There is good news for public facing Foswiki systems: you can now safely disable CGI sessions for guest users to gain a noticeable performance improvement. While previous releases already had that switch, user registration and password maintenance were negatively affected. Starting with this release it is safe now to deactivate CGI sessions for guests.There have been a couple of changes in how the “refresh” url parameter is used to force a new page to be generated: first, it has been removed from guest views to prevent crawlers from following the link and thus invalidating the cache. Second, only admin users are allowed to nuke all of the site’s page cache using
refresh=all. The footprint of CPAN packages required to run a Foswiki has been broadened a bit by adding LWP::Protocol::https (caused by an upstream packaging split). This will become increasingly important when foswiki.org is further moving towards an all-secure site using https. Documentation links to foswiki.org have been updated to use https only. Note that most other plugins available via foswiki.org still might link to the main site using plain http. We are working towards fixing this. We were not able to auto-redirect all http to https links yet as this was harming older Foswiki installations not having LWP::Protocol::https installed or which don’t trust our certificate. Stay tuned for more info on this.
Have a good time upgrading.
