Change Log

When converting from XML to an array, use the 'id' or 'name' element as the array key value.

Add a 'list delimiter' formatter option, so that we can create a Drush-style table for property lists.

Breaking The RenderCellInterface is now provided a reference to the entire row data. Existing clients need only add the new parameter to their method defnition to update.
Rename AssociativeList to PropertyList, as many people seemed to find the former name confusing. AssociativeList is still available for use to preserve backwards compatibility, but it is deprecated.

Add RenderCellCollections to structured lists, so that commands may add renderers to structured data without defining a new structured data subclass.
Throw an exception if the client requests a field that does not exist.
Remove unwanted extra layer of nesting when formatting an PropertyList with an array formatter (json, yaml, etc.).

Breaking The default string format now converts non-string results into a tab-separated-value table if possible. Commands may select a single field to emit in this instance with an annotation: @default-string-field email. By this means, a given command may by default emit a single value, but also provide more rich output that may be shown by selecting --format=table, --format=yaml or the like. This change might cause some commands to produce output in situations that previously were not documented as producing output.
Breaking FormatterManager::addFormatter() now takes the format identifier and a FormatterInterface, rather than an identifier and a Formatter classname (string).
--field is a synonym for --fields with a single field.
Wildcards and regular expressions can now be used in --fields expressions.

Add tab-separated-value (tsv) formatter.

First stable release.
