Changelog
Changelog for Node Dev
ℹ️ These changes are relevant to: Those who build around the client side code. Alternative client builders, SMOLDOT, those who consume RPCs. These are people who are oblivious to the runtime changes. They only care about the meta-protocol, not the protocol itself.
[#8669]: cumulus-aura: Improve equivocation checks
Instead of just checking for the slot, we also take the block number and the relay parent into account (as we actually allow to build multiple blocks per slot). Then this pr also ensures that we are still able to import blocks from availability recovery. This ensures that a network doesn't get stuck on a storm of equivocations. The next step after this pull request would be to implement on chain slashing for equivocations and probably disabling of the offending author.
Changelog for Runtime Dev
ℹ️ These changes are relevant to: All of those who rely on the runtime. A parachain team that is using a pallet. A DApp that is using a pallet. These are people who care about the protocol (WASM, not the meta-protocol (client).)
[#7785]: pallet scheduler: fix weight and add safety checks
Changes:
- Add runtime integrity test for scheduler pallet to ensure that lookups use sensible weights
- Check all passed storage names in the omni bencher to be known by FRAME metadata
- Trim storage names in omni bencher to fix V1 bench syntax bug
- Fix V1 bench syntax storage name sanitization for specific Rust versions
I re-ran the benchmarks with the omni-bencher modifications and it did not change the proof size. I reverted the commit afterwards to reduce the noise for reviewers.
Changelog for Runtime User
ℹ️ These changes are relevant to: Anyone using the runtime. This can be a token holder or a dev writing a front end for a chain.
[#8173]: Expose current advertised xcm version
