- Weed out bugs in the numeric checking implementation
- Solve the problem with load_result/protected_function_result/unsafe_function_result being copyable and thus amenable to explosions. Fixes#995.
- Resolve the warning in sol::readonly. Fixes#1000.
- Looke into #1014. Not sure I can help there, honestly; looks like a mix up of multiply-loaded libraries and mixing the two.
