Never really thought through where those should go. They now point to the published version.
% rake upgrade_instiki fixes some potential problems in the database column types. Revision content can now be up to 16MB. Under MySQL, the previous limit was 64KB. Page names can now be up to 255 bytes. Under MySQL, the previous limit was 60 bytes. Additional CSS styles can now be up to 64KB. Under MySQL, the previous limit was 255 bytes. Thanks to Andrew Stacey for reporting these.
When redirected to another page, flash messages will not display if the query string is longer than 10192 bytes. In Instiki, certain rescue operations involve redirection, with the updated content of the page passed as a query parameter. Fall back to using the stored content (ie, don't pass a query parameter) if the content is too long.
