JUNE 2026

This month's update brings real-time conversation filtering to the Data API, Components SDK, and Classic SDK, and refreshes the Components SDK's default icon set. We've also deprecated an unsupported field and fixed a few bugs.

Added

Components SDKs

Version 0.2.0

• Added a new Icon system component for rendering icons.

Version 0.1.11

• Added a new conversationFilter?: ConversationFilter prop to the ConversationList and Inbox components, which lets you display only the conversations matching the given filter. More on real-time conversation filtering.

JavaScript Data API (@talkjs/core)

Version 1.10.0

• Added support for filtering the list of conversations in TalkSession.subscribeConversations. Added filter types, ConversationFilter, SimpleConversationFilter, CompoundFilter, StringFilter, NumberFilter, and CustomFilter. More on real-time conversation filtering.

Classic SDKs

Version 0.46.0

Version 0.1.11

• Fixed an issue where the voice recording functionality wouldn't work correctly on old versions of Safari.

MAY 2026

This month's update brings message and conversation search to the Components SDK, lets you subscribe to live emoji reactions and see who reacted to a message, and adds a couple of requested improvements to React Native. We've also renamed a few APIs for clarity and fixed a handful of bugs.

Added

Components SDKs

Version 0.1.9

• Added a new useReactions() hook which lets you lazy-load up to 10 users that first sent a specified emoji reaction on a given message. More on real-time message reactions.
• Added a special t-tooltip-text attribute which lets you display a tooltip on an element when hovered. Currently used for displaying who left a given emoji reaction.

Version 0.1.8

• Added support for message search and conversation search, which is available on the Growth plan and higher. This includes adding new GlobalSearchBox, GlobalSearchResultHeader, and GlobalSearchResultItem theme components.
• Added support for in-conversation message search, which is available on Growth plan and higher.
• Added the Highlightable system component to mark text which can be highlighted. These highlights can appear from other chat features such as in-conversation search.
• Added the SearchInput system component which is used to initiate a search.

JavaScript Data API (@talkjs/core)

Version 1.9.0

• Added ReactionsRef.subscribe, which subscribes to the list of users who added a specific reaction onto a message. Also added SingleReactionSnapshot, ReactionsSubscription, and ReactionsActiveState. More on real-time message reactions.
• Added ReactionRef.getFirstReactions, which is a simpler way to just fetch the first page of users who reacted with an emoji.

React Native

Version 0.17.0

• Added support for SendMessageEvent.override. This function allows you to modify the contents of the message or its metadata before the message is sent.
• Added smallIcon as a property to AndroidSettings. This allows you to change the small icon on Android notifications.

Changed

Components SDKs

Version 0.1.10

• Made changes to the CompactMessageContent, ConversationListItem, Message, and MessageField theme files. Compare theme versions 0.1.9 and 0.1.10.

Version 0.1.9

• Requires a @talkjs/core peer dependency version 1.9.0 or higher.
• Adjusted the reaction count to use tabular digits, meaning each digit takes up the same amount of space.
• Made changes to the Message and NoConversationSelected theme files. Compare theme versions 0.1.8 and 0.1.9.

Version 0.1.8

• Made the NoConversationsSelected theme component display ‘Select a conversation’ by default instead of displaying nothing.
• Made slight UI adjustments for error states that show up when a conversation can't be found or something else goes wrong.
• Changed various theme files. Compare theme versions 0.1.6 and 0.1.8 (theme versions 0.1.7 and 0.1.8 are identical).

JavaScript Data API (@talkjs/core)

Version 1.9.0

• Renamed multiple classes and methods for clarification. Old names remain available as aliases for backwards compatibility:

  • ReactionRef to ReactionsRef
  • MessageRef.reaction to MessageRef.reactions
  • ReactionSnapshot to ReactionsSummarySnapshot

Classic SDKs

Version 0.45.1

• Renamed hasUnreadMessages to isUnread in conversation predicates, to make it clearer that this includes conversations that are manually marked as unread. hasUnreadMessages will continue to be supported as an alias for back-compatibility.

REST API

• The unreadsOnly query parameter now simply sets isUnread: true in the filter rather than adding to the query, simplifying the query logic.

React Native 

Version 0.17.0

• Updated dependencies.

Fixed

Components SDKs

Version 0.1.10

• Fixed an issue where the send or voice recorder button would be visible despite the user having read-only access to a conversation.
• Fixed an issue where lists in ConversationListItem, ReplyBar and ReferencedMessage components didn't display properly on Safari.

  Version 0.1.9

• Fixed a bug that prevented the emoji picker from being dismissed by tapping outside of it on mobile devices.

  Version 0.1.8

• Fixed an issue where the waveform inside the AudioPlayer would cause a layout shift during the initial load.

JavaScript Data API (@talkjs/core)

Version 1.9.1

• Fixed a bug where it was assumed that all ‘participant edited’ events were about the current user. This meant if you did ConversationRef.subscribe and ConversationRef.subscribeParticipants at the same time, changes to any participant's access or notify triggered the conversation subscription to emit as if your access or notify had changed.

React Native (@talkjs/expo)

Version 0.17.1

• Fixed an issue with dynamically importing @react-native-firebase/messaging when using versions 23.8.0 and above.

TalkJS monthly product update

APRIL 2026

This month's update brings you new building blocks for creating rich chat experiences, including an Inbox component and support for voice messages on the Components SDK. We’ve also streamlined message handling on the REST API, fixed some bugs and made performance improvements.

Highlight 

More flexible message filtering and imports in the REST API

The REST API now makes it easier to work with message data at scale. You can filter messages by message and sender attributes when fetching them, enabling more targeted queries or custom views.

We’ve also improved message imports. You can now import messages from non-participants, such as guests or people who’ve been removed from a conversation. In addition, we've simplified read status when importing messages. You no longer need to set readBy on every message; just import all messages, then set each participant's readUntil at the end.

Overview

Added

Components SDK

Version 0.1.6

• Added the Inbox (React) and t-inbox (Web Components) components, which combine a conversation list and chatbox into a single responsive layout.
• Added a VirtualMessage system component, which lets you show virtual (or ‘fake’) messages in the message list.
• Added support for conversation.welcomeMessages in the BeforeMessages theme component using virtual messages, to allow showing welcome messages.
• Added a NoConversationSelected theme component.

Version 0.1.5

• Added support for voice messages. Users can now record, preview, and send audio messages directly in the chat UI, with built-in waveform visualizations.
• Added a VoiceRecorder theme component that’s rendered during active voice recording.
• Added a RecordingPreview theme component that allows a user to preview the audio they’re just recorded.
• Added a Waveform system component that renders an audio waveform visualization.

Changed

Components SDK

Version 0.1.6

• Chatbox now supports the conversationId field to be null. When there’s no conversation selected, the new NoConversationSelected theme component is shown.
• Made various performance improvements, including reducing message re-rendering and ensuring smoother switching between conversations. 

• Made various theme updates (non-breaking changes):

  • ChatHeader can now optionally display a back button for responsive navigation when using an Inbox chat UI.
  • Added a t-status attribute in the Message component to ensure that pending messages keep a stable size during sending.
  • Added conversationId to the Message component’s common theme props, to reduce re-renders.
• Compare theme versions 0.1.5 and 0.1.6.

JavaScript Data API

• Emoji reactions are now ordered by the time they were first added, instead of alphabetically.

REST API 

• App-scoped tokens are now called admin tokens, to clarify that these are sensitive tokens intended for admin use only. You cannot include a 'sub' claim (user id) in the payload of an admin token.

Deprecated

REST API

• readBy is now optional and deprecated. We recommend importing messages without setting readBy, then setting readUntil on each participant at the end.

Fixed

Components SDK

Version 0.1.6

• Fixed an issue where image previews would sometimes blink when sending messages.
• Improved the reliability of the ‘New messages’ marker.

Version 0.1.5:

• Fixed an iOS 18 issue where, under some conditions, playback of voice recordings could break the UI.
• Fixed an issue where the audio player speed popover would be partially hidden.
• Fixed an issue where the message field placeholder text would overlap with sending icons in narrow chatboxes.

Version 0.1.4:

• Fixed an issue where loading older messages could cause the scroll position to jump.

Classic SDKs

• Fixed a bug that would cause inconsistent behavior when loading older conversations after changing feed filters.
• Improved error messaging when a user attempts to join a non-existent conversation as a guest.
• Fixed an issue where notifications weren’t sent for messages sent by guests or participants removed from the conversation.

This update from TalkJS brings a native Kotlin Data API for Android, improvements to how subscriptions work in the JavaScript Data API, and a range of stability and security fixes across SDKs.

Highlight

Kotlin Data API for Android

You can now use the TalkJS Kotlin Data API: a native, real-time SDK for connecting to TalkJS from Kotlin applications, including Android and other JVM environments. This makes it ideal for teams building fully custom chat UIs in native Android apps without relying on WebViews.

The Data API lets your app connect as a specific user and read, subscribe to, and update chat data directly. It’s designed for modern mobile development and gives you full control over how chat is rendered in your application. 

It’s now officially published to Maven Central as com.talkjs:core.

Learn more.

Overview

Changed

JavaScript Data API

• Version 1.8.1: 

  • Subscriptions now operate independently, so calling loadMore on one subscription now no longer affects other subscriptions.
  • While a loadMore request is in progress, you can now call loadMore again with a higher count to fetch a larger page.

Fixed

JavaScript Data API

• Version 1.8.3: Fixed an issue where year ranges such as 2010-2018 were incorrectly treated as phone numbers when content suppression was enabled.
• Version 1.8.2: Fixed Uncaught (in promise) errors being logged, especially when using React Strict Mode.

Components SDK

• Version 0.1.3: Fixed an issue where emoji and mention suggestions could fail in production builds using Next.js 15 with SWC minification.
• Version 0.1.2: Fixed a bug where the reaction picker would sometimes clip into the edge of the chatbox.

Flutter SDK

• Version 0.17.5: Fixed crashes on iOS 26 when evaluating JavaScript before the WebView is loaded.
• Version 0.17.4: Fixed a crash on iOS 26.
• Version 0.17.3: Fixed a runtime type error when triggering onSelectConversation.
• Version 0.17.2: Fixed an issue where a params property was missing from ConversationActionEvent and MessageActionEvent.

Security

WordPress Plugin

• Version 0.1.16: Patched an XSS vulnerability in the admin settings page (CVE-2026-1055).

This update brings greater flexibility for customizing your message list, and a range of SDK improvements across web and mobile.

Highlight

Customize your message list layout

Take full control over how your message list is structured. With the Components SDK (v0.1.0), you can now customize the areas above, inside of, and below the message list using newly introduced theme components.

This version adds a MessageListHeader component rendered above the message list container, complementing the existing MessageListFooter below it. Inside the message list container itself, you can now use the BeforeMessages theme component (rendered before the first message) and the AfterMessages component (after the last message). 

Components inside the message list container scroll naturally along with messages, making it easy to add contextual UI elements such as system banners or onboarding hints. Existing functionality, such as typing indicators, now lives in AfterMessages, providing more flexibility for message list customization.

All of these are exposed as theme components, giving you fine-grained control over layout and styling without workarounds.

Overview

Added

Components SDK

• Version 0.1.1:
  • Added a Preact export to @talkjs/web-components, allowing you to make your theme stateful with useEffect, useState, and the like, using Preact.
  • Added a useParticipants(conversationId, limit) hook that components can use to subscribe to a list of participants in a conversation.
• Version 0.1.0: Added localizations for the emoji picker, including emoji data for multiple languages, allowing users to search for emoji using keywords in their native language.

JavaScript Data API

• Version 1.8.0: Added ParticipantRef.subscribe, which lets you subscribe to updates for a specific participant in a conversation. This can be useful, for example, to detect when a message sender has left a conversation.
• Version 1.7.0: Added support for full message and conversation search. Use Session.searchConversations() to search across a user's conversations, and Session.searchMessages() to search through messages across those conversations.

Flutter SDK

• Version 0.17.0: Added an onError property to Session, Chatbox, and ConversationList, allowing you to provide a handler that is called whenever the JavaScript SDK encounters an error.

Changed

Components SDK

• Version 0.1.1: Made changes to the ChatHeader, ConversationListItemProps, GroupChatImage, and Message theme files. Compare theme versions 0.1.0 and 0.1.1.
• Version 0.1.0:Breaking change: Changed how the message list footer is rendered. The MessageListFooter theme component is now rendered below the message list container and no longer scrolls with the message list. Typing indicators have been moved to the new AfterMessages component. If you’ve customized MessageListFooter, see the upgrade guide for required changes.

JavaScript Data API

• Version 1.8.0: Optimized TalkSession.uploadFile() and related upload methods to perform an initial validation (such as for file size and filename checks) before uploading. Previously, files were fully uploaded before an error was returned.
• Version 1.6.3:Ref objects now maintain referential integrity. Calling Session.conversation("123") multiple times returns the same ConversationRef instance, instead of creating new ones.
• Version 1.6.2:
  • Made locale in SetUserParams nullable. Setting locale to null means the user falls back to the default locale configured on the dashboard.
  • Improved performance when repeatedly calling ConversationRef.get().

Flutter SDK

• Version 0.17.0: Breaking change: Updated the minimum supported SDK versions: minimum Flutter SDK version is now 3.32.0, and minimum Dart SDK version is now 3.8.0.

Deprecated

Components SDK

• Version 0.1.1: Deprecated the common.participants theme prop. Added the new useParticipants() hook to use instead.

Fixed

Components SDK

• Version 0.1.1: Fixed a bug in @talkjs/web-components that prevented explicitly passing null to nullable props such as selectedConversationId.
• Version 0.1.0: Fixed an issue where the waveform of audio files sometimes wouldn’t appear in Safari 26.
• Version 0.0.36: Fixed an issue where the list of participants shown in the mentions dropdown could be incomplete.
• Version 0.0.35: Fixed a bug where drag-and-drop file sharing didn't respect the file sharing setting configured on the dashboard.
• Version 0.0.34: 
  • Fixed an issue where enabling React Strict Mode could cause the UI to load indefinitely.
  • Fixed an issue where upload previews for very tall images or videos could push the send button off-screen.

Flutter SDK

• Version 0.16.2:
  • Fixed a crash when building with Xcode 26.2 and deploying to iOS 26.2.
  • Fixed an issue where audio waveforms weren't generated until the user interacted with the audio on iOS 26.

JavaScript Classic SDK

• Fixed an issue where upload previews for very tall images or videos could push the send button off-screen.
• Fixed an issue where audio waveforms weren’t always rendered on Safari (both iOS and macOS).
• Fixed an issue where setHighlightedWords didn’t accept empty arrays. You can now pass an empty array to reset highlighted words without reloading the UI.
• Fixed an issue on mobile where the system media control panel didn’t correctly display the app’s name when playing audio or video.

New from TalkJS this month: powerful admin tools for managing conversations and moderating content, alongside accessibility improvements and other SDK updates.

Highlights

Admin conversation search on the TalkJS dashboard

Search through all conversations within your site or app, directly from your TalkJS dashboard. 

• Available on all plans: Filter conversations by their conversation ID.
• Growth plan: Filter conversations by conversation ID, subject, and custom search values.

Admin conversation search allows you to quickly find and audit conversations without having to export data or build custom tools.

Easier content suppression

Chat content moderation just got easier. You can now suppress unwanted content directly from your TalkJS dashboard by adding a list with forbidden words or phrases.

With a forbidden word list, there’s no need to create complex regexes to filter out unwanted content. Advanced users can still use custom suppression patterns if needed.

Overview

Added

• Components SDK (0.0.32): Added localization for error messages during file upload when the file is too big or has an unsupported extension.
• React Native SDK (0.16.0): Added onError prop to the Session component.
• REST API: Added a REST API endpoint to permanently delete a file attachment.

Changed

JavaScript Data API

Version 1.6.1

• Prevented switching to JWT authentication once connected to TalkJS servers. Your initial setToken or onNeedToken configuration must happen before the first requests, or before mounting any UI components.
• Optimized initial WebSocket connection to happen in parallel with fetching a token, to improve startup speed.

Version 1.6.2

• Made locale in SetUserParams nullable. Setting locale to null means the user falls back to the default locale set on the dashboard.
• Improved performance when repeatedly calling ConversationRef.get().

Components SDK

Version 0.0.31

This release includes breaking changes.

• Breaking change: Removed the @talkjs/react-components/theming and @talkjs/web-components/theming package entrypoints. All of their exports are now available from @talkjs/react-components and @talkjs/web-components directly. Follow the upgrade guide. 
• Breaking change: Made @talkjs/core a peer dependency of @talkjs/react-components and @talkjs/web-components. Follow the upgrade guide.
• Improved keyboard accessibility for the message actions menu and the emoji reactions button.

Version 0.0.32

• Added localized ARIA labels to tell assistive tools how to describe elements of the UI, localized to the current user's locale.
• Made various changes to the Message and MessageField theme files. Compare themes versions 0.0.31 and 0.0.32.

Classic JavaScript SDK

• Version 0.42.2: Made locale in SetUserParams nullable. Setting locale to null means the user will fall-back to the default locale set on the dashboard.
• Added localized ARIA labels to tell assistive tools how to describe elements of the UI, localized to the current user's locale.

Fixed

• JavaScript Data API (1.6.1): Fixed a bug where two authentication methods could be active at the same time, causing race conditions.
• Components SDK (0.0.32): Fixed a bug causing crashes when a user with a non-existent role mounts the UI.
• Components SDK (0.0.33): Fixed incompatibility with some build tools that caused the emoji picker to load forever.

Highlights

Action Buttons and Links in Components

You can now use Action Buttons and Action Links inside message content in TalkJS Components. These let you execute custom code in your chat. As such, they’re perfect for quick-response actions, such as polls, approving requests, or marking items as done. When a user clicks a button or link, it triggers an onMessageAction event. 

Support for HEIC and HEIF files

Users can now upload HEIC (High-Efficiency Image Codec) and HEIF (High Efficiency Image File) images. These files now display correctly throughout TalkJS, including in the chat, email notifications, and when sent via the REST API. HEIC/HEIF images offer high-quality, efficient compression and are increasingly used on iOS devices and modern cameras. With this update, users can share HEIC and HEIF images just like any other supported file type.

Overview of other changes

Added

• Components (0.0.29): Added support for content suppression.
• JavaScript Data API (1.6.0): Added TalkSession.setToken(token: string) which reauthenticates the session with a new token.
• JavaScript Data API (1.6.0): Added TalkSession.onNeedToken: () => void, which gets called whenever a new auth token is needed. To use refreshable auth tokens, set a callback that fetches a new auth token and passes it to setToken.
• Classic JavaScript SDK: Added support for programmatically jumping between search results. HighlightControls now exposes the methods jumpUp and jumpDown to navigate to the previous or next matching message.

Changed

• JavaScript Data API (1.6.0): Initial token fetch is now delayed until you actually use the session to send a request, rather than happening as soon as you call getTalkSession.

Deprecated

• JavaScript Data API (1.6.0): Deprecated token in getTalkSession. Use TalkSession.setToken instead.
• JavaScript Data API (1.6.0): Deprecated tokenFetcher in getTalkSession. Use TalkSession.onNeedToken instead.

Fixed

• Components (0.0.29): Fixed an issue where, under certain conditions, editing a message could cause an error.
• Components (0.0.30): Fixed a content suppression bug that could cause the chatbox to crash.
• Classic JavaScript SDK: Fixed an issue where scrolling to a long message showed the bottom instead of the top of that message.
• Classic JavaScript SDK: Fixed an issue where content suppression wouldn’t correctly suppress link previews.

This month’s update brings real-time emoji reactions to the JavaScript Data API, introduces the new TalkJS Support Bot, and includes important fixes and SDK improvements across platforms.

Highlights

Emoji reactions with the JavaScript Data API

You can now access and manage real-time emoji reaction data for any message using the JavaScript Data API. TalkJS Core 1.5.0 introduces two new objects: ReactionRef, created via MessageRef.reaction, and ReactionSnapshot, available through MessageSnapshot.reactions. These allow you to subscribe to live updates on emoji reactions, see how many reactions a message has, and add or remove reactions programmatically.

This update supports both Unicode and custom emoji, with a limit of 50 distinct emojis per message.

For implementation details, check out the documentation for:

• MessageRef.reaction
• MessageSnapshot.reactions
• ReactionSnapshot
• ReactionRef

24/7 TalkJS Support Bot

Building at 2:13 a.m.? We’ve got you covered. You can now get TalkJS support 24/7 with the new TalkJS Support Bot. Whether you’re integrating TalkJS into your app or fine-tuning your chat experience, the Support Bot can instantly help with product questions, troubleshooting, and setup guidance, even outside our regular office hours (CET).

Of course, our expert human support team is still here when you need them. If you’d like to talk to a person, just hit Talk to a human and a support engineer will pick things up from there.

Other changes

Added

• Added an endpoint to add or remove emoji reactions with the REST API.

Changed

• JavaScript SDK (0.41.1): Session.user, Session.conversation, ConversationRef.message, ConversationRef.participant, and MessageRef.reaction now all perform type validation on the argument and will throw an error if you use an invalid type or an empty string.
• JavaScript Data API (1.5.1): When passing markup text to ConversationRef.send, it now ignores formatted links, action buttons, action links. Previously it parsed those nodes and tried to send them, which caused an error because users don't have permission to send those nodes.
• JavaScript Data API (1.5.0): Session.user, Session.conversation, ConversationRef.message, ConversationRef.participant, and MessageRef.reaction now all perform type validation on the argument and will throw an error if you use an invalid type or an empty string.
• JavaScript Data API (1.4.2): Changed GenericFileBlock from subtype?: undefined to subtype?: never so that type narrowing works consistently when you check subtype === "".
• Flutter SDK (0.16.0) – Breaking change: Updated Firebase dependencies. This upgrades the Firebase iOS SDK version to 12.0.0 and the Firebase Android SDK version to 34.0.0.  As a result the minSdkVersion on Android is API Level 23 (Android 6.0) and the minimum iOS version supported is iOS 15. See the Firebase Android and iOS release notes for more information.

Fixed

• JavaScript SDK (0.41.1): Fixed a bug where MessageRef.get() would always set MessageSnapshot.referencedMessage to null.
• JavaScript Data API (1.5.0): Fixed a bug where MessageRef.get() would always set MessageSnapshot.referencedMessage to null.
• Flutter SDK: Fixed a bug where, on iOS, switching focus from one input field to another would cause the webview to shift downwards. Upgrade dependencies (flutter pub upgrade) for the update to take effect.
• Fixed an issue where users on iOS using Safari would have to double tap a link for that link to open.
