Hello @wiz, Please review.

bsiegert commented 1 year ago

Are you the new upstream? Or is that Github repository a fork? Is the other Boehm GC upstream dead? Please give a bit more context.

ivmai commented 1 year ago

Upstream development and release preparation happens on Github since ~2012 (https://github.com/ivmai/bdwgc). http://www.hboehm.info/gc/gc_source/ is a mirror maintained by @hboehm

@bsiegert, BTW I could reference similar work (update to v8.2.4) on other platforms:
