Description

Our priorities for the third quarter of 2026 are:

  • Completing #2530, the Final Boss of C++23 features
    • No promises yet, but @Codiferous is almost done with his compiler work, and I'm expecting to work on the library side in July
  • Implementing LWG issues
  • Getting ready to accept contributions for C++26 features (we are not yet accepting them)
    • Write Contribution Guidelines (finally)
    • Improve automated Copilot reviews
    • Overhaul bloated test matrices
  • Keeping PR reviews flowing

If you have questions about our plans for this quarter, feel free to ask them here. (Compiler, IDE, etc. questions are off-topic.)

Research direction

Use the linked C++23, LWG, and C++26 project views as the starting point, then read the listed priorities and issue #2530. There is no named file, test, or single acceptance criterion here; first clarify which priority is available and what completion criteria apply.
