• Fix: Sentry-go Plus! HTML Content Monitoring Component (v5.1)
  Fix: Sentry-go Quick IIS Web Monitoring Package
   
  In both the above components/monitors, if monitoring the time it takes to load an entire web page has been selected, the component could fail to access the correct image URL, especially when using HTTPS. This in turn, could lead to a excessive delay before the check completed. In addition, no alert would be triggered if any image URLs could ot be accessed or were not found.
   
  Both of these issues have now been corrected.
    
• Fix: Sentry-go Plus! Network Monitoring Component (v5.1)
   
  If running on a non-English verson of Windows, the network monitoring component would not detect or trigger an alert even if connectivity was lost. This fault has now been corrected.

  Enhancement: Sentry-go Quick File Monitoring Package
   
  A new check has been added that allows modifications (new files, file deletions & updates) to files within a directory to be configured as a single task. Previously, three independent checks would need to be configured for this.

• New! Sentry-go Plus! v2.0
   
  Sentry-go Plus! v2.0 includes a number of significant enhancements to aid monitoring, configuration & reporting ...
   
  - New file monitoring features.
    
    - Automatically track details of users who access or change files, or perform file operations etc.
    - New "file accessed" & "directory accessed" monitoring checks allow youi to see who's
      accessing the file system, and when.
    - Updated configuration interface, allows defining and refining your monitoring check even easier!
    - New web reports provide access to the new features.
   
  - Enhance or upsize your solution with the new Scripting monitor.
   
    This new monitoring component allows custom commands, files & scripts to be run & monitored
    by Sentry-go Plus! just like any other component. Results are then analysed automatically and
    resposnes/alerts triggered as required. This is the ultimate in customisation, allowing you to
    plug-in your own monitoring whilst benefiting from the management, response, alerting &
    reporting built-in to the Sentry-go Plus! framework. Ideal for more specific monitoring tasks, or
    when upsizing an exsiting script-based monitoring solution.
    
  - New Scripting Wizard.
   
    - A new version of the Sentry-go Scripting Wizard is included in this release. Built on the original
      idea of allowing scripts to be generated without the need for any coding, this version allows both
      alerting & monitoring scripts to be created in a user-friendly way - again, without requiring you to
      write a line of code!
    - Choose from a number of templates to generate your script.
    - A new API also allows developers to create their own templates which can then be shared with
      others.
    - A host of new monitoring scripts have been added to the on-line scripting library, to support
      the new Wizard.
   
  - New Sentry-go Plus! Client Console features.
  
    - Now allows many configuration options to be verified both before saving & from within the
      monitor itself (via web reporting).
    - Integrates with the new Console Browser.
   
  - A new Console Browser integrates with standard web reports from within the Client Console.
   
  - An updated Setup Wizard allows for quicker installation, now with the option of automatic installs.
   
  In addition, the following corrections have been made in this release ...
   
  - The integrated web server no longer hangs when incomplete requests have been made.
  - Delayed e-mails are no longer saved if the associated options are disabled.
  - Delayed e-mails are now restricted in number to prevent a backlog building up.
  - The monitoring scheduler has been updated to correct issues that could arise if a combination of
    schedules were specified for the same checks.
   
• Updated Sentry-go.com
   
  The web site's been enhanced for Sentry-go Plus! v2.0, a new & improved Scripting Library and now includes built-in search for both web content and documentation.
   

• Fix: Sentry-go Plus! Setup Wizard (1.2.2)
    
  In some cases, multiple selections could be made when choosing which install type to run, even though only one option was valid. This has been fixed.
    
• Fix: Sentry-go Plus! Client Console (1.4.1)
    
  When a generated script containing a long filename was used, the script would be empty when "Edit" was selected, after successfully running the Scripting Wizard. Long filenames are now correctly handled between the Client Console and the Scripting Wizard.
   
• Fix: Sentry-go Plus! (1.3.1)
   
  - Under some conditions, the monitoring scheduler disabled monitoring tasks if the default time
     interval was set to zero, even if the tasks themselves had overridden (scheduled) times. This
     has been corrected.
  - Non-system alerts could be triggered even if they were disabled, if the alert group was not valid for
     the alert being triggered.
  - When sending an authenticated e-mail alert, the e-mail could fail with a VBScript compilation
    error. This has been corrected.

  - If a response or alert script is run using a named logon, the logon information
    supplied can now be verified from within the Client Console.

    remote directory access can now be verified from within the Client Console.
   
• Enhancement: Sentry-go Plus!, Client Console & Setup Wizard (1.2.1)
    
  Alerted users, as well as alert files & scripts can now be defined as accepting "system & config. messages". When this option is enabled, these alerts will also be triggered in the event configuration or other internal errors occur, causing the monitor's activity to be affected. For example, dial-up networking or web publshing errors.
   
• Enhancement: Sentry-go Plus! Client Console (1.2)
    
  - New "Test" buttons enable connectivity checks (e.g. network, database, mailbox etc.)
    to be performed from within the Configuration in order to verify checks from the Client.

• Fix: Sentry-go Plus! (1.2)

• Fix: Sentry-go Plus! Client Console (1.2)
    
  When minor edits were made to the configuration, the Console could, under some circumstances fail to update the configuration file time, meaning that the server would fail to note changes until it was manually restarted (or other configuration options were changed). This has now been resolved.
      
• Fix: Sentry-go Plus! Sentry-go Plus! HTML Content monitoring component (1.2)
    
  When checking "date modified", the monitor would return an error indicating that the header value was not available, in under some conditions when it was. This has now been corrected.

  Authenticated SMTP e-amil alerts can now be sent in addition to standard ones, without the need to create a custom e-mail.
   
• Fix: Sentry-go Plus! Alerting (1.1.2)
    
  When an alert was raised, which in turn caused an alert file or script to be called, the monitor could fail if parameters were not entered and/or an alternate user was defined to run the job.
   
  If the "Test" button was used to verify an alert script, the initial web report would be displayed, but thereafter a 404 (not found) error was returned.
   
  Both of these faults have now been corrected.
   
• Fix: Sentry-go Plus! (1.1.1)
    
  Under some conditions & especially after installation/reinstallation, the monitoring service could fail in module goQMINET.DLL. Restarting the service would resolve the problem. This has now been corrected.

  Under some conditions, the licence key generated for the shareware version of Sentry-go Plus! would expire after only one day instead of the 21 day evaluation period. This has now been corrected; shareware licences as well as standard evaluation licences will expire after 21 days.
   
• Enhancement: Sentry-go Plus! E-mail Send/Receive monitoring component (1.1) 
   
  E-mail Send/Receive monitoring can now use authenticated e-mails as the verification method in addition to standard (non-authenticated) SMTP mails.   
   
• Enhancement: Sentry-go Plus! Client Console (1.1)
   
  The Client Console now allows easier registration of monitors, including the ability to quickly register multiple monitors at once.
   
• Enhancement: Sentry-go Plus! Network monitoring component (1.1)
   
  When an error is reported, the nature of the error is now appended to the message. Thios indicates why the check failed. Previously, only a generic error was provided.
   
• FIX: Sentry-go Plus! Network monitoring component (1.1)
   
  When automatically scanning for network resources, the Current Status report indicates
  "[Not Yet Run]" even though checks had been performed. This has now been corrected.

  The HTML Content monitor now allows you to both POST data & send parameters to a web page when verifying results.
   
• FIX: Sentry-go Plus! HTML Content monitoring component (1.1)

• FIX: Sentry-go Plus! HTML Content monitoring component (1.1)
