New Features:

Nothing known

Enhancements:

• USB mute sync stability has been improved.

Fixed Bugs:

• Several bug fixes have been implemented.

Open Issues:

• Shure Audio Encryption is not backwards compatible; all devices must be on firmware version 4.1+ to use this feature.
• The P300 Shure Audio Encryption may sometimes exhibit a brief crackling sound on audio after muting.
• The Shure Update Utility and Designer may not allow downgrading of new P300s shipped with 4.2.7 or higher due to platform updates.
• P300s with firmware 4.3 require Designer versions 4.3 and higher; they will NOT be supported in Designer versions 4.2.1 and earlier.
• P300 firmware periodically adds new properties, which could make the device undiscoverable if downgraded, necessitating a factory reset to become discoverable.
• If attempting to load the device's web page after using SUU to upgrade or downgrade between MXA 4.3 and earlier releases, the browser may appear stuck on the "Loading" screen.
• Workaround: Hold your Shift key and click the Refresh button in your browser (or press Ctrl+Shift+R \[Win\]/Ctrl+F5 \[Win\]/Cmd+Shift+R \[Mac\]; note the keyboard shortcut doesn't work on Safari).
