Google announced Android 4.4 KitKat yesterday. You can read about the changes and improvements included in the new Android version here. Today they released a new version of the Android SDK and both ADB and Fastboot were updated.
Just a week ago Apple released iTunes 22.214.171.124 but as it is almost a given with them, they release a silent update right afterwards. This time the version is 126.96.36.199 which I assume only has very minor changes.
Skype has always provided an offline installer in MSI format for their Business version but it doesn’t support Facebook chat. There is a full offline installer of the regular version but it’s in EXE format. They should provide the MSI of the regular version but it’s easy to get once you install the regular one.
Apple has just released iTunes 188.8.131.52. The updated installers are already published on the downloads page. If you want to get the original files, go to Apple’s site.
