Moderator's note: This thread is just for new features found. Discussion posts are now here.
Here we go(stole the original list to start):

- App Catalog updated to support purchasing apps
- Web browser enhanced
- auto zooms to forms
- download in browser enabled (including opening pdfs)

- Select All option in Edit menu
- Save images in browser(Not GIF, assuming JPG and PNG only, Orange+click to do this)
- Clock app allows you to turn off alarms when mute switch is on
- The full Facebook page now saves your login info, and is much easier to use because of auto zooming to text boxes
- Speed increases across the board, notifications are much snappier
- Dialer is snappy, minimal to no lag on anything
- Selecting text and scrolling through text boxes is smoother, more accurate, and selects full words now
- Can now disable Data(EVDO) and use WiFi in conjunction with standard voice service(Major battery saver, though there is an issue with it, you cannot make WiFi stay active when the screen is off and the phone isn't plugged in)
- Can now copy entire conversations in Messager
- Displays phone number when using the phone, instead of just Mobile or Home etc
- If you are on the main screen or launcher.. in you press gesture+v to paste, it will start a global search with whatever you pasted.
- Tasks now gives the option to sort in "My Order" (how things were entered), by due date, or priority.
- Email search, though it only searches subject and sender right now
- No more having to manually link AIM contacts to people if you already have that AIM name in the Google profile
- The default Pre Ringtone has changed
- Text Notifications now include a contact picture
- Pinch to expand emails has been removed.
- Updated mojo framework (200.18) on 1.1 it was 191.15(Probably responsible for the performance increases across the board)
- Sprint Configuration is now v1.8
- There is a "Send all to Car Kit" option in the Contacts Application now
- Calendar now has additional preference setting for "Calendar View Options" to set the color of your calendars and to show them in the "All Calendars" view.
- WAV's now play directly from email(though I can't figure out how to save them)
- Sound alerts while on a call no longer deafen you
- When you get an incoming call the number now shows up at the top of the locked screen instead of the bottom (so it's not hidden by the "slide up to answer" button anymore.)
- Memopad is now back to single click to move the cursor
[*]Bookmarks are now backed up by the Palm Profile

On the WebOS Quick Installer, I've tested the mods to see which work, and I can tell you which ones not to try:
Don't do anything to the Messager
Don't do anything to the Email client
I'm also assuming don't do anything to the PDF Viewer
4x4 icons works, Hiding Nascar and NFL work, Call Duration in Call Log works, changing logos/backgrounds still work, Silencing the dial tones still works, and Add/delete launcher pages works. Thats the stuff I tested(besides PDF Viewer).

Feel free to add anything I might have missed, and I'll update the OP.
*Disclaimer: I do not suggest installing this, unless you are familiar with rooting your phone and can disable the UpdateDaemon. This update is, as far as I'm concerned, experimental, beta, and definitely not supported by Palm, since it isn't official. My suggestion is to wait for the official release. This update has a build date of 8/30, so its already a few days old, I'm guessing the final release will have a different build date, and hopefully incorporate some of the changes mentioned in the other thread.
