vNext Planning

Salvage The Old vNext Branch

• Multithreading overhaul
• Iterator debugging overhaul (doubly-linked iterator chains, no proxy allocations)
  • Still need to overhaul deque and vector<bool>
• Remove /clr:pure
• Flat C exports
• Remove <hash_map>, <hash_set>
• Remove tr1
• Other changes? (vcplatform?)

Major Overhauls

• <regex>
• <deque>
• <unordered_map>, <unordered_set>
• iostreams floating-point

More Work

• vNext Issues
• TRANSITION, ABI comments
• Consolidate satellite DLL and import LIB code back into the main DLL
• Drop Vista support; Win7 must be the minimum platform
• Remove _app DLLs
• Increase x86 to /arch:SSE2?

Compiler Work

• Remove /Za (effectively superseded by /permissive-)
• Remove /Zc:wchar_t-
• Increase minimum Standard version to C++17 or C++20?
• RTTI overhaul?
• EH overhaul possible? (Table-based x86?)
• Fix Empty Base Class Optimization
• Avoid ABI-breaking options (e.g. /vd2, /vmg, /J)
