- H.264 WebRTC: Refactored to significantly reduce video latency - H.264 Direct: Optimized data transmission; data parsing now continues correctly even when the tab is in the background - MJPEG: Refactored to ensure the correct data length is sent Bug Fixes - Fixed an issue where certain keyboard modifier keys were not recognized - Fixed vertical mouse cursor drift when the page is zoomed in or out Optimizations - Optimized HID write logic and updated the HID reset mechanism - Added support for deleting images - Added a Swap Memory option to the Tailscale page - Added a confirmation dialog when uninstalling Tailscale to prevent accidental removal - Improved the logic for updating the web page title - Improved the UI for the Clipboard, Settings, Image Mounting, and App Update pages Security - Added a mandatory delay after failed login attempts to prevent brute-force attacks - Updated dependencies to patch known security vulnerabilities
