# Changelog
> SDK, Integrations & API improvements, features and releases
* **Valyu CLI upgrade:** The [Valyu CLI](/integrations/valyu-cli) now includes access to the most powerful Deep Research features: deliverables, human-in-the-loop, code execution, and screenshots.
* **Source biases:** New `sourceBiases` parameter in the [Search & DeepResearch API](/api-reference/endpoint/search) lets you fine-tune how search results are prioritized across different data sources, giving you more control over result ranking.
* **Deep Research screenshots:** Deep Research can now capture website screenshots and include them directly in generated reports for richer visual context.
* **Deep Research code execution:** The Deep Research API now supports code execution, enabling reports with computed results, data analysis, and programmatic outputs.
* **Deep Research HITL (human-in-the-loop):** Added human-in-the-loop support for Deep Research, allowing you to review, guide, and refine research tasks during execution.
* **Valyu CLI:** Shipped the official [Valyu CLI](/integrations/valyu-cli) for running searches, deepresearch workflows, and interacting with Valyu directly from your terminal.
* **13F/G/D SEC filing search:** You can now search across SEC 13F, 13G, and 13D filings through the [Search API](/api-reference/endpoint/search), unlocking the institutional ownership layer of public markets.
* **Async Contents API:** Added async support for the [Contents API](/api-reference/endpoint/contents), enabling non-blocking content extraction for large-scale workflows. Available in both [Python](/sdk/python-sdk) and [JavaScript](/sdk/typescript-sdk) SDKs.
* **Source biases:** New `sourceBiases` parameter in the [Search API](/api-reference/endpoint/search) lets you fine-tune how search results are prioritized across different data sources, giving you more control over result ranking.
* **Bulk batch results:** New `batch.getResults()` method lets you fetch all results from a batch in one paginated call instead of individual requests per task. Ideal for teams running hundreds of DeepResearch tasks in parallel.
* **DeepResearch email alerts:** Added `alert_email` support for custom email notifications on task completion. A new `custom_url` field lets you pass a custom report URL instead of the default platform.valyu.ai URL.
All changes above are live in the [Python](/sdk/python-sdk) and [JavaScript](/sdk/typescript-sdk) SDKs.
* **Postman-ready OpenAPI spec:** You can now easily import Valyu OpenAPI spec [directly into Postman](https://docs.valyu.ai/api-reference/openapi.json) to test all endpoints interactively.
* **Deep Research document uploads:** You can now attach and upload internal documents as sources for Deep Research reports via the Platform or API. Uploaded documents are properly cited in the final report.
