-Fix race condition in change merge queue.
+Fix race condition in change merge queue when using Cherry-Pick submit
 There was a race in the merge queue between changes submitted via
 the UI, and merges scheduled by the background merge queue reload.
 This resulted in multiple submit actions being scheduled, leading
 to corrupt changes.
+Execute cherry-pick submit DML operations in a database transaction
+boundaries. In combination with implemented transaction management
+for Jdbc dialects it solves the problem recovering from collisions
+between interactive actions and background jobs.
+* In gwtorm the LIMIT clause was only honored when followed by a
+constant integer.
+When followed by a placeholder "?" it wasn't included in the generated database
+query. This caused poor performance when moving to the next change page for very
+big projects.
+* Fix sporadic SSHD handshake failures
+* gwtorm is updated to 1.7.1
+* sshd is updated to 0.11.1-atlassian-1
