Once the RISC-V GCC toolchain and the Spike simulator have been updated to version 0.10, the same can be done with Ara.
In terms of microarchitectural changes, RVV 0.10 deprecates the SLEN parameter, the striping distance being set as being always equal to the vector length VLEN. Current Ara already takes this into account, since it considers that SLEN = VLEN.
Other RVV-upgrade changes include the implementation of extra floating-point instructions, and encoding changes with a few vector CSRs.
