— In the Emulation API and Pending API, transaction chains are now emulated more accurately.
Previously, all transactions in a chain were emulated for a single block. Now, the emulator distributes transactions across different blocks (for example, an inter-shard message will occupy several blocks).
This allows for more accurate prediction of transaction order and results, as well as approximate timestamps and lt values for transactions, which makes it possible to estimate approximate execution times.

address_book and metadata.
