I can't even imagine the amount of work that goes into producing a specification like this, BUT... I wish there were a reduced price option for individuals. I just can't justify spending USD 200 on getting a copy for myself. I'd love to have a copy so I don't have to rely on second-hand sources like websites and implementation details from STL maintainers on Reddit or Stack Overflow.

Do I really have to pay for a pdf of the standard? (sorry I just don't see anyway else to download the pdf)

Just go to https://github.com/cplusplus/draft for drafts. Choose a draft version that is produced right before the actual date of standardization and there are only very minor differences between the draft and the real deal.

You can build the pdf yourself from the LaTeX source: https://github.com/cplusplus/draft Or get the latest public draft from https://wg21.link/standard Or an html version: http://eelis.net/c++draft/

Thanks. I just like having an official (not draft) copy. I'm a nerd.

I just built from the LaTeX source and it's 32 pages longer than the public draft in the second link from 6 weeks ago. Maybe just additional descriptive language, but...

Someone will upload it on libgen within a few days

That is illegal.

Awesome news. gcc has had experimental support for C++17 for a while now, any idea on a potential time frame for it to move from experimental to final standards compliant?

The reduced price option for individuals is that you just look at the last working draft, which is always published for free for all ISO standards and is almost equivalent to the final product. The only reason anyone cares about the officially published standard is if you're a compiler vendor who wants to know for sure that your product is standards compliant, which is why the cost for the no-draft versions is what i…

The almost equivalent is always the scary part. Is there a guarantee that there is no technical difference between the draft and final standard? From your reply, it seems, it is intentionally not specified what exactly are the differences to force compiler vendor to buy the standards. But then the one using a draft is always scared there is one thing different which he has not looked into and this is causing problems somehow.

C++17 is a slight disappointment, I hope C++20 will be the real deal - concepts could really be a game changer and move semantics needs more fixes :/.

It still is pretty sweet for polyglot developers.

Reading https://github.com/cplusplus/draft, it seems you had to generate figures from their dot source.

If so, the result may depend on your installation (probably even if you use the same version of GraphViz but a different OS and/or set of fonts), and that can affect pagination.

Also, are you sure you built for the same paper size? A4 vs US letter could explain the difference.
