SOLR-104 - Support for Update Plugins: giving RequestHandlers access to ContentStreams, new URL structure allowing for more RESTful URLs, common baseclass for RequestHandlers, refactoring existing XML based updates into a RequestHandler

@ -60,6 +60,14 @@ New Features
7. SOLR-107: JAVA API: Change NamedList to use Java5 generics
and implement Iterable<Map.Entry> (Ryan McKinley via yonik)
8. SOLR-104: Support for "Update Plugins" -- RequestHandlers that want
access to streams of data for doing updates. ContentStreams can come
from the raw POST body, multi-part form data, or remote URLs.
Included in this change is a new SlrDispatchFilter that allows
RequestHandlers registered with names that begin with a "/" to be
accessed using a URL structure based on that name.
(Ryan McKinley via hossman)
Changes in runtime behavior
1. Highlighting using DisMax will only pick up terms from the main
user query, not boost or filter queries (klaas).
