Django News Newsletter issue 343 covers the release of Django 6.1 beta 1, available for community testing ahead of the August 5 final release. Key Django updates include a deprecation for calling QuerySet.aiterator() after prefetch_related() without chunk_size, and EmailMessage.message() now raising ValueError for Bcc in headers. Python 3.15.0 beta 3 is also out with lazy imports, frozendict, a faster JIT, and UTF-8 as default encoding. Other highlights include the Django Software Foundation becoming a CVE Numbering Authority, Djangonaut Space mentorship results (104 contributors from 40+ countries), Wagtail as a Django admin replacement, a custom Django/Python linter (boa-restrictor), PEP 832 for virtual environment discovery, and a python.org authentication bypass disclosure and mitigation.
