What can I do, as an end user, when a testing package on the gentoo tree has been outdated for a while? I know I can just download the tar file of the source code and compile it myself, but I wonder if there is anything else I can do to help on the gentoo repos.

For example Waybar has a 0.9.18 version available upstream, but not on gentoo. This version was released about a month ago, and includes compatibility for dwl. It's not really an issue for me, since I compiled the 0.9.18 version manually, but I'd like to know if there is anything I can do to help.

Sorry if I'm not using all the correct terminology; I'm new to gentoo.
