JULY 2026

This month's update ships a redesigned default theme with multi-format theme files, brings the Data API to Flutter, and adds locale-aware app custom fields for multilingual email notifications, in addition to smaller updated and fixes.

Added

Flutter Data API

Version 0.1.0

• Added a Data API for Flutter. The TalkJS Core package (talkjs_core_flutter) lets you connect to your TalkJS chat as a user and read, subscribe to, and update your chat data. Android support is available today, iOS coming soon. See the announcement.

Components SDKs and Classic SDKs

• Added the option to define locale variants for any custom field in your app metadata, directly from your TalkJS dashboard. With localized custom fields, you can automatically set the correct language version of a custom field based on the user's locale. Localized custom fields are especially useful for localizing email themes, including subject line and body text. Learn more.

Components SDKs

Version 0.3.0

• Added a baseTheme prop to the Chatbox, Conversation list and Inbox components.
• Added Typescript, JSX and TSX versions of the themes, alongside the JS version that was already available. This gives you more flexibility to choose the format that best matches your setup.

Version 0.2.3

• Made various changes to the API related to search functionality: 

  • Added a searchQuery: string prop to ChatHeaderProps and ChatSearchBoxProps.
  • Added a new ChatboxController.setSearchQuery(query: string) method.

Changed

Components SDKs

Version 0.3.0

• Breaking change: Redesigned the default theme for a fresh, more modern look. The previous version of the default theme is now available separately as the classic theme. To upgrade while keeping your current look and feel, follow the upgrade guide. See the full announcement.

Version 0.2.4

• Changed the way we build theme files. If you have copied one or more components from our default theme, follow these instructions to apply the differences between 0.2.3 and 0.2.4.

Version 0.2.3

• Made the logic for the onChange event of SearchInput in ChatSearchBox internal.
• Made changes to the ChatHeader, ChatSearchBox and GlobalSearchBox theme files. Compare theme versions 0.2.2 and 0.2.3.

Version 0.2.2

• Improved how icons are included, for a much smaller bundle size.

Kotlin Data API (@core)

Version 0.2.0

• Lowered the minimum supported Android SDK to 21, extending compatibility to older Android devices.
• Breaking change: Refactored the API to remove several params classes (CreateUserParams, CreateConversationParams, CreateParticipantParams, TalkSessionOptions, SendTextMessageParams, SendMessageParams, EditTextMessageParams, EditMessageParams, SetUserParams, SetConversationParams, and SetParticipantParams) in favor of named parameters.

Fixed

React Native SDK

• Fixed an issue where, under certain conditions, voice messages would end up being 0 bytes.

Security

• Fixed a security vulnerability which, under certain conditions, would let a user mark another user’s conversation as read or unread.
