Asus has released a new OTA update for their Transformer TF300T tablet. The update brings the device to version 10.4.2.13 and Android version 4.1.1. The TF300T already has Jelly Bean so the update doesn't bring any major changes, but this build of Android 4.1.1 is supposed to bring increased stability, camera tweaks, and bug fixes. Some users have reported issues with updating rooted tablets, so if you are rooted, it's recommended that you unfreeze all system apps and backup root before applying the update. You can grab the update by going to menu> settings>about device>software update. The update should be available to everyone within the next day or two, so if it doesn't show up immediately check back later. If you get it, let us know what you think in the forums.
