-    changes:

-      called “RISC-V CRDs (Certification Requirement Documents)”
-    - Change MC100 Unpriv ISA spec from

-      former isn't ratified by the latter is the oldest ratified version.
-    - Added requirements for WFI instruction
-    - Added requirements related to msip memory-mapped register
-  - revision: "0.6"
-    date: 2024-07-11
-    changes:
-    - Supporting multiple MC versions to support customers wanting to certify existing microcontrollers not using the latest version of ratified standards.
-    - Changed versioning scheme to use major.minor.patch instead of 3-digit major & minor.
-    - Added a table showing the mapping from MC version to ISA manuals.
-    - Reluctantly made interrupts OUT OF SCOPE for MC100 since only the CLINT interrupt controller
-      was ratified at that time and isn’t anticipated to be the interrupt controller used by MC100 implementations.
-    - Clarified MANDATORY behaviors for mie and mip CSRs
-    - Removed canonical discovery recipe because the OPT-* options directly inform the certification
-      tests and certification reference model of the status of the various options. Also, canonical
-      discovery recipes (e.g., probing for CLIC) violate the certification approach of avoiding writing
-      potentially illegal values to CSR fields.
-    - Added more options for interrupts
-    - Moved non-microcontroller content in this document to a new document called “RISC-V Certification Plans”
-  - revision: "0.5"
-    date: 2024-06-03
-    changes:
-    - Renamed to “RISC-V Microcontroller Certification Plan” based on Jason’s recommendation
-    - Added mvendorid, marchid, mimpid, and mhardid read-only priv CSRs because Allen pointed out
-      these are mandatory in M-mode v1.13 (probably older versions too, haven’t looked yet).
-    - Added table showing mapping of MC versions to associated RISC-V specifications
-  - revision: "0.4"
-    date: 2024-06-03
-    changes:
-    - Added M-mode instruction requirements
-    - Made Zicntr MANDATORY due to very low cost for implementations to support (in the spirit of minimizing options).
-    - Removed OPT-CNTR-PREC since minstret and mcycle must be a full 64 bits to be standard-compliant.
-  - revision: "0.3"
-    date: 2024-05-25
-    changes:
