Cpp features blocked by version
From The Battle for Wesnoth Wiki

Summary
This is a listing of C++ features that would be useful to have but can't yet be used. The Feature column is the language or standard library feature (https://en.cppreference.com/w/cpp/compiler_support is a good reference). The Benefit column is what having this feature will allow to be done. The remaining three columns are for the minimum requirements for the feature to be available on each platform. The minimum requirements can be anything - Visual Studio version, compiler version, OS version, etc.
Benefits that don't justify version increases
This is a non-exhaustive list:
- Improving compile speed.
- Pretty much any standard library feature that we can just as well get through boost or other means.
Benefits that do justify version increases
This is a non-exhaustive list:
- Required to fix a bug that has a significant impact to players.
