Fixed

• Fix missing heartbeat and leave REST API calls when the event engine is enabled and presenceTimeout or heartbeatInterval not set.

v9.3.1

March 25 2025

Fixed

• Fix issue because of which channels and groups aggregated inside PubNub client state objects and didn't clean up properly on unsubscribe / invalidate.

v9.3.0

March 20 2025

Added

• Remove minimum limit for presence timeout (was 20 seconds) to make it possible specify shorter intervals.

Fixed

v9.2.0

March 19 2025

Added

• On pagehide without bfcache client on page will send terminate to Shared Worker for early long-poll request termination and leave request sending (if configured).

Fixed

• Fix an issue with the client's state update in Shared Worker caused by -pnpres suffixed entries being removed from heartbeat / leave request channels and groups.

v9.1.0

March 13 2025

Added

• SubscriptionSet will re-add listener every time when Subscription or SubscriptionSet added to it - this will let receive updates from newly added subscribe capable objects.

Fixed

• Fix issue because of errors returned by fetch taken from iframe (to protect against monkey-patching by APM packages) was't handled as Error.

Modified

• Use access token (auth key) content instead of base64 encoded token to identify PubNub clients, which can be used for requests aggregation.

v9.0.0

March 10 2025

Added

• BREAKING CHANGES: SubscriptionSet will subscribe / unsubscribe added / removed Subscription or SubscriptionSet objects if the set itself already subscribed.

Fixed

• Fix issue because of which throttle didn't consider difference in client settings (throttled only by user ID and subscribe key, which is not enough).
• With the fix, smart heartbeat as feature has been added to the SDK, and it is disabled by default.

v8.10.0

March 06 2025

Added

• Add useSmartHeartbeat configuration option which allows ignoring implicit heartbeat (with successful subscribe response) and keep sending heartbeat calls with fixed intervals.
• subscriptionWorkerOfflineClientsCheckInterval configuration option can be used to configure the interval at which “offline” PubNub clients (when tab closed) detection will be done.
• subscriptionWorkerUnsubscribeOfflineClients configuration option can be used to force unsubscribe (presence leave) for “offline” PubNub clients (when tab closed).
