---++ 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%SCRIPTSUFFIX%/&lt;web&gt;/WebRss?skin=rss=
	* For this %WEB% web it is %SCRIPTURL%/view%SCRIPTSUFFIX%/%WEB%/WebRss?skin=rss (or %SCRIPTURL%/view%SCRIPTSUFFIX%/Main/WebRss?skin=rss&contenttype=text/plain for plain text RSS)
	* You can also create a custom feed based on a search. Add a =search=value= parameter to the URL, e.g. %SCRIPTURL%/view%SCRIPTSUFFIX%/%WEB%/WebRss?skin=rss&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:

-----
<verbatim>
<channel rdf:about="%SCRIPTURL%/view%SCRIPTSUFFIX%/%INCLUDINGWEB%">
  <title>%WIKITOOLNAME%'s %INCLUDINGWEB% web</title>
  <link>%SCRIPTURL%/view%SCRIPTSUFFIX%/%INCLUDINGWEB%</link>
  <description>(the description of the web). TWiki is a Web-Based Collaboration Platform for the Corporate World.</description>
%INCLUDE{"%TWIKIWEB%.WebRssBase"}%
</verbatim>
-----

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