We added the ability to generate images and files via R via the sw_R() function!

Generating files, like CSV's or Rdata files, is also supported.

When successful, a relative URL will be returned with the name of the file in the key. See the manual section "Create via R" for examples:

We now allow delimiters for inline PHP evaluation in feedback rules with the ~ as a delimiter.

We added exercise solution to the advanced search.

We added an option to hide solutions via the class settings.

We added an option to add notes during practice via the class settings.

We removed similar-looking characters from access codes to avoid confusion.

We added a message for the student that results will not be saved when the class end date has passed for the student.

We changed the GeoGebra exercise type so that the SWCHECKEQUAL variable is no longer displayed because it's now auxiliary.

We fixed a bug where restoring a feedback template with variables does not work.

We now also save the author as the creator of an exercise when the author starts with the creation using a template.

We made improvements on the manage teacher page.
