Description: 
The upcoming Drupal core security release window [1] has been rescheduled
from November 19, 2025 to November 12, 2025. As normal, the window will occur
between 1600 UTC and 2200 UTC.

.... Schedule change for back-to-back DrupalCons

This schedule change is due to DrupalCons Vienna [2] and Nara [3] overlapping
the October and November core security windows. We do not schedule core
security windows during DrupalCons so that site owners and agencies can
attend these conferences without having to worry about their sites or
clients.

December is also not typically used for core security releases due to the
quick sequencing of the Drupal core minor releases and the end-of-year
holidays. This would mean a period of four months where we could not provide
any regularly scheduled security update.

.... No special release procedures

The schedule change is not due to any highly critical issue that would
require special release procedures.

As a reminder, a Drupal core security window does not necessarily mean a
Drupal security release will occur, only that one is possible.
