# New features in Google Earth 6
* Integrated Street View: In Google Earth 6, the Street View experience is now fully integrated. You can enter Street View either by dropping pegman in navigation controls or by zooming in all the way to ground level on places that have Street View.
* 3D Trees:Google Earth now has trees. You can enable trees by turning on the check-box next to the Trees layer under the 3D buildings layer folder. You can see trees in several places, and we will add trees to more places over time.
* Easy to use historical imagery:When you fly to an area where historical imagery is available, the date of the oldest imagery will appear in the status bar at the bottom of the screen. If you click on this date, you’ll instantly be taken back in time to view imagery from that time period.
* Ground-level navigation: In Google Earth 6, in addition to flying around features, you can now walk on the ground to explore either 3D buildings and trees or Street View imagery.
* 3D Measurements in Google Earth Pro:In addition to measuring distances and areas on the ground, you can now measure heights and widths of 3D building and distances from buildings to the ground.

# Other changes in Google Earth 6
* Tour Recorder Improvements:With Google Earth 6, the tour recording feature has been improved in several ways. The tour recorder now incorporates the activation of Sunlight, Street View, and Historical Imagery modes into the recorded tour. Additionally, the quality of the recording has been significantly improved, including better motion fidelity and better synchronization with sound recording.
* Earth on PowerPC Mac:We are discontinuing support for Google Earth builds that work on PowerPC Macs. Users of PowerPC macs can still use the Google Earth 5.2 version.
* Earth on OS X 10.4:We are discontinuing support for Google Earth builds that work on 10.4 version of Mac OS X. Users of this version of Mac OS X can still use Google Earth 5.2 version.
* Earth on Windows 2000:We are discontinuing support for Google Earth builds that work on Windows 2000. Users of Windows 2000 can still use the Google Earth 5.2 version.
* Linux Builds:Google Earth Linux binaries are now based on the Linux Standard Base. This improves the compatibility of Google Earth on different Linux distributions, but requires users to have Linux Standard Base installed on their system. If your Linux system does not have LSB, please install it using apt, yum, smart or up2date. As a side effect of moving to LSB, joysticks are currently unsupported.
