Exported symbols removed in 2.5.2

[Laurent Bigonville]

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:

--- debian/libauparse0.symbols (libauparse0_1:2.5.2-1_amd64)

Is that expected that these 4 symbols have been removed?
