This week's edition also includes these inner pages:

Brief items: Brief news items from throughout the community.
Announcements: Newsletters, conferences, security updates, patches, and more.

Note that November 28 is the Thanksgiving holiday in the United States. As is our tradition, there will be no LWN Weekly Edition that day; we will all be too busy eating to put one together. We will keep the lights on over the break and post the occasional article, and we'll be back to normal service with the December 5 Edition.

Please enjoy this week's edition, and, as always, thank you for supporting LWN.net.
