$IOST is scheduled to activate new mainnet rules at block 480,080,000. The project estimates the block will arrive around 23:45 UTC on Nov. 10, though the timing depends on how fast blocks are produced.

One change affects transactions that make several contract calls: if a subcall fails, the entire transaction is rolled back. The upgrade also changes when events are emitted, so apps only receive them after a successful commit. Mainnet node operators need v4.10.0 before activation to stay compatible with the network.
