Will there be any changes in the 4.5 default theme?

The reason i ask is i am using the default theme and workin on a kind of customized version for my forum, however if there is going to be a new default theme or many template changes etc to the default theme then i might hang off until 4.5 is out when ever that is. Do we have an ETA?

There is no public ETA, and yes there are certainly template changes. The general theme has not changed, but adding new features means template changes.

Ok but generaly no different to any other update with a few template changes i need to merge etc. Just didnt want to spend time doign it to find nothing is compatible. 

Its only minor changes like colours via the theme editor and custom.css and a few aditions in the index template and topics template.

I don't have a complete list of changes and 4.5 is still under active development, so there's simply no way to answer that question right now. The front-end theme has not been drastically overhauled. That said, we typically recommend doing as much work in the custom.css file (using CSS-only changes) as possible. This ensures maximum portability during upgrades.
