Weekly channel will serve 3.51
Quarterly channel will serve 3.50
Exact version numbers can be specified as v=3.51, v=3.50, v=3.49, or v=3.48.
Version 3.47 will be decommissioned. This was the last version supporting Internet Explorer 11.
If you don't specify a version (or request a retired version), you will be served a default version, which depending on your key configuration will be either 3.50 or 3.51. But a developer specified version will always be honored and served when requested when it's an existing version.
You do not need to change your code, but you should be aware of possible changes in your usage and billing in the first and second quarter of 2023. Please see http://issuetracker.google.com/issues/251853069
