Newest change January 8, 2026 ## 1.133.0 1 breaking change, first published January 8, 2026. - **Behavior changed** Saving a model to a Vertex Experiment now requires a uri or staging bucket configuration. Code that omits both will now fail.

Code that reads or sets it must be updated. [github.com](https://github.com/googleapis/python-aiplatform/releases/tag/v1.129.0) - **Renamed** `FeatureOnlineStore.bigtable_metadata` The bigtable_metadata field on FeatureOnlineStore was renamed. Code that uses the old field name must switch to the new name. [github.com](https://github.com/googleapis/python-aiplatform/releases/tag/v1.129.0) - **Renamed** `FeatureOnlineStore.enableDirectBigtableAccess` The enableDirectBigtableAccess field on FeatureOnlineStore was renamed.

[github.com](https://github.com/googleapis/python-aiplatform/releases/tag/v1.129.0) - **Default changed** `create_agent_card` The default input and output modes used by create_agent_card were changed.

[github.com](https://github.com/googleapis/python-aiplatform/commit/42167900de819d82afb7dde93238fb9926738867) ## 1.121.0 1 breaking change, first published October 15, 2025. - **Removed** `transfer_to_agent` The deprecated transfer_to_agent parameter was removed in this release, so code that passes it will no longer work and must stop using it. [github.com](https://github.com/googleapis/python-aiplatform/releases/tag/v1.121.0) ## Check your code These are the changes. To see which of them reach your code, [scan a public repository](https://since.dev/scan.md), or have your coding agent call `check_code` with your manifest or lockfile over [MCP](https://since.dev/docs.md#mcp). [The API](https://since.dev/docs.md#api) reads every change in every version, not only the newest. On Team and up, a fix pull request opens for the changes that reach a connected repository. Nothing merges or deploys. ## Put your code on continuous management. Scan a public repository now, or give your agent one line. ### See how out of date your code is. [Scan a repository](https://since.dev/scan.md). Any public GitHub repository. No sign-in. ### Tell your agent what changed since it was trained. `claude mcp add --transport http since https://api.since.dev/mcp` --- Every page on this site as Markdown: https://since.dev/sitemap.md.
