-Resumable streams: reconnect to an in-flight SSE **or NDJSON** response without
-re-running the provider.
-
-`toServerSentEventsResponse` and `toHttpResponse` both accept a
-`durability: { adapter, batch }` option. The adapter (`StreamDurability`)
-records every chunk to an ordered log before delivery and tags each event with
-an opaque, adapter-owned offset — an SSE `id:` line, or the `id` of an NDJSON
-`{ id, chunk }` envelope (NDJSON has no native event-id). A reconnect
-(`Last-Event-ID`) or an explicit `?offset` read replays strictly after that
-offset from the log — the lazy provider stream is never iterated on resume.
-Producers terminalize the log on cancellation and failure (`RUN_ERROR` append
-
-- `close()`) and on completion when the source stream emits its own terminal
-  event (`chat()` always does), so readers are never parked on a dead run.
-
-Two adapters ship: `memoryStream(request)` in `@tanstack/ai` (process-local,
-for development and tests) and the new `@tanstack/ai-durable-stream` package,
-a Durable Streams protocol adapter for production backends.
-
-For the `GET` handler that a reload or a second tab reconnects to,
-`resumeServerSentEventsResponse({ adapter })` and `resumeHttpResponse({ adapter })`
-replay a run straight from the durability log. They need no producer stream and
-return a 400 when the request carries no resume offset.
-
-On the client, all four HTTP adapters are now resumable — `fetchServerSentEvents`,
-`fetchHttpStream`, `xhrServerSentEvents`, and `xhrHttpStream`. Each tracks the
-per-event offset, auto-reconnects with `Last-Event-ID`, de-duplicates the
-replayed prefix, and exposes `joinRun(runId)` to attach to an in-flight or
-finished run from the start (read-only GET with `offset=-1`). Untagged streams
-behave exactly as before. A durable run that ends with no terminal event and no
-forward progress now throws `DurableStreamIncompleteError` instead of hanging.
-
-Reconnection and durability are bounded so failures surface rather than hang or
-loop:
-
-- `memoryStream` evicts completed logs after a grace window (unbounded growth
-  is gone); resuming an expired/unknown run throws, and a from-start join to a
-  run that never produces fails after `MemoryStreamOptions.firstChunkDeadlineMs`.
-- all four HTTP adapters accept `reconnect: { maxAttempts, delayMs }` — a
-  throttle plus a ceiling on CONSECUTIVE no-progress reconnects (default 5;
-  forward progress resets it) that fails with the new `StreamReconnectLimitError`
-  instead of reconnecting endlessly, without penalizing a healthy long-lived run.
-- `durableStream` accepts `reconnect: { maxReadFailures, delayMs }` to bound its
-  read-retry loop, and `server` is now optional when `fetch` is provided (e.g. a
-  Cloudflare service binding).
-- `toServerSentEventsResponse` accepts `debug` to record durability terminal /
-  close failures server-side, where a replaying joiner cannot observe them.

+# @tanstack/ai-durable-stream
+
+## 0.1.0
+
+### Minor Changes
+
+- [#955](https://github.com/TanStack/ai/pull/955) [`7c7aa09`](https://github.com/TanStack/ai/commit/7c7aa09a7402b45e6285ebc78a606131aec3e288) - Resumable streams: reconnect to an in-flight SSE **or NDJSON** response without
+  re-running the provider.
+
+  `toServerSentEventsResponse` and `toHttpResponse` both accept a
+  `durability: { adapter, batch }` option. The adapter (`StreamDurability`)
+  records every chunk to an ordered log before delivery and tags each event with
+  an opaque, adapter-owned offset — an SSE `id:` line, or the `id` of an NDJSON
+  `{ id, chunk }` envelope (NDJSON has no native event-id). A reconnect
+  (`Last-Event-ID`) or an explicit `?offset` read replays strictly after that
+  offset from the log — the lazy provider stream is never iterated on resume.
+  Producers terminalize the log on cancellation and failure (`RUN_ERROR` append
+  - `close()`) and on completion when the source stream emits its own terminal
+    event (`chat()` always does), so readers are never parked on a dead run.
+
+  Two adapters ship: `memoryStream(request)` in `@tanstack/ai` (process-local,
+  for development and tests) and the new `@tanstack/ai-durable-stream` package,
+  a Durable Streams protocol adapter for production backends.
+
+  For the `GET` handler that a reload or a second tab reconnects to,
+  `resumeServerSentEventsResponse({ adapter })` and `resumeHttpResponse({ adapter })`
+  replay a run straight from the durability log. They need no producer stream and
+  return a 400 when the request carries no resume offset.
+
+  On the client, all four HTTP adapters are now resumable — `fetchServerSentEvents`,
+  `fetchHttpStream`, `xhrServerSentEvents`, and `xhrHttpStream`. Each tracks the
+  per-event offset, auto-reconnects with `Last-Event-ID`, de-duplicates the
+  replayed prefix, and exposes `joinRun(runId)` to attach to an in-flight or
+  finished run from the start (read-only GET with `offset=-1`). Untagged streams
+  behave exactly as before. A durable run that ends with no terminal event and no
+  forward progress now throws `DurableStreamIncompleteError` instead of hanging.
+
+  Reconnection and durability are bounded so failures surface rather than hang or
+  loop:
+  - `memoryStream` evicts completed logs after a grace window (unbounded growth
+    is gone); resuming an expired/unknown run throws, and a from-start join to a
+    run that never produces fails after `MemoryStreamOptions.firstChunkDeadlineMs`.
+  - all four HTTP adapters accept `reconnect: { maxAttempts, delayMs }` — a
+    throttle plus a ceiling on CONSECUTIVE no-progress reconnects (default 5;
+    forward progress resets it) that fails with the new `StreamReconnectLimitError`
+    instead of reconnecting endlessly, without penalizing a healthy long-lived run.
+  - `durableStream` accepts `reconnect: { maxReadFailures, delayMs }` to bound its
+    read-retry loop, and `server` is now optional when `fetch` is provided (e.g. a
+    Cloudflare service binding).
+  - `toServerSentEventsResponse` accepts `debug` to record durability terminal /
+    close failures server-side, where a replaying joiner cannot observe them.

 # @tanstack/ai
 
+## 0.43.0
+
+### Minor Changes
+
+- [#955](https://github.com/TanStack/ai/pull/955) [`7c7aa09`](https://github.com/TanStack/ai/commit/7c7aa09a7402b45e6285ebc78a606131aec3e288) - Resumable streams: reconnect to an in-flight SSE **or NDJSON** response without
+  re-running the provider.
+
+  `toServerSentEventsResponse` and `toHttpResponse` both accept a
+  `durability: { adapter, batch }` option. The adapter (`StreamDurability`)
+  records every chunk to an ordered log before delivery and tags each event with
+  an opaque, adapter-owned offset — an SSE `id:` line, or the `id` of an NDJSON
+  `{ id, chunk }` envelope (NDJSON has no native event-id). A reconnect
+  (`Last-Event-ID`) or an explicit `?offset` read replays strictly after that
+  offset from the log — the lazy provider stream is never iterated on resume.
+  Producers terminalize the log on cancellation and failure (`RUN_ERROR` append
+  - `close()`) and on completion when the source stream emits its own terminal
+    event (`chat()` always does), so readers are never parked on a dead run.
+
+  Two adapters ship: `memoryStream(request)` in `@tanstack/ai` (process-local,
+  for development and tests) and the new `@tanstack/ai-durable-stream` package,
+  a Durable Streams protocol adapter for production backends.
+
+  For the `GET` handler that a reload or a second tab reconnects to,
+  `resumeServerSentEventsResponse({ adapter })` and `resumeHttpResponse({ adapter })`
+  replay a run straight from the durability log. They need no producer stream and
+  return a 400 when the request carries no resume offset.
+
+  On the client, all four HTTP adapters are now resumable — `fetchServerSentEvents`,
+  `fetchHttpStream`, `xhrServerSentEvents`, and `xhrHttpStream`. Each tracks the
+  per-event offset, auto-reconnects with `Last-Event-ID`, de-duplicates the
+  replayed prefix, and exposes `joinRun(runId)` to attach to an in-flight or
+  finished run from the start (read-only GET with `offset=-1`). Untagged streams
+  behave exactly as before. A durable run that ends with no terminal event and no
+  forward progress now throws `DurableStreamIncompleteError` instead of hanging.
+
+  Reconnection and durability are bounded so failures surface rather than hang or
+  loop:
+  - `memoryStream` evicts completed logs after a grace window (unbounded growth
+    is gone); resuming an expired/unknown run throws, and a from-start join to a
+    run that never produces fails after `MemoryStreamOptions.firstChunkDeadlineMs`.
+  - all four HTTP adapters accept `reconnect: { maxAttempts, delayMs }` — a
+    throttle plus a ceiling on CONSECUTIVE no-progress reconnects (default 5;
+    forward progress resets it) that fails with the new `StreamReconnectLimitError`
+    instead of reconnecting endlessly, without penalizing a healthy long-lived run.
+  - `durableStream` accepts `reconnect: { maxReadFailures, delayMs }` to bound its
+    read-retry loop, and `server` is now optional when `fetch` is provided (e.g. a
+    Cloudflare service binding).
+  - `toServerSentEventsResponse` accepts `debug` to record durability terminal /
+    close failures server-side, where a replaying joiner cannot observe them.
+
