Hi, Currently I am using version 4.6.7. Now I want to update to 4.7.7 Beta 4  as in this beta version the Asia/Kolkata timezone issue is fixed and I can't wait till the next stable release. 

Can I update to this beta version through ACP or manual FTP upload is required?

I want to confirm this before updating because I've not FTP access, for FTP I require hosting team support.

If you create (or add to) your constants.php file, you can enable the ability to use beta builds.

<?php
define( 'USE_DEVELOPMENT_BUILDS', TRUE );

This would then make the ACP updater update you to beta builds.  

Randy had correct information so I'll just reply here offering moral support as the technical support has already been provided 🙂 .

4.7.7 final was released a little over an hour ago, so no need for the above constant to be used.
