 * Building GnuPG 2.1: GnuPG 2.1 is the latest GnuPG version but as with all 2.x versions it has several dependencies, which make building it a bit more difficult.  Here are some notes.

 * API checker:
   [[http://upstream-tracker.org/|Upstream-Tracker.org]] checks ABI/API changes for some libraries like [[http://upstream-tracker.org/versions/gpgme.html|gpgme]],
   [[http://upstream-tracker.org/versions/libgpg-error.html|libgpg-error]],
   [[http://upstream-tracker.org/versions/libgcrypt.html|libgcrypt]].

   Note that the tools can't necessary decide whether something is an ABI or API
   change.  The output should be used as a hint to look for whether there
   might be a problem.  We are not aware of any broken API or ABI
   contracts for the listed libraries.
