Python Releases 3.15 Beta 1 With Low-Impact Profiling and Faster JIT

Python 3.15 beta 1 is now available, giving developers an early look at the release’s headline additions, including low-to-no-impact profiling tools.
New features highlighted in the beta include lazy imports, faster JIT compilation, better error messages and a statistical sampling profiler designed to inspect programs without noticeably slowing them down.
Python 3.15 also builds on low-level hooks introduced in Python 3.12+, which third-party tools such as tprof use to collect runtime statistics without requiring code instrumentation.
The beta arrives as Python tooling broadens beyond the core language, with Mojo 1.0 repositioning itself from a would-be Python replacement toward a Python-Rust hybrid focused on speed and memory safety.
