Winter 16 – API 35

The Winter 16 (API 35) release has no substantial impact on the accuracy and recommendations in the book.

Details on Individual Changes

Running individual unit tests

Chapter 10 – You can now run individual tests in a test class! The book noted that this was possible using the tooling API and expressed a hope that it would be soon available in the UI. Our wish has been granted.

Roll0up Summary field Limits

Chapter 11 – You can now have 25 roll-up summary fields on an object. You can have up to 7 external ID fields.

That said, the recommendation to avoid using these field types in a managed package stands, as these limits are global to the object and not specific to each package.
