Zerene Stacker Beta Testing Downloads

Looking for an explanation of how our “beta channel” works? See HERE for an explanation.

Note: Because these beta versions are downloaded relatively few times, they are sometimes not recognized as known good software by anti-malware packages. You may have to override your anti-malware's behavior of refusing to run unrecognized software.

If you have other security concerns about the beta installers, please see How To Validate A Download.

Current beta is:

  • 64-bit Windows 11, 10: ZS-Win64-fullsetup-T2026-05-04-0750-beta.exe
    This installer is for most Windows computers, which still run Intel and AMD processors (actually anything Intel-compatible). It will also run on Windows 11 ARM computers in emulation mode.
    Length 34854520 bytes
    MD5 checksum 925b1e23a66b5f36fecb92eca6b80b26
    SHA-1 checksum e27850023aff71f5b132d35f58761cd113355bd1
  • macOS universal: ZS-macOS-universal-SA-T2026-05-04-0750-beta.zip, downloads as a .zip file that automatically expands into an application bundle named ZereneStacker (.app).
    This is the recommended bundle for all modern Macs. It supports both “Apple silicon” M-series cpu (ARM architecture) and Intel cpu. It is self-contained and includes its own Java 25 runtime environments. Rosetta is no longer required for this build.
    Length 91,304,391 bytes
    MD5 checksum 2d704611b55ef326c8e79ae6dc84f330
    SHA-1 checksum 1c970b1deae666acff3db66e50b4b1a01baf3bda
  • 64-bit ARM Windows 11: ZS-WinARM64-fullsetup-T2026-05-04-0750-beta.exe
    This installer is specific for Windows 11 computers with ARM processors, such as Qualcomm Snapdragon. It runs in ARM-native mode and will not run on Intel and AMD processors. With ARM processors, this version is significantly faster than running the Intel version in emulation mode.
    Length 33484312 bytes
    MD5 checksum f3a6814b4eb37f666173e356a6bb09e4
    SHA-1 checksum 5749b0efde34d146ff7b1b44eadcba318917b9ac

Note 1: This and all future versions of Zerene Stacker will require a 64-bit processor and relatively modern operating system. Support has been dropped for 32-bit processors. Support has also been dropped for Windows XP, 7, and 8, and for MacOS 12 and below.

Note 2: On Macintosh and Linux, if you already have Zerene Stacker installed and are downloading a new version to update it, then you need to manually move the old version to trash, and move or rename the new version to replace it. Otherwise both versions will continue to be available, and you will run whichever one you happen to click on. For further information, see the FAQS on “Installing and Updating”. On Mac, when trashing out the old version, do NOT allow any third party uninstaller or cleanup applications like “AppCleaner” to run. In their enthusiasm to eliminate files that they think are not used, they're likely to also delete files you really do need, like your license key and Zerene Stacker configuration files.

Improvements

Compared to the previous production version T2026-02-27-1525 and its corresponding T2026-02-27-1525-beta, this new T2026-05-04-0750-beta incorporates the following improvements:

  • Mac packaging:
    • The distribution is now “universal” (Apple Silicon + Intel cpu), to conform with future Apple requirements and avoid current warning messages.
  • User interface:
    • Initial size for retouching brush is increased to 100 pixels.
    • If source file is not found, open search navigator in parent folder of project.
    • Added “Copy All” in context menu for text fields such as console log window.
    • jdk.accessibility is now supported (including Java Access Bridge on Windows).
  • Launch configuration:
    • Added -showjavaconsole debug option for Windows launch programs.
    • Display system accelerations are now disabled by default on all platforms, for improved resistance to computer quirks.
    • Added Options > Preferences > Look & Feel > “Use operating system display accelerations” to override the new default.
    • Added zerenstk.cfg tag “LaunchConfiguration.JVM.PersistentArgs” to allow custom configurations without altering installation files.
  • Bug fixes:
    • Image orientation specified by EXIF tag was not honored.
    • EXIFPropagator would occasionally fail with special characters in Windows username.


Please immediately inform support@zerenesystems.com if you encounter any difficulties or odd behavior with this beta version. Be sure to send a console log if appropriate – instructions for that are provided HERE.

Previous public beta was:

  • macOS (M-series cpu): ZS-macOS-AppleSilicon-SA-T2026-02-27-1525-beta.zip, downloads as a .zip file that automatically expands into an application bundle named ZereneStacker (.app).
    This is the recommended bundle for modern Macs with an “Apple silicon” M-series cpu (ARM architecture). It is self-contained and includes its own ARM-native Java 25 runtime environment. Rosetta is required for the launch program and a few helper programs – so macOS will report the package as “Intel” – but all the heavy computation runs ARM-native.

  • macOS (Intel cpu): ZS-macOS-Intel-SA-T2026-02-27-1525-beta.zip, downloads as a .zip file that automatically expands into an application bundle named ZereneStacker (.app).
    This is the recommended bundle for modern Intel Macs running macOS 13 or above. It is self-contained and includes its own Java 25 runtime environment.
