• #482 Change the limit of jms max reconnection attempts to 10 instead of unlimited.

Migration​

• From this release we start to modernize our technology stack. Our first step was to migrate the user interface. The Flow Manager, Tenant Manager, Instance Manager and Settings are migrated to the React Framework. Also, various components were migrated. More in the next release.

4.11.2​

Released on: Wednesday 30 June 2021

We reverted some changes that didn't work as expected which caused some components to behave in a weird way after a restart of the back-end.

4.11.1​

Released on: Thursday 27 May 2021

Improvement​

• #1690 We improved the memory allocation in the back-ends.

Bugfixes​

• #1675 We fixed a bug that made it impossible to search on breadcrumbId's in the transactions of an installed flow.

4.11.0​

Released on: Wednesday 12 May 2021

New features​

• #1579 We updated Elastic Search to the latest version. This also means that the flow logging and tracing will be reset after updating to this version. In combination with the update we also improved the processes that store logging and tracing so that it will be faster and more reliable. The new version also introduces a lot of new improvements and bugfixes which will benefit the stability and reliablity of the system.
• #1629 + #1648 We updated ActiveMQ to the latest version and at the same time we also improved the configuration for it. The improved configuration will remove some warnings that were reported in the flow logging and it allows flows to properly reconnect their queues when a connection fails. The new version also introduces a lot of new improvements and bugfixes which will benefit the stability and reliablity of the system.

Improvements​

• #1563 We made several improvements to the health checks:
  • The flow bundles reports now also detects flows that failed to install or are still installing. This will also show up in our monitoring.
  • The AMQ report now timeouts after 30 seconds, because when ActiveMQ is under heavy load it could take too long to get the information which would trigger a NGINX timeout. This ensures that the general health check always returns the other reports.
  • The version has been added to the instance report.
• #1636 We added a new option to the Excel to XML component that allows to disregard empty lines/sequences so that they are not included in the resulting XML.
• #1645 We reduced the logging of some components so that the flow logging shows more useful logs. These components are:
  • XML to JSON component
  • JSON to XML component
  • Split component
  • Aggregate component

4.10.1​

Released on: Wednesday 24 february 2021

Improvements​

• #1490 We made some improvements to the flow versions in the Flow Designer:
  • Installed versions are fetched asynchronously instead of synchronously.
  • The versions tab now has a loading indicator for fetching the list of flow versions and for fetching the installed flow versions.
• #1563 We made some improvements to the health reports:
  • Response status is now always 200 OK.
  • Ignore some warnings in the ActiveMQ report that are not important.
  • Issues in a report are now returned inside an array instead of in a string.
• #1577 We added a new advanced option to the HTTP component that allows to decouple the managed SSL certificates store. In very rare cases this could be necessary.

Bugfixes​

• #1558 We fixed the encoding error of special characters in environment variables and encrypted global variables.
• #1606 We fixed a bug in the Throttling component and in the Retry mechanism of the HTTP component that could cause the mixing of headers between exchanges.

4.10.0​

Released on: Monday 1 february 2021

New features​

• #1440 We added a new RabbitMQ component.

Improvements​

• #1424, #1507, #1563 We improved the reports that are generated by the health check endpoints.
• #1571 Files placed on the server by the File component will now survive an update of the instance. This is enabled after updating to this version so updating from 4.9.0 to 4.10.0 will not keep the files, but updating from 4.10.0 to 4.11.0 will keep the files.

Bugfixes​

• #1110 We now show the actual tracing setting of the installed flow in the Flow Manager and not of the last saved version.
• #1545 We fixed a bug that caused an error in the Excel to XML component when the selected range contained empty cells.
• #1569 We improved the calculation of the pending exchanges. In very rare cases it was not accurate and could lead to pending exchanges not being processed by the Throttling component.
• #1413 We fixed a bug in the JSON to XML component that caused nested arrays to not be processed correctly and in turn this caused missing data in the resulting XML.
• #1334 We fixed a bug in the XML to JSON component that caused namespace attributes to not be removed properly which generated an error.
• #1564 We fixed the configuration for sending user creation and forget password e-mails.

4.9.0​

Released on: Wednesday 9 december 2020

New features​

• #1520 We added new EDIFACT transformations to the EDIFACT Standards to XML component and we also have new transformations from XML to EDIFACT Standards so we have created a new XML to EDIFACT standards component for that.

Improvements​

• #915 We made several improvements to the FTP component:
  • Add options to sort on name or data.
  • Add option to only process a certain amount of files on each poll.
  • Add option to move picked files to an error folder when there is an error.
  • Add option to upload the private key file instead of specifying a path.
  • Add option to switch between charset and binary.
  • Allow both password and private key file to be specified for SFTP authentication.
• #1481 We added a lot of new UN/EDIFACT formats to the EDIFACT to XML component and the XML to EDIFACT component.
• We made some improvements to the HTTP component:
  • #1495 We added a new authentication method called Mutual SSL which allows to authenticate with API's via a password protected private certificate.
  • #1510 We added a new HTTP method Delete with body.
  • #1530 We deprecated the NTLMv2 component and added a new authentication method for NTLM to the HTTP component.
  • #1540 We improved the working of the retry mechanism.
  • We improved the certificate validation of more advanced HTTPS URL's.

4.8.9​

Released on: Thursday 28 October 2020

Bugfixes​

• We fixed two bugs in the Throttling component:
  • #1499 A synchronous flow with a Throttling component could not be installed.
  • #1508 The Throttling component now always needs a connection on the right to prevent mistakes which could lead to increased disk space usage caused by unprocessable messages.
• We fixed a two bugs related to the retry mechanism of the HTTP component:
  • #1500 It didn't work properly in synchronous flows.
  • #1505 The Exclude headers didn't work together with the retry mechanism. Excluded headers were not set back after the HTTP request.
• #1503 We fixed a bug that corrupted passwords with certain symbols in the SQL component. This caused the login to fail when it was running in a flow.
• #1511 We fixed a bug in the File, FTP and Samba components so that the Delay and Initial delay fields are not validated when the Force inbound is set to Yes.
• #1512 The File, FTP and Samba components in older flows will get a proper default value for the Force inbound field.
• #1514 We fixed a styling bug that caused the tenant dropdown to be overlapped by the validations sidebar in the Flow Designer.

4.8.8​

Released on: Thursday 15 October 2020

Improvements​

• We improved the calculation of the completed, pending and failed exchanges in the statistics for the Flow Manager. The statistics are calculated in the background and not on demand. This decreases the load time of the Flow Manager when many flows are installed. This also means that the shown statistics can be a bit "older", because they aren't calculated on demand. The statistics can still be requested on demand for each flow by going to the details of a flow.

4.8.7​

Released on: Tuesday 29 September 2020

New features​

• #1411 We added new connection settings to the HTTP component so that the throughput can be increased/decreased depending on how many messages the endpoint can handle. The defaults of these settings are set in the server configuration so we can increase/decrease them when needed. When we do this before the deploy of this release all HTTP components will get the new defaults, but when we change it after the deploy of this release only the new and not opened HTTP components will get the new defaults.

Improvements​

• #1464 Now we show Loading... instead of undefined (#undefined) while the data of a flow is being fetched on the Flow Details page.
• #1471 The navigation bar is now sticky. When you scroll down on longer page (e.g. Flow Manager, settings,...) the navigation bar will stay at the top of the screen.
• #1220 + #1300 We improved the Throttling component. The messages are now stored in a queue in ActiveMQ instead of in memory. This reduces the memory consumption of the component when throttling many messages. Because of this change simple expressions don't work anymore in the Max requests field.

Bugfixes​

• #1463 We fixed a bug that caused warning messages from ActiveMQ to show up in the flow logging for components with exchange pattern options that are set to One way.
• #1464 We fixed a bug that caused an error message to show up in Flow Details page when switching tabs while the details were still loading. This error message should only show up when flow data is not loaded correctly, but in this case all flow data still loaded correctly.

4.8.6​

Released on: Friday 11 September 2020

New features​

• #1304 We added a pending exchanges flow statistic to the Flow Manager tables. This will show you how many messages each flow is still processing. This also replaces the high load notifications.
• #1381 The HTTP component has a new user interface that provides better support for the user when configuring the component. It also has a new retry mechanism that can be turned on to store and retry requests that failed because the HTTP endpoint was unavailable.
• #1443 It is now possible to increase the amount of concurrent connections that each HTTP component can open. This increases the throughput of all HTTP components that are running in flows. Please note that this has to be configured by us in the server configuration and needs a redeploy to apply it to all running HTTP components.

Improvements​

• #1380 We improved the user interface and user experience of the File component, FTP component and the Samba component. Only the settings that apply will show up now to avoid confusion. This provides better support for the user when configuring the component. The component can either be inbound or outbound based on how it is connected to other components in the flow. There is also a new option Force inbound that can be used to consume files in the middle of a flow without putting it below an Enrich component.
• #1408 The format of the Inbound HTTP URL's has been changed for better compatability with planned changes of the URL. The older formats are still supported, but are not shown in the UI anymore.
• #1410 We added automatic cleanup of stale messages in queues of ActiveMQ. Messages that stay in a queue for 24 hours will be removed.
• #1166 The max body size of the Inbound HTTP component has been increased from 1MB to 10MB. We also made it possible to increase this by changing a configuration setting in the server configuration. Please contact us if you need a higher body size.

Bugfixes​

• #1391 Support special characters in the password of the Samba component.
• #1438 The NTLMv2 component now also supports HTTPS URL's.

4.8.5​

Released on: Monday 18 May 2020

Improvements​

• #1186 We added a new Exclude headers option to the HTTP component. It allows to exclude specific headers from the exchange so they are not included in the HTTP requests.
• #1199 The FailedExchange component doesn't retry failed exchanges by default anymore. We set the maximumRedeliveries to 0.
• #1241 The HTTPS URL's of the Inbound HTTP now don't include a specific port anymore and look nicer. This also improves the support for applications that don't support setting specific ports on URL's.
  • Attention: existing (old) URL format still works so it is not necessary to change the existing URL's. See Using Inbound HTTPS in the Inbound HTTP documentation.
• #1248 Better response status handling in the NTLMv2 component. The correct response status is returned when there was an error.
• #1312 Properties modals of components that have an updated UI can now also be stretched vertically instead of only horizontally.
• #1326 We updated the Samba component:
  • It can now be properly used in combination with the Enrich component.
  • It now supports version 2 of the SMB protocol.
• #1347 When the Recipient component is set to Request reply it now indicates which recipient will be used as response to the caller.
• #1358 The input labels are a bit bolder in the component properties modals with an updated UI.
• #1364 We made two improvements for the Excel to XML component:
  • The XML Node names don't have to be unique anymore.
  • Invalid XML characters will be filtered out from the header row values automatically, when the Has header row option is enabled.
• #1371 Remove some AMQ settings which limited the amount of components that could be used in a flow.
• #1377 We made some small improvements in the SOAP component:
  • Higher connection and socket timeouts when fetching WSDL's for slower SOAP services.
  • Better logging related to the SOAP WSDL cache.

Bugfixes​

• #999 We fixed the format of the datetime values of the Last completed exchange and Last failed exchange in the details view of a flow in the Flow Manager.
• #1114 The password editor in the Tenant Manager mail settings doesn't show the passwords in plain text anymore.
• #1288 The root tag and array element name validations in the JSON to XML Current component are now only executed when the correspondig inputs are visible.
• #1249 We fixed a bug that caused session cookies with a fixed expiration date in the browser. This could lead to users not being able to login after some time.
• #1346 We fixed the behaviour of the Recipient component when it is set to One way. The incoming body will be properly returned now.

4.8.4​

Released on: Wednesday 1 April 2020

Deprecations​

• #1244 We removed the Bol component, because it still used the deprecated API of Bol.com. The Bol API is now simpler so a custom component is not necessary anymore.

Improvements​

• #1306 We added the following new marketplace regions to the Amazon component:
  • Netherlands
  • United Arab Emirates
  • Saudi Arabia
  • Singapore
• #1322 We now import the groovy-json module so its functions can be used in the Script component.

Bugfixes​

• #1247 We fixed the URL of the NTLMv2 component. Whitespaces are now allowed in it.
• #1248 We fixed the error codes of the NTLMv2 component. It now returns the correct error code when the request failed.

4.8.3​

Released on: Wednesday 18 March 2020

Bugfixes​

• #1293 We fixed a bug in the Split component related to the changes we made for the exchange pattern option. Along with this we also made some other improvements related to exchange patterns.

4.8.2​

Released on: Tuesday 17 March 2020

Improvements​

• #1273 The Email component now supports binary body as an attachment.
• #1293 The components with an exchange pattern option now give back a response to the caller before being routed as an One way exchange.

4.8.1​

Released on: Friday 6 March 2020

Breaking​

• #1141 The Excel to XML component now generates excelCol elements instead of excelRow elements when the transpose option is enabled.

Improvements​

• #1282 We added an exchange pattern option to the Content Router component.
• #1141 The Excel to XML component has a new option so that the header row of an Excel document can be used to name the XML elements.

Bugfixes​

• #1223 + #1283 We fixed the manual validation of expressions in the Content Router component and the Set Headers component.
• #1277 We fixed a bug which caused some Groovy Scripts to fail after restarting the back-end.

4.8.0​

Released on: Wednesday 27 february 2020

New features​

• #1155 We addded new components to consume files from and upload files to Google Drive: the Inbound Google Drive component and the Outbound Google Drive component.

Improvements​

• #354 We updated our Camel version to 2.23.4.
• #1168 The Split component now sets some headers on each splitted message which can be helpful. Information about these new headers has been added to the Split component documentation.
• We added an Exchange pattern option to the Split component.
• #1252 The XML JSON current component has a new option to remove the root object from the JSON output.

4.7.2​

Released on: Monday February 3 2020

Improvements​

• #853 We improved the Inbound e-mail component with a new Content option that allows you to process both the body and attachments of an e-mail.

Bugfixes​

• #1242 We fixed a bug in the Outbound Flow Link component that caused wrong behavior when used at the bottom of a Split component.

4.7.1​

Released on: Thursday January 23 2020

Improvements​

• #1154, #1174, #1188, #1202 #1214 #1230 Multiple improvements for the new XML JSON components:
  • XML to JSON: add a new type hint array.
  • XML to JSON: XML attributes are prefixed with @ in the resulting JSON.
  • XML to JSON: XML attributes other than type also show up when XML node has type attribute.
  • XML to JSON: fix bug that caused XML nodes with name "type" to not show up or weird JSON output.
  • JSON to XML: The name of the root tag can now be customized.
  • JSON to XML: JSON with a root array is now supported.
  • JSON to XML: new option to change the name of the array elements in the resulting XML.
  • Refactored the back-end code for improved performance.
• #1053 We improved the processing of attachments for the Inbound email component. When content option attachments is selected it will also process the body when there are no attachments in an email.
• #1206 The Recipient component now always shows the order of how messages are routed and it has a new option to determine the routing behavior.

Bugfixes​

• #1148 FTP components with the FTPS protocol now support SSL Session reuse which is required by some FTPS servers since it also improves security.
• #1190 Give the Split component a fixed exchange pattern. This ensure that the component always has the same expected behavior. In some flows the components before a splitter could set a different exchange pattern which caused the splitter to changes its behavior.

4.7.0​

Released on: Friday November 15 2019

New features​

• #165, #789, #1058, #1083, #1106 We divided the Flow link component into a Inbound flow link component and a Outbound flow link component. We did this to make it easier to use and fix some issues with it. The original Flow link component is now deprecated.
• #973 We added an S-flag parameter to the Replace component that enables the dotall mode.
• #1176 We added an exchange pattern option to the Inbound HTTP component, so it would work better together with the new flow link components.

Improvements​

• #343 We improved the memory settings for ActiveMQ which results in better overall stability.

Bugfixes​

• #1080 We fixed the CRON input of the Scheduler component so that the selected day is also the day on which the scheduler will run. For example: you had to schedule a CRON job on Wednesday if you really want to run it on Tuesday.

4.6.1​

Released on: Wednesday September 25 2019

Bugfixes​

• #988 We fixed the bug that caused errors in the Set Global Variable component when the message body contained the dollar symbol ($).
• #1145 Regression: the fix for slow saves in the Flow Designer was omitted by mistake in release 4.6.0 and is now added back.

4.6.0​

Released on: Thursday September 19 2019

New features​

• #1022 New Excel to XML component. It allows you to transform parts of Excel files into XML. Checkout the documentation to learn more.
• #173 New and improved JSON to XML and XML to JSON components. These should provide better transformations for XML and JSON and solves some issues. The old JSON to XML and XML to JSON components are deprecated and will be removed in a future release.
• #1023 Two new endpoints for sending/receiving HL7 messages:
  • Inbound HL7 component
  • Outbound HL7 component

Improvements​

• #1057 We improved the tracer and fixed some issues along the way:
  • The order of transaction messages is now correct. They follow the order in which the messages were sent between the components.
  • It is faster. Heavy flows now won't be affected when they have tracing enabled.
  • It doesn't interfere with flows anymore. In some situations the tracer could change the behaviour of a flow.

4.5.7​

Released on: Wednesday September 18 2019

Bugfixes​

In this release we fixed two bugs for the Inbound HTTP component:

• #1091 The validation for the endpoints is improved. It now ignores differences in casing. For example: test will be the same as TEST. When two flows would be installed with these endpoints, only one of them would get called.
• #1103 The combination of an environment variable as Endpoint and Match prefix? set to true would cause an error when validating other Inbound HTTP components. This error would cause most of the Inbound HTTP components to become invalid in the other flows.

4.5.6​

Released on: Wednesday September 12 2019

Bugfixes​

• #1082 We fixed an exception caused by the Replace component that occured when it processed an exchange before it was sent to an HTTP component.
• #1123 We fixed a bug that occured after saving a flow. In some cases this could cause the user interface to completely freeze causing the page to become unresponsive.

4.5.5​

Released on: Tuesday August 6 2019

Improvements​

• #865 The validations of the Set Headers component and Content Router component in the Flow Designer has been improved. Expressions with environment variable placeholders will be validated in the same way as expressions without environment variable placeholders.
• #865 The tooltip that shows up when hovering environment variable placeholders now shows the value of the environment variable for each environment. Before it only showed the value for the test environment.
• #1035 The tooltip that shows up when hovering environment variable placeholders now works better when there are multiple environment variable placeholders. It now shows the values for all the placeholders.
• #1047 We have made several improvements in the amount of threads the backend uses on the server:
  • Stop opening new threads when the health check is called.
  • Remove a big unused dependency that opened threads.
  • Improve the settings for ActiveMQ which should reduce amount of threads for flows with many Wire taps.
  • The Wire tap now by default could discard messages when it is encountering heavy load.

Bugfixes​

• #1002 We fixed the alert that appeared when leaving a flow that has unsaved changes. It showed the code instead of executing it.
• #1039 We fixed an issue where the connection test of the SQL component could fail when it shouldn’t because of special symbols in the username, host, password or database name.
• #1033 We fixed an issue with the EDIFACT to XML component where it could generate some errors while processing exchanges.

4.5.4​

Released on: 13 June 2019

Bugfixes​

• #1019 Due to the upgrade of Camel it handles Byte Order Marks differently. This caused issues in the FMUTA component resulting in missing output. This has been fixed now together with the radio button that didn't seem to work properly.

4.5.3​

Released on: 7 June 2019

Improvements​

• #1012 + #1013 Update some front-end dependencies to fix security vulnerabilities.

Bugfixes​

• #303 We upgraded Camel again to version 2.22.4 to fix a bug related to the FTP component when SFTP is used.

4.5.2​

Released on: 5 June 2019

Improvements​

• #995 We improved the validation of the endpoint in the Inbound HTTP component.
• #986 We improved some statistics of the health check:
  • ActiveMQ check now also returns the status FAILING if things are really going wrong.
  • The flow bundle report now also reports if there are stopped flow bundles.
  • The thread counts are checked better now and will return TROUBLING or FAILING status when reaching certain tresholds.
• #991 We improved the caching of the JavaScript files and CSS files in the browser.
• #299 We upgraded Camel to version 2.22.0.

Bugfixes​

• #286 + #298 We fixed some bugs and refactored some code in the SOAP component.
• #300 We now also support the BEGIN SQL operation in the SQL component so it can be properly used with the Oracle 12c database type.
• #801 We fixed a bug that caused the copying and pasting of a Recipient component to not work properly. It would cause an error when trying to install the flow that contained the pasted recipient.
• #949 We fixed a bug that made it possible to create flow groups with duplicate names.
• #975 We fixed the password validation when activating a new user. Some passwords were marked as invalid while they were valid to use.
• #976 We fixed the bug that would cause a new Split component to be replaced with a deprecated Split component when a flow was imported.

4.5.1​

Released on: 7 May 2019

Bugfixes​

• #964 We fixed a bug for the SQL component which made it impossible to connect to a SQL database of the type SQL Server.
• #909 We fixed some logic of some components which should resolve the problem that some flows would not be restarted after a deployment or server restart.
• #971 We improved the Override File type in the Enrich component so it throws a useful exception when the body that comes out of the bottom route is empty.

Improvements​

• #292 We added thread count and peak to the Karaf report of the health API.

4.5.0​

Released on: 17 April 2019

New Features​

• The NTLMv2 component now supports simple expressions to create dynamic URL's.

Improvements​

• We improved/added the threadpool settings which should increase the stability.
• We split our queueing system per environment so asynchronous flows from test can't take down the queueing system of the production flows anymore.

4.4.1​

Released on: 19 April 2019

Bugfixes​

• #964 We fixed a bug in the SQL component that made it not possible to connect to SQL Server type databases.

4.4.0​

Released on: 12 April 2019

Deprecations​

Starting from this version there is a deprecated version of the Split component, because the new version also has the improved Aggregation strategy which can change default behavior.

New Features​

• #166 It is now possible to see the logs and transactions of uninstalled flows in the Flow Manager.

Improvements​

• #938 We added two options to the Inbound HTTP component which improve the usability.
• #826 We added the completionCountTimeout option to the Aggregate component so you can also set a timeout for the completionCount option.

Bugfixes​

• #918 We fixed the behavior of the new Enrich component when a FTP component is connected to the bottom.

4.3.3​

Released on: 8 March 2019

Bugfixes​

• #800 We removed the recordSeperator option from the CSV to XML component

4.3.2​

Released on: 4 February 2019

Deprecations​

• #797 Starting from this version we deprecated the Enrich component and the Aggregate component, because new versions are available which have different behavior. The new version of the Enrich component now also puts Enriched XML tags around single message enriched bodies for XML. The new version of the Aggregate component now also puts Aggregated XML tags around single message XML aggregations.

Bugfixes​

• #845 We fixed a bug in the Content Router which could lead to a lot of persistent data in the queueing system.
• #819 We fixed a bug which caused some components to accept multiple incoming connection lines. We don't support this yet, so we removed it to avoid confusion.
• #849 Since 4.3.1 the Throttling component dissapeared from the component library. It is now available again and we added some preventive measures to prevent this from happening again.
• #855 + #856 We fixed a bug in the Enrich component which caused it to not output any message when it had no connections on the right.
• #866 We fixed a bug in the tracing which could cause some exceptions during flow execution.

4.3.1​

Released on: 9 January 2019

New Features​

• #770 We added the possibility to add an authentication token as an HTTP header in the SOAP component, so WSDLs that need one can be accessed.
• #253 Add support for ${bodyAs(String)} in the global variable components and the SQL component.

Improvements​

• #818 We removed the deprecated split component. Deprecated split components in flows will be migrated to the current Split component.

Bugfixes​

• #812 Some flows could not be moved to other flow groups.

4.3.0​

Released on: 12 December 2018

New Features​

• #147 New! Revised Front-End Technology, we updated some technologies used for representing UI in the webbrowser which will result in better stability and more features in the future.
• #149 We added the functionality to validate components regarding their positional connection, which means we can now do more specific validations to help the user design their flows.

Improvements​

• #168 Because our users had a difficult time figuring out which installed flows where using tracing, we added the value in the Flow Manager page.
• #197 We improved our login system by not bothering users to login every now and then, if you want to prevent any unwanted access you can just log off manually. With this we also got rid of our back-end token validations which often caused trouble.
• #761 Don't open the Flow Manager in a new tab when navigation from the version tab.
• #150 When adding a new rule in the Content Router component, the new rule will have the same expression type of the previous expression.
• #794 We improved the validation message of the Inbound HTTP component so it is more clear what is allowed and what not.
• #786 FlowLink components will be empty now when you import them via a flow import.

4.2.0​

Released on: 18 October 2018

New Features​

• #643 New! With this version we support multiple environments, rather then just Production & Test. This can be arranged in a few clicks with the support team.
• #886 New! Static environment variables, these variables are automatically filled for every new, and existing flow, prefixed with self.<variable>. Read more.

• #542 When using the Recipient component, it's now clear in which order the endpoints will be executed when the flow is put synchronous.
• #667 When using the Remove Headers component the breadcrumbId header will be automatically excluded as it is used to track transactions in the tracing log. You can still remove this by explicitly name it in the exclude pattern.

4.0.4​

Released on: 30 May 2018

New Features​

• #896 + #906: When HTTP or Email endpoints use custom SSL Certificates, we can now import these into our back-end without having to restart it.
• #898: New! Oracle 12c Database connection support, for the SQL component. It means literally what it says, you can now connect to your Oracle database from the SQL component.

4.0.3​

Released on: 7 May 2018

• GDPR: Added restrictions on the session cookie the platform uses to remember who logged in. These restrictions make sure only your instance can access these.
• #812: When transforming XML to JSON we often got the question why everything is by default a string, and null values were automatically an empty array ([]). We added an option so you can specify in the source XML the type of value it contains so the component knows this when it transforms it into JSON. See the documentation for more information.
• #842: We added a health check API to monitor instances more specific and more accurate.
• #852: We added a favicon.
• #861: Looking at the new Split component a few questions were raised on the TimeoutExceptions, we decided to make the timeout for asynchronous flow configurable in the flow settings tab, and add an option to split parallel. For the parallel option read the documentation for more information.

Improvements​

• #887: Added support for Office 365 SMTP Mailbox in the Tenant configuration.
• #891: Whenever an exception occurred in the bottom route of the Enrich component, it was not logged into the Flow logs, and no failed exchanges were displayed. Backwards compatibility-wise we decided to just log it in the flow logs, instead of letting the exchange go to the error route as it could break current installed flows.

Bugfixes​

• #877: Fixed an issue where the Samba component would not work due to the dependency not being available for the 4.0.1 version.

4.0.1​

Released on: 17 April 2018

Warning​

• With this version, all flows need to be reinstalled manually. This is unavoidable because of the fact that we "reinvented" the way we gather statistics about flows (not related to data, just numbers).

New Features​

• #269: We added the functionality to copy and paste components with their config preserved. This can be between flows, but unfortunately not between tenants as that would be some sort of security risk. For more information read the documentation page.
• #591: New! Amazon component, this component allows users to integrate with the Amazon Marketplace. For more information read the documentation page.
• #608: Superadmins can now specify the number of flows that a tenant is allowed to run in production. This can be configured in the Instance Manager.

Improvements​

• #329: When scrolling through your versions in your Flow Designer it is now possible to click on the environment of an installed version to go to its Flow Manager Details page.
• #677: When connecting flows through the FlowLink component you often got duplicated tracing in both flows. This issue has been resolved and you should only see the components of the current flow.
• #689: When tracing a flow that is connected to a FlowLink component, tracing will add a link to the calling and receiving FlowLink so you can easily navigate through the tracing.
• #741: We added the functionality to override properties in the Bol.com component with headers. This allows users to create dynamic values and pass them to Bol.com, read the documentation for more information.
• #755: When creating a new flow, the flow group that you were currently in will now be selected by default in the pop up view.
• #775: We made several improvements in the usage of the Content-Router, which should now be more easy to use.
• #778, #799, #845: With 4.0.0 introducing the validation message tab, we were inspired with a lot of ideas and opportunities which we all tried to implement in this version. We added information messages and warning messages to help you in designing better flows.
• #803: We added the Tenant's creation date and last updated to the Instance Manager view.
• #854: We now support more HTTP method calls in the HTTP component! We added: HEAD, PUT, DELETE and PATCH.

4.0.0​

Released on: 29 March 2018

Warning​

• With this version, all flows need to be reinstalled manually. This is unavoidable because of the fact that we "reinvented" our whole back-end system and upgraded several systems for better reliability and performance!

New Features​

• #181: FTPS is now available as FTP Protocol in the FTP component.
• #462: New! Validations tab. In addition to our validations and pre-install checks in the Flow Designer, we now added a validations tab that shows you the exact validation message per component. Making it easier and faster to debug your flow. Check the documentation for more information.
• #544: Update to Apache Karaf 4.2.0.M2 release.
• #682: Update to Apache Camel 2.21.1 release.
• #711, #813: New! Transaction Tracer. Previous to this version we used an Apache Camel tracer to trace our message's through the flow. Unfortunately, we discovered that this Tracer was unreliable and deprecated in the new Apache Camel versions. The new Tracer is 100% asynchronous and will never interfere with your main route. Important to note is that the Tracer will always show the message going into the selected component, whereas before it showed the message leaving the selected component.

Improvements​

• #610: XPath 2 functions are now fully supported again in all XPath expressions.
• #696: Improved the experience when clicking flow versions, by not automatically scrolling back up the versions but staying on the version you clicked.
• #766: This version will have revised component icons.
• #767, #768: Improved security of our routing between our local proxy and back-ends, now all using SSL.
• #777: Expression validations are now run with the same validator which results in better and more consistent validation results.
• #795, #786: We renamed the IftminToXml component to EdifactStandards component for a better user experience, and also added more standard Edifact transformations. This component still only works one-way, from a standard Edifact to XML.
• #797: For security reasons we decided to not show potential stack traces in the response of the Inbound Email component. We do however show a small message to give a clue about what might be wrong. The full stack trace remains available in the logs tab in the Flow Manager.
• #787, #806: Due to an upgrade of the Java Mail library in Apache Camel we had to improve/update some configuration files to make the Inbound Email component work again.
• #810: We now removed the deprecated Soap component in favor of our new Soap component.
• #813: We have made huge improvements to the Soap component generating reliable automated tests which result in improved performances and wider support of WSDL variations.

Bugfixes​

• #286: Fixed an issue where environment variables would not show/validate correctly in the Error Route.
• #749: Fixed an issue where the operation in the Soap component would not be sorted alphabetically.
