Laravel data v4 update

[rubenvanassche]

We've been working for quite a while on data v4 in the beyond-data branch with some excellent new features like:

• Arrays, Collections, and Paginators are now valid DataCollections
• Addition of the collect method and removal of the collection method
• Magic data collections
• Rewritten partial trees resolving
• Dto and Resource classes
• And a lot more

We planned to release data v4 around this period with a revamped validation system that would once and for all solve our validation problems. Sadly enough, this was much more than expected, and it will take a few more months to get it all together.

So this is the plan: we'll release data v4 without validation changes in the following weeks. In the meantime, we're working on a laravel-data validation spec that describes how the validation works and should be implemented. This spec will guide us through the successive iterations of laravel data to create an even better package.

As soon as the spec is internally reviewed here at Spatie, we'll share it on GitHub and start implementing it. We can then release laravel data v5 with revamped validation quickly!
