Upgrade Instructions

Upgrade packages are not available for this release. Install as a new release and migrate the configuration and data.

Although upgrade packages have not been built, upgrade from 2.x releases is supported. Upgrade packages will be built for the final release.

If upgrading from Foswiki 2.0.0, all working/tmp/cgisess_* files must be deleted. All users will have to log in after the upgrade. (This change was introduced in Foswiki 2.0.1.)

If upgrading from Foswiki 2.1.2 or earlier, all files in working/registration_approvals should be removed. Pending registrations will be lost.

Before upgrade, the pub/System/JQueryPlugin directory can be backed up and removed. A large number of the js and css files have been relocated. This optional step will clean up a number stale files.

If your site has configured the Expert {Sessions}{CookieRealm} setting, this release will now apply the realm to all of the cookies generated by Foswiki. This might require some users to clear their cookies for proper operation.

After upgrading from Foswiki 2.0.x, you should visit configure, enable "Expert" options, and visit the Security and Authentication > Environment tab, and "Reset" the "Name Filter" and "Upload Filter" to their default settings, in order to apply updated defaults.

The following files may be removed after upgrading from Foswiki 2.0.x to Foswiki 2.1.0:
  • pub/System/UserRegistration/js.js
  • pub/System/DefaultUserRegistration/validate.js
  • ReleaseNotes02x00.html

Upgrading from Foswiki 1.x.

Caution:There are a number of significant changes that require action before migrating data from release 1.0 and 1.1. Carefully review the release notes for ReleaseNotes02x00
  • If you have any DataForms using Unicode (non A-Za-z0-9) formfield names, you should enable the expert configuration setting: $Foswiki::cfg{LegacyFormfieldNames}
  • JavaScript is now required for many operations.
  • New default PlainFileStore cannot coexist with existing RCS revision files. If new store is selected, a conversion script must be run.
  • Foswiki now defaults to utf-8, Before importing data, you must either match previous encoding, or convert the data from the old store to the new character encoding.
  • Empty DENY rules must be changed to ALLOW * wildcards. Or the old feature must be enabled in the configuration.
  • Sessions now use IP Matching by default. If your site supports roaming / mobile users or is behind a proxy, this must be disabled.
  • Installation process has changed. Do not visit bin/configure as your first URL. Go directly to your default view url and then follow the link to configure.
  • Foswiki no longer ships with CPAN perl modules. Install CPAN prerequisites using your local system package manager, cpanm, or CpanContrib
  • Perl 5.8.8 is the minimum perl release. Perl 5.20 or higher is recommended for best performance.
  • Foswiki now predominantly uses 'single quotes' in generated HTML, and "double quotes" in macros. The change to singe quotes in generated HTML may require some rework of Foswiki macros.
  • Some versions of CGI should be avoided (especially 4.10-4.13) to prevent corruption of international characters in topics when utf-8 is enabled.
