Release notes is missing feature: tracing-subscriber 0.3.16

Bug Report

For this release: https://github.com/tokio-rs/tracing/releases/tag/tracing-subscriber-0.3.16
I think the feature of keeping max N files with this PR: #2323
is missed.

I just noticed this, because:
I was using v0.1.x branch in my cargo.toml, and it's been 8 months, so I've decided to check the release notes once more. After couldn't see the new feature in the release notes, I've decided to check commits, and then found out that with subscriber-0.3.16, this feature seems to be in the code for the commit used for this release. However, there are no mention of this feature, nor the contributors in the release notes.

I probably confused myself. When I browse the files of commit that is used for 0.3.16 via GitHub UI, the changes of max_n_files are there in appender.
However, in the source-code in my project, they are not there.
Don't know how to interpret this 🤷

tracing-appender and tracing-subscriber are separate crates. The tracing-subscriber 0.3.16 release will not contain features added to tracing-appender.

We need to release a new version of tracing-appender before this change will become available.

Thank you for the clarification!
