Google Releasing Google Earth 4.3 Today

New features include

Street View inside Google Earth - As rumored weeks ago, Street View will be here soon. And, yes - the images will be viewed with the Photo Viewer. That answers that question.

Imagery Dates - You will now be able to easily see the dates when imagery was taken for most imagery (but, not all - simply because the date data isn't always available from the many imagery providers delivering to Google).

New navigational controls - New features enabling better ways to look around at 3D buildings and 3D terrain using new navigation gadgets and your mouse or keyboard.

More 3D buildings, faster loading - Faster loading 3D building models, and faster rendering as well. New photo-textured cities (it will be interesting to find out how they were made, where they came from, and how many new cities are included).

Day/Night Lighting - Real-time sunlight lighting option. Time slider control of the sun position. Expect a more realistic looking view of Earth from space. This has been done before by others, but now will be available built-in and supported by Google.

Flash Support for Mac - That's right, you'll now be able to play YouTube videos and put other flash apps inside Google Earth placemarks just like on Windows. There may be a couple of caveats though from reports I have. More on this later.

Switching to Sky Faster - Switching between Sky and Earth modes will be much faster.
