Algorand updates MainNet and TestNet to Go-Algorand 3.21.0 with dynamic round times and new AVM opcodes
Algorand updated both MainNet and TestNet to version 3.21.0 on January 9, 2024. The release introduces dynamic round times, which shorten average round durations, and adds new opcodes for the Algorand Virtual Machine. The consensus protocol upgrade also requires updates to the indexer and conduit.
Dynamic round times allow the network to adjust how quickly rounds close, rather than using a fixed interval. The new opcodes extend the instruction set available to smart contract authors on the AVM.
