https://github.com/wavesplatform/Waves/releases/tag/v1.5.0 #WAVES 1.5 on stagenet! State snapshots are distributed instead of blocks, which greatly increases the network capacity as a whole. In the Waves 1.5 protocol, a block generator distributes state snapshots to the blockchain network, including changes in blockchain state like balances, account data, scripts, and token parameters resulting from transactions in the block. If a generating node detects a mismatch between a received snapshot and a block, it can challenge the block and earn a reward. Other nodes can operate in a light mode, which speeds up block processing by using pre-validated state snapshots. The light mode can be enabled or disabled with the waves.enable-light-mode setting. Additionally, new fields like "state_hash" and "challenged_header" are added to block headers, and an "attachment" field is introduced for orders as part of Exchange transactions.
