``libpq`` library the module was compiled/loaded with
(:tickets:`35, 323`).
- The attributes `~connection.notices` and `~connection.notifies` can be
customized replacing them with any object exposing an `!append()` method
(:ticket:`326`).

enabled, convert arrays of network types to lists by default. The old `!Inet`
adapter is deprecated (:tickets:`317, 343, 387`).

- Give precedence to `!__conform__()` over superclasses to choose an object
adapter (:ticket:`456`).
- Using Python C API decoding functions and codecs caching for faster
unicode encoding/decoding (:ticket:`473`).

``async`` will become a keyword (:ticket:`495`).

control the session characteristics as it may create problems with external
connection pools such as pgbouncer; use :sql:`BEGIN` options instead
(:ticket:`503`).

`~connection.autocommit`; added `~connection.readonly`,
`~connection.deferrable` writable attributes.

Bug fixes:

- Throw an exception trying to pass ``NULL`` chars as parameters
(:ticket:`420`).
- Fixed error caused by missing decoding `~psycopg2.extras.LoggingConnection`
(:ticket:`483`).

- Dropped support for client library older than PostgreSQL 9.1 (but older
server versions are still supported).
- `~connection.isolation_level` doesn't read from the database but will return
`~psycopg2.extensions.ISOLATION_LEVEL_DEFAULT` if no value was set on the
connection.
- Empty arrays no more converted into lists if they don't have a type attached
(:ticket:`506`)
