Changelog

Most of the changes in this release are under the hood. Code has been refactored to make way for future enhancements. Please let me know if you encounter any bugs.

Here are the visible changes:

    The project now targets .NET 4.5. It previously targeted .NET 4.0.
    New DNS probe! In the hostname box, type 'D/name_or_ip' and it will perform a DNS lookup. This feature is fairly hidden at the moment, but will become more apparent in a future release. Additional probe types are planned.
    Renamed 'Change Log' to 'Status History'.
    Most dialog boxes have been converted to custom dialog boxes.
    Added an error icon to custom dialog boxes when displaying error-type messages.
    Options -> Advanced -> Don't fragment: This control is now a checkbox and it now includes an information popup that explains the option.
    Don't fragment option now defaults to off.
    The generic background logo in each probe window no longer re-appears after stopping a probe.

Changelog

New traceroute probe! In the hostname box, type 'T/name_or_ip' and it'll perform a traceroute right in a probe window. This feature will become more apparent in a future release, and additional probe types are planned. Eventually, the old separate traceroute window will go away.
New option to log status changes to a text file. This option only writes to the log when a host goes down or up. The output is in a tab delimited format that is suitable for Excel or database imports. Note: vmPing does not lock the file, so logging will fail if the file is opened by Excel and vmPing tries to write to the file.
Fix for vmPing no longer reading hostnames from the command line.
New command line option to specify a file containing a list of hostnames. One host per line. The file is read at startup and vmPing immediately begins pinging each host. Remember to use quotes if your file path contains spaces. Usage: 'vmPing.exe <path_to_file>'
Darkened the default color for DNS and traceroute probes. This is not yet customizable.
The control bar that appears when you hover over a probe window is now darker (50% black with 50% transparency). The icons are now darker and the highlight style was changed to accommodate the new colors.
Re-styled the custom dialog window so it's wider and uses a smaller font.
Extra tooltips explaining the options under Options -> Log Output.
