What do you do when your changelog starts to get really big over several years?

I've noticed my changelog has grown to several thousand lines. While I don't find this problematic from an editing perspective (I typically work at the top of the file, and the reference links at the bottom are automatically managed), I was surprised to find no explicit guidance in the keep-a-changelog FAQ addressing this situation.

I'm curious about community standards regarding pruning historical entries. Is there value in retaining very old release information, such as a v1.0 from 5+ years ago? I'd appreciate insights on best practices and whether there's a consensus on how to handle increasingly lengthy changelog files.
