Hello,
In debian, during the build of a package, we have a tool checking if
symbols are removed from shared librearies.
With the 2.5.2 release, I get the following output:

Is that expected that these 4 symbols have been removed?
Yes. This corresponds to the changelog entry:
- Revise function hiding technique to better protect audit ABI
All functions missing are internal to the audit libraries and could cause
symbols collisions or worse if people start using them even though they are
not declared in the library headers.
