 # codex-a2a
 
+## 0.4.0
+
+### Minor Changes
+
+- 9543747: Upgrade `@openai/codex-sdk` to `^0.142.1` and surface two existing SDK capabilities:
+
+  - **Thread resume**: capture and expose the Codex `thread_id` on `thread.started`
+    (`metadata.codexAgent.threadId`); resume a context's thread after LRU eviction or via a
+    client-supplied `metadata.codexAgent.threadId` (legacy `metadata.codexThreadId` accepted).
+  - **Image input**: forward A2A `image/*` file parts to Codex as `local_image` (inline bytes →
+    temp file; local `file://` paths scoped to the working directory). Agent card now declares
+    image input modes.
+
+  Also exports a typed metadata contract so consumers don't hand-write magic keys:
+  `threadIdMetadata()`, `readThreadId()`, `CodexAgentEventKind`, `CodexAgentMetadata`,
+  `CODEX_AGENT_METADATA_KEY`, `LEGACY_THREAD_ID_KEY`, and `SUPPORTED_IMAGE_MIME_TYPES`.
+  `getWorkingDirectory` is deprecated in favor of `getThreadOptions().workingDirectory`.
+
 ## 0.3.1
