Valkey 9.0, the open-source, enterprise-ready in-memory data store, is scheduled for release on September 15, 2025. This release marks a significant milestone for the project, which was forked from Redis and is now governed by the Linux Foundation. Valkey 9.0 introduces a range of features aimed at enhancing operational safety, security, and network resilience.
Key features of the release include a safe shutdown mode to prevent data loss, unified auto-failover configuration for improved system stability, and native TLS certificate-based client authentication to meet the security and compliance needs of enterprise users. The addition of MultiPath TCP replication support is designed to ensure data consistency, even in unreliable network environments.
For developers, Valkey 9.0 brings new commands such as DELIFEQ to simplify distributed locking, along with other quality-of-life improvements. The release of Valkey 9.0 demonstrates the potential for open-source projects to deliver enterprise-grade reliability and performance without the licensing restrictions and vendor lock-in associated with proprietary software.
