New issue by paper42 on void-packages repository

https://github.com/void-linux/void-packages/issues/36387

Description:
Some projects have two sources for $changelog - one from the master/main branch for rcs, alphas, betas and first releases in a series and one from a maintenance branch for patch releases. This is mostly visible in GNOME projects, but other projects also use this strategy.

Sometimes the maintenance branch doesn't exist until it's needed which means that if we decide to use the maintenance branch for the changelog, it will be a 404 link until they create the branch (#36353).

This can be solved with allowing multiple entries in the $changelog field.
