"""Backwards compatibility functional test
Test various backwards compatibility scenarios. Requires previous releases binaries,
see test/README.md.
Due to RPC changes introduced in various versions the below tests
won't work for older versions without some patches or workarounds.
Use only the latest patch version of each release, unless a test specifically
needs an older patch version.
