Binary releases as in a sepparate/propietary app that's only shipped as
a binary? (not built with buildroot and/or not able to share the source).
I'm not asking because of any licensing crazyiness, it's perfectly
valid, just want to understand the scenario.

Well the binary compatibility isn't an issue for typical buildroot
scenarios, that's why i'm asking what i asked.
The changelog entry is a typical linux distribution issue where you just
upgrade individual components when necessary.
That's usually not what buildroot is about, you're building a root
filesystem (in simplified terms) so your upgrade path is usually a
complete image upgrade, call it firmware, flash or disk image.
Hence ABI compatibility doesn't matter.
Understand i'm hesitant to bump libnl this close to the release unless
there's a really pressing issue - libnl bumps usually break packages
subtly and this requires testing.
And it also breaks every other release with varying linux headers when
new features are introduced (like CAN support).
