SMRTR summary

Python 3.14 introduces several major new features and improvements:

Template strings (t-strings) provide a generalization of f-strings for custom string handling. Multiple interpreters are now supported in the standard library, enabling new concurrency models. Annotations are now evaluated lazily by default, improving performance. A new Zstandard compression module is added to the standard library. The debugger interface allows safely attaching to running processes.

These enhancements aim to boost performance, expand concurrency options, and provide more powerful string handling and compression tools.
