Hi,
Thanks for reaching out to us here with your query. We usually release the new version of the InfiniteWP plugin in a wave(releasing to a few users). The client plugin update will be sent directly to your IWP admin panel from our server.
Once we ensure that our released version is bug-free, we will push the IWP client update to the plugin repository. So, you will only get the update notice on your InfiniteWP admin panel and see a different version on the WordPress plugin repository.
I hope this clarifies your query, and please don’t hesitate to contact us again for any questions or concerns
Cheers!
