two

11:32 PM Ruby Bug #22084 (Closed): invokesuper from define_method in Ractor can call wrong super method or crash

`vm_search_super_method` has an odd behaviour where it allocates new callinfo (ci) and assigns it back to the iseq. All of our other method calls only reassign the callcache (cc). Because this CI is used from the iseq immediately after f... jhawthorn (John Hawthorn)
