* New upstream release. * Cryptographic signature verification: the upstream is providing a GPG signature that allows the tarball verification. Consequently: - Added the debian/upstream-signing-key.pgp file. - Added the debian/source/include-binaries to allow the debian/upstream-signing-key.pgp file use. - Removed the debian/source/lintian-overrides file. - Updated the debian/watch file. * debian/copyright: updated the upstream code copyright years. * debian/rules: removed triggers to avoid compiler-flags-hidden and dpkg-shlibdeps warnings, the last about useless dependencies. The upstream improved the source code.
