Version history


Version 1.4 - September 14, 2025

Sampling method, Sampling Steps, CFG scale and de-noising are no longer available as parameters in a project. These are replaced by Strategy, Energy, Guidance, Sharpen and Image drift.


I found the existing parameters too technology driven while our focus is on the users creativity. The change is more than a name change, under the hood there is a translation which is not straightforward but is different for each strategy.  The user can swap strategies, without adjusting other parameters and will see similar impacts on parameter changes throughout strategies. 


 10 is normal and the range goes from 1 (extreme low) to 20 (extreme high). No outrageous precision but 20 reasonable steps. 


The Strategies make use of sampling methods, not are sampling methods.


Other fixes and improvements:

  • The display of commands with a title "X Images Generated" took needless much screen space often causing a vertical scrollbar. The title is moved to somewhere more logical. Compacting space.
  • The pages Queue, Ready, History and Images have each a sort option and a filter.
  • When minimizing the application, the full screen preview minimzes too (if open)
  • Searching in "segments" and "recent" goes more natural.
  • In "Recent" is the number of remember lines doubled to 150.
  • Segments and Recent don't add unnecessary spaces anymore when a text is inserted.
  • When editing segments, you can use recent.
  • Scroll bars in Ready and History on commands with a lot of images were unhandy. They are now scrolling only the command, not the header, so that controls remain available.
  • When you did more than 11 Img2Img or Txt2Img from the same image or command then the yellow number showing the count displayed as 1 instead as e.g. 11. This is fixed, giving it more space. It can now go into millions and still display right.
  • All disabled buttons now look the same (instead of two different disabled styles)

Version 1.3 - June 24, 2025

It didn't work bad, ZTX37 running on top of Automatic 1111. We proved that our user interface was superior and this is how we want to work. You should not have all the power of a PC at your fingertips and then generate your images somewhere in some browser.


However...if we continue this journey, it is also time to stand on our own legs. Version 1.3 of ZTX37 doesn't need Automatic1111 anymore. Version 1.3 brings itself all it needs. Stable Diffusion XL is incorporated within ZTX37.


I fixed a few other things too:

  • Correct preview, also with non-standard image formats.
  • Scaling in IMG2IMG did not work, it just didn't scale. Now it does.
  • After startup, it took a few seconds before you could select a project. This is no longer so.
  • Some imported images, those with an alpha channel, resulted in very slow image generations. Fixed!
  • When trying to run two instances, the second one doesn't simply disappear, instead the first one is brought to focus.
  • There is a page containing a dialog for models now. This also provides a download button, helping you downloading models.

Version 1.2 - December 10, 2024

A new version! Quite a few improvements and enhancements, prioritized by the community.  Enjoy!

  • Revised Color Scheme: We've made the previously eccentric color scheme much more common and user-friendly. The community's feedback was clear—this change was crucial, and we're excited for you to see the new look!
  • Prompt Editor "Recent" Button: A new "Recent" button in the prompt editor provides access to a list of your last typed lines in chronological order. Click any line to insert it into your prompt, saving you time and keystrokes.
  • Spelling Correction: We fixed the spelling of "Ancestors," which was previously misspelled as "anchestors" throughout the application.
  • Command Limit Bug Fix: Resolved an issue where creating new projects became messy after 32,000 commands. Kudos to those who pushed the limits and helped us identify this!
  • "1 vs 1" Image Fix: Corrected a bug where "1 vs 1" did not open if there were initially fewer than 4 images. Now, it will only fail to open if there are fewer than 2 images.
  • Slideshow Enhancement: Slideshow now opens even if there is only one image. While it may not be the most useful feature in this scenario, it ensures consistency.
  • "Image Count" Window Accessibility: The "Image Count" window is now accessible from both the project and images tab, reducing the need to switch between tabs.
  • Metadata Removal: Images are now saved without metadata. Previously, SD added the prompt and all settings to each image. We now clear this information before saving, so images generated by ZTX37 contain zero metadata.
  • Import: You can now also import existing images. If these happen to have the above mentioned metadata, the prompt will be restored. Thus you can now move your old work into ZTX37 and continue expanding and improving it.

Version 1.1 - October 1, 2024

This is the first version of ZTX37 released publicly.  It is great enough to be an extreme useful tool for many, but we still have a lot of ideas.


Version 1.1 has:

* IMG2IMG

* TXT2IMG

* Segments

* Two image selection methods

* Continue work between sessions

* Storage of commands, linked to images.

* Various ways to browse your work.


Thanks to those who helped testing version 1.0. This helped a lot making 1.1 stable.


I am very curious what people think of it!
