• fix: installer makes sure that no files from former Vision4D versions are left in the installation folder
• additional small fixes and improvements in the arivis_dl library

New & Noteworthy: 

• New optional module: arivis AI toolkit features a complete Deep Learning workflow right in Vision4D - annotate, train & inference 
• Various improvements in the tracing workflow 
• Wellplate Editor to manually assign imagesets to wells or fields of a well 

arivis AI Toolkit: 

• new: Optional module arivis AI toolkit: 
• new: Deep Learning Trainer panel to setup and train a DL model
• new: use the Draw Tool to draw segments to annotate regions for classes 
• new: utilizing of sparse annotations to overcome the need to draw on every pixel 
• new: drawn objects are sorted by class order - pixels are assigned to the topmost one (no need to cut out overlaps) 
• new: add and reuse existing segments for class definition 
• new: automatic clustering based on annotated backgound possible 
• new: run and monitor the DL training process right from Vision4D 
• new: directly open the trained DL model in the Analysis Pipeline for inference 
• new: export the trained DL model as ONNX 
• new: additional installer package to setup a whole DL Python environment 

Tools: 

• new: Draw Tool has a context menu and better keyboard shortcut support 
• new: Draw Tool is aware of the DL Training panel 
• new: Draw Tool allows to change class to draw by shortcut or context menu (in DL Trainer mode) 
• improved: Trace Tool - connect to a cell body segment 
• improved: Trace Tool - optimized remove branch 
• improved: 'unable to connect' messages in the Trace Tool are more understandable 

Analysis: 

• new: 'Neuron Tracer' (from the Segmentation category) has been renamed to 'Neurite Tracer' 
• new: 'Neuron Tracer (from Cell Body)' has been renamed to 'Neuron Tracer' 
• new: Neuron Tracer preview shows all parts in the same color 
• new: Neuron Tracer preview shows the filtered parts slighly dimmed (instead of hiding them completely) 
• improved: parameter labels in the Neuron Tracer are more precise 
• improved: default threshold value and threshold warnings in the Neuron Tracer 
• improved: tooltips in the Neuron Tracer 
• fix: if the tracking operation had a lot of results, it could happen that the last tracks were not displayed 
• fix: prevent the creation of (almost) empty traces in the Neuron Tracer 
• fix: ensure that a preview progress label is always displayed immediately 

Visualization: 

• new: display of starting points can be turned off for traces 
• improved: optimized cone generation for traces in 4D Viewer 
• improved: fallback to line based visualization if cones for traces would exceed memory 
• improved: remember last used Z-Projection value for trace visualization in 2D 
• fix: minor problem with RGB Projection in 4D Viewer 
• Data Handling: 
• new: Wellplate Editor to manually assign imagesets to wells or fields of a well 
• new: semi-automatic assign imagesets to well or field positions based on the name of the imageset (in the Wellplate Editor) 
• new: additional import scenario to import wells as imagesets and open the Wellplate Editor afterwards (for manual assignemnt) 
• fix: some LaVision data could not be imported correctly for TileSorter 
• fix: problems with some CZI if imported for TileSorter 

General:
