Pebble 2.0.0 release. This release enables all of the behaviour previously gated behind `-strict` as defaults. If you were not running Pebble 1.0.x with `-strict` already you may find this is a breaking release that requires client bugfixes. If you were previously running Pebble 1.0.x with `-strict` you should find 2.0.0 is a drop-in upgrade.
