This is Npgsql 2.2.0 Final Release
This release contains 249 commits since the last stable release. Includes bug fixes, improvements and new features.
Update notice: If you have been using Npgsql 2.2.0-rc2, you
don't need to update to this version. They are the same except for the
Assembly version information.
Major highlights
Visual Studio DDEX support
Kenji Uno added support for DDEX. Now you can use Npgsql with Visual
Studio data designer. This is a missing feature a lot of our users
requested in the past. Kenji added a tutorial about how to use Npgsql
with DDEX. You can find it here:
https://github.com/npgsql/Npgsql/wiki/Visual-Studio-Design-Time-Support---DDEX-Provider#install-npgsqlddexprovidervsix
Entity Framework
David Karlaš added support for EFMigration and Database creation in EF6+.
Now it is possible to start Code First projects without needing to
create a database upfront. EntityFramework and Npgsql will take care of
it.
Emil Lenngren added support for a lot of missing features of EntityFramework.
A list containing fixes from David and Emil as well as others for EntityFramework can be seen here:

SSLStream support
In this release, SSLStream is on by default.
If you want to use Mono.Security, you will need to use the following line in your code:
NpgsqlConnection.UseSslStream = false;
Note that in future releases, this option may not be available
anymore as we are removing the dependency on Mono.Security assembly. Let
us know in the
forums
if you have any problem with ssl when using SSLStream. This will help
us check if we will be able to remove Mono.Security assembly.
Added support for JSON, JSONB and HSTORE datatypes
Shay added support for those datatypes.
Added GSSAPI support on Windows
Brian Crowell added support for GSSAPI on windows. Now it is easier to use Active Directory when authenticating users.
Removed support for protocol v2
Postgresql versions which use only protocol 2 are very old and don't
receive support from postgresql group anymore. By removing support for
protocol version 2, we removed a lot of code and can focus on
functionalities provided by protocol 3.
Removed support for Postgresql 8.4 and below
In
this thread,
we talked about making Npgsql support the officially supported
postgresql versions. we talked about making Npgsql support the
officially supported postgresql versions. Postgresql has
a table of officially supported versions and we decided to follow this table to guide us which postgresql version we will have support to.
This doesn't necessarily mean that Npgsql won't work on unsupported
versions. It may work if we don't add any SQL or unsupported feature.
For example, today Npgsql 2.2 works only on Postgresql 8.2 and above
because we added server side support for command timeout handling and
some other queries which aren't supported on earlier versions.
If you are using earlier postgresql versions, please, use an older
version of Npgsql. We are creating a compatibility table to show which
Postgresql version Npgsql works with.
