Hi,
When I run composer update on my straight SS3.0.3 install (from the silverstripe.org download link), Composer goes ahead and downloads and creates what appears to be a copy of various packages within the respective directories...
- framework/ --> framework/silverstripe-sapphire-77f7778
- cms/ --> cms/silverstripe-silverstripe-cms-d9e1bec
Are these backups of what was there before composer update?
Also, Composer adds vendor/autoload.php and a bunch of files under vendor/composer/? What are all these for?
Thank you.
VWD.
