I would just like to share the information I got regarding the latest Build 10586.494 since I was not able to find a reference yet here on the Community. Microsoft Moderators and Engineers please verify this post and confirm if the details below are correct. This is my first to post a discussion. Please don't judge. :)
As per the resource article I found: Microsoft has now pushed Windows 10 Mobile Build 10586.494 to both insiders in Release Preview Ring and non-insiders as the Windows 10 Mobile July Cumulative update. The Build as expected brings many fixes and improvements over the last release build 10586.420.
