    • The remote agent now uses the latest sample instead of sometimes using an older cached one.
    • Improvements to long-term memory use that was causing an array index error (and other memory / sluggishness problems)
    • Importing a .PP2 sample set would sometimes give a licensing error instead of opening.

    • Fixed an issue where Local Network Discovery wouldn't let you export to CSV.
    • On MacOS, fixed an issue where new targets always showed 2.5 second default trace intervals - now it uses the last setting, or what's in the summary you launch a target from.
    • A good handful of unexpected errors (object references, contract missing and similar) were corrected.

    PingPlotter 5.5.2 - September 13, 2017

    • Two new features are available in this release.
      • Local Network Discovery - You can now scan your local network using a wide variety of protocols to identify devices that can be affecting your network performance. You will love how easy it is to view your network and select devices to monitor with PingPlotter. Local network discover is available in Standard and Professional editions.
      • Dynamic DNS Support - Do you use PingPlotter to monitor a server that doesn't stay on a fixed IP address? Now PingPlotter will follow DNS changes that point to the system and keep monitoring it regardless of IP address changes. Instructions on how to use dynamic DNS are available in the manual.
    • New features aren't the only thing to get excited about. This is the first simultaneous release of macOS and Windows. Hooray for cross-platform technology!
    • Fixed a bug that caused some new traces to start at the wrong default trace interval.
    • Improved startup performance for users with larger data sets.
    • Hunted down and tackled a bug that produced "route 0 no found" errors.

    • The Professional edition for macOS now includes a web interface for viewing PingPlotter activity remotely.
    • Professional users can also view Jitter graphs conveniently located above timeline graphs.
    • Want more packet types? You got it! Support for UDP and Remote Agent packets are at you fingertips. TCP packets did not make it due to some challenges with OSX libpcap generator (sorry, we're still working on this).
    • More robust handling of network interface changes (up/down/left/right/etc).
    • Changing license modes now restarts application and service together.
    • We made PingPlotter better at detecting and handling upgrades when running as a service.
    • Since everybody loves spinning circles... We added a "progress spinner" when uploading image to
    • Improved trace interval performance when running as a service.
    • Improvements to CPU usage, especially on macOS Sierra. Welcome to the family Sierra!
    • Then we just threw in a bunch of other fixes and improvements to core data collection and display. We call it "polish."

    5.0.2 Beta - Sept 30, 2016

    • Made a small but important change so users upgrading from previous versions won't run into a wall when one of their settings doesn't transfer correctly.
    • Fixed a problem that blocked PingPlotter from starting for certain users upgrading from version 1.4 when their configuration information was not in the expected format.
    • Fixed an issue that prevented PingPlotter from launching on systems running OS X 10.10.

    5.0.0 Beta - Sept 15, 2016

    When we released the Mac Preview late last year (2015), we loved it, but knew it had a long way to go to make it comparable to our Windows version. We've made huge strides towards that with the just-released PingPlotter Beta for macOS. It's had a lot of internal testing, and we think it's great. We are eager for your feedback, especially if you run in to bugs or unexpected errors.

    PingPlotter Beta for macOS shares an "engine" with PingPlotter for Windows. The alerts system, settings system, summary graphs, statistics calculations, auto-save, share and more have all been injected into the Mac version. The user interface, however, is all Mac. It takes advantage of macOS's native controls, buttery smoothness, and rendering goodness. Running as a service on Mac is also entirely macOS native (and when you invoke the Install Service option from the App menu, it uses native Mac launchctl systems for this). Everyone in our company has a Mac as their main computer. We're certainly enjoying the beta, but we really hope it makes network troubleshooting suck less for you.

    If you've been using Version 1.4 "Preview" released early this year, the only bad news is that your collected/stored data won't automatically migrate to the new version. Export your data before you migrate!

    We're thankful for you - and that you're using our tool(s) to help with your network troubleshooting.
