d01c116764 cleanup: make it more clear that assert and uint32_t increment both only exist if NDEBUG is not defined
58fac53429 refactor: Add a `bin_unpack_bin_max` for max-length arrays.
6be29f01e5 chore: Add more logging to loading conferences from savedata.
1195271b7f Fix inversed return values
82276ef5ac cleanup: Fix GCC compatibility.
