openai/codex removed its deprecated thread/rollback API and wired disabled-plugin selection plus access-program metadata through the app-server, while openai-node and openai-python both picked up Steady multipart and streaming fixes.

openai/codex removed the deprecated `thread/rollback` API along with its request and response types, generated bindings, and the core `Op::ThreadRollback` operation [1]. Requests to it now take the generic unknown-method rejection path, and the documentation points at `thread/revert` as the alternative for paginated threads. Historical `ThreadRolledBack` markers and legacy error deserialization are kept so existing rollouts still replay and migrate. If you call `thread/rollback`, this is a breaking change: it used to resolve and now fails as an unknown method.

Plugin selection is now part of the app-server surface. `thread/settings/update` and `turn/start` accept `disabledPluginIds`, where a supplied list replaces the saved selection, omission or `null` preserves it, and `[]` clears it [2]. The selection comes back in thread start, resume, and fork responses and in `thread/settings/updated` notifications, with generated schemas and client types updated, and disabled plugin IDs are restored from the history retained at the requested fork boundary.

Model discovery carries optional `available_access_programs` metadata through model information, presets, caches, and the TUI, exposed as `availableAccessPrograms` in app-server `model/list` responses [3]. The distinction between missing metadata and an empty `cyber` list is preserved, and unknown cyber program names are ignored when reading the catalog so new server programs do not break older clients.

Separately, openai-node and openai-python both bumped Steady to the latest `main` revision to pick up the multipart and streaming fixes [4][5].
