Over the weekend, Palm pushed out a new update of its WebOS operating system to Palm Pre users (if you have not seen it, hit that update icon on the last page of the launcher screen).  There are a lot of small enhancements in this one, the most prevalent of which is that Yahoo email and contacts.  You can see the full list of updates on Palm’s website.   But there is plenty more, which you may not already have seen.  The folks over at Precentral.net have compiled a list of undocumented features in WebOS 1.3.1, including:

• speed enhanced web browser
• changes to the Linux kernel which lay the groundwork for a potential video camera in the future
• snappier photo interface

So, Pre users, you can download the new WebOS directly from your phone, and start enjoying the new features in about 10 minutes.  And if you notice any additional features, leave a comment and let us know what you found.
