v10.0.0-rc.7

10.0.0-rc.7 (2026-08-21)

⚠ BREAKING CHANGES

• client.instanceConfigurationService is replaced by client.config,
  and the exported class InstanceConfigurationService is renamed to
  InstanceConfigurationRegistry.
• client.setInstanceConfigurationFunction() is removed. Register
  setup functions with client.config.setSetupFunction(key, fn).
  client.setMessageComposerSetupFunction() is unchanged.
• the per-class setup types are replaced by generic ones keyed by
  instance. Removed: ChannelSetupFunction, ChannelSetupState,
  ChannelTearDownFunction, MessageComposerSetupFunction, MessageComposerSetupState,
  MessageComposerTearDownFunction, StreamChatSetupFunction, StreamChatSetupState,
  StreamChatTearDownFunction, ThreadSetupFunction, ThreadSetupState,
  ThreadTearDownFunction, SetInstanceConfigurationFunctions,
  SetInstanceConfigurationServiceStates and SetupFnOf. Use InstanceSetupFunction,
  InstanceSetupState, InstanceSetupTearDownFunction and InstanceSetupKey.
• ChannelInstanceConfig is renamed to ChannelConfig and
  ThreadInstanceConfig to ThreadConfig.
• Channel.getConfig() is removed. Read the server's channel-type
  configuration from channel.serverConfig, or the resolved configuration from
  channel.config.
• client.configs is renamed to client.channelServerConfigs and
  client.configsStore to client.channelServerConfigsStore. Keys are still cids, so
  lookups translate directly. Prefer channel.serverConfig.
• channel.config.commands is renamed to
  channel.config.availableCommands. The server owns the list, so it is read-only and
  absent from the declarative configuration tree.
• applyCommandValidatorOverride is no longer exported. Command
  validation is configured through the composer's configuration.
• MessageComposerConfig gains a required polls;
  AttachmentManagerConfig gains required enabled and customCdn;
  LocationComposerConfig gains a required minShareDurationMs. A config object
  built literally must supply them.
• linkPreviews.enabled now defaults to true, where it defaulted to
  false. It is ANDed with the channel type's url_enrichment, so true means "no
  opinion, let the server decide"; the old default double-gated the feature and kept it
  off even where the server had enabled it.
• server flags gate the features they describe, ANDed with the
  registered value rather than the client value winning: typingEvents with
  typing_events, readEvents with read_events, attachments with uploads,
  polls with polls, location with shared_locations, and linkPreviews with
  url_enrichment. Code that set a flag to true and assumed it took effect may now
  find the feature off.
• setters no longer discard a write when the server is masking the
  field. Previously the setter compared against the effective value, so the write was
  dropped and the earlier request was honoured once the server relented. Affects
  linkPreviewsManager.enabled, textComposer.enabled, textComposer.maxLengthOnEdit,
  textComposer.maxLengthOnSend and attachmentManager.maxNumberOfFilesPerMessage.

Features

• add instance configuration service (#1831) (434966c)
• channel state migration (#1834) (9876add)

v10.0.0-rc.6

10.0.0-rc.6 (2026-08-21)

⚠ BREAKING CHANGES

• remove hand-written types and API wrappers (#1836)
• i18n: Streami18n.init() now rejects when i18next fails to
  initialize, where it previously logged and resolved. Callers that ignore
  the returned promise will see an unhandled rejection. The instance
  remains usable in its degraded English form either way.
  Streami18n.brand is removed; nothing in either UI SDK read it, and a
  custom integration that recognized instances through it should compare
  against its own marker or accept the instance it was handed.

Bug Fixes

• i18n: reject from init() and drop the Streami18n brand static (#1839) (67bb1c7)
