Statemine v500 RC2 (Polkadot v0.9.11)

on GitHub

Upgrade Priority: ❗️HIGH❗️
Due to the new runtime version only being compatible with the current binary release.

⚠️ This is a pre-release.

❗️Important Changes

• New digest item RuntimeEnvironmentUpdated: https://github.com/paritytech/substrate/pull/9580
  
  • THIS REQUIRES THAT ALL NODES ARE UPDATED BEFORE A RUNTIME UPGRADE IS APPLIED THAT INCLUDED THIS CHANGE
    
• Support for Asset Transaction Payment (#488)
  
  • This changes the transaction format by swapping out a SignedExtension which leads to a transaction_version bump to 3.
    

Notable Changes

• Metadata v14: https://github.com/paritytech/substrate/pull/8615
  
• Make Parachain sync protocol future proof: https://github.com/paritytech/cumulus/pull/640
  
• Fix state_subscribeRuntimeVersion for Parachains: https://github.com/paritytech/substrate/pull/9617
  
• Improve performance for Parachains when building blocks: https://github.com/paritytech/substrate/pull/9611
  
• * Transaction priority calculation was changed to be based on the tip to weight/length ratio (#645)
  
  • see https://github.com/paritytech/substrate/pull/9834 for details
    
• Add Transaction Fee RPC to Statemint/Statemine (#559)
  
  • Note that this does not support asset transaction fees, yet.
    
• Support for Reserve Asset Transfers via XCM (#552)
  
• Support for XCM v2 (#571) (see https://github.com/paritytech/polkadot/pull/3629 for details)
  

Other Notes

• The spec_version convention was changed from single digits to hundreds (so v5 is spec_version 500 now)
  
• The spec_version 5 runtime live at time of release is the hotpatch to runtime version 4 (you could think of it as 401 in the new format).
