The May 2026 WG21 mailing in five papers (pre-Brno, 116 total)
WG21 dropped the pre-Brno mailing in early May -- 116 papers, the largest pre-meeting mailing since the C++20 design crunch. Five papers are doing the heavy lifting for C++29's safety story (the headline axis named in P5000R1 'Direction for ISO C++29'), plus the coroutines-for-I/O work that finally got first LEWG review on the schedule. This is the table of contents for what wro.cpp will be tracking through to Brno (8-13 June).

C++ Safety State of the Union: May 2026
C++ in May 2026 has four conversations running at once: regulators (CISA, EU CRA) demanding memory-safety roadmaps; the committee fighting over how to respond (Hagenberg vote 19 profiles / 9 Safe C++ / 11 both); what actually shipped in C++26 (P2900 contracts, P3471 hardened stdlib, P2996 reflection); and what the industry actually deployed (Chrome MiraclePtr -57% UAF, Google's 0.3% perf-cost data, Apple libc++ safe-buffers). They don't talk to each other in public. This essay wires them. Pre-Brno (8-13 June) reading.

Revzin at C++Now: 'Reflection Is Only Half the Story' -- what generation looks like next
Barry Revzin's C++Now 2026 keynote (Mon 4 May, Aspen) landed the line the C++ reflection community has been circling for two years: C++26 reflection lets you OBSERVE -- the next question is what it looks like to GENERATE. The 90-minute talk is a tour of source-code-generation design space (macros, templates, Rust proc-macros, Swift macros, D mixins) and reads as the natural sequel to wro.cpp's whole 'Where this is heading' triptych framing.
