Neuron 2.5.14.0 Change History Msmq Topics FIX - Error messages now indicate the name of the topic and server, or the path to the queue. Messaging FIX - If MSMQ is stopped and restarted while Neuron is running, Neuron will clear stale connections to the MSMQ server and re-establish connections automatically. NEW Added the Log No Recipients property to the MSMQ network properties page. This will log a warning to the Neuron ESB event log if a message is published when there are no subscribers for it defined. NEW Custom Message properties can now be preserved between request/response calls. A new property, ESBMessage.Header.RequestHeadersToPreserve, has added to enable this. i.e. ESBMessage.Header.RequestHeadersToPreserve = prefix.propertyname1, prefix.propertyname2 NEW TransactionId has been added to the ESB Message header and is preserved between request/response calls. This is read/write NEW ParentId has been added to the ESB Message header. This is set to the message id of the parent message Adapters NEW An ODBC adapter is introduced in this release.

Supports using dynamic connection strings to connect to the database. This can be set within a pipeline code step i.e. context.data.setproperty( odbc, ConnectionString,<somevalue>) NEW An SMTP adapter is introduced in this release. This augments the existing EMAIL adapter. This adapter supports dynamic setting of SMTP properties, XSL transform for message bodies, attachments, InfoPath as well as delivery notifications. Service Policies NEW Support has been added under the Availability tab of Service Policies for customization of the SOAP Fault returned to the calling client when Limited Availability of an Endpoint is enabled. This message can be customized to include either the service name, the service endpoint url or both i.e. The Neuron end point, '{0}', configured with the following url, {1}, is not available. Message Resubmit NEW The ability to edit and resubmit messages within the Message Viewer has been completely refactored. Users can now edit a single message and resubmit that message directly
to a Party (which runs associated pipelines) or, to an Adapter or Service Endpoint (which would not run associated pipelines). NEW Bulk edit and Resubmit of messages has been added. Users may selected multiple messages in either the Message History or Failed Message reports and choose to edit and then resubmit all directly to a Party or, to an Adapter or Service Endpoint. Reporting FIX Selecting multiple records in either the Message History or Failed Message report window would sometimes cause a null pointer exception when the Message Viewer was displayed. This has been corrected NEW Performance Counters have been added for Neuron Endpoints and Neuron Topics. The existing esb client performance counters have been renamed to Neuron Parties. All Performance counters can be enabled through the General tab of Zone configuration within the Neuron ESB FIX- Split Pipeline Step : Context properties were not being properly propagated to the individual split message contexts.

NEW Exception Pipeline Step : Information regarding the source pipeline and pipeline step that generated the exception has now been added to the Data collection within the System.Exception object accessible within the Catch block of the Exception Pipeline Step. NEW Pipeline Execution Pipeline Step : Support has been added to allow selection and execution of pipelines that exist in external/third party ESB Solution files. FIX An unhandled exception would occur if the Neuron ESB could not load a custom developed Pipeline Step. This has been corrected NEW Audit Pipeline Step : New XPath property has been added. By default the entire message is stored in the audit table. When an XPath is used, the value (result) of the XPath expression will be stored as the message body. FIX An Xml Serialization error would sometimes occur when testing Dynamic Transforms and Dynamic Schemas within the Pipeline Designer or within Visual Studio.NET. This has been corrected. FIX Code Pipeline Step : Users would sometimes experience the Code Pipeline Step moving to a different branch or location within the existing pipeline when the Code Pipeline Step was opened and then closed. This has been corrected.
Installation FIX When performing a tools only install, the Neuron ESB would fail due to a missing dependency. This has been corrected. Neuron ESB FIX Deployment Groups A disabled party in ESB Solution that is subscribed to a nonexistent topic would cause a Null Reference Exception to be thrown when a Deployment Group was selected within the Neuron ESB. This has been corrected. SQL Server Adapter NEW - Adapter now supports using dynamic connection strings to connect to the database. This can be set within a pipeline code step i.e. context.data.setproperty( sql, ConnectionString,<somevalue>) Client Connectors FIX Message Counter value displayed in Endpoint Health Monitor would not increment if an exception occurred.
