"""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.
