 ## Release, Support Lifecycle and Support Policy
 
-NVIDIA supports both mainline and Extended Support Releases (ESRs). This support mechanism allows NVIDIA to maintain its desire to innovate, while providing stable releases as soon as it meets the architectural needs.
+NVIDIA supports both mainline and Long-Term Support (LTS) releases. This support mechanism allows NVIDIA to maintain its desire to innovate, while providing stable releases as soon as it meets the architectural needs.
 
-Consistent with this two-pronged approach, the mainline and ESR code branches are separate code bases. As such, issues and fixes in one branch are independent of the other. NVIDIA prioritizes the ESR branch for stability; any fixes on that branch focus on critical-impact security fixes and urgent bug fixes. This ensures that if you deploy an ESR release, you experience minimal disruption in day to day network operations.
