PKEuS c96f85e2a2 Refactorization: Implemented rValue-reference- and "const char*"-overload to make_container::operator<< 2015-08-11 14:05:01 +02:00
PKEuS ebfdacb0d3 Introduced .cfg file format version to 2 (to prevent older cppcheck versions from failing silently when reading them), because 5b287fc849 introduced a backward-incompatible feature.
Increased format version of std.cfg, which is the only cfg file that makes use of the new backward incompatible feature.
