- Add a flag to allow size_t(-1) and similar shenanigans (SOL_ALL_INTEGER_VALUES_FIT)
- Half-fix, but not fully, for #1183, #1072, #1038, #965
- Fix#1126
- Prepare for #1061
- Not at all type safe: there should be some investigation into making it less unsafe to work with these things (albeit it looks like it would cost +1 pointer to serialize a string name for each callable in Lua, at LEAST)
- Must be opted into - see the documentation
- Fixes#1015
- A few drive-by fixes here and there
- New configuration test harness with CMake
