Change Log

v0.4.0-rc.3 - 2019-06-29

Fixed

• Significantly improved the performance of query and copy_in.

Changed

• The items of the stream passed to copy_in must be 'static.

v0.4.0-rc.2 - 2019-03-05

Fixed

• Fixed Cargo features to actually enable the functionality they claim to.

v0.4.0-rc.1 - 2019-03-05

Changed

• The client API has been significantly overhauled. It now resembles hyper's, with separate Connection and Client objects. See the crate-level documentation for more details.
• The TLS connection mode (e.g. prefer) is now part of the connection configuration rather than being passed in separately.
• The Cargo features enabling ToSql and FromSql implementations for external crates are now versioned. For example, with-uuid is now with-uuid-0_7. This enables us to add support for new major versions of the crates in parallel without breaking backwards compatibility.
• Upgraded from tokio-core to tokio.

Added

• Connection string configuration now more fully mirrors libpq's syntax, and supports both URL-style and key-value style strings.
• FromSql implementations can now borrow from the data buffer. In particular, this means that you can deserialize values as &str. The FromSqlOwned trait can be used as a bound to restrict code to deserializing owned values.
• Added support for channel binding with SCRAM authentication.
• Added multi-host support in connection configuration.
• The client now supports query pipelining, which can be used as a latency hiding measure.
• While the crate uses tokio by default, the base API can be used with any asynchronous stream type on any reactor.
• Added support for simple query requests returning row data.

Removed

• The with-openssl feature has been removed. Use the tokio-postgres-openssl crate instead.
• The with-rustc_serialize and with-time features have been removed. Use serde and SystemTime or chrono instead.
