I created an auto-update system based on IPNS with version checker. It supports win 7-win 11 and all linuxes. I use it for my bigger repo Tor Portable, and it works well here. It utilizes good basic IPNS features and concepts, it was called IPNS-RV in the first iteration, I renamed it because it may work not only with IPNS, but it was build for IPNS, so it works here natively.

There are mentions of IPNS in description, only IPNS links in the code, etc., so I hope it is clear enough that it is and always was IPNS based, I very much wait for ipns follow implementation, it will back up the system heavily.

Upd. I added the ipns republisher with portable dependencies.
