Notes on Upgrading to NanoBlogger 3.2.3

I received an email from an Alexander Griesser describing the difficulties he encountered when trying to upgrade NanoBlogger to 3.2.3 from 3.1.

Here's an excerpt:

Today I upgraded my nanoblogger installation from 3.1 to 3.2.3 and all entries in the sidebar were empty. After investigating, the reason was that you changed some variable names, e.g NB_Recent_Entries to NB_RecentEntries and my templates/main_index.htm contained the old variable name.

I'm sharing this email in the hope that it may be useful for other people that would like to upgrade. I'd also like to note that I do maintain a list of template variables in NanoBlogger's User manual. The reason for all of the renaming, was that I wanted to achieve more consistency between all the different variable names. The rule of thumb is, if it contains more than one underscore, remove the second to last.
