v9.1.0

Changes:

1. Serde-based JSON support via serde_integration feature (thanks to @TheServerAsterisk).
2. Connect timeout is implemented and available through tcp_connect_timeout option and tcp_connect_timeout_ms url parameter.

v9.0.0

Changes:

1. JSON support.
2. openssl updated to v0.9
3. tcp_keepalive_timeout_ms option added.

JSON Support

1. FromValue is implemented for rustc_serialize::json::Json and for Unserialized<T> where T: Decodable:

   #[derive(RustcDecodable)]
   struct DecodableStruct {
       // ...
   }
   // ...
   let (Unserialized(val),): (Unserialized<DecodableStruct>,)
       = from_row(row_with_single_json_column);

2. From<Json> and From<Serialized<T>> where T: Encodable is implemented for Value:

   #[derive(RustcEncodable)]
   struct EncodableStruct {
       // ...
   }
   // ...
   conn.prep_exec("INSERT INTO table (json_column) VALUES (?)",
                  (Serialized(encodable_struct_instance),));

v8.0.0

Changes:

1. Reexport chrono and time crates (@deniskolodin).
2. Conditional compilation and io module refactoring (@deniskolodin).
3. socket, pipe and uuid features removed.
4. Native ssl support on OS X (via security framework).
5. Fix unicode handling in parse_named_params.
6. ssl feature is now opt-in.
7. GenericConnection trait introduced (@alex-gulyas).
8. Traits reexports moved to mysql::prelude module.

v7.1.2

#64 fixed.

v7.1.1

⚠️ Note that version bumped incorrectly so there is no v7.1.0

Changes (thanks goes to @Diggsey 👍):

1. utf8mb4 encoding used by default for mysql>=5.5.3.
2. Support for custom local infile handlers added.

v7.0.1

Numbers now allowed in named parameters names, but name can't start with a number.
:param1 now is a valid named parameter, but :1param still isn't.

v7.0.0

uuid version bumped.

v6.0.0

This release fixes typo in PooledConn::drop() which leads to huge performance regressions for cases where number of acquired PooledConns is greater than pool.min. It also fixes Pool::first_exec signature (mut removed) and adds implementation of From<[u8; 0..32]> for Value.

Also this release adds a bunch of performance improvements as a result of solving #53:

• Column was rewritten to speedup Column::from_payload and Column::clone(). It affects performance of prepare and prep_exec in all cases.
• Connectivity check was improved. It affects performance of Pool::prepare and Pool::get_conn.
• TLS slot for pool connection was added. It removes pool overhead in many cases.
• A way to turn off connectivity checks, pool-level stmt cache and TLS slot was added. Turning off connectivity checks may speedup batch jobs in cases when Pool::get_conn and Pool::prepare is frequently used.
• XXHash now used for stmt cache.
• InnerPool now using VecDeque to store connections.

v5.2.2

• params! macro was improved so this:

  // ...
  params! {
      foo => my::Value::from("foo"),
      bar => my::Value::from(42),
  }
  // ...

  now could be written like this:

  // ...
  params! {
      foo => "foo",
      bar => 42,
  }
  // ...

v5.2.1

• The lifetime of a pool is now untied from a Transaction in Pool::start_transaction
