## Change to Job Information Retention Period (Effective December 2025)

To ensure the stability and performance of our service, we are introducing a new limitation on the data retention period for job information.

- Currently, there is no expiration date for accessible job information.
- But, we will begin gradually deleting older data. Eventually, only job information created within the last 1 year will be accessible.
- This limitation will affect all methods of accessing job information, including TD Console, REST API, and all other ways.


## API Documentation Version Update with AI-Powered Search

- Our API documentation ([Treasure Data API Developer Portal](https://api-docs.treasuredata.com/)) has been upgraded to a new version, introducing a "Search with AI" feature that enables users to explore documentation through conversational, natural language queries.
- This enhancement benefits all developers and technical users by allowing them to ask questions and receive intelligent, context-aware answers directly within the documentation, significantly improving the learning experience and reducing time to integration.
- The upgrade will be available on November 3, 2025, with no URL changes or user action required.


## Amazon Ads Connector Update: EU/UK Consent Compliance

- The Amazon Ads connector now requires customers exporting audiences or syncing cookies for UK/EEA users to include country_code, consent_type, and a valid consent string (IAB TCF or Amazon Consent Signal) to meet new EU/UK consent regulations effective November 15, 2025.
- This update is essential for customers targeting users in the UK/EEA, as data without the required consent information will be rejected by Amazon Ads; no changes are needed for audiences outside these regions.
