Write usage examples (e.g. code snippets) for Release blog posts

[ribose-jeffreylau]

Would be helpful if some usage examples (perhaps in the form of code snippets) are available for addition of new functions, etc. in Release blog posts.

Probably it should be better to add some page like 'Usage examples', with sections, and add links to those sections from the release posts on bottom of the release post?
