You are receiving this notice as you have used an API call taking the PlanID parameter in the last two months.
Previously, PlanID 1 has always corresponded with our current generation $20 plan. With the recent release of our $10 plan, this has changed. PlanID 1 now corresponds to our $10 plan, and all other PlanIDs have been incremented by 1. The following API calls are affected -
If you are using the PlanID numbers directly, you may want to look at avail.linodeplans() to ensure you are passing the correct PlanID for your particular use case. Note that certain wrappers e.g. the Linode CLI abstract this away and are not necessarily affected by this change.
This ticket will close in 48 hours. Feel free to update us if you have any questions or concerns.
