Salesforce Legacy API retiring?

Using Gravity Forms Salesforce Add-on plugin for years now, but I’ve received an alert from Salesforce that their legacy APIs are being retired. Will that impact this plugin? (As per Salesforce support, Gravity forms uses version 27.0?)

“Salesforce Platform API legacy versions 21.0 through 30.0 are going to be retired as part of Salesforce Summer Release (scheduled on 06/03/23 for JDRF Production instance) and no longer supported by Salesforce. When versions 21.0 through 30.0 are retired, applications consuming these versions of the API will experience disruption as calls will fail and result in an error indicating that the requested endpoint is not found and unable to be processed by the platform. If any of the applications you are responsible for, please check to see if the application uses any of the listed versions and needs an update. 

Here is the article with the details and also list of APIs that will be retired:?https://help.salesforce.com/s/articleView?id=000389618&type=1“
