Performance, Reliability, & API Updates

Machine Learning Updates

Increased the maximum file size limit for anonymizer processing, resolving issues where large text file uploads were rejected.
Added line-level deduplication in the anonymization pipeline for highly repetitive text, reducing processing time for large files.

Fixed Issues

Data Protection

Fixed some data types not triggering Data Protection guardrail detection, including tokenized card numbers and SAQ form identifiers.
Fixed false positive detections where common English words starting with 'cav' (e.g., 'caveat', 'cave') were incorrectly flagged as Authentication Credentials.
Fixed Data Protection guardrail not triggering for large text file uploads (50 MB and above).
Fixed an issue where changing a Data Protection policy action from Block to Warn prevented some prompt submissions in Claude desktop and web.
Fixed streaming responses not being buffered when credit card numbers were included in Japanese-language prompts. Previously, some responses containing sensitive data in Japanese were streamed instead of buffered as expected.

Alerts: Fixed duplicate alerts generated from a single prompt.

Access Control: Fixed group-based role access controls failing.

365 Copilot Corporate: Fixed streaming not working when a Data Protection guardrail was enabled.
