We submitted a pull request to remove Basilisk from the Python typing repo. Many of the conformance tests were depending on pattern matching text in the PEP tests. We're working on fixing this and we will update the website ASAP. Read about it here github.com/python/typing/pul…

⚡ Cold `basilisk check` got cheaper: a precomputed `builtins.pyi` index, lazy off-thread typeshed activation, zero-copy stub decode — and no Python spawn for auto-discovered interpreters, whose `sys.platform` and `site-packages` are already knowable. (#375)

🐛 `str.join` arguments are now judged by their resolved TYPE instead of the syntactic shape of the expression. That one change closed 4 false positives and caught 1 error we were missing. (#357) 🧵

📥 New rule: `imports_missing_name` flags `from M import X` when workspace module M defines no X. Deliberately conservative: a module-level `__getattr__`, a star-import, or an unreadable target all keep it quiet. (#362) 🧵
