0.3.1 to 1.0.0 Migration Guide

Work In Progress

Introduction

The 1.0.0 release of CAM finished adding support for all ARIA roles. It also brought in some bug fixes and improvements, some of which are breaking changes that lead to multiple 1.0 pre-release versions of CAM before the 1.0.0 version was released. These breaking changes can be broken into the following categories.

Role Splitting

• ROLES.OPTION has been split into ROLES.SINGLESELECTOPTION and ROLES.MULTISELECTOPTION. This was needed in order to support getting ROLES.SINGLESELECTLISTBOX working visually consistent across browsers combined with CAM's one-to-one role to HTML tag mapping.

If an option is being added to a ROLES.SINGLESELECTLISTBOX, then replace ROLES.OPTION with ROLES.SINGLESELECTOPTION. For options added to ROLES.MULTISELECTLISTBOX, then replace ROLES.OPTION with ROLES.MULTISELECTOPTION.
