Collator v5.3.0 for Polkadot v0.9.18

on GitHub

This release contains the changes from polkadot-v0.9.17 to polkadot-v0.9.18.

Priority

‼️ High: If you are still running a collator older than polkadot-collator v5.2.0-76479e7f-x86_64-linux-gnu, you must upgrade your collator to this version before the runtime V800 is activated on chain as it introduces a new host function via #10741.

If you currently run the polkadot-collator v5.2.0-76479e7f-x86_64-linux-gnu, you may update at your convenience.
