Difference between magento 2.1 and 2.2

Question

I'm currently working on Magento 2.2. And found that In Magento 2.2 core team made many changes in files and folder structure, deleted many files, replaced classes and many other things.

One other important change found, that in Magento 2.2 generation folder location changed

Change location from

magento2.1/var/generation

To

magento2.2/generated

Added new folder metadata in generated folder what is use of it?

Other things found that add new i18n folder at magento22/app like Magento 1 app/locale

Does anyone has found more changes or differences in Magento 2.2?
