-There are two mailing lists for sigrok/libsigrokdecode:
+libsigrokdecode is licensed under the terms of the GNU General Public License

+The protocol decoders (PDs) included in libsigrokdecode are an integral part
+of the shared library (they are not merely external "plugins", they are not
+external programs that libsigrokdecode calls via fork/exec, they cannot
+function standalone without libsigrokdecode at all, the PDs and the rest of
+the libsigrokdecode codebase share data structures and make function calls
+to each other). Thus, since the PDs are part of the library, they are also
+licensed under the terms of the GPLv3+.
+
+While some individual source code files are licensed under the GPLv2+, and
+some files are licensed under the GPLv3+, this doesn't change the fact that
