Migration notice

There are no migration changes between 1.0.0-rc.1, and 1.0.0. However, if you are updating a project from a previous version please checkout the tag of your version, and work your way through the migration guides between versions.

Note that unstable drivers see can see a lot of churn between versions, it may be better to just try and adapt your code from the current documentation for those drivers.
