"""Backwards compatibility functional test
|
|
|
|
Test various backwards compatibility scenarios. Requires previous releases binaries,
|
|
see test/README.md.
|
|
|
|
v0.15.0.0 is not required by this test, but it is used in wallet_upgradewallet.py.
|
|
Due to a hardfork in regtest, it can't be used to sync nodes.
|
|
|
|
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.
