Download SDK
Check this page periodically for latest SDK builds. To understand better what kind of changes we brought
in new build version, see build version in "Library" column. Form is: Build-{Major}.{Minor}.{Build}.{Revision}.zip.
If you see {Major} or {Minor} version numbers different than version you are using, you should update your SDK
since some existing functionality might be altered or removed, as well as new added.
