According to COINCU2, Ethereum programming language Vyper has released its v0.3.10 candidate version. This performance-focused release includes a codesize optimization mode, new Vyper-specific #pragma directives, Cancun's MCOPY opcode for some compiler-generated code, and O(1) performance selector tables.

The update introduces breaking changes such as adding runtime code layout to initcode, dropping EVM versions through Istanbul, and removing the Vyper signature from runtime. Non-breaking changes and improvements include O(1) selector tables, implementing bound= in ranges, adding an optimization mode to the Vyper compiler, and improving batch copy performance.

Vyper, a newer language for Ethereum development, was released in 2018. Similar to Solidity, it is a statically typed language with syntax resembling Python programming language. Vyper offers a high level of security for smart contracts due to its simplicity and fewer features compared to Solidity, making it less vulnerable to security threats. This makes Vyper a valuable tool for developers looking to build decentralized applications and write secure, efficient smart contracts on the Ethereum platform.
