6.22.3 (2026-09-12)

Bugfix

* (Windows) Revise earlier fix for :issue:`9508` to avoid breaking
  executables located on ImDisk RAMDISK volumes. (:issue:`9510`)
* Compare the icon file suffix case-insensitively, so an icon named with an
  upper-case suffix such as ``MyApp.ICO`` is recognised as already being in the
  right format instead of being rejected or silently re-encoded.
  (:issue:`9521`)
* Fix ``onefile`` parent-process validation to allow intermixed nested
  sub-processes. (:issue:`9513`)
Bootloader

• (POSIX) Enable onefile parent-process validation for POSIX executables that have setgid bit set, and for Linux executables that have file capabilities set (i.e., have a security.capability extended file attribute). (:issue:9524)
• (POSIX) Revise the validation of owner and permissions of onedir application's contents directory when the executable has either setuid or setgid bit set. If setuid bit is set, the owner ID of the application's contents directory must match the owner ID of the executable itself, and only owner is allowed to have write permissions on the directory. If setgid bit is set, the group ID of the application's contents directory must match the group ID of the executable itself, and only owner and the group are allowed to have write permissions on the directory. (:issue:9524)
• Limit onefile parent-process validation only to executables that are running with elevated privileges while inheriting environment variables set by unprivileged user. On POSIX systems, this corresponds to executables with setuid bit set, while on Windows, it corresponds to UAC-elevated processes (running with TokenElevationTypeFull token). (:issue:9520)
