We have decided to add back Kulupu's roadmap page to clarify what's being developed and what's *not* being developed. https://wiki.kulupu.network/Roadmap
In particular, please read the "misinformation" section on this page. There was never a plan for Kulupu to become a "PoW hub".
The newest release of Kulupu is not vulnerable to the DoS vector mentioned in Polkadot v0.8.26-1 release note. You can continue to use Kulupu node version v2.3.0.
We always update all crate packages to its newest possible version every time when we update Substrate, so it just happens that we already bumped past the vulnerable package since last release in October. Watch Polkadot development channels if you want to learn more about this DoS vector.
Happy 3rd birthday to the Substrate codebase, upon which the #Kulupu blockchain is built! https://github.com/paritytech/substrate/commit/0d26ee79a820647ef6abcc999c9f65763e3d1ef7
