## What's Changed

- 2026/04/18 3.1.0 Released

  This release focuses on **licensing openness, parsing accuracy, and full-format native support**. The main updates include:

  - License upgrade
    - MinerU has officially moved from `AGPLv3` to the [MinerU Open Source License](https://github.com/opendatalab/MinerU/blob/master/LICENSE.md), a custom license based on `Apache 2.0`.
    - This change significantly reduces adoption friction for both community users and commercial deployments, making MinerU easier to integrate into real-world workflows.
  - VLM main model upgrade
    - The primary VLM model has been upgraded to `MinerU2.5-Pro-2604-1.2B`, bringing overall parsing accuracy to a state-of-the-art level.
    - The new model now supports image and chart parsing, truncated paragraph merging, cross-page table merging, and image recognition inside tables, further strengthening performance on complex document layouts.
  - Full-format native parsing support
    - Native parsing support has now been extended to `PPTX` and `XLSX`.
    - MinerU now fully supports parsing across images, `PDF`, `DOCX`, `PPTX`, and `XLSX`, providing a more complete multi-format document understanding workflow.
