+- Major: Improve high-DPI support on Windows. (#4868, #5391, #5664, #5666)
 - Major: Added transparent overlay window (default keybind: <kbd>CTRL</kbd> + <kbd>ALT</kbd> + <kbd>N</kbd>). (#4746, #5643, #5659)
 - Minor: Removed the Ctrl+Shift+L hotkey for toggling the "live only" tab visibility state. (#5530)
 - Minor: Add support for Shared Chat messages. Shared chat messages can be filtered with the `flags.shared` filter variable, or with search using `is:shared`. Some messages like subscriptions are filtered on purpose to avoid confusion for the broadcaster. If you have both channels participating in Shared Chat open, only one of the message triggering your highlight will trigger. (#5606, #5625)
