There is definitely a breaking archive format change in basic_binary_iarchive.hpp:110 (1.42.0) - collection sizes serialized as std::size_t rather than unsigned int.
The code in question is: void load_override(serialization::collection_size_type & t, int){ if (this->get_library_version() < 6) { unsigned int x=0; * this->This() >> x; t = serialization::collection_size_type(x); } else { std::size_t x=0; * this->This() >> x; t = serialization::collection_size_type(x); } } This indicates that if the serialization library version is less than 6, then read the collection count as an unsigned int from the file. Otherwise read the collection count as an std::size_t from the file. Thus, backward compatibility is maintained through this change. Robert Ramey
