We recently discussed open-source, web 2.0 eCommerce software (Script) “Magento” - Its still beta and got updated today.
New version is 0.7.14800 and now includes new kind of installer and automated package upgrades, what does it mean?
When you download and unpack the installer package on your server, the installer wizard downloads and installs the latest available Magento Packages directly to your server. Since the installer has a smaller file size, you don’t have to upload every file to your server - it only contains the bootstrap files (the files necessary to run the installer itself, and basic configuration for Magento).
even already installed Magento shop can now be updated with one click from the admin panel. From now on you can go to: System -> Extensions -> Remote screen and view there installed and available packages, also from there you can check for upgrades.
