I recommend waiting a month to install this update, due to Synology's egregious pattern of recalling updates and then re-releasing patched updates with the same build number.
When that happens, early adopters are unable to install the corrected patch. And we know that Synology's first patch release often introduce new deficiencies. I, for one, am stuck on a "release 2" version that was twice replaced. But I'll not repeat that, jumping to an early "release 3" build.
It's my hope that some here who have a relationship with Synology would use their influence to end this poor practice of releasing "patched" patches without advancing the build number.
