+GC Plans
+---
+* Added a new plan PageProtect, a plan to help debugging. It allocates each object
+  to a separate page, and protects pages when the pages are released.
+
+API
+---
+* Major changes to the ObjectModel trait: now a binding must specify each per-object
+  metadata used by mmtk-core, whether the metadata resides in header bits provided
+  by the VM or side tables provided by mmtk-core. For in-header metadata, a binding
+  can further implement how it can be accessed, in case the bits are not always available
+  to mmtk-core.
+
+Misc
+---
+* Refactored metadata to provide unified access to per-object metadata (in-header or side).
+* Refactored work packet statistics to allow other types of stats other than execution times.
+* Added the feature 'perf_counter' and the option 'perf_events' to collect data from hardware performance counters for work packets.
+* 'extreme_assertions' now also checks if values stored in side metadata are correct.
+* Fixed a bug that GenCopy may report OOM without doing a full heap GC.
+* Fixed a bug that existing mmapping of side metadata memory may get overwritten.
+* Fixed a bug that FreeListPageResource may return an incorrect new_chunk flag for the first allocation.
