Seems that LiteOn has been busy releasing various firmware updates for some of their products:
* Lite-On 24/10/40 (retail), version 5S0J
download
* Lite-On 16/10/40 (oem and retail), version OS0F
download
* LiteOn LTN-486, version 0U0F
download
So if you own one of these drives, go ahead and download.
For the ones who are concerned about changelogs... I wish I could tell you what changed, but since nothing has been reported by LiteOn, I really don't know!
