Thanks for taking the time to do that list.
One trend to notice is that since subscription was introduced at the launch of 2019.0, more new features are introduced in dot releases, which in the past were mostly about bug fixes. Here’s an expansion of the 2019 and 2020 releases:
Many changes to the welcome screen, including adding subscription as an activation option.
Export for SketchUp options in LayOut DXF/DWG exporter.
Mouse scroll speed preference added to LayOut.
Dashed line layer style.
Tape measure help tip to check lengths and areas without needing to click or use Entity Info
Various OS compatibility improvements.
Change of auto save location to prevent the OS from deleting your files overnight.
Export line scale multiplier
Large area importing in Geo Location, for Pro or Studio subscribers.
Isometric dimensioning in LayOut. Auto text improvements.
Changes to cope with Google’s ending of the ability to sign in from within applications.
macOS Catalina support.
Object bounding box grips for Move tool.
Transparency of objects in order to position out of sight grips.
Ability to hide objects.
Layers changed to Tags
Control of the new SketchUp features from within LayOut.
Control of object visibility in scenes.
Section Plane and scenes improvements.
Editing of hidden objects.
Object grips added to Rotate tool.
Create empty object as a starting point for a new group or component.
Performance and select tool improvements in LayOut.
Voice controlled modeling. Just give a hint of what you want, and it will appear.
Ok, I may have made up the last two. Hopefully, seeing new features in dot releases will continue.
