* Enhance GPIO addon for Noctua Fans for the Qortector upcoming case. This will put PWM signal to real-time. * Fixed RDP not letting a user login if not logged out on Cinnamon release (reported by Crowetic) * Update i2c sensor db * Fixed DRM broadcast over HDMI 2+ * Ease up DHCP security only to prevent Brooklyn blocking routers. * Add possibility to add extra memory for Cinnamon Desktop Release * Fix error message of Software Render mode on Cinnamon Desktop * Add proper offset for HD screens for pixel array *Fixed HDMI jitter for videocore4 GPU * Enable all radios (including Bluetooth)
