# Form letter - net-next is closed

The merge window for v6.3 has begun and therefore net-next is closed
for new drivers, features, code refactoring and optimizations.
We are currently accepting bug fixes only.

Please repost when net-next reopens after Mar 6th.

RFC patches sent for review only are obviously welcome at any time.
