Thank you for taking the time to report this bug and helping to make Ubuntu better.
Since you mention version 0.3, I assume this is the version packaged in Ubuntu Zesty (0.3+17.04.20161219-0ubuntu1). I can confirm that /usr/lib/x86_64-linux-gnu/pkgconfig/libcontent-hub.pc in libcontent-hub-dev in this version indeed contains "Version: 0.2.0" which seems like a mismatch.
