I have 2 storefronts built with 4.3, and they are about to go live. They also have a couple paid plugins and a little bit of custom code.
Should I leave 4.3 and launch my sites as they are? Or is it worth it to upgrade these to 4.4 first? I guess there are some large benefits with performance with 4.4.
How much time should I allocate to the upgrade process?
When is 4.5 coming out ? Is it better to wait for that?
I'm looking for opinions based on your experience so far.
