As already announced, CppCon 2021 will kick off on Monday, October 25 with Bjarne Stroustrup delivering the opening keynote live in person in Aurora, Colorado, USA.
We’re happy to announce another plenary talk: Herb Sutter will be there live in person to deliver a brand-new talk about post-C++20 C++ language evolution. Here is his talk description:
Extending and Simplifying C++: Pattern Matching using is and as
C++20 is a unique historic milestone: the first edition of Standard C++ that’s “D&E-complete,” with essentially all of the features Bjarne Stroustrup outlined in The Design and Evolution of C++ for C++’s evolution. That doesn’t mean evolution is done, however, and work continues on adding a few more important features in C++23 and beyond, including reflection and pattern matching.
In this talk, I’ll show the C++ pattern matching libraries and language proposals we’ve considered, and present my own contribution that builds on them. My paper has two major aims: (1) to make the syntax clean and regular, and avoid inventing a little sublanguage that works only inside “inspect”; and (2) to make it generalizable so we can use it consistently throughout the language, because matching a pattern is a broadly useful feature that ideally should not be limited to “inspect” only… for example, we would love to express patterns in “if” and “requires” conditions too.
I hope that the most important contribution is that, if we add pattern matching in a way that also provides general “match” and “extract” support throughout the language in the form of generalized “is” constraints and “as” casts, the net result is that we can actually simplify C++… yes, even as we add new features and more expressive power. How can that be simpler? By letting programmers directly express their intent where they have to express it indirectly today, by making the language more regular with fewer special cases to learn, by unifying the syntax of existing standard library features that today have a gaggle of different and divergent styles (e.g., variant, optional), and by providing one general and expressive way to use patterns cleanly throughout C++.
Registration is now open for what will certainly be one of the most memorable CppCons ever this October 24-29. Register today!
Tickets are now available for both online attendees and in-person attendees who are vaccinated, with the goal of opening registration further as we all learn more about what will be safe.
The deadline for Main Program submissions has passed with a near-record number of submissions!
A peek behind the curtain for those of you that have not been part of the submission/review process: Each submission receives written evaluations by several members of the 
Our feeling is that all submissions, from the weakest to the strongest, can be improved in some way and comments that we’ve received from submitters (both those that have been accepted and those that have not) let us know that submitters appreciate thoughtful, constructive comments.

Most of the classes feature two days (onsite) or three days (online) of class instruction and all feature hands-on opportunities to improve your programming skills.
CppCon 2021 will kick off on Monday, October 25 with Bjarne Stroustrup delivering the opening keynote live in person in Aurora, Colorado, USA. This is Stroustrup’s first in-person talk in North America since C++20 was completed, just before the pandemic lockdowns began. His talk connects C++’s roots with all the things that make C++20 a historic milestone – it’s not only the biggest release of C++ in a decade, but also the first edition of Standard C++ ever that is “D&E-complete,”containing all of the features (except only unified function call syntax) that Stroustrup described a quarter-century ago in 
C++20: Reaching for the Aims of C++
Emery Berger is a Professor in the College of Information and Computer Sciences at the University of Massachusetts Amherst, where he co-directs the PLASMA @ UMass lab. To fully appreciate the work that Emery has done and the academic honors that he’s received, you really need to read 
Each session aims to present time-tested guidelines that are aligned with mainstream C++ and broadly useful across many industries. This accounts for the lack of any Back to Basics sessions on Concepts, Coroutines, or Modules — all big topics in the zeitgeist this year, but also topics where best practices are still hazy and implementations are still immature. Attendees seeking information on cutting-edge features of C++20 will find plenty of what they seek in CppCon 2020’s main conference program.
Here’s a sneak peek at this year’s Back to Basics lineup. The precise order of these sessions hasn’t been determined as of this post; we may shuffle them up a bit. We’ve also reserved space on Friday for a “closing track keynote” which has yet to be announced.

Most of us value the experience of having casual conversations with smart, knowledgeable C++ programmers, particularly when a new version of Standard C++ is out. In a year in which these opportunities have been severely reduced by a combination of working at home and the cancellation of in-person events such as conferences and user group meetings, we appreciate the in-person experience all the more. CppCon, one of the best C++ in-person experiences of the year, is needed this year more than ever and we are excited to be bringing it to you.
Of course, we can only do this if it is safe to do so. We are monitoring the situation closely and will hold the event only if it is safe to do so and only in a manner that is safe. We are working very closely with our venue, the Gaylord Rockies, in planning the event. They have selected Vanderbilt University Medical Center as their 
Because we must cap our attendance (we don’t yet have an exact number, we are still working that out), we are looking at the possibility, for the first time with CppCon, of selling out the conference. If you’d like to attend, register as soon as possible. You may be concerned about registering and then discovering that you can’t attend. This is understandable, so we are offering a no-questions-asked, complete refund until thirty days before the conference, August 14th. (At that point, we need to make certain financial commitments to our vendors, but if you need to cancel after that, we’ll apply your 2020 fee to provide a free registration for CppCon 2021.)
