Compare Source

[!WARNING]
v5.x of this provider is a ground-up rewrite of the SDK, using code generation from our OpenAPI spec.

There are backwards incompatible changes which are documented and outlined in the migration guide
however, we offer codemods to assist as well as the manual steps if you prefer.

[!NOTE]
v4.x will no longer be in active development per our support policy and all feature
development and improvements will land in v5.x.
