The Core Dispatch covers July 5-18, 2026, highlighting Python 3.15.0 beta 4's release. This beta version arrived on July 18, with subsequent releases including Python 3.13.15 and 3.14.7 planned for August 4. The core team is currently at EuroPython, where their annual Language Summit also took place; recordings will be shared later. Discussions on new Python Enhancement Proposals (PEPs) are ongoing and active. Notable PEPs include PEP 835 for annotated metadata shorthand and PEP 836 concerning JIT compilers. New PEPs like PEP 840, dealing with class namespace name resolution, have also been introduced. Users are encouraged to test the final 3.15 beta and report any issues. Several PEPs are highlighted for updates, including Shared Object Proxies and adding python-version to pyvenv.cfg. Merged pull requests introduced new functionalities to modules like ipaddress and tkinter, alongside improvements to tarfile and email utilities. Core development discussions include securely publishing to PyPI and fixing dictionary behavior in Python 3.14. Upcoming conferences and calls for papers are also listed, with deadlines approaching for several events.
