PostgresKit 2.11.0 heavily revamped PostgresKit to take full (or near to it) advantage of the modern PostgresNIO APIs. These changes do the same for FluentPostgresDriver, including adopting the revisions made to PostgresKit's API. This incidentally results in a significant improvement in the layering of the three packages, with FluentPostgresDriver now relying almost entirely on PostgresKit alone rather than needing to separately know details of PostgresNIO (with one or two exceptions). The end result is much cleaner code and moderate performance improvements.

Swift 5.7 or later is now required.

Users who previously specified custom PostgresDataEncoder and/or PostgresDataDecoder instances in their database configurations will begin receiving deprecation warnings; the replacements are PostgresNIO's PostgresEncodingContext and PostgresDecodingContext:

let postgresEncoder = PostgresDataEncoder(json: JSONEncoder()) // deprecated
let postgresEncodingContext = PostgresEncodingContext(jsonEncoder: JSONEncoder()) // new
let defaultPostgresEncoder = PostgresDataEncoder() // deprecated
let defaultPostgresEncodingContext = PostgresEncodingContext.default // new
let postgresDecoder = PostgresDataDecoder(json: JSONDecoder()) // deprecated
let postgresDecodingContext = PostgresDecodingContext(jsonDecoder: JSONDecoder()) // new
let defaultPostgresDecoder = PostgresDataDecoder() // deprecated
let defaultPostgresDecodingContext = PostgresDecodingContext.default // new
