+0.8.0 (2021-11-01)
+===
+
+* Introduces A VM companion thread to trigger safe point synchronisation. This fixed a bug that
+  MMTk's call to `SafePointerSynchronize::begin()` may race with the OpenJDK's VM thread.
+* Changes `COORDINATOR_ONLY_STW` to `false`. Stopping and resuming mutators are done by the companion thread,
+  amd it is no longer a requirement for them to be done by the same GC thread.
+* Fixes a bug that for some allocations, both fastpath and slowpath were invoked.
+* Fixes a bug in generating code to set the alloc bit in C1 compiler.
+* Fixes a bug that some derived pointers were missing as roots.
+* Updates to mmtk-core 0.8.0.
