-# STAGE 3 of the decoupled release pipeline: PROMOTE a built + notarized version
-# to "live". By this point:
-#   - stage 1 (Release Desktop) built the installers, mirrored them to R2, and
-#     registered them in D1 as unpublished (is_latest=0);
-#   - stage 2 (local desktop/build/notarize-dmg.sh) notarized + stapled the mac
-#     dmgs and re-uploaded the stapled bytes to R2.
-#
-# This workflow, triggered manually with the version to publish:
-#   1. pulls every artifact for that version back from R2,
-#   2. recomputes sha512 from the real (stapled) bytes and updates D1,
-#   3. flips is_latest=1 for that version (clearing the previous latest per
-#      platform) UNLESS it's a pre-release, which is recorded but never latest,
-#   4. creates/updates the GitHub Release and attaches the installers.
-#
-# Run only after the mac dmgs for this version are notarized + re-uploaded.

+# One-off / on-demand build for legacy Windows 7 / 8 / 8.1 users.
+#
+# The main release pipeline (release.yml) ships Electron 33 (Chromium 130+) and
+# a PyInstaller backend built with Python 3.11 — NEITHER runs on Windows 7,
+# which is why those users hit "不是有效的 Win32 应用程序" when launching the exe.
+#
+# To support Win7 we must pin BOTH halves to the last versions that still
+# target it:
+#   - Electron 22.3.27  (Chromium 108, last major to support Win7/8/8.1)
+#   - Python  3.8        (last CPython to support Win7)
+#
+# This is a SEPARATE, manually-triggered workflow so it never touches the
+# production R2/D1 publish flow or the auto-update feed. It just produces an
+# unsigned NSIS installer and uploads it as a build artifact for manual
+# download + testing. Delete this file whenever Win7 support is no longer worth
+# maintaining — the main pipeline is completely unaffected.
+#
+# IMPORTANT for end users: Win7 must have SP1 + update KB2533623 (or the rollup
+# KB4457144) installed, otherwise the Python 3.8 backend still fails to start.
