I strongly recommend that anyone with a heavily customized site read 
the new customization guide. I believe that some of your problems 
have to do with the fact that your customizations were getting in the 
way of new features. 

While we made a big effort to see to it that the user interface would 
remain functional even with customizations, there was no way to have 
new functions present in existing customizations (with the new 
modular interface design, that will be less of a problem in the 
future), and some of your customizations may be incompatible with new 
features. 

One of the things we did was to make static web templates obsolete, 
so that there would not be the confusion anymore about static vs 
dynamic templates. But of course, if you had some static web 
templates customized, we made sure your customizations would continue 
to work. I suspect your "Log in" option was on such a static page, 
which by definition, is not dynamic and therefore does not change 
when you log in. I recommend moving the static customizations to the 
new dynamic versions so that you can benefit from the new features.
