alt Hacker NewsThe current state of C++ next is maintained in what is called the C++ draft.
People (from the committee of experts appointed as national body representatives or invited experts) submit proposals which is essentially merge requests to make changes to the C++ draft. A proposal, by the way of it's changes, can either add a feature to C++ or remove features from C++ (kind of like deleted code).
In each C++ meeting, they have a vote for each proposal in the meeting and decide whether that proposal is allowed to act on the C++, thereby determining if the features gets in the draft (if the proposal was proposing a feature) or if the features is kicked out of the draft (if the proposal was advocating for removal of a feature).
Once a proposal has been voted in the draft, only another proposal can remove that feature from the draft.
Every 3 years, they seal the current state of the draft into a standard and send it for voting to the official ISO C++ committee of national bodies (different from committee of experts we mentioned above). And I think each national body has a veto. (that is the vote has to be unanimous, but not sure here).
At this point, first the National bodies can make comments where they can threaten to veto the standard if their comment is not looked at. Then, the committee of experts can either respond to the comment or follow the comment or do whatever.
The official committee (essentially national body members) then votes and can only approve or reject the standard in the whole. So, if they reject of example C++ next now, there will be no C++26.
The whole process from sealing to actual voting takes around a year or so. In the mean time the committee of experts starts working on the next c++ standard from the sealed state forward without waiting for the committee to ratify the current one.
What Bjarne is doing is that he was threatening to get a national body to veto the proposal so that there is no C++26 at all. So, his point was, either accept his paper as it is (which calls for removal of contracts from the C++ draft before it goes to committee of national bodies), or he probably gets US or Denmark or some NB (not sure which) to vote no on the C++ standard (when it eventually goes to the committee of national bodies with the contracts in it, kind of like throwing baby with the bathwater).

Thanks for this! I vaguely knew most of it but it's great to hear more details.
I think that my misunderstanding here is because I thought that the vote in Croydon back in March was the last chance to veto things, but re-reading https://herbsutter.com/2026/03/29/c26-is-done-trip-report-ma...

So yeah, I guess in most cases this final ballot is a rubber stamp (not a bad thing, actually, I'd argue it's the way it should be) but maybe this time it is not.
> And I think each national body has a veto. (that is the vote has to be unanimous, but not sure here).
No veto. Every P-member has a vote (abstain/approve/disapprove). Whether C++26 gets published is decided by numerical consensus.
This does sound a lot like there's a real risk of C++ imploding, in some form or another. (Arguably, it has been in that state for a while now.)
I personally agree that contracts probably shouldn't be in the standard, but this whole situation looks like a mess.
I recently watched the c++ documentary and it was super sobering in how it mirrors this description of the process. https://herbsutter.com/2026/06/04/c-the-documentary-released...
The true goal of C++ is the self-preservation and funding of the ISO Committee specification “engine”, while compilers are merely an accidental by-product.
Once you see this then suddenly a lot of odd behavior makes sense. For example the committee can’t break ABI because then the old companies wouldn’t fund the new c++ standard, but would fund a committee that maintains/forks the old thing. The complexity / bureaucracy also provides jobs for those involved in many ways including writing new books every year and or consulting.
While end consumers might really care about compile speed, modularization, security, and all of the things modern languages give, that is secondary to keeping the committee alive.
Younger me would be like, oh no this is horrible someone will fix this! Older me is more sober and understands that once a system is up and running it will continue as is (this being an example of Pournelle’s Iron Law of Bureaucracy). Security by the way of migrations to Rust is causing what the committee sees as the first real threat to its existence as its patrons start adopting more and more Rust. As a result the committee is proposing to break compatibility as a means to keep them around just a little longer. Note: Actually fixing the security issues is not important only giving enough for sponsors to not leave so we will see what actually happens.
