Patch PE80-0902091
------------------

Platforms: All

* This patch enables dbutil to change item order (#3689).

  item order.


Patch PE80-0901090
------------------

Platforms: All

* Fixed an internal race condition that could cause a database
  server abort in rare cases when concurrently disconnecting 
  multiple database sessions (#3696). A message like below is 
  output to the log file:

  Assertion failed: thread_rwlock_destroy failed
  server panic: Aborting on internal failure, file thread.c, line 1815

  The stack trace shows the following call stack:
  (1) thread_rwlock_destroy
  (2) Node_DeleteNodeMempageIfEmpty
  (3) Node_Delete
  (4) Tlog_Destroy
  (5) idb_exit_session

* The dbctl forwardlog status command no longer requires dba 
  privileges.


Patch PE80-0812180
------------------

Platforms: All

* During an automatic forward-log file switch it could happen in rare
  cases that transactions were not written to the forward-log (#3694).

  As a consequence, a recovery or replication from this forward-log
  would fail, for example with a message like below:

  recovery failed in action ... page ... not in expected state
  server panic: Fatal problem detected in btree_FWR__verify_page
  Assertion failed: h->lower == data->lower

* A DBGET mode 6 or 16 on an index item could improperly return an
  end-of-chain condition when the last key in the index was deleted
  (#3683).
