1.6.16
• Fixed – Lower the number of requests, when trying to acquire a distributed lock.
• Fixed – Problems with continuations and batch continuations, when using existing `SqlConnection` instance.
• Fixed – Distributed locks were silently released, when passing explicit closed connection to a storage.
• Fixed – `KeyNotFoundException` errors on various dashboard pages don't appear anymore (by @benjymous).
• Fixed – "Cannot release the application lock because it is not currently held" exceptions, when connection was closed.

• Fixed – Counters query returned inconsistent results during CountersAggregator executions.
• Performance – Added missing NOLOCK hint for monitoring queries when using SqlServer-based queues.
• Performance – ExpirationManager is forced to use index seek operations for cascade deletions.
• Performance – CountersAggregator now uses clustered index scan to issue less logical reads.
• Performance – Paging queries in dashboard now use CTEs to utilize less logical reads.
   
1.6.4

1.6.3
• Fixed – Prevent `ExpirationManager`'s command from timing out, when there are a lot of records.
