ADO.NET provider for Firebird 18.104.22.168 is ready
There's a new version of FirebirdClient waiting for you. Numbered 22.214.171.124. 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).
