[Should I Upgrade From 1.3.105 To Latest Version?]

I'm still on 1.3.109 and have no plans to upgrade to 1.4.  I'm waiting to see how 2.0 turns out before I decide to stay with btsync or look for alternatives.  Right now, 1.3 is working fine for me.

 

You might want to install 1.4 in a couple of VMs and test it out first before you make any kind of decision.  Doing this is what convinced me there really is no reason for me to "upgrade".

[Latest Desktop Build 1.3.109]

I got the same thing with the latest version of Crome (36.0.1985.125).  It's not a web-scanner that's throwing the error - it's Chrome itself.  The exact message is "BTSync-1.3.109.exe is malicious, and Chrome has blocked it.".  You can click the notice for more info which takes you to this link:

EDIT:  Just tried to download BTSync v1.3.106 with the same version of Chrome and there were no complaints, so it looks like it's just v1.3.109 which Chrome has an issue with.
