Description

Currently both Error and Warning are displayed in red in the terminal so errors do not stand out and warnings are not easy to discern from errors. I haven't checked, but I suspect that the info messages added in #11606 are red too.

Issue

The "Full Example" of using @truffle/contract to interact with contracts should include an example of listening to an event with a filter.

As a first-time LND user,

Problem

We still have some python2.7 in the following scripts. Python2 is EOL

ci/dependabot-pr.sh
system-test/automation_utils.sh

Proposed Solution

Port them to Python3

A parametrized option to set the blocksize would be useful to experiment with. As quorum is used in a private setting I think this option should be available
