httpd has been upgraded from 2.2.13 to 2.2.14. This upgrade involves only bugfixes. Details may be found at http://www.apache.org/dist/httpd/CHANGES_2.2.

varnish was upgraded from the 2.0.x to the 2.1.x version series. 2.1.x has a change in the varnish configuration language syntax that is incompatible with the older versions.

The main change is as that obj.* is now called beresp.* in vcl_fetch, and obj.* is now read-only. For more information, please refer to http://varnish-cache.org/wiki/changelog_2.0.6-2.1.0.
