> Changes
> -------
>
> Since version 2.7f:
>
> Bug Fixes:
> When modifying HTML links to same page are displayed as cached. Only censor
> headers for SSL if using another proxy. Don't refetch FTP files of the same
> date as cached one. Change some HTTP error codes to 500 instead of 200.
> Insert empty ALT tags when removing images. Delete zero length cached files
> when requested offline. Fix parsing of '-c' option in wwwoffle-tools.
>
> New Features:
> Added a cache-control-no-cache option which works like pragma-no-cache.
> Renamed no-lasttime-index to create-history-indexes and reversed its meaning.
> If a CGI returns a HTTP status line at the top then keep it.
> Added some web pages that will show the headers and content of cached pages.
> Allow -1 to be used for max-size and min-free to ignore the options.
> Write the unmodified header from the server to the cache when online.
>
>
> *NOTE* The URL for the URL specific index has changed.
> Instead of '/index/url/?xxx' it is '/index/url?xxx'.
>
> *NOTE* The URL for configuration page editing a specific URL has changed.
> Instead of '/configuration/xxx?url=yyy' it is '/configuration/xxx?yyy'.
>
> *NOTE* A lot of the message pages have been modified, if any of the WWWOFFLE
> generated HTML pages look different it may be a bug has been introduced.
