example:

wppm -sa
mako 1.3.12 -> 1.4.2  GHSA-5639-2j2p-m4mx
nbconvert 7.17.1 -> 7.17.2  GHSA-pjvx-prjx-h659
# 550 packages checked, 2 advisories in 2 packages

wppm --register and wppm --unregister do work again, thanks to remark from @Jostikas

bug as human error by neglect, before Claude.

WinPython 2026-04 final (2026-10-27)

WinPython 2026-04 is the result of 2 month of works to prepare for Python-3.15.

Changes from WinPython 2026-03:

• Infrastructure:
  • SECURITY: python-3.15.2, python-3.14.10, python-3.13.8
  • SECURITY: pip-26.2.2, certifi-2026.10.23
  • SECURITY: wppm -sa / --audit gives users the everyday security bulletin on their current packages version
  • a just released version shall be wppm -sa alert-free
• Upgraded Packages:
  • polars-2.1.0, duckdb-2.0.0
  • numpy-2.5.3, numba-0.68.0, scikit-learn-1.9.1, scipy-1.18.1
  • jupyterlab-4.6.4, spyder-6.1.7, altair-6.3.0, matplotlib-3.11.2
  • all security alert fixed ... at the moment of build
• Removed Packages:
  • nltk: don't keep slow-on-security packages
• Differences among builds:
  • slimf (free-threading) are missing Qt
  • python-3.15 is only 90% complete: missing jupyterlab (because of pyyaml)
  • jupyter-ai only in 3.14 slim

Draft opened by the build workflow for cycle 2026_04. Files land as each build finishes; publish once they are all here.

Alternative requirements-with-hash256 and lockfiles, and how-to use with pip:
. with a requirement file:
. pip download --dest C:\your_temp_Wheelhouse --no-deps --require-hashes -r requir.64-3_14_7_0slimb3.txt
. pip install --no-deps --no-index --trusted-host=None --find-links=C:\your_temp_Wheelhouse --require-hashes -r requir.64-3_14_7_0slimb3.txt
. with a pylock file:
. pip install --no-deps --require-hashes -r pylock.64-3_14_7_0slimb3.toml --no-warn-script-location
