Should I migrate from Django 1.2.5 to 1.3.x ?  Are there any undocumented issues?
As I once read somewhere, Django has releases mostly because people ask about releases. Other than that, it's perfectly ok to stick to the trunk revision.
Short Question
Are there any compelling reasons to update Django 1.2.5 to 1.3?  If the noted changes in the release notes do not impact my application directly.
EDIT:
To better clarify my question (thanks S.Lott!): Are there any issues not mentioned in the Django 1.3's release notes that I should be aware of if upgrading from version 1.2.5?
Background
I have done all of my development on 1.2.5 with no troubles.  I will be deploying my application within the next week or two and it's life cycle will be 18 - 24 months of constant use.  
Secondary (more general question)
Just  prior to a release, is it good practice to get the latest and greatest (stable) version of your dependencies?
