Simon 2.2.1b2
(Release 2028b): released 2007-02-15; requires macOS 10.3.9 or later; Universal Binary
Changed the Web (HTTP) service's plug-in to not record session-only cookies, to avoid issues with servers that get confused with such cookies in a different check (session).
Fixed an issue with the Growl notifier plug-in that prevented it from working properly under Mac OS X 10.3.9.
Simon 2.2.1b1
(Release 2027b): released 2007-02-12; requires macOS 10.3.9 or later; Universal Binary
Fixed an issue that affected some people, particularly those who use Apple Remote Desktop or similar remote control products, where Simon would erroneously display "offline", some icons would disappear, and sometimes other cosmetic issues. This was a tricky one to track down, managed with the kind help of a customer. If anyone still experiences these symptoms with this release, please let me know ASAP.
Improved the reliability of the Script service plug-in, so it doesn't terminate the script before all output has been received.
Fixed an issue with the Specific DNS service plug-in, where it didn't report a failure for some machine configurations.
Added test check overlap prevention. During automatic checking (i.e. not when manually starting a check), if a test is already being checked when another is due, the latter waits till the former is done. The upshot being that only one test will be checked at a time, providing more reliable check times, and avoiding using too many system resources.
Added improved exception logging, to help with diagnosing any future issues.
The Check Now menu items for the Source and non-web Preview windows are now correctly enabled.
