We have reached the end of another week, so I hope that you can all have
an enjoyable and relaxing weekend.
As always, there were numerous security vulnerabilities reported and
fixes released.
Of particular note (especially to us in the Education sector) were the
drupal issues (https://www.drupal.org/sa-core-2018-004).

Here’s a summary (including excerpts) of some of the more interesting
