• You can now ban IP addresses from using your Philter. Add banned IP addresses to the text field located in the configurator script, Miscellaneous Settings.

MetaPhilter 1.0

April 24th, 2003

• The common form template 'form_admin_profile.tmpl' had some poor templating that caused users to be "degrouped" when editing their profiles. Fixed. Please replace your former templates with the new one if upgrading.

MetaPhilter .9

April 20th, 2003

• The included RSS index is now in RSS 2.0

• Unicode characters no longer mangled into garbage HTML entities when previewed or edited.

  • MPUserData

  • MPUserGroup

  • MPUserPreference

  • MPIfUserGroup

  • MPIfUserPhilter

  • MPIfUserPermission

  • MPUserSince

  • MPUserLastVisit

  Using these tags without nesting them in user, link, or comment, containers saves processing time when only information of the logged in user is needed.

• The MPUser tag from the "Recent content" sidebar in the common template 'index.tmpl' has been removed to comply with the new "smart tag" design of user data tags.

MetaPhilter .77

April 15th, 2003

• Tag object's ancestor() method no longer uses array_change_key_case(). This should push requirements back to PHP 4.1 (though 4.3.0 is still preferred).

MetaPhilter .76

April 14th, 2003

• The <MPFormData select="content"/> tag in 'form_comment.tmpl" has been changed to <MPFormData select="content" literal="yes"/> to prevent lost entities when previewing comments.
