Assignments - Submission History field for Assignment Submissions has been removed in Sakai 12

Sakai 11 shows a submission history for an assignment. This submission history in the user interface was removed as part of the Sakai 12 assignments tool refactor. A replacement is being explored at

Assignments - Site Archive is no longer compatible between Sakai 12 and earlier versions of Sakai

The Assignment XML that is exported in Sakai 12 is significantly different than in Sakai 11 and earlier. 

Assignments - For Attachment only assignments, student must upload a file. Links are not accepted.

The option "Select files from workspace or site" has been removed for Attachment only assignment types to prevent students from submitting a URL to a mutable document, like a Google doc, which potentially could be altered even after submission and due date have passed.

Bullhorn Notifications - A new feature which is off by default in 12

Bullhorn notifications is off by default in Sakai 12. It is for academic and social notifications. To be turned on by default in the future, some work may be needed to identify the desired behavior, which activities should generate notifications, which should not, and which potentially create double notifications, and then addressing those gaps to have desired default behavior.

MathJax - now a site level instead of a tool level setting

MySQL and MariaDB - upgrade to Hibernate resulted in new dialect

hibernate.dialect=org.hibernate.dialect.MySQL57InnoDBDialect

Profile tool "wall" disabled by default in Sakai 12

Signup tool properties documented

The properties options have been updated in default.sakai.properties. No new properties have been added, just that existing properties have been documented. 

Site Management - Duplicating sites disabled by default due to performance concerns

A JIRA is open, but not PR (pull request, aka source code contribution) for it yet. 

Syllabus - editing process has changed

Syllabus items can no longer be edited in place. Instead you must use the Bulk Edit UI. There is a request (Jira) to change the name of Bulk Edit to just "Edit" since this is the only option for editing a Syllabus item in Sakai 12. 

Test and Quizzes - Autosubmit in Samigo Tests and Quizzes always includes submission even if only partial

Doesn't affect when take highest score is in effect, but does impact average scoring of submissions or taking the score of the latest submission. There is a JIRA (not yet in 12) to update the text that is displayed to instructors and students, 

Web Services

Please note that the default for webservices.log-allowed has been changed from true to false.

Sakai 12 properties

----------------------------------

Recommend storing files on your file system instead of database

Sakai will store the file content in the database as BLOBs by default. Set this value to change it to store the content on the filesystem instead.

The file system root for content hosting's external stored files (default is null, i.e. store them in the db). 

# bodyPath@org.sakaiproject.content.api.ContentHostingService=/someplace/

# KNL-309 : To enable support for deleted files set this property to some location

# bodyPathDeleted@org.sakaiproject.content.api.ContentHostingService=${sakai.home}db/bodyContentDeleted/

# When storing content hosting's body bits in files, an optional set of folders just within the bodyPath -

# to act as volumes to distribute the files among - a comma separate list of folders.  If left out, no volumes will be used.

# see the readme file (2.2.7 File Based Content Hosting) for more details

# bodyVolumes@org.sakaiproject.content.api.ContentHostingService=vol1,vol2,vol3

# Set to true to enable the release/retract and hiding of resources in ContentHostingService, Default: true

# availabilityChecksEnabled@org.sakaiproject.content.api.ContentHostingService=true

# Set to true to enable custom sorts within folders in ContentHostingService and the Resources tool

# DEFAULT: true

# prioritySortEnabled@org.sakaiproject.content.api.ContentHostingService=true

You might also want to enable the soft deletion feature of Sakai

Soft site deletion. 

If enabled, sites that are deleted will be inaccessible to normal users but won't be deleted immediately, in case they need to be recovered.

You also need to set the gracetime value, in days. After this period, the softly deleted sites will be hard deleted. Defaults to 30 days.

There is a Quartz job that must be configured to run periodically (once per day or so) to expunge those sites.

site.soft.deletion=true (default is false)

 site.soft.deletion.gracetime=30

Lessons management of HTML pages

By default, Lessons uses Content Security Policy headers to restrict what an HTML page can do, when the page is loaded from Sakai.

This is a security tradeoff. There are security risks from opening a web page written by someone else. That page can contain Javascript, which will execute with your own permissions. For this reason, by default Sakai will not open web pages in Resources. If you click on an HTML file there, it will download. We considered this inaccessible for Lessons, since the whole point of Lessons is to present content online. But we still had to deal with the security problem. So the page is served with an HTTP header that causes browsers to open the page in a “sandbox.” This restricts what the page can do.

This is new in 11. In Sakai 10, Lessons would simply open any HTML page specified.

You can restore the Sakai 10 behavior by adding the following to sakai.properties:

lessonbuilder.use-csp-headers=false

The recommended approach for dealing with this security risk is to use Sakai’s content domain support. This causes HTML pages stored in resources to be served from a different hostname than the main Sakai hostname. E.g. if your institution uses sakai.univ.edu, you might use content.sakai.univ.edu for content, resulting in URL such as https://content.sakai.univ.edu/access/content/group ….  Using a separate domain prevents web pages from executing with your Sakai privileges. Thus if you are using a separate content domain, Lessons does not add the Content Security Policy headers.

Note that it is up to the browser to enforce Content Security Policy. Safari, Chrome, and Edge do. Firefox does not. Thus Firefox users are still at risk when opening HTML pages in Lessons. I believe IE 10 and 11 also support it.
