Hi @naseemkullah
What about scraping multiple targets? Looks like this is no longer supported, at least not in the way it used to work. I suppose we need to adapt to those change before moving forward.
Any ideas?

[naseemkullah]

True.
I agree we should adapt these changes, probably bump the major version of this chart. I think all this entails is accepting a single value for redisAddress rather than a list of values (unless I am missing something?), and adding an Upgrading section to this chart to forewarn about the breaking change, referencing this PR as well as the relevant section in redis_exporter's README.
