Version 0.104.0 emitted an ImminentRemovalWarning when using the old interface. This warning is now printed to stderr by default. A user can still turn off these warnings via the warnings module.
The develop branch on github will be updated to completely remove the old interface. At this point the client interface will be the only interface available when using the develop branch on github.
A 1.0 alpha version will be released. By default, pip will not pick up any alpha/beta releases.
A 1.0 beta version will be released.
A GA (1.0) version of botocore will be released.
