Last night, Verizon updated their Droid 2 support page to announce a new update (v4.5.621) is coming soon rolling out now. While it doesn't bring anything major (*cough* Android updates *cough*), it does bring a few significant bug fixes and improvements:

Or, in non-image form:

Device Features
+ Device is enabled with the Wireless Alerting System.
+ A Google Security Patch has been added to improve security level.
+ Fixed issue where the device may power ON without user interaction.
+ Adjusted camera settings will be saved, even after the device is powered down.
+ Resolved possible device resets while playing music.
+ Reduced Out of Memory errors.

Email, Messaging & Data
+  Improved ability to access and receive Gmail messages when the
    Mobile Hotspot is turned on.
+ Addressed error that replicated thumbnails in message threads.

Applications & Widgets
+ WAV files can be played from Visual Voice Mail.
+ Purchased ringtones are now able to be downloaded, saved and used
where appropriate.

The update process is the same as always - head to Settings -> About Phone -> System Updates to check for it manually, or you can just wait for it the notification to hit your phone. From there, the 14MB update will download and install, rebooting your phone in the process.
