UPDATE (2014-09-06): Kenji Uno made an installer available which helps users to setup Npgsql to work with VS.Net Database Designer as well as EntityFramework. You can find more information about this installer here. You can find the installer in the downloads section.
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: https://github.com/npgsql/Npgsql/issues?direction=desc&labels=entity+framework&milestone=2&page=1&sort=created&state=closed
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.
Fixed bugs:
[#91] Support for EFMigration and Database creation
[#152] NpgsqlInterval different constructors different ToString
[#158] NpgsqlCommand.Dispose() should execute "DEALLOCATE " for a prepared command
[#177] XML data type doesn't seem to be quoting parameters properly on insert
[#179] NpgsqlCommandBuilder automatic sql commands configuration
[#188] Buffer too small problem in NpgsqlCopySerializer
[#201] Dynamic type parameters: Cannot cast System.Int32 into any valid DbType after upgrading from 2.0.14.3 to 2.1.2.0
[#208] ObjectDisposeException
[#217] Impossible to insert a Double.NaN value
[#219] [#1011005] using 2 NpgsqlCopyIn at the same time
[#223] HasRows property's bug
[#231] NpgsqlParameterCollection.Clear() doesn't reset NpgsqlParameter.Collection
[#225] Handle IEnumerable parameter
[#233] Cannot insert to tables which have only one column
[#246] Take followed by Skip is generated incorrectly in Entity Framework
[#262] FirstOrDefault() on navigation property subquery throws “Not Implemented” Exception
[#264] Mono.Security is outdated
[#269] Fix 's' value mapped to the 'a' byte
[#280] Bad SQL produced when selecting a field that was also used in the orderBy of a let subquery
[#287] Fix operator handling and date functions for EF
[#296] parameter parsing fails (regression) and duplicate [#240] NpgSqlCommand does not substitute parameters when there is a string with escaped apostrophe
[#315] Fix query parameter processing to more correctly match PostgreSQL's lexer

Npgsql 2.1.3
This version restores support for @@ operator (#135) which was removed in the previous version.
Npgsql 2.1.2
This version contains fixes for #165 (KeyNotFoundException when setting ApplicationName on NpgsqlConnectionStringBuilder) and a regression when using NHibernate with queries containing '<' operator. #193 (Less Than' prepare failing).
Note that version breaks support to @@ operator added by #135 . Glen Parker is working in a full solution which adds #135 support back. If you need #135 support, please, use the 2.1.1 version. Sorry for this problem.
