This firmware is now available via the Nokia Software Updater.
It might not be in place for all regions just yet, I’ll be trying mine tonight or tomorrow so I’ll report back then.

Most interesting features for this release are:
# Flash Lite 3 is included, so Flash video sites will work, including YouTube (just as on the N95 8GB v15 firmware from a couple of months ago)
# The Web runtime is included, meaning that standalone widgets are now possible
# Greater Bluetooth headset compatibility
# Better handling of entering lots of text into web page dialogs
# Speedier Gallery in every way
# Faster Java runtime, so Java apps start faster
