I’m quite familiar with much of the content of C++ 2011 as it represented a welcome and long desired step up in C++ language capability.
I’m less clear on the changes that live in the 2014 and 2017 incremental updates (smaller and more tightly focused) and the upcoming work that will feed into the next release.
Getting on top of this is becoming more important as I’m back in the C++ world and while almost everything should support C++ 11, the later iterations may be missing or fragmentary.
I have pulled the draft PDF file for 2011, 2014 and 2017 and grabbed the github source for the standard(s). These are quite useful, but seriously deep waters if only the changes are of specific interest. Interesting pointers on where to buy the official docs here with the 2017 version from ANSI at just over $100.00. The current working draft appears to be on github here. I may take a shot at building that into a readable PDF at some point…
I am also rather interested to see what is in boost these days. Back in the visual studio 2010 era, the TR1 content that eventually fed into C++ 11 was one of the bigger draws…now that is part of the core tools in general so I’m expecting a new range on interesting bits. The seem to have a github repo here.
And here is the C++ 20 page. Interesting that 20 looks to be much more like 11 than 14 and 17 (which were small tweaks).
