Fixed from version 2.08: Some filters stopped working...
Version 2.08
Says support for filtering process ID (in advanced filters
window), for example:
Includes: Process: 327
Version 2.07
Fixed automatic refresh flickering issue.
Version 2.06:
Fixed issue: Opening properties dialog boxes and other windows on the wrong monitor on multi-monitor systems.
Version 2.05:
Added support for GEOLITE database uptown. Now you can download the GEOLITE city database (GeoLiteCity.dat.gz), put it in the same folder as cports.exe, and CurrPorts will automatically use it to get the country/city information for each remote IP address.
Version 2.02:
CurrPorts displays a simple error message if closing one or more TCP connections fails.
Version 2.01:
The "Remote Address" and "Local Address" columns are now sorted numerically by IP address. (In previous versions, they were sorted alphabetically)
Version 2.00:
Adds an optional fifth argument/off command line option, which allows you to specify the process name (example: Firefox)
Version 1.97:
The "Use DNS cache hostname" option is now turned off by default as it seems that reading the DNS cache causes a memory leak on some Windows 7/x64 systems.
