Improved Packet Simulation, Middleboxes, Router-on-a-Stick and More!

Greetings fellow Tower Admins,

We're pleased to bring you the latest major update (build 0.10.9), featuring improved packet simulation, middleboxes, router-on-a-stick, and more!

Improved Packet Simulation: Network loops cause broadcast storms, and packets are visible in real-time. You can now use STP commands to prevent storms and track down loops.

Router-on-a-Stick (Port Subinterfaces) Routers now support port subinterfaces!

Middleboxes: New [c]middlebox[/c] commands and the [c]mbox[/c] program.

Power Socket Editing: The Socketeer tool can now add and remove power sockets

(Note: power socket removal is not supported on existing saves before 0.10.6)

Save System Improvements: Autosave is now on an adjustable timer, and the save menu has been reorganized with folder-based saves for easier management.

Various QoL & Bug Fixes: Include fixes across STP, RIP, DHCP, DNS, co-op sync, and more.

Full Changelogs (0.10.0 - 0.10.9):

New:

• new: re-implemented graph traversal with actual packet simulation (network loops now possible).

• new: requests now has latencies proportional to number of hops.

• Addednewadded "net port" sub command (allows port metrics/costs, custom load balancing configuration).
• Addednewadded port subinterfaces (used with vlan command for inter-vlan routing).
