new presta vs 1.2.1 version

[Octahedron]

Hi Folks,

I am on Presta 1.2.1 at the moment but have modified the shop quite considerably. Am wondering if there were any serious bugs in ver 1.2.1 and if there's any point in upgrading to 1.2.4? I haven't noticed anything going wrong with my current version and would not like to go through the painful process of amending the new version and upgrade if it doesn't look the way I want it straight away.

Can you please point out the most important improvements of the new version that are good enough reason to upgrade?

Cheers!
