-    - Fix hangs with collective metadata reads during chunked dataset I/O

+      Improve porformance by skipping the search of the "tag_list"
+      if there are no "corked" objects when closing an object.
 
-      occurred with collective metadata reads enabled, hangs could be
-      observed due to certain MPI ranks not participating in the collective
-      metadata reads.

-      To fix the issue, collective metadata reads are now disabled during
-      chunked dataset raw data I/O.
+    - Fixed a potential invalid memory access and failure that could occur when
+      decoding an unknown object header message (from a future version of the
+      library).
