I wrote a blog post about a certain feature(in testing) of our online product.
We finished the testing and changed a couple of things and added some improvements to this feature.
So, I was thinking to update the blog post using all the new information. (The updated information is about 10-20% of the whole blog post.)
How to properly format a post update on a company blog?
1) Should I add some disclaimer at the beginning of the post to explain the update?
2) Should I add (Updated) or (Revised) to the title?
3) Should I somehow highlight the changed sentences or the whole paragraph they are in?
If you have some examples of properly formatted blog post updates - please share, they would help a lot.
