Following today’s update, the v5 migration guide should mention all v5 endpoints in the table to explicitly state if each one has a migration path. The few endpoints that state they are “[n]o longer supported via the API” are not planned to be provided by the shutdown date in February 2022.
Now that the decommission details and timeline have been announced, we will soon be updating UserVoice suggestion statuses related to v5 and checking them with the teams that own each product before doing so.
