+Subject: [PATCH] Set C++ standard (to C++14) using CMake
+
+Not adding the -std flag broke builds with GCC 11 until the code was
+fixed up recently. This should prevent this sort of thing from
+happening in future. It also ensures that the compiler is actually new
+enough.

+Subject: [PATCH] Fix bad channel count handling with libsamplerate 0.2.0
+
+Since libsndfile/libsamplerate@26d92c369394bcd0b0cea488890edce1a0d757d5,
+initialising libsamplerate with 0 channels or less causes a SIGABRT. We
+therefore need to handle this in the C++ wrapper classes.
