It's fresh & clean IPFS nodes for browser/nodejs.
We've to experiment with IPNS TTL again to see how long we can keep IPNS records resolvable without republishing.
We could run non-custodial IPNS republishing service like w3name's OR use multiple services to do same..
& on other side of this equation we also have to check how fast/frequently can we propagate multiple IPNS records without breaking stuffs.

We've to keep track of records version to find latest published ipfs hash under ipns. if bad client publish v2 while old v99 is still out there it'll be rejected/accepted by different nodes as they're only aware of only v<2 Or v>2??

• we've to add & auto update text record IPNS_VERSION = <N++> to track current version.
