Lots of fantastic changes coming in 4.5, some of which are a long time coming.

My personal highlights:

• Proper SVG support and text scaling
• Tilemap chunking which boosts performance and stops glitching in-between tile seams
• Variadic arguments in functions
• In-editor translation previews
• Windows exports no longer need rcedit to change the icon/metadata!
• Build profile now properly detects everything in your game, giving you a file to exclude all the nodes and features not used to easily reduce binary size
• Emission shape gizmos on 2D particles (finally)
• Screenreader support
• Recursive focus modes and mouse passthrough for Control nodes
• Borderless fullscreen mode on Windows finally doesn’t have a 1px outline
• Deep duplicates of resources finally work, previously anything in collections like arrays wouldn’t get duped and you had to go through them manually
• Lots of optimizations for the web
