# Small Safety Improvements in the C++ 26 Core Language – MC++ BLOG

**[MC\+\+ Blog](https://daily.dev/sources/modernescpp)** · 6 min read · 2 upvotes · 0 comments

## Summary

C++26 introduces three key safety improvements to address common programming pitfalls: preventing binding returned references to temporaries, converting uninitialized reads from undefined behavior to erroneous behavior with automatic initialization, and making deletion of pointers to incomplete types ill-formed unless they have trivial destructors. These changes help catch dangerous patterns at compile time and provide safer defaults for memory management.
