v5.9.0

This release adds FLUX Fill support in Workflows and Canvas, beta support for the LLaVA OneVision VLLM family of models, and a selection of minor fixes and enhancements.

## FLUX Fill

FLUX Fill provides high quality inpainting and outpainting, improving on these tasks over the other FLUX models. It's a "main" model, like FLUX dev or schnell.

To use it, download it from Starter Models and then select it from the main model drop-down on Canvas. It's not compatible* with Text to Image or Image to Image - you'll get an error if you try to Invoke without an inpaint mask or some empty regions in your bbox.

> *Technically, it _can_ do Text to Image and Image to Image - but the quality is very poor. We've opted to disallow this on Canvas.

## LLaVA OneVision VLLM

This multimodal model generates text from text, image and/or video* inputs. You can use it to generate prompts and and describe images. You can use it in Workflows with the `LLaVA OneVision VLLM` node.

The 0.5B variant of the model is available for download from Starter Models.

> *Invoke does not support video inputs.

## Other Changes

- Support for custom string field drop-downs in Workflow Builder. Add a node's string field to the Builder and choose the dropdown component to see it in action.
- The About modal now shows the app's runtime settings. It includes a list of explicitly-set settings (i.e. the contents of `invokeai.yaml`), so it is possible to see what runtime settings are app defaults and which are user-defined.
- Improved UX for missing or unexpected fields in Workflows.
- De-wonkified LoRA node names (they got wonkified in v5.8.0).
- Better error messages when scanning models with `picklescan`.
- Fixed issue where shift-clicking to draw on Canvas ignored `Clip to Bbox` setting.
- Fixed issue with Image Viewer where the image could overflow the viewer.
- Fixed overflow with looooong node titles.
- Fixed a minor visual bug in string generator nodes.
- Internal: First iteration of improved model probing API.
- Internal: Improved testing system for model-related tests.
- Internal: Port LLaVA OV models to use new API.
- Internal: Cleaned up a lot of model-related code.
- Internal: Support hot reload for custom nodes. Thanks @keturn!
- Updated translations. Thanks @rikublock @Harvester62 @Linos1391!

## Installing and Updating
**The new Invoke Launcher is the recommended way to install, update and run Invoke**. It takes care of a lot of details for you - like installing the right version of python - and runs Invoke as a desktop application.

Follow the [Quick Start guide](https://invoke-ai.github.io/InvokeAI/installation/quick_start/) to get started with the launcher.

If you don't want to use the launcher, or need a headless install, you can follow the [manual install guide](https://invoke-ai.github.io/InvokeAI/installation/manual/).
