How to update Osclass to 8.3.0? Download files, extract and then upload via FTP?

To the question How do I update Osclass to 8.3.0? Is the answer:

add this Code: define('BETA_TEST', true); to config.php this is what it should look like:

// Demo mode
//define('DEMO', true);
//define('DEMO_THEMES', true);
//define('DEMO_PLUGINS', true);
//define('BETA_TEST', true);

then refresh the admin panel and an update aviable will appear at the head.

Sufficient just this:
define('BETA_TEST', true);

Then, once you check for udpates, you should see new one.
Or manually go there https://osclass-classifieds.com/download
And at bottom there is beta version available.

Thanks, I updated successfully. Also I translated new strings to Ukrainian language and shared to community.
