3.6.0

Released: April 2nd, 2020

Important:

Because of a queue-related bugfix (see bugfixes) in 3.6.0, you will have to adjust the update-mechanism. Please first manually stop ``service-parser``, visit the RabbitMQ management panel and delete the ``service-parser`` queue. You can then start the update to 3.6.0. If you don't follow these steps, our ``service-parser`` microservice will not be able to start. Please contact ``[email protected]`` if you have any additional questions.

Features

Finnish & Swedish NLU

We have introduced Finnish and Swedish as new officially supported languages in our product. Please consult our installation- & dev-ops manual in order to get all details on how this language can be enabled on an infrastructure level.

Connection-Strings for MongoDB database connectors

We have added the ability to switch between specifying individual fields or a full connection-string for a MongoDB database-connection. This will allow customers to connect to a replica-set hosted on e.g. Mongo Atlas.

Extend support for additional HTTP verbs in transformers

We added support for additional HTTP verbs (other than POST) for endpoint input-transformers for the following endpoint-types:

• REST
• Webhook

The input-transformers of those two endpoint-types will now also be executed if e.g. a GET-request arrives and hits the endpoint-url. You can utilize this functionality to e.g. implement a verification process most of external platforms use.

NLU transformers

With our 3.5.0 release we have introduced endpoint-transformers which give you more possibilities to create your own integrations with third-party platforms. With NLU-transformers, we extend the ability to inter-connect with external NLU platforms as well.

Configurable TTL for contact-profiles & session-information

Until now, contact-profiles and session-information could only get dropped upon request. We have now added the ability to configure a TTL (=time to live) for those objects. Once configured, our software will drop those objects automatically.

Custom questions

We have added the ability to ask custom questions within Processes. These allow you to ask a question and e.g. trigger a webchat plugin in order to give the user a nice possibility to answer your question - e.g. by using a multi-select.

3.4.0

Released: September 18th, 2019

Features

Project templates

We added a new wizard that supports you when creating a new project within our product. The product can now get bootstrapped from one of our English / German project-templates which help you to get started even faster.

Twilio Autopilot

We now officially have a new endpoint for Twilio Autopilot! This endpoint allows you to connect autopilot to Cognigy.AI and use autopilots NLU capabilities. In addition, this endpoint also has a new built-in NLU connector that helps you to translate the NLU outputs of autopilot into the Cognigy.AI format.

Microsoft Bot Framework

We now have a Microsoft Bot Framework endpoint. This allows you to use adaptive cards in e.g. channels like Microsoft teams. Fields within those cards which have an id and a prefix of cognigy_ will trigger our NLU engine.

Userlike

We now have an official Userlike endpoint within our product.

Intent injection

We added the ability to directly trigger an intent by sending an arbitrary text-input pre-fixed with cIntent:. Customers can use this within their e.g. rich-media payloads to directly trigger an intent if a user e.g. clicked a certain button.

Intent trainer records import & export

We added the ability to import/export intent trainer records. Customers can use this feature to export intent trainer records from e.g. their production environment, import them into their dev environment and refine their bots, there.

Overwrite analytics-data

We added the ability to overwrite certain analytics properties within Code nodes. This allows customers to implement their own logic to e.g. set the understood or intent field, right before we store them.

Inject & Notify API for more endpoints

We made our inject and notify APIs compatible with a wider variety of endpoints. Customers can use these APIs in projects where long running processes get started by a bot and where the process will come-back to the bot after a longer period of time.

Any-slot

We added a new concept to the example sentences of ML-intents - the so-called any slot. Any-slots will be highlighted within example sentences and have a syntax of <<slot>>.

Rich-media editor for default replies

We added the ability to use the very same editor you are already using in say nodes for our default replies. This allows customers to send back rich-media (e.g. a gallery) when a default reply was triggered.

Intent tagging & searching

We added the ability so intents can be tagged. Developers can then search through their intent-list by name and by tag.

Organization level quotas & limits

We introduced the ability to set organization specific quotas and limits. This is especially interesting for our customers who are using our product in multi-tenant mode.

Typescript & Code-Nodes

We have slightly re-styled our Code-Node editor and added full support for Typescript! This allows customers to use the power of Typescript and e.g. define Interfaces and use them within their Code-Nodes. The feature is meant for developers and power-users who have large Code-Nodes in place. Simply write Typescript into your Code-Nodes - we will transpile it to modern JavaScript and execute it.

Improvements

• Removed an internal error message that would get displayed in the UI even though everything is fine
• Changed the way how the webchat demo page isolates the endpoint token from the URL. This helps to support API gateways that might sit in front of a Cognigy.AI installation.
• We slightly improved our NLU for German and added the word sofort to be handled correctly (similar to jetzt)
• Improve our Japanese NLU
• Improve security on users page by not exposing the email within the browsers URL. We are now utilizing the underlying user id
• Improved security on our livechat where agents could see chat-requests with bots in projects they had no access to
• Expose http response headers within the context when a httpRequest node is used to send requests
• Adjusted location for tooltips displayed on select fields within the toolbar of our application. The old tooltip location would often interfere with the mouse-cursor and would make some select fields not editable
• Introduce a new menu to delete custom modules more easily
• Improve the editing experience for lexicon tags and lexicon keyphrases
• We added the ability to jump into a flow if you open a executeFlow or switchFlow node. This helps developers to navigate through their interconnected flows during editing
• update our geo ip database so it contains the latest ip ranges for analytics purposes
• Improve the information of errors when thrown e.g. in Code nodes. This allows to developers to jump into the flow which produced the error
• We added a case sensitivity flag to our NLU settings. Customers can now decided, whether casing should have an impact on e.g. their intent mapping
• We added the ability to use a hotkey to save changes within Code nodes
• We added a new return value for the intent field when no NLU model was trained. The input object will then contain an intent field with an appropriate information that intents need to be trained
• We added the ability to use system slots for intent mapping within your example sentences
• We added the ability to delete, rename and copy a project resource within the project overview
• A Flow's language can now be changed after the flow was created
• We added the ability to add a label to flow nodes
• We added the ability to sort intent trainer records by count and timestamp
• We added the ability to render Microsoft adaptive cards in the Interaction Panel
• We render information in the Interaction Panel when a switchFlow event occured. Users can also click on the name of the Flow to directly jump into it.
• We now offer separate containers for NLU services of different language. This greatly improves the scalability of installations with multiple languages and higher load.
• We improved our ODATA interface which can now be used to e.g. retrieve conversation data
• We added alphabetical sorting for custom modules in the overview page and within the Flow Editor

Bugfixes

• Fixed a bug where the whole http response was checked for its size, instead of the response body
• Fixed a bug where the request was not anwered directly after a webhook endpoints payload was validated
• Fixed a bug where the project settings would not get applied after a switch flow or execute flow node, this would result in an NLU timeout in certain conditions

• Fix negation in our NLU pipeline
• Fix a caching issue for our ODATA analytics endpoint
• Fixed a bug where CognigyScript within confirmation sentences would not work properly

• Fixed a bug where analytics would not get stored when a default reply was triggered
• Fixed a bug where the attachedFlow view could sometimes crash and disappear
• Remove the EnableFileUpload flag for the new webchat endpoint editor. The new webchat supports file-uploads through a custom file-upload plugin, which is not loaded by default
• Fixed a bug with incorrect line breaks within a CognigyScript field
• Fixed a bug where a system state license error could get displayed after login
• Fixed a bug where the Facebook Messenger Endpoint settings would sometimes not work and behave properly
• Fixed a bug related to Google CANCEL intent in Cognigy processes
• Fixed a bug where the intent trained status would get reported the wrong way
• Fixed a bug within SMTP connections were you could not reliable send emails from within our system
• Fixed a bug where a project could not get created when a project with the same name was deleted beforehand
• Fixed a bug where ci.data would get lost in the Alexa payload when a user answered a slot question

Deprecation Warning

Old CognigyScript syntax

With this release we are moving forward and dropping support for the very old CognigyScript syntax. We have introduced the new {{ }} syntax already with Cognigy.AI 3.0.0 and this should not impact most of our customers. Please still double-check your flows whether you are using any of the following:

• <cs>some script</cs>, replace it with {{ some script }}
• <cc>contextValue</cc>, replace it with {{ cc.contextValue }}
• <ci>text</ci>, replace it with {{ci.text}}

You might also have some weird combos of the above statements, e.g.:

• <cs>cc.value</cs>, replace it with {{cc.value}}.

The current syntax has a lot of benefits compared to the old one, is more readable and actually fixes security vulnerabilities.

Values Input Object

We added two new fiels to the Input Object:

• hashedIp: Contains the sha1 of the clients IP address
• flowName: The name of the flow the Input Object was generated for

Source property

We added a new source property to the output of various endpoints. This allows customers to understand the origin of messages.

Configurable Get Help

We added the ability to configure the URL source of our Get Help button. Customers with on-premise deployments of Cognigy.AI can e.g. add a link to an internal support-channel / helpdesk.

Thai NLU support (Beta)

We added Thai as a new language to our product. This language needs to be specifically activated on the infrastructure-level. It is currently in beta - we are happy to get feedback from our customers!

Lazy connections

The Webchat will now only establish a connection to our infrastructure when the .open() API was used.

3.3.2

Released: June 3rd, 2019

Features

Environment tags

We added the ability for customers to add labels to their on-prem installations. This can be achieved through setting the ENVIRONMENT_TAGS environment variable to a comma separated list of keywords. The keywords will be exposed in the Cognigy Input object during Flow runtime. The tags can e.g. be used for conditional branching based on e.g. your dev and prod environments for httpRequest nodes.

Contact Profiles creation API

We added the ability toc reate a new Contact Profile using our RESTful API. Contact Profiles get created automatically during Flow execution. The new API allows the creation of a profile in advance.

Clean RabbitMQ disconnect

All services will now properly shutdown when RabbitMQ gets unavailable during runtime. Cognigy services will no longer be in an undetermined state after a RabbitMQ restart.

Project wide search

We added the ability to search for project resources within the Project overview. This is especially handy if you deal with huge Cognigy.AI projects that contain a high number of resources such as Flows, Lexicons etc.

Intent editor role

We added a new user-role to our product that only allows read- and update-permissions for intents. This role is perfect for editors who will use the Intent Trainer to modify and update your Conversational AIs within Cognigy.AI.

Improvements

• Add full support to use a system web proxy for outgoing connections to Amazon services
• Allow the execution of Flows of a different language, please read our documentation https://docs.cognigy.com/docs/execute-flow
• Auto-generate Process Input fields based on the given label

• Improved scrolling behaviour of the Interaction Panel - it will now preserve its scrolling position if you e.g. open the settings tab
• Various Webchat improvements, see our Releases page on Github: https://github.com/Cognigy/WebchatWidget/releases
• Improved the visualization of Custom nodes within the Flow editor by swapping the title and module name - this improves readability
• Improved sorting within the speed dial when creating new Project resources
• Added the ability to create Portugese (Brazil) flows
• Improved Spanish and Japanese translations for our Cognigy UI
• Improved the false-positive rates of our NLU 2.0 and NLU 2.1 systems

3.3.1

Released: May 09, 2019

Features

MongoDB connection string

Add the ability to configure the connection string for MongoDB using a docker-swarm/kubernetes secret. This is a more secure procedure than setting connection related information using environment variables.

RabbitMQ connection string

Add the ability to configure the connection string which is used for RabbitMQ using a docker-swarm/kubernetes secret. This is a more secure way than relying on env variables to store those type of information.

Import/Export for secrets

We added the ability to import/export secrets. Secrets within our import/export packages are still fully encrypted in addition to the encryption of the package itself. This now allows you to be more flexible and e.g. migrate your important credentials and sensitive information from one to another installation.

Dialogflow NLU Connector V2

We added support for API version 2 for our Dialogflow NLU connector. This now finally allows customers to use the modern version of the Dialogflow NLU. We are still supporting the old V1 API.

Flow overview

Added flow parent id and flow version id to the flow overview page. These values are necessary for certain API requests and were not displayed until now.

Improvements

• Removed conversationId field from dashbot payload. Dashbot had issues with this field being send
• Added sessionId to output data for Webhook endpoint/channel
• Sorted Intent names within a case-nodes alphabetically
• Added CognigyScript support for executeFlow- & switchFlow-nodes version fields

Bugfixes

• Fixed a bug where CognigyScript could not be used in keyphrase tag within Keyphrase questions in Processes
• Fixed a bug where the original request was not available in ci.data.request for our Slack endpoint/channel
• Fixed a bug where the setting continueFlowAfterNegativeConfirmation could never be changed
• Fixed a bug where the user interface session would time out if multiple tabs are open
• Fixed a bug where the Endpoint version dropdown was sometimes not populated correctly
• Fixed a bug where the url field within httpRequest nodes was not trimmed
• Fixed a bug where a list item from a Facebook List (say-node) could not get deleted
• Fixed a bug where cp.profileId was not always populated on the first message
• Fixed a bug where a think-node within an executeFlow could cause issues.
• Fixed a bug where Japanese lexicon entries were sometimes not recognized correctly in sentences
• Fixed a bug where the Intent Trainer would display empty records

---

3.3.0

Released: April 12, 2019

Features

Chinese NLU

We added full support for Chinese NLU, meaning you can now build Flows in Chinese.

Spanish NLU Improvements

We improved our Spanish NLU, especially when handling accents in sentences.

NLU 2.1

We added a new NLU version that greatly improves intent detection and has better support for short utterances.

Single Sign-on

We added the ability to login into COGNIGY.AI and to create users via Single Sign-on (SAML 2.0).

Secure Login

We improved the seuciryt of our platfomr by blocking repeatingly failed login attempts.

Tokens

We introduced Tokens, which can be used in Flows and Processes as shortcuts for CognigyScript. Tokens can be defined from developers using the new Token Editor. Your business users can then re-use those Tokens wherever they could use CognigyScript in the past. If the required Tokens exist, coding is no longer required within the platform to generate dynamic content within e.g. Say-Nodes.

Rule Editor

The Rule Editor is a new way which can be used together with Tokens in order to define conditions for logic branching. The Rule Editor works within the Cognigy Flow Editor as well as the Process Editor. It greatly reduces the amount of Cognigy Script that needs to be composed in order to support conditionals within your business logic.

Process Action Inputs / Outputs

In order to improve the workflow with Action-Flows within the Process Editor, we implemented the concept of Action Inputs/Outputs. Developers building an Action Flow can now define that those special Flows need certain Inputs to work properly. The Process Editor will re-use these information and render input-fields within the Process Editor. Furthermore, Cognigy will generate Tokens for your Action Flows and make them available within the Process Editor.

Custom Modules for Everyone

We changed the way how we execute Custom Modules, so that the execution of unsafe code is no longer a problem for the whole platforms stability. Thus allowing any developer to upload and test their Custom Modules without going through our review pipeline.

New Webchat (2.0)

Our Webchat was completely rewritten. The first iteration of the Webchat was already used by a vast majority of our customers. The new iteration of the Webchat is written in modern React and has a fully documented plugin architecture, which allows you to extend it.

We also introduced a new Date-Picker which uses the new Webchats plugin architecture and comes in a completely refresh design. There is even a new Flow-Node which let's you ask for dates in a new way.

Translated UI

We now have a fully translated UI in English, German, Japanese and Spanish - more languages to come in the future.

Blind Mode

More and more customers implement Conversational AIs dealing with sensitive information from users. In order to support the processing of sensitive data through Cognigy we introduced a new Flow Node and functionality within our software: The so-called blind-mode. This mode can either be activated through a Flow Node or through a setting within your Endpoints. Once activated. COGNIGY.AI will no longer store sensitive information such as the users text within system logfiles and analytics-data.

Intent Dropdown in Case Nodes

One of the most requested small features for 3.3.0 was a simple one and it landed within this release: If you now create a Switch-Node and select Intent from the dropdown, you will now be able to create Case-Nodes which contain a dropdown of all available Intents! You can still have a Text-Field available.

Settings Tab for some Flow Nodes

In order to remove some confusion from some of our Flow Nodes, we extracted certain settings and created separate Tabs within those Flow Nodes. Once candidate e.g. was the YN-Question-Node. It had certain settings in the "Default" tab which were actually used for all channel-outputs.

Bugfixes

• Fixed a bug where the Send Email Node couldn't send emails to multiple addresses
• Fixed a bug where out-of-range dates were recognized (e.g. 31st of August)
• Fixed a bug where yesterdays were not recognized as a date.
• Fixed a bug where CognigyScript didn't work in default replies
• Fixed a bug where the $push operator couldn't be used in the MongoDB Nodes
• Fixed a bug where the Regex slot filler did not work properly
• Fixed a bug where Lexicon synonyms where not trimmed on ipmort

• Fixed a bug where CognigyScript didn't work in Case Nodes
• Fixed a bug where the Flow search crashed in rare scenarios
• Fixed a bug where Custom Modules couldn't be executed in attached Flows
• Fixed a bug where additional confirmation words couldn't be more than one word
• Fixed a bug where the Intent training status would be incorrect

Deprecation warning

---

3.2.5

Released: March 14th, 2019

Features

Welcome message for the demo environment

---

3.2.4

Released: February 27th, 2019

Features

Timestamps for messages within Contact Profiles

We added timestamps on top of each message within the Contact Profile view. This helps to understand when individual messages got composed.

Healthchecks for NLU

We added Docker healthchecks and implemented the necessary changes for healthchecks to work. Orchestrators such as Docker Swarm or Kubernetes can use these healthchecks to validate whether services are already fully initialized after starting - or still fully functional after running for a while. In case a healthcheck fails, the orchestrator will kill the container and create a new copy of it.

Train Intents

We changed the behaviour of the train intents button so the button can always be clicked. In case COGNIGY.AI is already training a model for a Flow, an appropriate error will get displayed.

Intent Trainer adjustments

We introduced the Intent Trainer months ago to help our customers to refine their bots during they are online. We realised though, that the combination between saving and training intents was quite bad and lead to bad performance related to longer training times.

We therefore separated the functionality to store modifications within the Intent Trainer and to train intents later on. This goes hand-in-hand with the Train Intents modification described above.

Facebook page subscriptions

When COGNIGY.AI is used together with the Facebook messenger platform, a page needs to get created with subscriptions. Facebook supports a wide variety of different subscriptions, such as message, message postback, message read and others.

The only relevant subscriptions for COGNIGY.AI are message and message postback subscriptions. We have documentation in place describing the process of how to create a messenger endpoint properly. In case users added more subscriptions than the ones mentioned above (e.g. message read subscription), you could easily create an endless-loop of events.

We therefore improved the checks in our endpoint, so we only allow the supported subscriptions and log appropriate errors in case other subscriptions are used.

Japanese NLU

We improved our Japanese NLU system. This also improves the way how we handle keyphrases.

Rights Management

We improved the rights management for our UI system on various locations within our product. The API did already use the correct roles to deny certain modifications - but the UI did still render some input methods / buttons etc. We improved the rights management to make it more streamlined compared to our API.

UI language

We improved support for the Japanese language within our UI and added Spanish as a new language for our UI! We are happy to retrieve feedback from native speakers.

Google certificate

Google changed their certificate which is used to sign requests used for google account linking. We implemented the new certificate to guarantee, that our support for Google Actions is still working properly.

Bugfixes

• Fixed a bug where a new tag within the Lexicon Editor would not give users the chance to directly use this new tag within example sentences using the [[-bracket notation. They had to reload the Flow Editor first.
