• The default timeout used to determine when a job should be unloaded from the Calculation Server was increased from 10 minutes to 60 minutes.
• A cancel button was added to the Configuration Tool's "Connecting to the Calculation Server" dialog.
• An issue was resolved that caused run consoles to stop displaying additional screen output after pausing and resuming the job.
• An issue was resolved in the Calculation Server that prevented the proper animation of jobs starting at calculation times other than 0.0.
• The user defined constant was modified to update all the components in the model when its default value is changed from the property editor.

Version 0.25.1 - Released 10/8/06:

• An issue was resolved which caused improper multi-edit behavior in  some table editors.
• A view pop-up menu was added to "locked" views containing many of  the items found in the menu of an "unlocked" view. The pop-up menu is  displayed when right-clicking in an empty section of an open view.
• The Job Status UI was updated to include job nodes in the server/ folder tree. In addition, when selecting a job in the tree a job  information panel will be displayed (rather than the job table) that  shows more detailed information about the job.
• An issue was resolved that prevented the proper update of the Job Status display when deleting jobs that were not loaded.
• An issue was resolved in the submit dialog that prevented the  automatic job name generation feature (the checkbox next to job name)  from properly generating a new name.
• The submit dialog was updated to allow calculation type selection for jobs submitted via the jEdit plug-in.
• An issue was resolved in the Calculation Server job loading routines that would cause some previously completed jobs to be flagged  "Running" when loaded.
• The Calculation Server job loading routines were updated to include  the"Loading" status. This status indicates that the job is currently  being read into memory and/or indexed for access by client applications.
• The logic for detecting and reporting incompatible plug-ins was  updated to give a more readable log file message: "This plug-in is  incompatible with your SNAP version: some_plugin.jar"

Version 0.25.0 - Released 9/17/06:

• The SNAP runtime system has undergone a major overhaul:
  • The Calculation Server was updated to include support for multiple Root Folders (with sub-folders) that can contain any number of jobs. These Root Folders can be mounted in Job Status, the Animation plug-in's source run selector or the submit dialog's folder selector by selecting the "Mount Root Folder" item from the right-click pop-up menu of the local Calculation Server node ("localhost"). These folders can be un-mounted by selecting the "Unmount" item from their right-click pop-up menu. Sub-folders can be created by selecting the parent folder and selecting the "Create Folder" item from the right-click pop-up menu.
  • The submit dialog was updated to include remote submission capability and restart job selection capability. In addition, the local restart file selection was updated to allow selecting a local file to submit as the restart file for a remote job.
  • Optional remote connection capability (disabled by default) was added to the SNAP client applications to allow access to remote Calculation Servers for submission of jobs and animation of the results.
  • Jobs managed by the Calculation Server are no longer loaded and processed at startup. Instead, the calculation job files (CJF) that are stored with each job are parsed on-demand and released from memory until needed.
  • Support for sequences of restart jobs was added to the job queue. This allows a sequence of restarts to be submitted before the preceding jobs have started so long as those jobs have been submitted.
  • Note that with this update, existing submitted jobs will not be automatically available as jobs in the Calculation Server. The data files produced under earlier versions of SNAP must be selected directly to be used by animation masks.
• The ModelEditor Java3D support was revised to allow running without Java3D installed. Note however that features that depend on Java3D will not be available.
• The Archive, Database servers have been removed. Support for distributed access control has been moved to the individual Calculation Servers.
• The jEdit SNAP plug-in has been updated. Previous version of the jEdit plug-in are not compatible with this SNAP release.
• The legacy RELAP5 code plug-in has been removed from the distribution along with the TACT and R5UPD feature plug-ins.

Version 0.24.4 - Released 8/14/06:

• An issue was resolved in the user numerics (constant and variable)  drawing that caused the user-specified label to be discarded when changing other properties of the user numeric.
• Undo logic was added to the drawn component "Orientation" property.
• An issue was resolved in the display bean creation for pasting connections into animation views that would cause the resulting line annotation to display more points that the original connection.
• An issue was resolved that would prevent the Preferences dialog from being properly displayed on some systems.
• An issue was resolved that prevented the ModelEditor from properly repainting when switching from "Single Window Mode" to "Multiple Window Mode."
• The Job Status job table repaint logic was optimized to improve performance for Calculation Servers that contain a large number of jobs.

Version 0.24.3 - Released 8/3/06:

• Updated to Jython Version 2.1.
• An issue was resolved that caused the Welcome window to be displayed  when starting the ModelEditor even after selecting the "Do not show this dialog again." checkbox.
• An issue was resolved in the Navigator that could prevent contents of View component nodes from properly updating in some circumstances.
• An issue was resolved in View component that prevented the View from properly redrawing when the "Show Connection Points" property was  changed.
• A "Maximum Log Size" preference was added to the Calculation Server configuration to control how large the log file can become before it is rolled to the next file. Note that a total of 10 files are created and these file names reused as the log is rolled over.
• An issue was resolved in the undo process for deleting components that could cause the process to fail after repeated undo.
• An issue was resolved that prevented the "Terminate Job" feature in the Console dialog and Job Status from updating the job's status to "Completed".

Version 0.24.2 - Released 7/21/06:

• An issue was resolved in the ModelEditor batch interpreter that would cause user defined numeric references from being lost when saving a file in batch mode.
• The Text Annotation resizing logic was updated to more correctly determine the size of the rendered string.
• A Preserve Ratio checkbox was added to the "Scale Drawings" dialog that locks the length and width scale factors to the same value.
• An issue was resolved that could cause a boolean editor (yes/no, true/false, on/off) to continuously redraw itself.
• An issue was resolved in the Animation plug-in that prevented newly added beans from being properly animated without disconnecting and reconnecting the animation.
• An issue was resolved on Windows that would prevent the calculation server from shutting down if any client applications were running.
• The Start Server Automatically preference was added to the Calculation Server section of the configuration tool. When activated, the Start Server Automatically preference will enable the local server to startup when needed by local client applications. When not activated, the user will be prompted to startup the server instead. Client applications are considered local only if they are running on the same computer as the server (referred to as "localhost") and running as the same user as the server.
  
  This property will enable the local server to startup automatically:
  
  • when submitting a job
  • when browsing the local server via Job Status
  • when selecting a run for an animation from the local server
  • when connecting an animation to the local server
  
  Activating the Start Server Automatically preference enables the Server Idle Timeout preference. This is the maximum amount of time (in minutes) that the Calculation Server will stay active while no clients are connected. Specifying 0 for this value will prevent the server from shutting down automatically. Note that the Calculation Server must be restarted for this value to take effect.
  
  
• Remote calculation server connection capability was added. This feature is controlled by the Allow Remote Connections property and defaults to No. Note: This feature is only supported under Java version 1.5 or above.
  
  To allow remote connections from other users, first change Allow Remote Connections property to Yes and restart the calculation server. Then, export the server's public key to a convenient location by selecting the Export Public Key item from the File menu. This key can then be transferred to those users who require access to the server.
  
  To connect remotely to another user's calculation server, first open Job Status. Select the Add Server item from the File menu. Enter the server's host name or IP address in the Server Host Name field and their calculation server port in the Server Port field. Then, select the Server Key File received from the remote user that started the calculation server. After pressing OK, the remote server will appear in the server list in Job Status and in the Animation plug-in's run selector.

Version 0.24.1 - Released 6/8/06:

• "One Touch Expand" buttons were added to the divider bar between the Navigator and Views tabs. These buttons can be used to completely hide the Navigator or the currently open Views by clicking the appropriate left or right facing arrow button.
• An issue was resolved in the Executables portion of the Configuration Tool that caused the "Supports Interactive Execution" and "Defaults to Interactive Execution" properties to be reversed.
• An issue was resolved in the submit dialog that would prevent the last selected executable from being used as the default for the next submit.
• Undo capability was added for the "Add to View" feature available for component and Category nodes in the Navigator.
• Logic was added to many of the component selectors (i.e. the blue S) that will ensure that the row containing the currently selected component will be visible in the selector dialog when it is opened.
• An issue was resolved in the Property View that would sometimes remove the last character from property tooltips.

Version 0.24.0 - Released 4/27/06:

• Resolved an issue that prevented parametric export using a temperature as the iterative constant. 
• The editor for modifying the size of connection handles was modified to limit the range of acceptable values. 
• Job Status was updated to more accurately display the dates and times included in the job table. 
• Modified the model import and load routines for every plug-in to cancel correctly if the cancel button is pressed during an import or a load. 
• An issue was resolved in the Configuration Tool that would prevent the calculation server status from being properly reported. 
• An issue was resolved in the Configuration Tool that prevented the "jEdit Executable" property from being saved. 
• A performance issue was resolved in the Calculation Server that could cause completed runs to be considered idle after 30 minutes even when the runs are currently being accessed.
