Apple on Tuesday released an update to OS X Lion to version 10.7.1 – the update is available through the Software Update system preference, and is recommended for all Lion users.

Apple says the update includes “general operating system fixes that enhance the stability and compatibility” of your Mac running Lion, but calls out a few changes specifically, including fixes that:

• Address an issue that may cause the system to become unresponsive when playing a video in Safari;
• Resolve an issue that may cause system audio to stop working when using HDMI or optical audio out;
• Improve the reliability of Wi-Fi connections;
• Resolve an issue that prevents transfer of your data, settings, and compatible applications to a new Mac running OS X Lion.
