DotNetNuke 4.5.4 is mostly a stabilization release along with one enhancement (SSL support) that has been requested for a long time by the DotNetNuke community.
Joe Brinkman explains that the SSL was added in this stabilization release mostly because it was low risk and would not interfere.
If you are interested in a rather lengthy discussion that occured in the forums about the new SSL support you can find one here:

I have created a tutorial on the new SSL feature here: Setting up SSL in DNN 4.5.4+
The table below has a list of all the changes made in this release. Feel free to ask any questions you may have on the SSL or these changes and I'll do my best to answer.
