Among the items that Dan talks about for the NetworkManager 0.9.2 release is auto-unlocking of GSM modems support for libnl/libnl3, better IPv6 handling, translated country names in the mobile broadband provider wizard, VPN details from the connection information dialog, enhancements for the CLI version of NetworkManager, radio frequency kill fixes for ASUS EEee PCs, GObject introspection updates, better cooperation with unmanage devices, and much more. There's also an assortment of fixes to this utility common to the GNOME desktop for managing wired, wireless, and broadband network connections.
Piling up for NetowrkManager is also more exciting changes, or as Dan says, "a Smörgåsbord of Freaking Awesome." Among the changes queued up for this next NetworkManager release is using nl80211 for talking to kernel drivers rather than WEXT, uncoupling of IPv4 and IPv6 addressing, and bonding support. Work on VLANs and network bridges is also being worked on and may make the cut for v0.9.4. NetworkManager 0.9.4 is also likely to offer better firewall interaction and connectivity detection.
