The latest release of Simon is version 5.1.1.

• Added a Ping test plug-in, that supports sending a variable number of packets, and can count the ping as a failure if the response time or packet loss are over configurable limits.
• Added a DNS test plug-in, to check that a domain name can be found — any kind of server. Doesn't prove the server is actually up, but just that the computer knows where it is.
• Added an Application test plug-in, that checks that an application is present, and optionally that it is currently running. If it isn't running, you can use a Launch notifier to re-start it automatically. The Smart Change Detection feature can be used to detect upgrades or other alterations, and the Visit Site function can be used to switch to (or launch) the application manually.
• Completed migrating the existing test types to the new plug-in architecture. There have been several behind-the-scenes changes, so let us know if you notice any problems.
• Changed the Notifiers selection section of the Add/Alter Test sheet to use an expanding list like the new Automatically Pause Test feature, for consistency and a better user experience.
• Added Restore Factory Settings buttons to the remaining preference panes.
• Fixed a bug where the data files could grow rather large, due to old log entries not being deleted.
• Fixed a minor issue with the Speech notifier plug-in.
• Now doesn't report a false failure when the computer is put into sleep mode during a check.

• Added a flexible Automatically Pause Test feature to the Add/Alter Test sheet, that allows suspending a test on any combination of days and times, e.g. if the server is restarted at 03:00 every day and offline for maintenance on Sundays from 10:00 to 12:00.
• Added a Restore Factory Settings button to the Updates preferences pane, that changes the preferences in this pane back to the recommended values. Also corrected tabbing for people with full keyboard access enabled.

• Rearranged the Add/Alter Test sheet to group the various sections under disclosure triangles, so people with smaller screens can hide bits they aren't interested in. The disclosure states are remembered for next time.
• Improved the implementation of the plug-in architecture.
• Added a plug-in architecture for test types.
• Migrated the two existing test types to a plug-in. Other test types will be added in a later beta of 1.2.
• Started work on an Automatically Pause Test feature.
• Updated the engine for the E-mail notifier (the Pantomime framework) to the latest version.
• Made a number of minor improvements to the handling of links to various pages on the Dejal site throughout the app.
• The Help ▸ Dejal Orders menu item and the Buy... button in the Licenses window now display the Dejal Orders page with the appropriate application already selected.
• Some behind-the-scenes improvements to increase efficiency of the main application controller.
