Improved Delegation UI & Management: 

The delegation interface has been redesigned for clarity and fairness:

• Prompts users with unstaked MPC to delegate
• Delegation buttons across node profiles
• New node scoring based on uptime, staking goals, and community alignment
• Powerful filters (search, stake availability, personal delegations only)

Oracle Rotation Capabilities: 

• Users can rotate expired oracle associations independently, eliminating reliance on unresponsive operators. 
• This has also been implemented for price oracles.

ZK Registry Optimization: 

• Inactive nodes were removed from the ZK registry. 
• Only active block producers are now allocated to ZK contracts, improving reliability.

WASM Off-Chain Execution: 

• Rust-based smart contracts are now extensible with off-chain components. 
• A self-deployed engine runs this logic (non-ZK only). Initial examples and docs are underway.
