v1.0.1.0

1.0.1.0 - 06-Apr-2026

• New feature: Created a Windows Installer MSI package thanks to Advanced Installer.
• Install automatically provisions PATH environment variable, so you can run ipconfig2 directly via terminal or CMD prompt without requiring app path/directoy. Simply type ipconfig2. You will need to re-open Terminal/CMD for environment veriable to take into effect. Automatic removal during uninstallation for sanitisation.
• Code optimisation: Omitted Get-SystemType redundant function from within threaded function Get-LocalNicIpData, as I can now parse $NetworkAdapterConfiguration from the main script function to $nicJob multithread scriptblock by using comma array -ArgumentList (,$NetworkAdapterConfiguration). Improved memory efficiency and performance.
• Various other bugfixes including omitting unnecessary params from $allInfo = Get-AllSystemInfo call.
• To do: Parse $NetConnectionQuery = Get-NetConnectionProfile from Get-Metadata to $nicJob without corrupting other args/params. This should optimise memory efficieny even further. Not a priority.

v1.0.0.0

1.0.0.0 - 05-Apr-2026

• This release now completes version 1.0.0.0, as all definitions of done are now fulfilled. IPConfig2 now supports most of the data points as native ipconfig2, plus more.
• New feature: Save to file! It can now export the report as a TXT file using the /outfile switch.
• Overall performance optimisation thanks major code refactorisation including multithreads, memory param/return functions. Uses ~50% less memory than v0.5.0.6. Runs ~50% quicker.
• Major code refactor and optimisation: Deprecated all Write-Host commands, superseding it with memory using $output array. Output is now controlled and parsed using in memory by using params and return vars. This improves efficiency and is the approach for standardisation.
• Major code refactor and optimisation: Created new function called Invoke-SaveFile. Using this for save file operation. Now supports folder creation if directory does not exist. Also falls back to a default path of "$env:windir\Logs\ipconfig2".
• Major code refactor and optimisation: Enabled multithreading for big function Get-LocalNicIpData using $nicjob Start-Job. This should improve performance.
• Resolved $NetworkAdapterConfiguration parse error in $nicjob.
• ipconfig2 now detects if system support CIM, else falls back on WMI. This improves OS compatibility and robustness. Refactored in Get-AllSystemInfo function.
• Optimised memory efficieny even more by reducing class reference to Win32_NetworkAdapterConfiguration (retained a seperate instance in Get-LocalNICIpData function due to performance multithreading). Achieved this by calling the class only a single instance in Get-AllSystemInfo, and parsing in memory using return/param functions.
• Significantly improved /release and /renew functions. No more nested loops. Reporting accurately. Using memory where possible. With CIM and WMI fallback for legacy support.
• Due to a catch-22 situation, requiring metadata -> release/renew -> Get-LocalNic Ip data function and multithreading flow, I needed to seperate CIM/WMI system calls outside of the Get-Metadata function.
• Created a new function called Get-SystemType which detects if OS supports CIM/WMI. Then makes single call to class Win32_NetworkAdapterConfiguration. Memory efficiency.
• Appended necessary $args and validation logic to ensure /outfile successfully saves to custom path, and default environment log directory. Error and exception handling now in place as guardrails.
• Fixed a rare glitch where the Interface description would output redundantly during ipconfig2 /release. Now checking IPv4 and IPv6 duplicates correctly, even if no IP address exists or is obtaining DHCP.
• Omitted ipconfig2 /release, sleep-timer as a workaround solution, now that the root-cause is remediated.
• Supports both /resetwinsock and /winsockreset switches for the same function, as a typo fallback.
• Removed colourisation, due to $output memory replacing write-host. More streamline.
• Fixed a bug where /flushdns, /release, /renew, /resetwinsock functions were executing twice due to redundant calls in main args and Display-Output function. This has improved performance and resolved other cosmetic issues.
• Fixed a bug with nested loops within /release and /renew commands. Improved speed.
• Resolved DHCP /release /renew function output accuracy, now reporting correct interface(s), service and timestamps.
• DHCP Renew now only scoped to IPEnabled interfaces for speed.
• Now parsing $metadata out from Display-Output function as return var. Using this in other functions as params such as Invoke-SaveFile. Better memory optimisation, less system calls.
• Improved WiFi output; Now filtering for WiFi profile using $WifiProfileName and $netProfileType vars in Get-Metadata function.
• Fixed bug where IP output table contained stale entries post-release/renew commands. Resolved by re-ordering args switches in Dislay-Output function.
• Additional checks in output for WiFi connected vs disconnected to display last known ssid/key.
• Various other bugfixes and improvements.
• Bug: Wi-Fi output can be inaccurate if you release/renew WiFi NIC DHCP, but will report correctly after reconnection to SSID.

v0.5.0.5

0.5.0.5 - 03-Apr-2026

• Hotfix cosmetic.
• Code optimisation; Complete code is now in modular functions, except for Args and Calls.
• Fixed Netbios over tcpip data point. Now reporting correctly.
• Fixed primary dns suffix and dns suffix search list data points. Now reporting correctly, and applied methods to removed empty array values.
• Fixed wifi ssid/key reporting accuracy. Was previously broken due to null var $netProfileName, which I have now parsed into Get-LocalNicIpData using $netProfileName = (Get-AllSystemInfo).Metadata.NetProfileName.
• New /all switch using $showAll var bool flag, to display extended information including DHCP, DNS, Public ISP, disconected interfaces, and more.
• Default output is now succinct.

v0.5.0.4

0.5.0.4 - 02-Apr-2026

• New /flushdns function. Will report on total stale DNS cache entries and clear in one go.
• New /resetwinsock function. Resets the Winsock catalog to a clean state. Handy feature.
• Replaced static variables with $null and $LASTEXITCODE for propert exception handling in /release and /renew functions. Useful for exception handling when using cmd such as netsh.
• Bug fix reporting and fault-tolerance for /release and /renew functions. Now with CIM and WMI fallback properly detecting success/failure exceptions and fault tolerance between both methods. Preferring modern CIM first.
• New timestamp feature, now reports on operations.
• Various fixes and tweaks.

v0.5.0.3

0.5.0.3 - 01-Apr-2026

• Changed the conditions for displaying received/sent bytes to if greater than zero, rather than if media state is connected. Useful for observing stats retrospectively on disconnected interfaces.
• This also fixes output for missing data point interfaces such as Bluetooth that do not have this telemetry yet.

v0.5.0.2

0.5.0.2 - 01-Apr-2026

• Improved DHCP release/renew functions to use modern CimInstance methods. Retained classic WMIObject methods as a fallback using try/catch blocks.
• Improved output table even more. Now more efficient and consistent with less foreach loops.
• More output now visible irrespective to media state, such as physical MAC address, dhcp, and more.
• Improved metadata table which now dynamically displays multiple network profiles where available.
• Slight formatting tweaks.

v0.5.0.1

0.5.0.1 - 01-Apr-2026

0.5.0.0 - 01-Apr-2026

• April Fool's Day major update, this release is no joke!
• New feature: ipconfig2 /release switch to release DHCP leases on local system. Factored in new function called Invoke-IPConfigRelease. This is independent from Windows native ipconfig and a viable fallback feature.
• New feature: ipconfig2 /renew switch to renew DHCP IP addresses on local system. Factored in new function called Invoke-IPConfigRenew. This is independent from Windows native ipconfig and a viable fallback feature.
• Now supporting NICs with multiple IP addresses! This was not working previously due to output syntax.
• Now displays hidden DHCP 169.254 addresses.
