Scheduled

We are upgrading our zkSync Mainnet and Testnet infra to v29.19.0. During the maintenance window, brief interruptions to RPC availability may occur. This release includes a bug fix for call trace data and prover enhancements.

## RPC Changes

**`debug_traceBlockByNumber` — fixed**
Call traces were missing from block trace results. This fix ensures complete trace data is now returned for all transactions in traced blocks.
