This specification is written in collaboration with the development communities of the major open-source toolchain and operating system communities, and as such specifies what has been agreed upon and implemented. As a result, any changes to this specification that are not backwards-compatible would break ABI compatibility for those toolchains, which is not permitted unless for features explicitly marked as experimental, and so will not be made unless absolutely necessary, regardless of whether the specification is a pre-release version, ratified version or anything in between. This means any version of this specification published at the above link can be regarded as stable in the technical sense of the word (but not necessarily in the official RISC-V International specification state meaning), with the official specification state being an indicator of the completeness, clarity and general editorial quality of the specification.
