New

• Razer Synapse Standby: park and resume Synapse, keep Chroma lighting running, optional boot guard
• Max Fan one-click button
• Battery charge limit 50-80% in 5% steps
• AC / battery launch profile
• Custom logo and banner support, new icon, device model in the footer

Fixed

• UI lag while Razer Chroma / Synapse are running
• Stale CPU/GPU boost values after launch
• Performance mode highlight not following the device after an AC/battery switch

Known behavior

After the battery limit is reached, the firmware only resumes charging once the battery is about 10 points below the limit. To restart charging, set a limit at least 10 points higher (80% works), then lower it. See the README for details.

Full details in CHANGELOG.md. Only the Blade 16 (2023) has been tested; reports from other models are welcome.
