Recent updates:

- Clients are now allowed to skip nonces. This is optional, and can be done by setting the SkipNonce field in L2TxAttributes to 1. We still require the next nonce to be higher than the previous, and lower than 2^47-1. SDKs support will be rolled out later this week
- The number of available sub-accounts has been increased from 8 to 64 on the highest staking tier, or fee credits equivalent
- The builder tier is now available, allowing 240K weighted requests on read endpoints, at no extra cost. You can reach out via Discord support channels to be part of the program
- The order_book and ticker WebSocket channels now include last_updated_at, a committer-level microseconds timestamp
- liquidation_price is now correctly displayed on WebSocket channels that return position data
