## <a name="How to Find out What&#39;s New?"></a> 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
2. People subscribed in [[WebNotify]] get notified of recent changes by e-mail
3. 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

## <a name="RSS Feed Usage"></a> RSS Feed Usage

- The URL for an RSS feed is `http://www.dementia.org/twiki//view/<web>/WebRss?skin=rss`
- For this %WEB% web it is <http://www.dementia.org/twiki//view/%WEB%/WebRss?skin=rss> (or [http://www.dementia.org/twiki//view/Main/WebRss?skin=rss&amp;contenttype=text/plain](http://www.dementia.org/twiki//view/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. [http://www.dementia.org/twiki//view/%WEB%/WebRss?skin=rss&amp;search=plugin](http://www.dementia.org/twiki//view/%WEB%/WebRss?skin=rss&search=plugin) is a what's new feed about Plugins.

## <a name="RSS Feed Internals"></a> RSS Feed Internals

Each web has a [[WebRss]] topic which includes part of this %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:

----

    <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"}%

Below part is included by each WebRss topic:
