Aug 17 at 4:29 comment added gnasher729 Quite common is new features using new keywords that cannot be used as plain identifiers anymore. For example, at some point “int restrict = 0;” became invalid C.

Fixed spelling, improved flow
Jan 20, 2023 at 14:00 comment added pjc50 There was a certain amount of breakage before standardisation, but that was way back in the 90s. It's like asking about pre-ANSI C.
Jan 20, 2023 at 13:57 comment added pjc50 Closed now, but the C++ breakages have tended to be in obscure corners and not to affect most codebases, while the print change affected almost every single script, and (more importantly) the unicode change broke almost every single piece of text handling. Also, you can often use older C++ libraries in updated programs, while the same was not true of python and crippled the upgrade.

Jan 20, 2023 at 10:00 comment added Doc Brown Questions asking for long lits of things are not well suited for this site. But you can lookup the breaking changes at the official standards, as Caleth pointed out. Unfortunately, asking for 3rd party resources is off-topic for the site. If you ask me for a change similar to the change from Python2 to Python3, I think Stroustrup intentionally chose to make C++ not 100% backwards compatible to C, for the purpose of creating a more powerful language.

Added focus to the question, to strictly be about instances which broke backwards compatibility
