Apple released a new update to its OS X Yosemite operating system today. The update fixes an issue reported by some users that Yosemite causes Wi-Fi service to disconnect without warning. It also fixes an issue in the Safari browser that causes pages to load slowly.
The main points of the update are described in the screen grab from the App Store below.
Other fixes are more minor, including enhancements to Bluetooth and VoiceOver speech recognition performance, and stability improvements to Safari.
