We’re happy to announce the release of Siren Investigate 13.5.0.

Check [here](https://docs.siren.io/siren-platform-user-guide/13.5/release-notes.html) for what’s new in this release while following are the release notes:

### [New Features]

- Adds the capability of dynamically filtering the records for faster and better results. For more details, see Dynamic filters.
- Adds support for OpenSearch 2.8.x.

### [Improvements]

- Improved the highlighting of open groups in the graph browser.
- Added the ability to invert the direction of aggregated relations in the graph browser.
- Reduced the number of fields retrieved to reduce the network transfer for saved graphs.
- Added a confirmation modal to save the unsaved graphs when switching out of the dashboard.
- Significantly reduced the delay when opening or collapsing a graph browser group.
- Added the method `dataModelEntity.getFields()` that returns metadata of the fields from the entity.

### Security fixes

- Bumped PostCSS to version 8.4.31. Refer to [CVE-2023-44270](https://www.cve.org/CVERecord?id=CVE-2023-44270).

### Bug fixes

- Fixed an issue where adding nodes from a saved graph would not update the toolbar correctly.
- Fixed a bug in the rounding of the end dates of date intervals, which were incorrectly rounded down and not up to the time precision defined in the advanced setting `siren:timePrecision`.
- Fixed a bug that prevented the use of autocompletion in the script editor.
- Fixed an issue in the upgrade, backup, and restore scripts that didn’t allow you to override properties set in `investigate.yml`.

### Known issues

- For users with Searchguard authentication, Siren Federate versions _after_ 7.17.12 are currently unsupported due to issues with authentication headers. Users with Searchguard authentication are advised to remain on Elasticsearch 7.17.12 until the release of Siren Federate 7.17.15-33.1.
