When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

"...extensions, upgrades and other changes..."
It sounds right to me. Upgrades would be the most fluent and common usage I think, although 'enhancements' could also be used. I feel comfortable with both.
All the best.

Note that 'update' would be widely used as a 'patch' or fix to an existing piece of software. There are lots of updates to windows but they do not fundamentally change the system. An 'upgrade' would be a fundamental change such as a newer software version or a software enhancement.
