Thank you David.

Are there step-by-step instructions on how to upgrade?

For core update, Oxwall software documentation says, "Auto-update is all about clicking a button in admin area and entering your FTP details." Where exactly in admin area do we enter our ftp details? I can't see any option...

Example. Goto Plugins. You will see Platform Upgrade. Select that and It'll ask for your FTP details....

Thank you for replying. Checked the plugin area but there is no such plugin.

Shreya Tili, also updates are displayed in admin panel's dashboard.
If you have not got "Update Platform" notice, means that CRON is not set.
Note that it takes some time for this notice to appear. A day or two.

How do I set the cron?

We have informed our members that the upgrade will be happening on Friday so I would like this in place before that, if possible.

I waited this new release only for mobile version..I'm very sad...:-(

Daniele if there was a mobile plugin it would have been 1.6 or 2.0 since its major

Thanks Aliia. I just checked and the cron job is already running. Attached a screenshot. Still, no green balloon or update link.

Hi Suresh...probably you are right...but I had a little hope...:-(

Can someone pls reply to my query? I have cron job running but still NO green balloon for update.

Just to let you know that we've managed to update successfully. Went down the manual installation route.

For my site http://www.bookerzmedia.com, the auto update has not appeared.

Set up your CRON using  instructions under "Run Cron Locally" section of the manual here: http://docs.oxwall.org/install:cron
