Action! 4.39.0 with new features and improvements is now available!

Hi Everyone!

W have just uploaded an update that includes changes from Action! 5.x:

• Major improvements for HDR capturing devices (Avermedia, Elgato/Corsair)
• Added automatic HDR signal detection and tone mapping for Avermedia and Elgato devices
• Fixed auto HDR detection for Steam games in Screen and Game capture modes
• Added color format selection for webcams and capturing devices (RGB, YUY2, NV12, P010 etc.)
• Added HUD in Device Capture mode
• Added browser overlay scaling (50-300% useful for displaying live chat on HUD in 4K)
• New advanced HDR to SDR tone mapper
• New improved SDR/RGB to HDR conversion for graphics/web browser/camera overlays in HDR mode

This release contains a critical fix for auto HDR detection which stopped working after one of the latest Steam platform updates.
