ADO.NET provider for Firebird 184.108.40.206 is ready
There's a new version of FirebirdClient waiting for you. Numbered 220.127.116.11. You can get the bits from NuGet (EF6-ready version) or from FirebirdSQL.org site (or directly).
All changes can be found in tracker. Most notable. Now we have support for NBackup and "integrated security" works also on 64bit systems (fix contributed by Nathan Fox).
