At present the Auto Updater will attempt to run even when the branch is different. ie you can run 3.3.0's Auto Updater on any previous version of phpBB even though there have obviously been changes to the core files.

This has caused problems to users as can be seen in the support area. 

I feel that the Auto Updater should only run when it is the same branch as the one installed thus removing any chance of it causing errors. 

I do not know enough php to write this myself but have been told that something along these lines should work.

 

 

{{$new = '3.3.0'; // Retrieve the new version from somewhere}}

{{$new = explode('.', $new);}}

{{$old = explode('.', PHPBB_VERSION);}}

{{if ($new[0] != $old[0] || $new[1] != $old[1])}}

{{{{{ }}}}

{{     trigger_error('You can only automatically update minor versions of phpBB.');}}

{}}

{{ }}

It would save user and support members frustration and hopefully allow smoother upgrading.{}
