Hi,
The new BSP has not been publicly released yet – we are still running final tests on it and will be releasing it next week.
There was a glitch on our side that initially marked the BSP as public, so if you checked for updates within a ~1-hour interval before we fixed it, VisualGDB would indeed show the incorrect link.
You can simply ignore it for now (or delete %LOCALAPPDATA%\VisualGDB\PackageCatalog.xml to reset the cache). Once we finish all the tests and release it, VisualGDB will use the correct link.
