 Since May 13, 2026, NGINX Plus is published in two release types: Long-Term Support (LTS) and Continuous Release (CR).
 
-The NGINX Plus LTS release model is designed for mission-critical production environments. Each LTS release is supported for three years and receives security fixes and CVE mitigations without introducing new features. New features are delivered in [Continuous Releases (CR)](#cr) during the same annual LTS cycle.
+The NGINX Plus LTS release model is designed for mission-critical production environments. Each LTS release is supported for three years and receives security fixes and CVE mitigations without introducing new features. New features are delivered in CRs during the same annual LTS cycle.
 
 - **Cadence**: one LTS per year
 - **Patching model**: security/CVE fixes only, no feature changes
 - **Support window**: up to 3 years for each LTS release
 - **Concurrency**: up to 3 LTS versions supported at the same time
 - **Version format**: an LTS release has `0` as the second numeric component, for example: `PLS.37.0.0.1`. LTS updates increment the third component, for example: `PLS.37.0.1.1`.
 
-NGINX Plus Continuous Releases (CR) are published several times within an annual [LTS](#lts) cycle. Each CR contains the latest features and performance improvements. The CR cycle ends when a new LTS is released.

 ## Repository configuration options {#repo-options}
 
 By default, NGINX Plus repositories are configured to receive [Continuous Releases]({{< ref "/nginx/admin-guide/installing-nginx/installing-nginx-plus.md" >}}). To use LTS, update your repository configuration to point to the LTS package URL, replacing the default URL. You can choose one of the options during installation:
 
-- **Pin to current LTS only**: receive only security updates for this LTS, no CRs, no automatic update to next LTS; supported up to three years
-- **Pin to LTS track**: automatically upgrade to the newest LTS when it is released annually, no CRs.
-- **Default**: receive Continuous Releases within the current LTS release. No actions needed.
