As part of our planned deprecation of our oldest wire protocol version, connections which do not specifying a protocol version, which were previously served that oldest one, will now be served the latest. This only affects you if you have written your own custom client against our realtime wire protocol, and are not requesting a particular protocol version. If you are doing this and want a stable…
Client Library SDK Fix Privacy manifest changes The SDK's privacy manifest (PrivacyInfo.xcprivacy) no longer marks the Device ID data type as used for tracking: NSPrivacyCollectedDataTypeTracking is now false. The Device ID is a random UUID that the SDK generates and sends to Ably only to register the device for push notifications and to subscribe it to push channels. That is app functionality, no…
A few small behaviour changes we're rolling out: Unbatched webhooks can now be signed, just like batched ones. Filtered subscriptions will soon no longer require a [filter]-qualified capability; simple message-subscribe will do. Permission to subscribe to any arbitrary subset of messages on a channel and permission to subscribe to all messages on a channel are logically equivalent, so there wasn't…
New feature Enabling features (such as message persistence or server-side batching) on Ably channels involves configuring a channel rule. Previously, channel rules could only be applied to a specified namespace: configuring a rule to enable persistence for the foo namespace would enable it for the channel literally called foo, as well as any channel starting with foo:, such as foo:bar or foo:bar:b…
Client Library SDK Improvement This release adds a simplified streaming layer, so you can stream an agent's output over an Ably channel without handing your conversation state to the SDK. Adopting AI Transport no longer means adopting the conversation tree first. The main changes: Streaming layer: a client transport and an agent transport give you run and step framing, cancellation and steering ov…
Client Library SDK Improvement This release contains various improvements and stability fixes to the core PubSub SDK. Most notably: Use PING protocol messages for browsers, React Native and NativeScript. Liveness is now confirmed by the SDK itself rather than by the underlying WebSocket, which can keep answering ping frames while the app is suspended Add PresenceMessage.memberKey - the key that un…
Client Library SDK Fix Client Library SDK Improvement This release includes important bug fixes that affect the SDKs reconnection behaviour when the connection between client and server goes quiet. Previously the SDK would incorrectly wait up to 120 seconds since last activity - this is now reduced to ~25 seconds. A significant number of peripheral fixes are also included to improve stability and…
Client Library SDK Improvement LiveObjects The LiveObjects plugin is no longer experimental! 🎉 It’s now production-ready for applications that need to manage complex, fast-changing state across AI agents, live configurations, and collaborative experiences—with state synchronization across multiple platforms. Here's what it provides: Path-based access: Navigate and manipulate deeply nested LiveMap…
Improvement This release brings a large number of improvements and stability fixes, including new data sources for querying apps, keys, namespaces and queues, moderation rules as resources, and a tool that generates config from an account you built by hand. New Data sources for apps, keys, namespaces and queues, in singular and plural form, plus ably_me for the account and token Moderation rules:…
Client Library SDK Improvement LiveObjects The AblyLiveObjects plugin is no longer experimental as of this release, which also makes breaking changes to its API — see below before upgrading. For Pub/Sub (Ably) users the only change is a fix to annotation encoding on channels whose cipher options were changed after creation. Breaking LiveObjects API changes PrimitivePathObject gains six per-case va…
Client Library SDK Improvement Ably-js 2.28.0 is released, adding end to end encryption for annotation data payloads. These were previously not covered by e2e encryption to allow serverside summaries of certain aggregation types, but those types have been removed in favour of ones which store aggregatable information outside of the data payload, so we can now enable e2e encryption on annotation pa…
Client Library SDK Improvement This release introduces a Temporal plugin that lets you run a durable agent on Temporal without hand-writing the run lifecycle yourself. It also adds support for Vercel AI SDK v7, so you can build on v6 or v7. The main changes: Temporal plugin: register one plugin on your Temporal worker and the activities that frame an agent turn come with it. Your workflow wraps a…
Fix We will shortly be correcting an incongruency in our capabilities definitions. Currently, a capability for a resource such as ns:* also permits operations on the bare channel ns. While this behaviour matches how channel rules work (a channel rule for "ns" will apply to both the literal channel "ns" and all channels that start with "ns:"), and can be a useful shortcut, it's not remotely intuiti…
Client Library SDK Improvement Managing complex, fast-changing state for AI agents, live configs and collaborative apps just got much cleaner with new LiveObjects path based API. Here's what it unlocks: Path-based access: Navigate and manipulate deeply nested LiveMap and LiveCounter structures using simple paths. You no longer need to manage explicit object instances to read or update nested data.…
Client Library SDK Improvement This release fixes clients failing to connect on networks whose proxies reject WebSockets, and moves connection continuity decisions from the client to Ably. WebSocket fallback: when the WebSocket handshake is rejected outright, for example by a proxy answering with a 403, the client now falls back to HTTP polling instead of reporting that it cannot connect and retry…
Client Library SDK Improvement This release adds support for the OpenAI Responses API. If your agent talks to the Responses API directly, you can now stream it over an Ably channel, with client-executed tools and human tool approvals included. The main changes: OpenAI Responses codec: a new @ably/ai-transport/openai entry point streams the OpenAI Responses API over a session (assistant text, refus…
Client Library SDK Improvement This release adds a dedicated React hook for subscribing to LiveObjects state, plus push token rotation support for React Native. useObject React hook: the new useObject hook subscribes a component to LiveObjects state on a channel. Pass an optional selector to navigate to any node of the object tree. The hook returns a reactive, render-stable snapshot of that node (…
Client Library SDK Improvement This release adds mid-run steering, so a user can change direction while the agent is still working. The client sends a follow-up prompt into the run that is already streaming, and the agent folds it in and carries on, without cancelling the run or starting a new one. The main changes: Mid-run steering: call run.steer() with a follow-up message and the agent picks it…
Client Library SDK Improvement This release adds push notification support for React Native apps through a dedicated plugin. React Native push notifications: the new ably/react-native-push plugin activates a React Native device as a target for push notifications. Your app supplies its own storage and token acquisition (typically @react-native-async-storage/async-storage and @react-native-firebase/…
Client Library SDK Improvement Managing complex, fast-changing state for AI agents, live configs and collaborative apps just got much cleaner with new LiveObjects path based API. Here's what it unlocks: Path-based access: Navigate and manipulate deeply nested LiveMap and LiveCounter structures using simple paths. You no longer need to manage explicit object instances to read or update nested data.…
Client Library SDK Improvement This release adds first-class support for running AI agents inside durable execution frameworks such as Temporal and Vercel's Workflow Development Kit, so a single agent turn can survive process restarts and retries. The main changes: Durable execution: a new Step primitive is the re-attemptable unit of an agent's output. When a workflow engine runs each turn as a se…
Client Library SDK Improvement This release adds external data hydration, so an app that keeps its own message store can seed a conversation from that store and reconcile only what it is missing from the Ably channel, instead of replaying the whole history. The main changes: External data hydration: a new View.loadUntil() primitive and the useMessagesWithSeed React hook page channel history back t…
Client Library SDK Fix Pub/Sub Fixes an issue where the locally stored Ably push notification registration state could not be loaded before the device first unlock after a reboot.
Client Library SDK Improvement This release makes codecs much simpler to author and lets you layer Ably Pub/Sub Presence and LiveObjects onto the same session as your AI stream. The main changes: Declarative codec authoring: defining or customising a codec is now declarative. You describe each wire event once and defineCodec derives both the encode and decode sides, instead of hand-writing and han…
Client Library SDK Improvement Client Library SDK Fix Version 2.23.0 of the JS Client Library has been released. The React channel hooks can now infer the channel from the nearest ChannelProvider, letting you omit the channelName argument and use new listener-only and callback-only overloads of the library's React hooks. This release also fixes a presence bug where automatic re-enter could fail wi…
LiveObjects Improvement We’ve updated the dashboard to give you more visibility into the LiveObjects you create and maintain on your channels. This includes two main items: A realtime stream of each object operation as they occur. A visualisation of all LiveObjects on the channel that is updated in realtime. This enables you to quickly see exactly which objects exist on a channel and their associa…
Client Library SDK Fix Version 2.22.1 of the JS Client Library has been released. This patch release fixes the deprecated v1 callback API overloads, which were declared with a never return type in 2.22.0. That return type broke mock assignment, making it impossible to stub or mock these methods in tests. The return type is now void, restoring compatibility for code that mocks the deprecated v1 cal…
Client Library SDK Improvement Version 0.2.0 of the Ably AI Transport JS SDK has been released. This release gives a clearer session/run API and more robust support for branching conversations and human-in-the-loop handoff. The main changes: Session/run model: the transport/turn API is renamed to session/run (createClientSession / createAgentSession, ClientSession / AgentSession, ActiveRun, Run.pi…
Client Library SDK Improvement Version 2.22.0 of the JS Client Library has been released. This release makes the agent channel option additive in React hooks, so custom agents are now appended alongside the React Hooks agent rather than replacing it. It also changes channels.release() to implicitly detach the channel instead of throwing on an unexpected channel state, adds the missing RestAnnotati…
Client Library SDK Improvement New feature Version 1.4.0 of the Chat JS SDK has been released. This release adds support for idempotent REST publishing and the ability to fetch message version history via getVersions() exposed on the Messages class. For the full changelog, please visit the Github release page.
