* As with WeBWorK 2.16, third party javascript libraries (jquery, jquery-ui, mathjax, codemirror, etc.) are installed via npm. WeBWorK 2.17 does even more. Now WeBWorK's own javascript and css files are minimized, and generated with a filename containing a hash of its contents. This means that users will not need to clear their browser cache when WeBWorK is upgraded. In addition if you would like to serve third party javascript from a remote CDN instead of serving these files from your server, there is an installation option to set that up.

New WeBWorK Features

  • As with WeBWorK 2.16, third party javascript libraries (jquery, jquery-ui, mathjax, codemirror, etc.) are installed via npm. WeBWorK 2.17 does even more. Now WeBWorK's own javascript and css files are minimized, and generated with a filename containing a hash of its contents. This means that users will not need to clear their browser cache when WeBWorK is upgraded. In addition if you would like to serve third party javascript from a remote CDN instead of serving these files from your server, there is an installation option to set that up.
  • Students may now attach files to emails they send to instructors via the "Email Instructor" page.
  • The look and feel of the user interface of WeBWorK is quite different, mainly because Bootstrap has been updated from version 2.3.2 to version 5.1.3. This gives a much more modern feel.
  • The theming of WeBWorK has changed significantly. Themes written for previous versions of WeBWorK will no longer work. See Customizing WeBWorK for information on how to create new themes.
  • Instructors may now create sets with spaces in the name. Technically the spaces are translated into underscores and the set names are stored that way, but anytime a set name appears in the user interface it will be shown with spaces.
  • It is now possible to delete a specific version of a Gateway quiz for a student. This can be done on the page opened when you click on the "Assigned Sets" column for a user in the Classlist Editor.
  • When a student clicks "Grade Test" in a gateway quiz, a confirmation dialog will open that informs the student of the consequences of submitting the quiz and gives the student a chance to decline submission.
  • Gateway quiz versions are no longer listed on the course homepage (the Homework Sets page). Instead they are listed on a page that opens when you click on the Gateway quiz template. This page also gives the student more details on the Gateway quiz and displays a set info much like the problem list page for regular homework sets. If you are using LTI authentication and provide direct links to homework assignments or quizzes, then it is recommended that you now direct the students to this page for Gateway quizzes rather than directly into the the quiz. So use a link that looks something like "https://yourserver.edu/webwork2/courseID/setID" instead of "https://yourserver.edu/webwork2/courseID/quiz_mode/setID".
  • Some LTI authentication mode parameters can now be set in a new tab on the course configuration page. This new tab is available if any of the entries of the @LTIConfigVariables array in /opt/webwork/webwork2/conf/authen_LTI.conf are un-commented.
  • There is a new permission "navigation_allowed". This permission can be set on the "Permissions" tab of the course configuration page and is labeled "Allowed to view course home page" there. This permission is intended to be used with LTI authentication when grade passback mode ($LTIGradeMode) is set to "homework". If a user does not have this permission, then the user will not be allowed to view the course home page (the list of homework sets) or the "Grades" page, and links will not be available to access any set other than the one the user signed in to view. Usually this permission would be set to login_proctor in this case. If using this permission, then you will need to ensure that a link is provided to each homework set in your LMS.

New PG Features

  • All support for Java and Flash applets has been removed (there is now a warning shown for existing problems).
  • Three new graphing tools were added to the GraphTool macro (parserGraphTool.pl): a point tool, a three point quadratic tool, and a four point cubic tool. Furthermore, keyboard controls have been added. This is important for users with mobility impairments, and can be useful for other users having difficulty placing points accurately on the graph.
  • The Drag/Drop macro (draggableProof.pl) has been updated, and if problems are written correctly these problems will now work in Gateway quizzes.
  • There have been many improvements to Mathquill for both parsing mathematical expressions and units.

Security/Advanced Features

  • The SOAP module is now disabled by default. You will need to set $WeBWorK::SeedCE{soap_authen_key} in /opt/webwork/webwork2/conf/webwork2.apache2.4-config to something secure.
  • When hard copies of homework sets are generated, the generated files are no longer placed in a publicly available location on the server. Instead they are generated in the /opt/webwork/webwork2/tmp directory, and served via mod_perl2. Only the user that generates the file will have access to the file over the internet. Furthermore, on successful generation, all files are deleted from the server after the resulting pdf or zip file are served including the served file itself. On failure the files are not deleted so that the user can download them for diagnosis of the failure, but the user will only be able to access those files as long as the page is still open in WeBWorK. See issue #1075 for details on why this change was made.

Upgrade Instructions

  • First update the webwork2 and pg code. You will most likely need to first delete the package-lock.json file. For this run
    > cd /opt/webwork/webwork2
    > rm htdocs/package-lock.json
    > git fetch origin
    > git checkout main
    > git pull
    > cd /opt/webwork/pg
    > git fetch origin
    > git checkout main
    > git pull
  • The default branch in Github for the OPL repository (https://github.com/openwebwork/webwork-open-problem-library) is now main instead of master. If you have a local clone with the old master branch, then you can switch to main with
    > git branch -m master main
    > git fetch origin
    > git branch -u origin/main main
    > git remote set-head origin -a
    in /opt/webwork/libraries/webwork-open-problem-library.
    If you get an error like fatal: couldn't find remote ref refs/heads/master when doing the git fetch origin
    check if you have a line in .git/config in the [remote "origin"] section like
    fetch = +refs/heads/master:refs/remotes/origin/master
    and if so replace it with
    fetch = +refs/heads/main:refs/remotes/origin/main
  • There have been significant changes to /opt/webwork/webwork2/conf/webwork.apache2.4-config.dist. So make sure that you integrate these changes into your copy of that file and the active version which is /etc/apache2/conf-enabled/webwork.conf (or something similar depending on the base OS's apache config file location).
  • WW 2.17 requires the apache rewrite module (mod_rewrite) to be enabled. On Ubuntu systems run: sudo a2enmod rewrite
  • The following perl packages will need to be installed (run bin/check_modules.pl to ensure you have all programs/modules)
    • Email::Stuffer (on Ubuntu install the package libemail-stuffer-perl)
    • YAML::XS (on Ubuntu install the package libyaml-libyaml-perl ... yes two libyaml's)
  • Instead of running pdflatex /opt/webwork/webwork2/bin/check_latex.tex (which will fail), run check_latex. That script will tell pdflatex where to find the necessary webwork2 common tex files.
  • Run npm install in the htdocs directories to upgrade third party javascript libraries. This will also minimize the local javascript and css files. WW 2.17 requires newer versions of node and npm to do this. The javascript and css used solely by PG has been moved into /opt/webwork/pg/htdocs. This means that npm will also need to be run in that location as well.
  1. Install node and npm:
    • On Ubuntu:
      > curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -
      > sudo apt install nodejs
    • On CentOS/RHEL:
      > curl -fsSL https://rpm.nodesource.com/setup_16.x | sudo bash -
    • On RHEL 8 (whenever dnf is available):
      > sudo dnf module reset nodejs
      > sudo dnf module enable nodejs:16
      > sudo dnf module -y install nodejs:16/common
  2. Then run npm to install (or upgrade) third party javascript and minimize local javascript and css:
    > cd /opt/webwork/webwork2/htdocs
    > npm install
    > cd /opt/webwork/pg/htdocs
    > npm install
    Optionally, you may want to serve third party javascript via a CDN. If so, then change the above npm install commands to
    > USE_CDN=1 npm install
  3. Upgrade the Database
    • > upgrade_admin_db.pl
    • Logon to the Admin course
    • Navigate to the "Upgrade Courses" tab.
    • Complete the upgrade to all desired courses.
  • There have been updates to the Open Problem Library as well.
    • Running OPL-update is a necessary step when upgrading to 2.17.
      • > cd /opt/webwork/libraries/webwork-open-problem-library
      • > git pull
      • > OPL-update
    • The process has been streamlined so that it no longer takes 20+ minutes to import the OPL.
    • You will be asked to share OPL usage statistics with the community, please consider doing so (no student information will be included in the shared data).
    • Now, any course containing a Contrib sym-link in the templates folder will have an additional option on the Library Browser to include Contrib/ problems in their search. To accomplish this:
      • > cd /opt/webwork/courses/YourModelCourse/templates
      • > ln -s /opt/webwork/libraries/webwork-open-problem-library/Contrib Contrib
        • if the previous instruction requires sudo permissions, then make sure you also
        • > sudo chown -h www-data:www-data Contrib

Call for Translators

Much of the text has changed in the WeBWorK interface, so there are new entries that need to be translated into other languages. If you would like to help in translating a language, please go to Transifex and click on `Help Translate "webwork2"`. You will need to create a Transifex account (this is free, contrary to the remarks about a free trial). Then request to join the translation team for the language you will work on. If you would like to work on translating a language that is not yet in WeBWorK, you may also request to add a new language. If you have helped with translating a language for WeBWorK in the past, note that we will no longer be accepting direct pull requests to the webwork2 repository on GitHub for translations. This will all be done via Transifex.
