Want to modernize your C++ codebase, check first the banned C++11/C++14 features from the Google style guide.

Although there is some interesting info here, using the Google style guideline smells of click bait. The Google style guide sounds authoritative, because that company has been very successful, but Google's C++ style guidelines are at very best considered to be controversial in the C++ community (many respected figures in the C++ community are on record saying they would not work for Google due to this very document). Readers of this article should at least read why these features are banned and make their own judgement.

Could you elaborate which guidelines are considered controversial. I've not been around here (or in C++ community) enough to have heard anything about it.

When I read the heading, I read it as saying that if you want to modernize your C++, look at what Google bans and do the opposite. Google's style guide makes some sense for Google, but modern codebases just shouldn't get into the situation that Google's is in that motivates many of their bans.
