C++26 shipped three big things: reflection, contracts, and std::execution. The first two get the headlines on this blog. std::execution (P2300) is the new standard model for asynchronous and parallel work, and it is the one most codebases will reach for first. Here is the smallest pipeline that does real work, running today on Compiler Explorer.
