Format of the whatsnew.txt

In the root of the project, there's a file "whatsnew.txt". Any time changes are made to the repository, please update this file; add your new features at the top.

There's some special formatting rules, as this file is parsed to create the HTML you see at http://www.sws-extension.org/whatsnew.php:

• Start a line with + to make it a bulleted list
• Start a line with ! to make it a header (Header is added automatically by the build script, don't add yourself)
• URLs are automatically parsed. If you want to have a URL with different text that the actual URL, use a | symbol after the link, and after the text, eg http://link.com|Link Text|
• If you note a github issue with "issue xxx", it will automatically be converted to a link

See the existing whatsnew.txt for examples.
