Version 2.36.0 was released on 2026-05-07 and adds two features: API manual updates and “realtime 2.” The update appears focused on API behavior rather than model changes, with no additional details given beyond the changelog entries.

v2.35.1, released on 2026-05-06, fixes an API regression in the image generation size enum compared with v2.35.0. The change is a narrow bug fix, but it prevents imagegen requests from breaking or using invalid size values after the earlier enum regression.

Version 2.35.0 was released on 2026-05-06 with API changes for image 2 and manual updates, plus a documentation update to the `top_logprobs` parameter across chat and responses. It also removes the legacy Python CLI and renames its entrypoint, signaling a cleanup of older interfaces.

v0.100.0 was released on 2026-05-06 with API support for Managed Agents multiagents and outcomes, plus webhooks and vault validation, and it also adjusts webhook configuration. The update matters because it expands agent orchestration features and improves integration reliability for API users.

v0.99.0, released on 2026-05-05, adds a client feature that allows targeting a specific workspace when performing OIDC federation token exchange. This matters because it gives finer-grained control over authentication flows in multi-workspace setups.

v0.98.1 was released on 2026-05-04 as a small maintenance update over v0.98.0, with the only listed change being a typo fix in an example (#1754). It matters mainly as a housekeeping release, showing no functional changes beyond documentation/example cleanup.

Version 2.34.0 adds new API fields like `external_key_id` for projects, `email`/`metadata` for users, support for Admin API Keys per endpoint, and env-based header configuration. It also fixes auth and type issues around Azure headers, admin key handling, and Response timestamps, while improving multipart file-copy performance and updating file rate-limit/vector store docs.

v0.98.0, released 2026-05-04, improves the Managed Agents APIs and adds client auth features including Workload Identity Federation, interactive OAuth, auth profiles, and environment-based header configuration. It also fixes streaming stop details propagation, multipart file-array field naming, and missing us/eu multi-region base_url branches in the Vertex async client.

v2.33.0 was released on 2026-04-28 with an API update, plus a bug fix that corrects the `prompt_cache_retention` enum value from `in-memory` to `in_memory`. The change matters because the enum fix restores the expected API naming and avoids integration errors for clients relying on that field.

v0.97.0, released on 2026-04-23, adds a public beta for CMA Memory in the API, fixes errors in the API spec, restores missing features, and optimizes file structure copying in multipart requests. The update also includes a more robust bootstrap script and a test dependency bump to steady v0.22.1, which suggests a mix of new capability and reliability work.

v0.96.0, released on 2026-04-16, adds api support for claude-opus-4-7, token budgets, and user_profiles, and removes the release-doctor workflow from CI. The update is notable because it expands model and account management features while simplifying release automation.

Version 2.32.0, released 2026-04-15, adds richer `InputFileContent` detail, a new `OAuthErrorCode` type, and websocket client support for event handlers, enqueuing while disconnected, and reconnection. The notable fix ensures file data is sent as a single parameter, which can prevent API payload bugs, and the docs examples were improved.

v0.95.0, released on 2026-04-14, marks Sonnet 4 and Opus 4 as deprecated and changes the Bedrock mantle client to use an auth header. The deprecation signals a model lifecycle shift for Anthropic’s 4-series models, while the auth-header change is a backend integration update for Bedrock users.

v0.94.1 was released on 2026-04-13, with a single bug fix in streaming to add missing events. This matters because it addresses event loss in streamed output, which can affect downstream consumers relying on complete updates.

v0.94.0, released on 2026-04-10, adds support for a Vertex EU region and includes bug fixes plus documentation/example updates. The file-data fix ensures file data are sent as a single parameter, which can avoid request formatting issues in downstream integrations.

v0.93.0 was released on 2026-04-09, and its only listed feature is an API addition of a beta advisor tool. The change is notable mainly because it introduces a new beta tool in the API surface, with no other features called out in the changelog.

v2.31.0, released 2026-04-08, adds a `phase` field to conversation messages, support for short-lived tokens, raw data over websockets, and an indices array format for query/form serialization, while also briefly adding then removing `web_search_call.results` from `ResponseIncludable`. The update matters because it expands client and API capabilities and fixes a query-parameter merging bug that could overwrite hardcoded params, with the changelog also noting docs updates for vector store file parameters and test dependency bumps to steady v0.20.2.

Version 2.30.0 adds a `keys` field to `Click`, `DoubleClick`, `Drag`, `Move`, and `Scroll` computer actions, and updates SDK response types to match expanded item schemas while making `type` required in `ResponseInputMessageItem`. It also sanitizes endpoint path params and switches tests from prism to steady, with steady bumped through v0.19.7.

v2.29.0, released on 2026-03-17, adds 5.4 nano and mini model slugs, a `/v1/videos` endpoint for `batches.create`, a `defer_loading` field on `ToolFunction`, and `in`/`nin` operators on `ComparisonFilter`. The update also bumps the minimum `typing-extensions` version and fixes a `pydantic` alias-handling issue, which should improve API coverage and type/runtime compatibility.

v2.28.0, released on 2026-03-13, adds an API feature for custom voices. The change is notable because it exposes voice customization through the API, extending control for applications built on the platform.
