Highlights

This release features the 1.0 version of AVM, extending Algorand's smart contract capabilities for even greater composability. Highlights in this release include:

• Application transactions: the ability for smart contracts to execute transactions on directly on chain.
• App cost pooling: larger contract size, by combining the budgets across an application group.
• Increased account smart contract limit to 50
• More smart contract opcodes to improve composability (inner transaction references, verify ECDSA, log, and others)
