RISC-V organization developed many ISA extensions in past two years. The up-to-date specification status can be found here. I'll add missing instructions and CSRs. Following is the list to track unsupported extensions. I haven't reviewed every extension below yet. There is a chance that a extension doesn't add any instruction or CSR. However, it's still required to update the ISA parser.
