This is yet another maintenance release that fixes a bunch of non-critical bugs in Hangfire.Core and Hangfire.SqlServer packages.

Hangfire.Core

• Fixed – Unexpected DateTime and DateTime? serialization issues in background job arguments (by @plaisted).
• Fixed – DistributedLockTimeoutException in some background processes now logged with “DEBUG” level instead of “ERROR”.
• Fixed – ElmahLogProvider to show errors when using SQL log (by @francnuec).
• Fixed – Last execution field isn’t shown on recurring jobs page, when background job has already expired.
• Fixed – Hangfire.SqlServer assembly doesn’t include version in the netstandard target.

Hangfire.SqlServer

• 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 – Allow to use zero timeout for SQL Server-based distributed locks.
