+IMPORTANT CHANGES:

+- Starting from this release, the emulator's version number will match the
+  corresponding Android SDK Tools package revision number. The exact number
+  is extracted at build time from the Android source tree.
+
+  The minor number will now be stuck to 0 since each official emulator
+  release is supposed to match a corresponding SDK Tools release.
