If you choose to migrate, be prepared for some code adjustments. Syntax differences between AC5 and AC6 can require modifications to assembly code, inline assembly, and compiler-specific attributes.
It is highly mature, with virtually all bugs found and mitigated over years of usage.
The official Arm download site sometimes experiences issues. As one developer reported in the Arm Community forums, “I’ve been trying to download it from the arm dev hub for legacy downloads multiple times but I keep getting error messages”.

Arm Compiler 5.06 update 7 is the final maintenance release of the version 5 series. It is highly sought after because:

In the world of embedded systems development, stability is often prioritized over the latest features. While ARM has moved forward with the ARM Compiler 6 (based on LLVM), many developers working on older ARM Cortex-M or ARM7/ARM9 projects continue to rely on the robust and highly optimized ARM Compiler 5 (AC5).
Downloading the binaries is free, but compilation requires a valid license. Update 7 checks for:
Navigate to the official or the Keil Product Downloads page.
To install the update, follow these steps:
Many medical, automotive, and industrial projects are qualified on specific compiler versions; Update 7 includes the final roll-up of stability fixes for these environments. Keil MDK Integration: If you choose to migrate, be prepared for
ARM Compiler 5 is not "freeware." To use the downloaded Update 7 version beyond a restricted code size, you must have a valid or Keil MDK license. If you are a student or hobbyist, check for the "MDK-Lite" version which includes the compiler with a 32KB code limit. Conclusion
To help you get your environment up and running smoothly, tell me:
Altered compilers can introduce silent code generation bugs into your firmware, causing unpredictable hardware failures.

Arm Compiler 5 was historically provided as part of Keil MDK licenses. For many users, especially those with a valid MDK license, AC5 can be used without additional cost. However, commercial use may require proper licensing. Check Arm’s official licensing terms for your specific situation.
