What's new

v3.0 [12 Jan 2016]
Npgsql 3.0.5 is out and available at nuget.org.
This release that could affect users setting MinPoolSize > 1. See issue #918.
Also, when closing a pooled connection that had an active transaction, that transaction would not be rolled back immediately. This could cause issues and has been fixed - transactions are rolled back immediately upon close. See issue #927.
Note that NpgsqlConnection’s DataSource property now returns a URL (e.g. tcp://localhost:5432). Code that relied on the contents of DataSource is probably now broken. See issue #903.
Npgsql 2.2 had a Windows installer that would set up Npgsql in the GAC and update your machine.config file - this installer has been revived and will now be released with 3.x version (check our releases tab on Github. Note that in most use cases, Npgsql should not be installed into the GAC - use Nuget instead.

v2.2 [4 Mar 2015]
2015-02-05 Npgsql 2.2.4.3
This is a bug fix release for 2.2.x series. Users should upgrade as soon as poosible due to a critical memory leak in 2.2.2.
