Important Changes

1. Added protection against CSRF (cross-site request forgery) in TWiki 4.3.2 patch release

TWiki protects content updates with a one-time-use crypt token to guard against CSRF exploits. This means that it is no longer possible to hit the browser back button to fix a typo; you get an "invalid crypt token" error message if you try to save again. Workaround: Instead of browser back button, hit the "Edit" button to fix a typo.

There is a balance between security and user convenience. A TWiki administrator can enable and disable the crypt token based CSRF protection with the {CryptToken}{Enable} configure setting. For mission critical public TWiki sites it is recommended to enable the crypt token; for firewalled TWiki sites it is usually OK to disable it.

Deprecation Notices

The %MAINWEB% and %TWIKIWEB% variables have been deprecated. For compatibility reasons they are unlikely to ever be removed completely, but you should use the %USERSWEB% and %SYSTEMWEB% variables instead.

In Func getOopsUrl and permissionsSet have been declared deprecated. There is no plan to remove them yet.
