I'm relatively new to Magento and am currently using version 220.127.116.11.
Out payment system providers (Adyen) have recently provided a new version of their extension with better security (on gitlab this version is designated adyen-magento-2.11.1.)
I'd like to install this new version but I'm concerned that if I do it wrong it will mess up the current version that is installed. I'm assuming that I'd have to log into SSH and use a composer update but I'm unsure about where to load the files and which command to use subsequently.
I cannot seem to find any instructions about how to update this version online.
