 ## Add support for cidr <-> IPNetwork mapping
 
-.NET 8 added a new type [IPNetwork](https://learn.microsoft.com/en-us/dotnet/api/system.net.ipnetwork?view=net-8.0) which represents an IP network with an [IPAddress](https://learn.microsoft.com/en-us/dotnet/api/system.net.ipaddress?view=net-8.0) containing the network prefix and an `int` defining the prefix length. This type seems to be a perfect fit for PostgreSQL's `cidr` type, which is why we added support to read and write it. The default when reading a `cidr` is still NpgsqlCidr in 9.0, though this will likely change in Npgsql 10.0. See [this](https://github.com/npgsql/npgsql/issues/5821) issue for more info.

 Npgsql 9.0 has a new callback `NpgsqlDataSourceBuilder.NegotiateOptionsCallback` which is called while performing GSSAPI authentication (such as Kerberos). This allows users to modify [NegotiateAuthenticationClientOptions](https://learn.microsoft.com/en-us/dotnet/api/system.net.security.negotiateauthenticationclientoptions?view=net-8.0), for example changing `Credential` property to implement password-based Kerberos authentication.

 ### The default value of ConnectionLifetime property in connection string is set to 1 hour
 
-Previously, the default value of this property was set to 0, which made connections last indefinitely. The old behavior was problematic because each physical connection on PostgreSQL's side has holds on certain caches, which can only grow over time.
