2.0.1 - OpenAI Assistant history order fix and Vite security fixes

This is a quick patch release that addresses a bug in OpenAI Assistants where upon adding thread_id and load_thread_history properties would display the thread chat history in the wrong order. This has now been fixed.

Additionally, when users have been recently installing deep-chat or the deep-chat-react packages with npm, they would see 4 new security alerts in the console. These were not serious nor were they causing any issues with Deep Chat's functionality, however for good measure and to not alert our users, the dependencies that were causing these alerts have now been updated.

As always, huge thankyou to our sponsors!

2.0.0 - API changes, new features, improvements and bug fixes

The long awaited release of Deep Chat 2.0 is finally here!

This release features a number of critical API changes, addition of multiple new features, improvements on the existing ones and a multitude of bug fixes. This would not have been made possible without the continuous support of our open source community and their eagerness to create the best AI chat experience for all! We hope that this version will make it easier for new and existing developers to embed Deep Chat into their website and most that their users would have the best possible chat experience.

API changes:

• request has been renamed to connect
• stream property has been moved to connect
• InitialMessages property has been renamed to history
• onNewMessage event has been renamed to onMessage. The isInitial property that is passed in the event body has been renamed to isHitory. When listening to event emission from the element, the new-message event name has been changed to message
• request property in FilesServiceConfig interface has been renamed to connect

New features:

• adding a new addMessage method which is used to programmatically add new messages into the chat.
• adding a new setPlaceholderText method which is used to programmatically set the input's placeholder text.
• the speechToText interface now has three new properties; stopAfterSubmit which is used to control whether the recording stops after user has submitted a message, submitAfterSilence which controls if a message is automatically submitted after a period of silence and events which is used to listen to events emitted by interactions with speech.
• the openAI interface has been updated to reflect new features provided by the Open AI API.

UX improvements and multiple bug fixes:
When using the new Deep Chat component, you will notice multiple quality of life improvements, such as the ability to have line breaks for the outgoing user messages, better representation for uploaded files in the chat and many other benefits. This has all been realised and developed through consistent feedback from our Open Source community. Please checkout the issues section of our repo to find out how they were implemented.

Switching from v1 to v2:

All of the mentioned API changes are backwards compatible! So don't worry about having to update your configuration when switching to this version from a previous one. The browser console will also display warnings for properties that have been deprecated to help you switch to the new ones, however they can be ignored if they are not useful. If you are using TypeScript - the transition to the new version may introduce a couple of warnings in your build environment, they can be ignored if you want to keep using the old properties.

Thankyou to our sponsors!

• OpenAI Chat responses for functions can now be streamed.
• As well as responding with text or html in streams, you can now also respond with files.

Big thankyou to @eljefedelrodeodeljefe for sponsoring the project!

1.4.10 - create OpenAI Assistants and more

This release includes the following updates:

• Create a new OpenAI Assistant by emitting the assistant_id property in the Assistant object and control the its details via newAsssistant object.
• When the onComponentRender event is called, it now also passes the Deep Chat component reference. Be careful not to causes infinite event recursion if you assign new properties to the reference.
• webModel now supports new RedPajama and TinyLlama models.
• Other security and refactoring updates.

Huge shoutout to matthiasamberg for sponsoring the project!! 🎉 🎉

1.4.7 - Web Model

This release introduces a big new feature - the ability to use llm models entirely on the browser. You can read more about this in the webModel section.

Other updates:

• Images defined as base64 can now be downloaded by clicking on them
• OpenAI Assistants can now handle images and produce csv and pdf files
• The intro panel is not displayed when no valid connection values are configured
• Better parsing and responseInterceptor editing capabilities for stream
• Other small bug fixes

1.4.6 - generic enhancements and bug fixes

This release contains a series of generic enhancements and multiple bug fixes:

Enhancements:

• Ability to use the responseInterceptor for stream responses.
• If request property is not set on the initial render, you are now able to set it on further renders.

Bug fixes:

• The events methods no longer trigger a re-render.
• Responses from a stream service no longer overwrites the user message.
• Setting the OpenAI Assistant key via the insert key view now sets the correct request header when sending new messages.

Others:

• addMessage method has been removed as it does not yield any direct benefit to Deep Chat component.

1.4.5 - request and streaming updates

This release contains multiple updates for connecting to direct and custom services:

1. You can now define a model for the OpenAI Images API.
2. There are multiple new optional properties that you can use for Cohere APIs.
3. StabilityAI API documentation has been updated.
4. onNewMessage event now includes the actual uploaded file's reference using the MessageFile object type.
5. Adding a new onError event that allows the parent app to monitor chat errors.

This update also includes streaming bug fixes and better console logging when the response format from the server is invalid.

1.4.4 - updating message streaming and addMessage method

This release comes bundled with multiple updates for chat message functionality:

• Introducing a new overwrite property which allows the contents of the new message to overwrite the previous message. This facilitates the capability to create status message bubbles and streaming will no longer require the response to contain incremental portions of the previous text.
• Stream functionality has also been updated to allow html content to streamed. Additionally, the stream simulation functionality now splits the incoming text by characters instead of words to allow Chinese characters to be streamed individually.
• The submitUserMessage method now uses a new argument type called UserMessage which is an object that accepts text and files.
• addMessage is a new method used to add messages into the chat. The use-case this is targeting is to eventually populate the chat history once it has been fetched after the chat has loaded.
• The request object has a new optional credentials property which will allow developers to configure what services the cookies can be sent to.

Deprecation:

• The "deep-chat-update-message" HTML Class has now be removed in favour of using the overwrite in responses.

This release also contains multiple bug fixes for streaming and html messages.

1.4.3 - chatStyle property

We are adding a new chatStyle property for setting the chat container styling. This property directly supplements the already existing style attribute which can only be set in the markup, hence chatStyle allows developers to set this property anywhere and it accepts a JSON object.

This release also contains some refactoring work for streaming.

1.4.2 - custom roles

Deep Chat now supports the use of custom roles in your messages. This is particularly useful if your server communicates with multiple agents or users and you want to uniquely represent their message bubbles in the chat. This can be customized using messageStyles, avatars and names properties.

This update also includes bug fixes for controlling the submit button when streaming and simulating a stream whilst using websockets.
