Hi there,

Please do not post comments like: "Any update on this?" or "When will this be fixed?".

If you're asking because you want to know if there's been some progress, then please know that we work in the open in this repo. If there was an update to this Discussion or Issue, you would see it already. So please don't ask "just in case".

If you're asking because you want to get our attention, then please don't do that either. It wastes maintainer time and pollutes the repo. You're welcome to fix issues yourself, hire someone to help you, or wait for someone else to do the work. You're not welcome to post the equivalent of "Hey, someone else should really do something about this".

If you are a paying Mend.io customer, contact your support or customer success representative, and tell them this issue is important to you.

We expect everyone to follow these rules, no matter if you use the free tiers, or are a paying Mend customer. Please read our Code of Conduct, how we prioritize work to learn more about how we prioritize what to work on.

Thanks, the Renovate team
