1. Debug Mode for Lightning Component- Now set the debug logs for specific users instead of complete org or all the users.

2. Lightning Component Library Is Available On Developer Forum – Yes, you heard it right!! Lightning component library is generally available with great examples, demos and documentation.

You can also access your Org specific lightning component as well in, just append “componentReference/” after your Org URL. More details here

3. SLDS class names updated – Now SLDS classes which were having the double dash (–) in the name, will have single underscore (_). So you may want to update your class names. Although always prefer Lightning Components over SLDS classes for better compatibility. Also, slds-form_inline (formerly slds-form–inline) style was removed.  More details here

Do you feel need to have single component instead of 2 difference component for editing and viewing? Well, lightning:recordForm is here to fulfil this wish. Use this component to add, view or edit a record. Isn’t it awesome !!
