• Support for Berkeley DB 4.8.
• Reduce errors when committing to an out-of-date pass-through proxy.
• Fix a couple of segmentation faults, one in FSFS, the other when using "svn resolve".
• "Future-proofing" the 1.6.x release line by allowing 1.6.9 to notice when the current working copy was created by a 1.7-era Subversion client.

• SiteMesh is a web-page layout and decoration framework and web- application integration framework to aid in creating large sites consisting of many pages for which a consistent look/feel, navigation and layout scheme is required.

• SiteMesh intercepts requests to any static or dynamically generated HTML page requested through the web-server, parses the page, obtains properties and data from the content and generates an appropriate final page with modifications to the original. This is based upon the well-known GangOfFour Decorator design pattern.

• SiteMesh can also include entire HTML pages as a Panel within another page. This is similar to a Server-Side Include, except that the HTML document will be modified to create a visual window (using the document's Meta-data as an aid) within a page. Using this feature, Portal type web sites can be built very quickly and effectively. This is based upon the well-known GangOfFour Composite design pattern.

• SiteMesh is built using Java 2 with Servlet, JSP and XML technologies. This makes it ideal for use with J2EE applications, however it can be integrated with server-side web architectures that are not Java based such as CGI (Perl/Python/C/C++/etc), PHP, Cold Fusion, etc...

• SiteMesh is very extensible and is designed in a way in which it is easy to extend for custom needs.
