Arctis Sound Manager has been released in version 1.4.30, shortly after version 1.4.29.

The mixer has been completely redesigned: sliders and the ChatMix bar now use fader caps, and toggles, dropdowns, checkboxes and button groups consistently follow the theme colors. Applications are also shown as centred icons under each channel slider instead of their names, and a new built-in theme called Matcha SV has been added. Among other fixes, native Linux Steam games are now correctly routed to the Game channel.

Added

• Applications are shown as icons under each channel slider, centred and wrapping, instead of their names.
• A redesigned, fully themed mixer. Sliders and the ChatMix bar use fader caps; toggles, dropdowns, checkboxes and button groups follow the theme colors.
• New built-in theme: Matcha SV
• EQ preset and output device pickers now open searchable lists with grouped device settings panels

Fixed

• Native Linux Steam games were incorrectly routed to Media instead of Game channel; now all Steam games default to Game (#265)
• Crash reports from previous versions were reappearing under new version numbers; reports now include version tags and older reports are filtered out (#284, #285)
