Anthropic Python SDK v0.97.0 Adds CMA Memory Feature in Public Beta
Anthropic has released version 0.97.0 of its Python SDK, introducing CMA Memory as a public beta feature. The update includes bug fixes for API spec errors, restored missing features, and performance improvements for multipart file requests.
Anthropic Python SDK v0.97.0 Adds CMA Memory Feature in Public Beta
Anthropic released version 0.97.0 of its Python SDK on April 23, 2026, introducing CMA Memory as a public beta feature alongside bug fixes and performance improvements.
Key Changes
The primary addition in this release is CMA Memory, now available in public beta. The SDK update does not provide technical details about CMA Memory's functionality or implementation in the changelog.
The release addresses multiple API specification issues. Bug fixes include corrections to errors in the API spec and restoration of previously missing features that had been inadvertently removed.
Performance and Technical Updates
The SDK includes a performance optimization for handling multipart requests. According to the changelog, the client now optimizes file structure copying in multipart requests, though specific performance metrics are not disclosed.
Additional technical changes include:
- Addition of a missing import statement
- Enhanced bootstrap script robustness
- Test dependency update to steady v0.22.1
What This Means
This SDK update appears to be a significant feature release for Anthropic developers, with CMA Memory being the headline addition. However, the changelog provides minimal context about what CMA Memory does or how it functions, leaving developers to reference separate documentation. The bug fixes addressing API spec errors and missing features suggest the previous version (0.96.0) may have had stability issues that are now resolved. The performance optimization for multipart requests could benefit developers working with file uploads or structured data submissions, though the actual performance impact remains unquantified.
