Alpha v0.19.1

This update has a critical fix for the image file iterator as well as many MacOS improvements.

Changes

• System usage meters now use traffic-light color scheme (#2023, thanks @stonerl)
• MacOS clipboard improvements (#2031, thanks @stonerl)
• Help menu improvements (#2041, thanks @stonerl)

Alpha v0.19.0

Hey everyone. It's been a while since the last update, and in my opinion, it's been worth the wait. We have a lot of interesting improvements and new features to share with all of you.

First, we now have documentation for all available nodes. This can be accessed both by a button in the top right button bar, as well as by right-clicking on a node in the sidebar and clicking "Open Documentation". The documentation includes a lot of information about nodes and their inputs & outputs. Not to mention, the docs are also searchable. This will hopefully be a huge help to both new and existing users.

Second, the update screen has finally received a makeover. This has been a long-overdue change. Starting with 0.19.0, you will get a popup when there is a new update, which will have an option for ignoring the update or viewing the update's changelog. If you view the changelog, a modal will open that will show you a full changelog of the update -- or multiple updates if you happen to be a few versions behind. From there you can view the release on GitHub or open chaiNNer.app to download it. If you do choose to ignore the update, don't worry, because you will see a green download indicator next to chaiNNer's version number which you can click on to view the update again.

Third, we've made some improvements to how the backend sets up chaiNNer. This is mostly to prep for future features, but it also conveniently makes it slightly easier to set up chaiNNer on a remote machine, as all the necessary dependencies will be installed via the backend, instead of the frontend. This shouldn't affect existing users much, except you may notice that on starting up chaiNNer this time you see a slightly different progress indication on the splash screen as it installs the few new necessary dependencies. We also now bundle a couple of small, cross-platform dependencies that should make first-time setup a bit faster. If anyone is having trouble with the new first-time setup process, definitely let us know ASAP.

Fourth, chaiNNer is now taking advantage of some first-party Rust code. This means we were able to speed up certain nodes by a significant amount. Expect future updates to improve the speed of other nodes as we move some intensive operations over to Rust.

And now for the changelog:

I know I just did a release, but I couldn't wait to get this out. I finally fixed the broken windows installer :)

Bug Fixes

• Fixed the windows installer not opening after install/update (#1830)
• Fixed being unable to pass in electron-specific launch arguments to chaiNNer (#1830)
• (unconfirmed) Fixed MacOS and Linux portable builds to be truly portable (#1829)

Alpha v0.18.8

Note: this is another reminder that the windows installer doesn't open after installing. It's a known bug we haven't been able to fix

Another small update with some bug fixes and a couple of new features.

Changes

• Add FFv1 support to Video Frame Iterator (#1779)
• (onnx) Add FP16 option for tensorrt (#1795)
• (pytorch) OmniSR Support (#1804, #1813, #1815)

New Nodes

• Pixelate (#1777, thanks @harisreedhar)
  • Pixelate an image, similar to Photoshop's "Mosaic" filter

Bug Fixes

• Fixed bug with generating hashes after an upscale (#1797, thanks @Zarxrax)
• Fixed a bug that would show invalid nodes in the right-click node-selector context menu (#1821)

Also, thanks to the following maintainers: @joeyballentine @RunDevelopment

Alpha v0.18.7

This is a small update with some new features and bug fixes.

Changes

• Small performance optimizations (#1743)
• Colors are now a data type and are selectable via color picker in many nodes (#1732)
• Added missing previewing features on Text Areas (#1766)

New Nodes

• Generate Hash (thanks @Zarxrax) (#1738)

• Fixed Fill Alpha causing errors in certain chains (#1768)
• Fixed iterators not properly catching certain types of errors (#1771)

Also thanks to the maintainers who contributed to this release: @joeyballentine @RunDevelopment

Alpha v0.18.6

This is a slightly bigger update that didn't quite qualify for a major version number. It includes lots of bug fixes and a few new highly-requested features.

Changes

• Changed some node ordering and group names (#1679)
• Add weight support to CodeFormer when using Face Upscale (#1714)
• Add ETA to iterators (#1730)
• Optimizations (#1710, #1717)
• Rename Spritesheet Iterator's dimension inputs (#1716)
• Only show the "Separate Alpha" option for RGBA images (#1721)
• Better generated error reports (#1724)
• Removed the "disable hardware acceleration" option, and always disable hardware acceleration (#1722). A user noticed that having it off significantly improved upscaling times, so we figure there is no reason to use it (all of us devs have had it off). If you need an override because disabled hw acceleration is causing issues, please let us know.

Bug Fixes

• Fixed a bug with Combine RGB if no alpha channel was given (#1715)
• Fixed some bugs with output normalization (#1717)
• Fix ESRGAN-2c2 scale detection for lower scales (#1712, #1729)

Bug Fixes

• Fix ONNX RemBG node error (#1706)

• Fix "dynamic scale" (they aren't really dynamic scale, but they act like it) realesrgan NCNN models (#1698)
• Fixed image dimensions in error messages (#1701)

Thanks to the contributing maintainers: @RunDevelopment and @theflyingzamboni

Bug Fixes

• Fixed issue causing Stable Diffusion nodes to not work (#1623, thanks @adodge)

Alpha v0.18.2

NOTE: This is another reminder that the installer still has an issue that makes chaiNNer not open automatically after install. It does still install, so just open it manually after.

This update addresses a few bugs, but mostly adds a few cool nodes.

Minor Changes

• Consistent UI font between platforms + switch to using Open Sans (#1610, #1614)
• Seeds are now their own datatype rather than numbers (#1611)
