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.

[#5507]: Allow to enable full PoV size

A feature is introduced allowing a collator to enable full PoV size at compile time. WARNING: To use this feature, security considerations must be understood and the latest SDK version must be used.

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).)

[#5510]: Fix failing XCM from relay to Coretime Chain when revenue is zero

The coretime assigner now always includes UnpaidExecution when calling notify_revenue via a Transact, not just when revenue is nonzero. This fixes an issue where the XCM would fail to process on the receiving side.

[#5055]: Only log error in UnixTime::now call of the pallet-timestamp implementation if called at genesis

This minor patch re-introduces a check to ensure that the UnixTime::now implementation in the timestamp only logs an error if called at the genesis block.

Changelog for Node Operator

ℹ️ These changes are relevant to: Those who don't write any code and only run code.

[#5392]: Don't disconnect disabled nodes sending us dispute messages

No longer disconnect peers which we consider disabled when raising disputes as this will affect the approval process and thus finality.
