Changelog

July 2025

v0.18.0

This release introduces significant updates, with the most notable being a complete rewrite of the cluster mode. The new leaderless architecture ensures that all servers in the cluster are equal, eliminating the need for a designated leader. This change improves both availability and performance, allowing the system to continue functioning seamlessly even if connections between nodes are interrupted.
