Because 12.04 has libraries that are 18 months old, and Shotwell needs 
newer versions of those libraries to fix the bugs and allow the 
features we've added.

There's a big misconception about LTS.  LTS does not mean new software 
written two years after an LTS release is expected to run on it.  I 
recommend reading this page:

https://wiki.ubuntu.com/LTS

Specifically, LTS is not:

"A Feature-Based Release: We will focus on hardening functionality of 
existing features, versus introducing new ones..."

If someone in the community wants to patch Shotwell 0.15 to run on 
12.04, they're welcome to do so.  If they do that and place it on a 
PPA, we'd be more than happy to announce it on our blog.  But I do know 
that will re-introduce some bugs we've fixed (specifically a memory 
leak we discovered in libgee) and perhaps some others, in particular 
support of various cameras, as 12.04 uses old versions of gphoto2 and 
LibRaw.
