Version 7.7.3

AI metric bug fixes. Uploaded on 23 April 2020.

• Method 'initialiseValues' changed to 'initialise' in all classes. It is a private method, apart from the Function class. You will probably need to re-download any modules that you use.
• MetricDataset.toDataset has an error if you try to store lists as single entities, where the data type is also the list type. It would still split the list up and store each item as an individual element. This is now changed version so that getSingleValue will return the whole list, as the only stored element.

Version 7.7.2

Web service updates and bug fixes. Uploaded on 17 April 2020.

• Web services changed a bit with some bug fixes.
• Possible autonomic manager bug fix.

• Should fix the Feeds Service error.

Version 7.5.1 to 7.7

Server updates. Uploaded on 30 March, 3 and 4 April 2020.

• Communication bug fixes after removing the HttpCore base. Tested OK with XML-RPC and Rest_MethodHandler, but no guarantee about direct comm from a browser.
• Potential parser bug fix.
• Minor update to the server startup and settings.

Version 7.5

Server and Service updates. Uploaded on 9 March 2020.

• Information service filter terms now a list of comma-separated terms.
• In licas_internet: ConnectionManager.sendGetRequest now sendRequest. The connection classes now have 'Licas' at start of name.
• Removed HttpCore from the framework, so no third-party server now. Starting to overwrite some of the licas classes and then realised that HttpCore also serializes what is parsed first, which must be uneconomic.
• If there are any server problems, then if you send an email, I can correct it more quickly.

Version 7.4

Service updates and bug fixes. Uploaded on 20 February 2020.

• Information service GUI has some more config options.

Version 7.3

Service updates and bug fixes. Uploaded on 12 February 2020.

• The Sparql Query now allows nested Select clauses in the Where clause.
• Messenger service lists the current clients.
• Minor Feeds and Information service updates.
• Other bug fixes.

Version 7.2

Bug fixes. Uploaded on 2 December 2019.

• The 'Highlight' button on the GUI no longer freezes the GUI.
• Data query classes in org.licas.data changed a bit, and related classes. Evaluate method now returns a ReplySet, so alomst the same and some other bug fixes.
• InformationService now runs in a loop with a sleep time of 1 day, and with a basic Publish-Subscribe behaviour. So different to LinkService now. Default loop time speeded up. Any problems please let me know.

Version 7.1.2

Cluster Behaviour bug fixes. Uploaded on 11 November 2019.

• The cluster behaviours have been re-written for the new modules and may produce slightly different results. Probably improved the result. If any problems then please email me.

Version 7.1 to 7.1.1

Module and Service bug fixes. Uploaded on 30 and 31 October 2019.

• If using createResource, you need to use the Data-Value structure for the XML element.
• Serious communication bug fix, might be quite old.
• Module names changed slightly, so base module is now a 'FrameworkModule'. A new general rule is that modules directly in services extend 'FrameworkModule' only and any module being added as a child service should extend 'ServiceModule'. An exception is thrown otherwise.
• The cluster services have been moved to the core licas package and converted into heuristic modules. A small amount of change, some new AI classes and some classes moved over. Check the sci and AI packages. The cluster class names have changed, so you will need to redo any scripts for that.
• Feed service bug fix.

Version 7.0 to 7.0.2

New modular architecture and some fixes. Uploaded on 17-22 October 2019.

• The Service class is quite large now, so a new base ServiceModule class has been created. This will also convert the system over to a more modular architecture. It may require a few changes to your code, but the updates should be minimal.
• Some important bug fixes. The Link service autonomous behaviour has at least 1 error - it does not process the input message, but the default behaviours will be looked at again anyway. The Ai-heuristic evaluators (SimpleMathCompare) now process MetricDatasets as well.
• With the new modular architecture, the service behaviours are extracted to the modules, see the module package and ModuleHandler. Also see the documentation. All of the functionality should be the same. You may need to update some package names but nothing else.
• A new Data Module is used by the Service class and stores the data as a Resource. So this is now the default setup for every service now. The Service 'getData' method has been changed to return an Object. The method to look for is MethodConst.GETDATA. You might need to update your code for this. Also 'setDataObj' changed to 'setData' with slightly different interface.
• The problem solvers now pass objects as the data instead of always elements that then get parsed. The ProblemSolverMediator, for example.
• If running scientific services, you should not use the InformationService for clustering. Use the LinkService instead, as the InformationService will be given a different behaviour module and so will not automatically cluster data. You might need to update your scripts for this.
• The default clustering behaviour has been changed, but this will be looked at again.
• Auto Manager Module does not need both password handler and admin key in constructor, so admin key removed and taken from password handler internally.
• DataQuery now DataQueryModel, ComparisonQuery now ComparisonQueryModel, plus parsers.
