Welcome! If you need to update your Drupal 8 site to the latest feature branch, this post is for you.
Drupal 8.8.0 introduced many exciting changes. On the heels of this release, we also saw a security release for Drupal 8.8.1, which covers four distinct security advisories (SAs). Drupal 8.7.11 also has fixes for those SAs, but developers might consider this a golden opportunity to take care of both updates at once.
