You Know What Really Grinds My Gears?
The fact Magento hasn't baked an update system in to the CMS. I'm in a new role at a company that runs three Magento shops, two of them are a version behind the most recent 1.x installation. I have to put all of them in maintenance mode, then run a shell script on each of them to do the update.
Why, in 2016, can there not be a better way of doing this? There will be retailers across the world who have no idea what's going on, and they won't know about this update. They'll dismiss the popup and think "Well the site still works so it must be OK". The computer guys who set the site up won't inform them, and if they do they'll demand a large sum of money to do the work - which again will probably result in a "No it's OK it's fine" from the retailer.
Still, it's early AM here in the UK, I'm sure the script kiddies are in bed asleep.
