Cautions

Warning : Because new tables and fields have been added to the OpenProblemLibrary and for new MathAchievement features upgrading from stable webwork (WW-2.7) will require:
  • Upgrading the tables by visiting the admin page. (The main change will be to add the field "description" to the set and user_set tables.)
  • Updating the library collection webwork-open-problem-library
  • Running webwork2/bin/OPL-update to update the library tables.
  • To use these instructions your server will require at least perl version 5.10.x (5.12.x would be better, 5.18 is the current version) to run weBWorK release/2.7. Type perl --version on the command line of your server to check.

What's new?

At the moment this is in no particular order.


  • level search capability added to LibraryBrowser
  • Add requirement for JSON.pm (for sage)
  • Add requirement for HTML::Scrubber (to for anti XSS fixes)
  • OPL is now default library for sure
  • Remove old methods of displaying math
    • Should ascii math be retained?
    • Should LatexMathML be retained?
    • Should jsMath be retained?
  • WEBWORK_DIRECTORY is insured to be defined in WeBWorK::Constants.
  • numOfAttempts should now give the expected results in homework sets. (Gatewayquizzes need more testing.)
  • OPL-update improvements
    • OPL taxonomy also stored in json file.
  • Datepicker (calendars) in Homeworksets1 & 2
  • Math4 theme updates. (Goehle and Hsu)
  • More like this tag in OPL
  • js directory reorganization
    • this should be reviewed for more tweaking
  • MathAchievement upgrades -- "potions" -- allow for perks for doing well on homework.
    • (requires database upgrade?)
    • Add tabs to Achievement editor.
  • MathJax configured to provide better accessibility. Configured now only defaults.config.
  • Cosign.pm -- fix typos
  • Fixed glitch in Statistics graph
  • Massive amount of tweaks to make the basic WeBWorK CMS interface validate to W3 standards. Problems will usually not validate, mainly because of the use of $PAR which is not a container.
  • Tweaks to update course page -- slightly less scary error messages. -- adding harmless: in front of the message helps but we should change the color on these.
  • Instructors can choose to show paths on hardcopy.
  • Chinese and Korean translations added.
  • Add homework set descriptions as well as file names -- helps keep file names short. (requires database upgrade?)

What could possibly go wrong?

  • The warning messages (labeled harmless: .... ) indicate that many older courses have an extra field named published. This field was replaced by the field "visible" and has not been used for some time. In a future version of WeBWorK this field will be automatically removed, but we leave it in place for the moment for those rare cases where there is important data in the field.
