• message interpolator for Bean Validation that allows a component's label to be inserted in the middle of a message
• added converters for an Iterable to List and DataModel
• new protected methods FullAjaxExceptionHandler#findExceptionRootCause() and #findErrorPageLocation() so that it can easier be subclassed

• OmniFaces depends on CDI from this version on
• injecting, converting and validating HTTP request parameters via CDI @Param
• transparent support for dependency injection (CDI and EJB) inside @FacesConverter and @FacesValidator
• new JNDI utility class
• CDI compatible @ViewScoped annotation specifically for JSF 2.0/2.1
• useRequestURI attribute for <o:form> to submit to exactly the same URL as in browser's address bar (with query string)

• new ValueChangeValidator
• new CacheControlFilter which can control cache-related headers of the response
• added SortedTreeModel which holds the <o:tree> children in a TreeSet

• added <o:deferredScript> which is capable of deferring JavaScript resources to window.onload
• <o:massAttribute> which sets the given attribute on all nested components
• FacesMessageExceptionHandler which sets any caught exception as a global FATAL faces message
• <o:cache> has new disabled attribute to temporarily disable the cache and pass-through children directly
• <o:viewParam> skips converter for null model values so that query string doesn't get polluted with an empty string

• NoAutoGeneratedIdViewHandler which throws a runtime exception when an autogenerated JSF client ID is being rendered
• <o:viewParamValidationFailed> which enables sending either a redirect or error status on validation failure of view parameters
• <o:graphicImage> which is capable of referencing a byte[] or InputStream property with optional support for data URI format
• <o:moveComponent> via which components, facets and behaviors can be moved at runtime to a target component in various ways
• <o:resolveComponent> via which a component can be looked up by its ID and a reference to it put in various scopes
• <o:validateBean> now supports validating beans at the class level

• <o:tagAttribute> to explicitly declare a tagfile attribute which is only exposed in tagfile's own EL scope, to prevent pollution in EL scope of nested tagfiles
• FacesConfigXml to get faces-config.xml entries which are not available via native JSF API (currently only a mapping of all <resource-bundle> entries can be obtained)
• <o:graphicImage> now also supports SVG images with explicit type="svg" attribute and fragment attribute for SVG view modes
• @Cookie to inject a HTTP request cookie in a CDI managed bean
• CombinedResourceHandler now supports server-side caching of combined resources via org.omnifaces.COMBINED_RESOURCE_HANDLER_CACHE_TTL context param
• @Eager now also supports JSF 2.2 javax.faces.view.ViewScoped

• Second life for @ViewScoped
• FileServlet - New FileServlet with advanced HTTP range and caching support
• <o:viewAction> - Fix unintuitive "if" attribute of <f:viewAction>

• @ViewScoped - Improved
• <o:socket> - For web socket based push which can be accessed via CDI @Push
• <o:skipValidators> - To skip all validation during a UICommand action or an ajax request
• FileServlet - Supports customizing 404 error handling and attachment file name
• Beans#fireEvent() - To fire a CDI event object
• More utilities - Beans#isActive(scope) | of:formatThousands() | of:formatThousandsUnit() | of:formatNumberDefaultForLocale() | Faces#getViewName() | Ajax#load() | Servlets#getRemoteAddr()

• Components#getCurrentActionSource/ActionExpressionsAndListeners() - Which should ease a.o. logging JSF ajax actions
• <o:url> - Which fills the gap caused by absence of JSTL <c:url> in Facelets
• FullAjaxExceptionHandler - Got new logException override which allows determining the log reason
• of:reverseArray() - To reverse an array
