Preemptive note for those who are concerned that ISO charges
money for the final official text of the standard [...] the
final text where ISO asserts copyright.
"Why aren't ISO standards free?
ISO standards cost money to develop, publish and distribute. Someone has to pay. The current system whereby users are requested to pay for the standards they use, not only sustains the development process but also, very importantly, ensures that the balance of independent vs. government, private vs. public interests can be maintained."
Most of the people that actually work on the standards are paid for their work by companies in the relevant field.
If the organization was running anywhere close to correctly, their costs would be limited to typesetting, some organizational work for meetings, and bandwidth. All of which could be trivially borne by modest contributions of the governments and corporations involved.
Anyway, this is off-topic as all ISO standards cost money and have for a long time now. I'm glad C++ has a new standard. The boost additions are great and make C++ even better than it was.
