In the case the process is already in place ... Travis is routinely testing against v20.02. If we wanted to make this abundantly clear we could add a note/section explaining the process to guides/contributing/abi_versioning.rst ? So I think we need two other policy additions. 1. Fiona is clear, that we need a note on the policy document to cover the version numbering error that was made in DPDK 19.11. Bruce's commit (f26c2b39b271cdcd857ba518c5e48c78cb1c30af) on the subject, explains it very well ... 2. We also need to merge "doc: alias to experimental tag for stable apis"
