13	13	== New field types for email and list of pages ==
14	14
15		-== Improved display of users and groups fields ==
	15	+Two new types of class properties have been added:
16	16
	17	+* The //Email// type extends the normal //String// type, adding by default a validation regular expression that should accept only a valid email address
	18	+* The //Page// type extends the normal //DBList// type, and allows to select one or more documents from the current wiki
	19	+
	20	+These two new properties are still in development, and further improvements will be implemented in the next milestone.
	21	+
	22	+== Computed class fields ==
	23	+
	24	+Another new type of class fields adds support for //virtual values// computed live from other class values, data from the database, data obtained from an external service, or practically any other source of data. These fields are non-editable and aren't stored in the database, since they only provide some wiki content that will be rendered each time such a property is displayed.
	25	+
	26	+Traditionally, this kind of computation would have been written directly in the sheet used to display instances of that class, but putting it in a class field allows easier reuse of the code, since the property will be //displayed// in livetables, when indexing the document in Lucene, when displaying documents in an index page, and so on.
