I get this error screen when I upgrade from 425 to 426.

We're sorry, but an unhandled error occurred. Please see the details below.
Class 'System\Twig\MediaLibrary' not found
/home/xxxx/public_html/modules/system/twig/Extension.php line 105
Is it me or the beta version of October thanks...?
Could you please take a look at the top of \System\Twig\Extension and see if it includes this line: https://github.com/octobercms/october/blob/develop/modules/system/twig/Extension.php#L9?
Hi Luke,
Thanks for your reply, yes the file:
/modules/system/twig/Extension.php
It was showing:
use System\Classes\MediaLibary;
and I manually went in and changed it to:
use System\Classes\MediaLibrary;
So when I upgraded it didn't update that file automatically.
p.s. Now I have changed that file everything is working fine again.
Ah, right. @ChVuagniaux discovered that and fixed it in a PR: https://github.com/octobercms/october/commit/c7dcd386d1462d70d3aaac098fc271ddbefdc9ad. Good to hear it's working now!
@ayumihamsaki That's it, thank you!
