bnb-chain/bsc - v1.6.3

Published: Nov 6, 2025

Release Summary

This release delivers key bug fixes and improvements focused on enhancing node stability and performance.

Key Improvements

A critical update resolves an issue where a node could become stuck and stop processing new blocks. This situation could occur if a node received a new block (e.g., block N+1) before it finished importing a previous, large block that took a long time to execute. This fix ensures smoother and more reliable block synchronization, especially on networks with variable block processing times.

Additionally, a recent change to the Parlia consensus engine (the "nano check") has been reverted to enhance stability.

Bug Fixes

This version addresses several bugs, including:
