Which version is about to be released? It should be 1.29 I believe, but the repo https://github.com/meraki/openapi is showing 1.30 as being the current release.
This repo is supposed to be the source of truth as per https://developer.cisco.com/meraki/api-v1/#!versioning
Normally future versions would be on side/beta branches and main would be the current released version.
According to the https://github.com/meraki/openapi/releases/tag/v1.29.0 tag, this was released on Jan 4th, but the changelog/release notes don't appear to be updated.
