Released: Couchbase .NET SDK 2.2.2

Today we are releasing Couchbase .NET SDK version 2.2.2, a bug fix and follow up release to v2.2.1. Most of the improvements in this release are for a future improvement to the IO engine for Memcached K/V operations. Another important improvement in this release is a hook for allowing per request deserialization options via ITypeSerializer. This was added for the Linq2JSON project so that we could do cool things like inject proxies for change tracking. More about that in a later post!
