To make it possible to select and configure audio devices this release is a start to make composable shared-state, composable preferences and composable widgets.

There are also a few other systems that have been updated:

• Co-routine; awaiting on a timeout.
• Simplified widget event handling.
• The color type can hold a RGBA color value or be a semantic enum value.
• Handle HDR on platforms with uniform HDR/SDR (windows 10 doesn't).
• Very fast 2 step index-array unicode character lookup.
• New grapheme type uses 21-bits and can be used as char of std::basic_string.
• New user-extensible char-encoding conversion system.
• std::format early static-type-check on hi_log*() macros.
• Add mode enumeration to widgets to handle visibility, disabled, enabled.
• Add a baseline system to align text between widgets on the same row.
• Improve observer<> to make sub-observers from member variables of the observed type.
• Audio device capability interrogation system.
• Reduce use of URL and use std::filesystem::path where appropriate.
• Rewritten file and file_view to function as copyable and movable value types.
• Split INSTALL documentation between different IDEs.
