The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This software lifecycle support statement describes the support timeline and support guidelines for Cisco Ultra Cloud Core (UCC) software products.
Cisco UCC Software Release Delivery
Cisco is introducing a modern software product lifecycle model with specific EoL guidelines for all Cisco UCC software dot-dot-zero releases (i.e., cn5G-YYYY.xx.0 & cn5G-YYYY.xx.h0). These EoL guidelines apply to all UCC PIDs. This bulletin may be updated or additional EoL announcements may be released for other UCC components as necessary.
End-of-Life Guideline Definition
All Cisco UCC software releases adhere to the guidelines presented here.
● Customers are encouraged to upgrade to the most recent UCC software release as soon as it becomes available. Newer versions of software consistently enable the delivery of relevant data driven insights, leading you to critical software innovations that reduce infrastructure and business risk, and deliver a better software experience.
● UCC customers with an active Subscription or active Cisco Support contract that includes upgrades are eligible to download the latest software release from https://software.cisco.com/.
● No release-specific EoL notices will be issued.
