The Drupal Security Team will be coordinating a security release for Drupal 8 this week on Wednesday, August 1, 2018. (We are issuing this PSA in advance because the in the regular security release window schedule [1], August 1 would not typically be a core security window.)
The Drupal 8 core release will be made between noon and 3pm EDT. It is rated as moderately critical. The core release will be an update to a vendor library only.
August 1 also remains a normal security release window for contributed projects.
