The monthly Drupal core bug fix release window is scheduled for this Wednesday. However, the last bug fix release was a month ago, and there haven't been enough changes to the development version since then to warrant a new release.

Upcoming release windows include:

• Wednesday, December 17 (security release window)
• Wednesday, January 7 (bug fix release window)

For more information on Drupal core release windows, see the documentation on release timing and security releases, and the discussion that led to this policy being implemented.
