ergo-lib-v0.28.0

Breaking Changes

ErgoStateContext::new now requires Parameters for blockchain parameters. For consensus-critical applications it is important that Parameters represents the latest state of the blockchain. For most users however, using Parameters::default() will be sufficient as this will not affect signing:

- let state_context = ErgoStateContext::new(pre_header, headers);
+ let state_context = ErgoStateContext::new(pre_header, headers, Parameters::default());

Added

• Support for validating transactions using sigma-rust (without costing), using TransactionContext::validate: https://docs.rs/ergo-lib/0.28.0/ergo_lib/wallet/tx_context/struct.TransactionContext.html#method.validate
• Performance improvements for ErgoScript interpreter, which should improve signing and validation times for complex scripts and large transactions significantly
• Support for creating transactions that spend storage rent boxes
• WASM/C bindings now include more functions #745 #742 #751
