Exciting Python features are on the way

Python 3.15 is bringing several notable features: lazy imports for faster startup without code rewrites, a new immutable frozendict type, improvements to the native JIT compiler, and a formal WebAssembly support plan via PEP 816. Additional highlights include progress on using Rust to build CPython standard library components, a new profiling explorer tool for Python's pstats format, a breakdown of the LiteLLM supply chain compromise, and a discussion on why open source pull requests go unreviewed for months.
