---++ How to Find out What's New?

There are three ways to find out what's new in each TWiki web:
   1. WebChanges shows recent changes
   1. People subscribed in WebNotify get notified of recent changes by e-mail
   1. A news feed can be exported in RSS 1.0 format for TWiki:Codev/TWikiSyndication. RSS news readers like TWiki:Plugins/HeadlinesPlugin can display the recent changes

---++ RSS Feed Usage

   * The URL for an RSS feed is =%SCRIPTURL{"view"}%/&lt;web&gt;/WebRss=
   * For this <nop>%WEB% web it is %SCRIPTURL{"view"}%/%WEB%/WebRss
   * You can also create a custom feed based on a search. Add a =search=value= parameter to the URL, e.g. %SCRIPTURL{"view"}%/%WEB%/WebRss?search=plugin is a what's new feed about Plugins.

---++ RSS Feed Internals

Each web has a WebRss topic which includes part of this <nop>%TOPIC% topic. This topic is the base for the RSS feed and generates an RSS 1.0 feed for TWiki:Codev/TWikiSyndication.

The WebRss topic in each web contains the following text:

-----
<pre>
&lt;channel rdf:about="%<nop>SCRIPTURL{"view"}%/%<nop>INCLUDINGWEB%">
  &lt;title>%<nop>WIKITOOLNAME%'s %<nop>INCLUDINGWEB% web&lt;/title>
  &lt;link>%<nop>SCRIPTURL{"view"}%/%<nop>INCLUDINGWEB%&lt;/link>
  &lt;description>(the description of the web). TWiki is a Web-Based Collaboration Platform for the Corporate World.&lt;/description>
%<nop>INCLUDE{"%TWIKIWEB%.WebRssBase"}% &lt;!--
   * Set <nop>SKIN = rss
-->
</pre>

Below part is included by each <nop>WebRss topic:
