+## 6.1.1

+* Release Windows apps no longer ship Python's debug modules (`*_d.pyd`), about 10 MB each ([#260](https://github.com/flet-dev/serious-python/pull/260)).
+
 ## 6.1.0
 
 * **The bundled CPython runtimes move to 3.12.16 / 3.13.18 / 3.14.10** (from 3.12.15 / 3.13.16 / 3.14.8), from python-build **20261027**. These are expedited security releases: they stop trusting the compromised eMudhra intermediate CA keys ([CVE-2026-115557](https://github.com/python/cpython/issues/160040)) and reject links that replace the extraction destination in `tarfile`'s `tar_filter` ([CVE-2026-114583](https://github.com/python/cpython/issues/160097)), among other fixes. Pyodide and `dart_bridge` versions are unchanged ([python-build#48](https://github.com/flet-dev/python-build/pull/48)).

+* **Release Windows apps no longer ship Python's debug modules.** The 3.0.0 rewrite of the `DLLs` copy step lost the removal of `*_d.*` from Release builds, so every app carried each extension module twice (`_ctypes.pyd` and `_ctypes_d.pyd`, …): about 10 MB and two dozen files more than needed, and as many extra signatures when the app is code-signed. Release and Profile builds now drop them again; Debug builds keep them ([#260](https://github.com/flet-dev/serious-python/pull/260)).
