Version 1.0.55
*Changed the timeout fro 10 seconds to 12.  Some puzzles that were supposed to work were timing out just short of the packet getting there.
Version 1.0.54
* Minor changefor developers allowing more information about what is happening during regression testing. 
Version 1.0.53
* Show a line between devices when dragging ethernet cables.  Makes it easier to see.
* Tried highlighting what you are supposed to be filling out next, when creating network links.
Version 1.0.52
* Change publish URL to an actual domain.
Version 1.0.51
* Added small time-based delay when printing packets; on fast computers the packets would fly by too fast.
Version 1.0.50
* Added regression testing for making sure we do not break things while making changes to the UI or how the system works.
* Added regression tests for most all the networks
* Able to change gateway if the primary network connection does not have DHCP.  There was an issue with a puzzle because of this.
* Do not check firewall rules if the firewall checkmark is turned off.  You can disable the firewall rules by turning off the firewall.
* Get the reload button working properly.  You can reload a puzzle and it will reset to its original state.
* Better listing of puzzles and highlighting the next puzzle to do.
* When resetting a switch, reset the vlans on that switch.  Somewhere this broke and we needed to put it back.
* Added some action debugging.  No impact on users, just developers.
* Better processing of wireless link autojoin
Version 1.0.49
* Change level1_practice5.  It had been a puzzle with two DHCP servers, but we have not taught that concept yet.  I change it so the DHCP server was passing out bad DHCP.  IPs already exist.
* Fixed a few bugs in other “practice” levels.
* Made a test for a network loop.  So we can have a “ping without looping” test.  So we need to have a successful ping that does not cause a network loop.
* Fixed an issue with wireless bridges.  They were routing packets instead of forwarding packets, which broke them in a few instances.
* Make it so a NIC can spray.  It creates bad packets that just keep coming.
* Fix some issues with wireless links.  Some puzzles had saved multiple wireless links to the same device, which ended up having some rather bizarre issues.  Since all wireless links are rebuilt on load, I made it so none of the wireless links are saved, and if they are loaded, they are discarded.  It solved a number of issues. 
Version 1.0.48
* Fix a traversal class not serializable error
* Close the file -> load toolstrip menu after a load.  It had remained annoyingly open.
* Added a bunch of “practice” puzzles.  These are for practicing troubleshooting.  They do not give you a lot of information about what the problem is; you need to do a bit more testing and trying things to figure them out.
* Added a bunch of level5 practice puzzles.  More physical networking and wireless than routing issues.
* Added the solved versions of the office networks.  One with wireless linking between them, and the other having physical wires.
Version 1.0.47
* YAY! The long-awaited ctrl-z / ctrl-y works.  Undo / redo.
* Lock a device to a location
* Add a tree.  Wireless packets cannot go through a tree.
* Add background shapes.  So we can draw a building and have understandable line of sight.
* Add a wireless line of sight puzzle.
* Went through old puzzles and locked some items in their locations.  Makes some puzzles need to be solved the way the puzzle was intended to be solved.
Version 1.0.46
* Added a frozen device.  Fix it with a reboot.  (power off / power on)
* Added a bad power-supply (device catches fire when powered on.  Need to replace the device to fix)
* Added bad electricity. (device continues to catch fire, even after being replaced, until a UPS is added)
* Can right-click a network wire.  Delete, edit, replace.
* Added frozen device, bad power-supply and Needs UPS as ways to randomly break networks.
* Optimize the redrawing of the screen packets.  Speeded it up considerably
* Add puzzles for frozen device, bad power-supply, and needs a UPS.
Version 1.0.45

Version 1.0.43
* Added the title to the translation window.  Puzzle titles can now be translated.
* Use the translated titles for the puzzle names on the puzzle selection box
Version 1.0.42
* Fixed some bugs with working in French – puzzles would not show
* Fixed bug in French – “Ping to” would not work
* Added a translation box when working on puzzles.  Ctrl-click the network message in the options window to pull up a translation box.  Look at two languages simultaneously.  Has save button to save your changes from there.
Version 1.0.41
* Have the ability to randomly break a network.  If you want to just test your brain for fun, or if you are a teacher and just want to generate some homework of some sort.  This can help.
* Added another solved network (InternetHomeAndOffice)
* Give us more options for viewing text under devices.  This lets us see things much more cleanly.
* Allow different captioning systems.  Hostname only, IP only, host + IP, none, full
* firewall rules can now affect VPN traffic.  You can block from a VPN to the office VLAN, for example.  Also, can block guest VLAN from pinging something across the VPN.
Version 1.0.40
* Jumping ahead version numbers.  Adding Educational Mode (see doc on the wiki for a description of the basic functionality added) https://git.solidcharity.com/timy/EduNetworkBuilder/wikis/Teacherdoc
* Added the ability to make msi files for better deployment in multi-user settings
* Adjusted drag functionality so we do not jostle devices around accidentally
* Fixed bug when trying to ping wireless devices by name
* Fixed a bug pinging 0.0.0.0
* Fixed lots of other bugs
Version 1.0.33
* Fixed a major bug in settings that would blow up new installs.
* ctrl-right-click a device to add “hide” to the context menu.
* From the puzzle menu you can ctrl-alt click items to mark them as solved.
* Display bad subnet masks (that cannot be displayed using CIDR notation) as /?
* Allow pings from devices that are locked.  A bug made it so we could not change the address we wanted to ping to; all ip-addresses were locked, even a “ping to” address.
* Minor bug: If we ping a local IP that does not exist, the error message we were getting was the wrong error message.  Fixed that.
* When wireless device is powered off, remove all wireless links.  Links connected to WLAN had been reconnected.  Fixed that.
* Cannot go into the network options if we have loaded the network from resources.  This way we cannot “cheat” by changing the network options.  This is in preparation for setting this up for school use.  Making it harder for students to cheat on homework assignments.
Version 1.0.32
* Allow dragging of items
* Select multiple items for dragging by using a nice big drag-box.
* Highlight the multiple items if selecting them

* Cannot edit something that is powered off.  Also, cannot ping, do DHCP refresh, etc.
* Fixed losing the VPN password changes when editing VPN Info.
* Fixed anchoring of puzzle filter box.
* Added invisible items.  Forgotten switches and unseen network wires.  Right now, the only way to make something hidden is by editing the file and saying <invisible>true</invisible> on it.
Version 1.0.31
* Added powering off switches, routers, and the like
* Added traceroute
* Added a few puzzles for those

* Fixed the VPNify puzzle.  Had a goof in it.

* Added an infrastructure for Puzzles (needs work)
