+     not be able to handle version 2 files, but new libsigrok versions can
+     handle both version 1 and version 2 files. New libsigrok versions will
+     always write/output version 2 files.

+   - 'struct sr_session' is now opaque (contents shouldn't be used directly).
+   - Please see the Doxygen API documentation for further details.
+ * Build system:
+   - Switch to a non-recursive automake setup (fewer files, faster builds).
+   - configure: Clearly mark required and optional libs.
