2006-06-08

• Change: Added the gsp mime type for files created with Geometer's sketchpad. (Alex Chapin)
• Change: Changed how RSS feed links are displayed in the pop up window for more RSS. Specifically added RSS icon and made the description of the RSS feed the link to that RSS feed. (Alex Chapin)
• Change: Added the text RSS to the right of the RSS icon for the link to page RSS. As well added the RSS icon to the left of the more RSS link for additional RSS feeds. (Alex Chapin)
• Change: There has been a problem with inadvertant session-hijacking. This is caused when a user (with cookies diabled and the PHP Session ID passed in their URL) copy/pastes a Segue url containing the session ID into an email or external website. When students (or others click on that link, they are now using the session with the id specified in the url. Multiple users clicking such a link would all end up using the same session, causing login/logout actions of one user to apply to state of all users who clicked that link. As there is no technological trick in PHP that would allow the continued passing of the Session ID in the URL without this problem, Segue will now force the use of cookies for authenticated users. (Adam Franco)
• Change: Changed display of sections with single pages. Specifically, when a section has only one page, a sidebar link is still created. (this change undoes a new feature introduced in version 1.5 whereby sections with only one page would not display a link to that page in the left sidebar). To avoid confusion as well as inform users of options, when a section has only one page, a note is displayed at the top of the sidebar indicating the section has only one page and a link is provided to change the section display settings to hide the sidebar. (Alex Chapin)
• New feature: Added section display options. Specifically added a display option to hide sidebars. When this option is selected, both the left and right sidebars are hidden and if the section has more than one page, links are displayed to the previous and next pages. If this section setting to hide sidebars is turned on, then a note is displayed at the top of each sidebar indicated this and a link is provided to change the section display settings to show the sidebar.

• Bug Fix: Added missing enclosure tags to all-content RSS outputs. (Alex Chapin)

• Bug Fix: Set encoding of RSS feeds that are displayed in Segue (via CARP) to be utf-8 (had been set to ISO 8859-1) (Alex Chapin)
• Bug Fix: Fixed spacing between content blocks to make more consistent. Specifically, if no attribution or no horizontal rule, then a single space is put between content blocks. If horizontal rules specified, then no space is put between content blocks. (Alex Chapin)
