 **Server Base System Architecture** (SBSA) specification specifies a hardware system architecture based on the Arm 64-bit architecture.
 Server system software such as operating systems, hypervisors, and firmware rely on this. It addresses processing element features and key aspects of system architecture.

 ## SBSA - Architecture Compliance Suite
 
 SBSA **Architecture Compliance Suite** (ACS) is a collection of self-checking, portable C-based tests.
-This suite includes a set of examples of the invariant behaviors that are provided by the [SBSA specification](https://developer.arm.com/documentation/den0029/h/?lang=en), so that implementers can verify if these behaviours have been interpreted correctly.

 Most of the tests are executed from UEFI Shell by executing the SBSA UEFI shell application.
 A few tests are executed by running the SBSA ACS Linux application which in turn depends on the SBSA ACS Linux kernel module.
 The tests can also be executed in a Bare-metal environment. The initialization of the Bare-metal environment is specific to the environment and is out of scope of this document.
 
 ## Release details
- - Code Quality: REL v7.2.0 BETA-0
- - The tests are written for version 7.1 of the SBSA specification.
+ - Code Quality: REL v7.2.1
+ - The tests are written for version 7.2 of the SBSA specification.
  - For complete coverage of the SBSA rules, availability of an Exerciser is required for Exerciser tests to be run during verficiation at Pre-Silicon level.
  - For complete coverage, both SBSA and BSA ACS should be run.
- - The SBSA specification compliments the [BSA specification](https://developer.arm.com/documentation/den0094/c/?lang=en).
+ - The SBSA specification compliments the [BSA specification](https://developer.arm.com/documentation/den0094/d/?lang=en).
  - The tests can be run at both the Pre-Silicon and Silicon level.
  - The compliance suite is not a substitute for design verification.
  - To review the SBSA ACS logs, Arm licensees can contact Arm directly through their partner managers.
