Juniper provides this document as a means to help customers and Juniper manufacturing select a Junos software version that aligns with their deployment needs. The releases listed below have performed well for the general population, but note that due to the uniqueness of our customer network deployments to include areas such as design, traffic patterns/flows, and specific usage of features and functionality, Juniper recommends that all customers A) read the associated Release Notes to understand how features, functionality, fixes, and any known outstanding issues may apply to your specific network and applications, and B) test and certify the suggested code version(s) to ensure they will perform as expected in your network.
This article applies to the following devices:
Juniper Mist cloud features such as Wired Assurance, WAN Assurance, and AI-driven switch management depend on supported Junos OS releases on the managed Juniper devices. The Junos Software Versions – Suggested Releases to Consider and Evaluate knowledge base article provides a current list of recommended Junos versions by platform (EX, QFX, SRX, MX, ACX, PTX) that have broad field experience and JTAC support guidance. For switches and firewalls managed by Mist, the suggested releases in this list should be used as target versions when planning firmware upgrades or initial installations. These version recommendations are referenced directly from Juniper Mist Supported Hardware documentation and inform minimum and recommended firmware baselines for Mist Assurance features. Before upgrading, review the Release Notes for each suggested Junos version to confirm that the specific Mist capabilities you need are supported.
For other Junos devices, refer to the Release Notes and the Alerts column on the Download Software pages.
