Feature description
On version 2.* you could set the customEndpointUrl to https://example.com, and the SDK would append /api/v2/logs/. This has changed in version 3.*, but there is no mention of it in the migration guide, and in the changelog of version 3.0.0 it is listed as an improvement, not a breaking change, so it is easily overlooked.
Proposed solution
Update the migration guide.
