Release candidate notes for v1.1.0

snarkVM Consensus Changes

The most consequential change in this release is that a consensus update is going to take place, introducing two features requested by many members of the Aleo community:

• Use timestamp-based block_reward and coinbase_reward algorithms (instead of height-based) for more accurate rewards emission. ARC42 - AleoNet/snarkVM#2569
• Reduced mapping base cost from 10,000 to 1,500 microcredits for GET operations based on benchmarked runtime performance, optimizing chain economics while maintaining safety margins. AleoNet/snarkVM#2564

The consensus changes will occur at the following blocks:

• Canary - Block 2,900,000
• Testnet - Block 2,950,000
• Mainnet - Block 2,800,000

ATTENTION: Validators that do not upgrade in time will be at risk of forking and require manual intervention. Clients that do not upgrade will be at risk of halting until an upgrade occurs.

Other important changes
