experimenting with Magento (community edition) for a few months it appears to me like the newest version is not necessarily the best choice for everyone.
Many tutorials, templates/themes, docs and books are for 1.4. And the version 1.4 appears to be not completely comatible with the recent 1.5 version.
My question to the experienced users: what version of Magento would you prefer for setting up an entirely new shop?
When choosing an older version like 1.4, are there any security risks?
