Upgrade Instructions

• Many third pardy javascript libraries are no longer packaged with WeBWorK. The recommended approach is to install via npm:

1. Install npm from your package manager (Ubuntu: apt install npm CentOS/RHEL: yum install npm).
2. Use npm to install third party javascript:

  > cd /opt/webwork/webwork2/htdocs
  > npm install

• WW 2.16 requires MathJax v3. Previous versions of WW required MathJax v2, so if you are upgrading an existing WW installation you will need to switch to MathJax v3:

  > cd /opt/webwork/MathJax
  > git checkout origin/master

• The following perl packages will need to be installed
  • HTTP::Async (on Ubuntu install the package libhttp-async-perl)
  • CGI::Cookie (see https://github.com/openwebwork/webwork2/pull/1149)
• There have been some tweaks to localOverrides.conf.dist. If you have not done any customization to localOverrides.conf then you should consider replacing it with a new copy of localOverrides.conf.dist. If you have made customizations in localOverrides.conf, you should consider synchronizing them with the latest version of localOverrides.conf.dist.
• WeBWorK is currently not compatible with recent versions of the SQL::Abstract package, so avoid upgrading past version 1.8. WW is known to work with versions up to 1.87.

Call for Translators

Some text has changed in the WeBWorK interface, so there are new entries that need to be translated into other languages.
