Fred: questions about the creation of PB4 ? =)

[USCode]

Hi Fred,
When you have some free time...
...just a couple questions about the whole creation process of PB4:

- Of all the changes to PB4, what do you consider to be the most "significant"?

- How long has it taken so far to update PureBasic to version 4?

- Looking back, anything you might have done differently? (maybe too early to answer this one)
