Motorola and Verizon Wireless have been toying with us over the DROID update to Android 2.1 for the last couple of months, but it seems as though it's actually about to happen. According to Android Central, the update was approved today and will be rolled out in batches of 250,000 starting tomorrow, March 18th.

What's more, Verizon has posted the complete change log for the update:

Enhancements:

• Pinch-to-zoom is now available when using the browser, Gallery, and
  Google Maps.
• New Weather and News application plus widget.
  • The Weather and News app pulls the information you want from the
    Web and brings it to your fingertips. You get weekly and hourly
    weather forecasts based on your location, and news headlines.
• New support for voice-to-text entry.
  • Whenever a text-entry box appears, simply tap the microphone
    icon on the virtual keyboard and speak.
• New Gallery application with 3D layout. View and share photos taken
  with your phone and images from your online Picasa Web albums.
• Live Wallpapers offer richer animated, interactive backgrounds on the
  home screen. Access them with a long press anywhere on the home
  screen. Tap Wallpapers, then Live Wallpapers.

Improvements:

• Free Yahoo! Mail is now supported-simply sign in with your Yahoo!
  email address and password.
• Google Maps update.
• Personalized suggestions and synchronized starring with
  desktop maps.google.com.
  • Starred items are stored and synced automatically between Google
    Maps on your device and maps.google.com on your computer,
    making it easy to search for places you've searched
    for before.
• New night mode in Google Maps Navigation automatically changes
  the screen at night for easier viewing.
• Improved pattern-lock functionality.
• Improved handset audio when disconnecting a wired headset.
• Email accounts no longer need to be re-entered after an over-the-air update.

Expect the over-the-air updates to start at around noon (EDT) tomorrow. Presumably, additional batches of 250,000 will roll out each day thereafter. If you aren't part of the first batch and you simply cannot wait, keep an eye out for a manual update link.
