Migrating to v2

Review changes to the Tom Select API to help you migrate from v1 to v2.

Core

• Caret position functionality (using ← and → arrow keys to move between selected items) moved to caret_position plugin
• addOption() no longer treats new options as "user created" (see persist option) by default. Use addOption(option, true) for registering user created options.
• Closing control via esc key, enter, etc no longer blurs focus to maintain keyboard control
• Added sync() method
• Original <input> or <select> element uses 'hidden-accessible' styling instead of 'hidden'
• controlInput=null instead of controlInput='<input>' for hidden control input
• Deprecated isInvalid. Use isValid instead
• Removed support for querySelector('option[selected]'). Use querySelector('option:checked') instead
• Removed renderCache

CSS

• Renamed .ts-control to .ts-wrapper to align css class with name in JavaScript
• Renamed .ts-input to .ts-control to align css class with name in JavaScript
• Multiple CSS classes are now toggled on the wrapper element instead of the control element: .focus, .disabled, .required, .invalid, .locked, .full, .not-full, .input-active, .dropdown-active, .has-options, .has-items
• Removed bootstrap3 style

Settings

• copyClassesToDropdown defaults to false
