Added:

  • Now checks for an excerpt. If an excerpt exists, that will be the description in the .ics file. If not, the content field is used (and cleaned up).
  • Permalink to the post now passed into the .ics (for iCalendar only—I can't test the others)

Known issues:

  • When using an excerpt for the Description, the Description ends up having no line breaks. I'm not sure why this is.
