The latest MultiPing release improves performance (it's reasonable to always sort now), tweaks the GUI a bit, and contains a handful of miscellaneous fixes based on user requests. Customers on active maintenance can update to the new version for no charge, and more information is available on the release notes page. Downloads are available in the account system and multiping.com.
In other news, we've ventured into uncharted territory. The App Store is currently reviewing PingPlotter Mobile. We aren't sure how long the process will take, but we're eagerly awaiting approval and plan on releasing as soon as possible.
