Releases

Welcome to the Releases page for Dendra, where we document major updates to the platform. Release 3 is in active development and available at https://app.dendra.science/. Release 2 remains the stable production platform (in production since 2019) at https://ui.dendra.science/.

Release 3 Changelog#

Release 3 MVP (end of October 2026)#

Planned Features:

  • Code Library for datastream transformations and calculations.
  • Multi-org query interface: Prototype map and search for sites and datastreams.

Release 3 MVP (2026-09-24)#

What’s New:

  • API: Initial data querying API for accessing datastreams and their data.
  • Flexible Units: Just about any unit can now be specified when defining datastreams. Units are used for automatic conversion, and are based on the same units as Python Pint.
  • Data connector for Release 2 to utilize Release 3 data querying API. Allows for migration of hand-coded unit conversions to automatic unit conversion.

Release 3 MVP (2026-08-23)#

What’s New:

  • Web App: Manage user and organization access keys. Pipeline tree on Monitor Integrations. Additional links to setup docs.
  • Integrations: Self-serve station webhooks for posting data in standardized formats. Improved LI-COR backfill handling.
  • Dendra Agent: Integration how-tos (including webhooks) and site/station location.
  • MCP Server: Site and station location on entity lookup, plus integration docs for agent workflows.

Release 3 MVP (2026-08-16)#

What’s New:

  • Web App: Clearer Monitor Integrations page, stronger checks when creating datastreams and integrations, station readiness that includes the site, and recommended vocabulary for organizations.
  • Integrations: Self-serve LI-COR Cloud (HOBOlink) setup with your Cloud API key, including historical backfill while recent data keeps coming in.
  • Dendra Agent: More reliable answers, with better use of docs and organization metadata.
  • MCP Server: Docs search and entity count tools for agent workflows.

Release 3 MVP (2026-07-25)#

What’s New:

  • Dendra Agent for management questions and setup.
  • Campbell Scientific LDMP integration improvements.
  • New load worker for data ingestion (no archiving).
  • Common time-series store for multiple organizations.
  • New foundation for rule-based alerts.
  • Email notifications for joining and approving organization membership requests.

Release 3 Alpha (2026-05-28)#

What’s New:

  • Campbell Scientific LDMP integration ported from Release 2 with improved control, visibility and error handling.
  • New data integration orchestration system with API access to all features, support for live/test mode.
  • New integration monitoring page to troubleshoot data integrations and their pipelines.
  • Job scheduler improvements. Job provider/hydration implemented for integrations.
  • Reverse sync to Dendra Release 2 for individual stations.
  • General web app improvements and page gating based on permissions.

About Release 3#

Status: New (in development)

Availability: Live at https://app.dendra.science/

Platform Overview#

  • Backward compatibility with Release 2 to ease migration.
  • Existing Release 2 capabilities preserved and extended.
  • Redesigned and focused management interface, separating management from data exploration.
  • Streamlined station setup and datastream configuration workflows.
  • Self-service integration setup so organizations can connect telemetry on their own.
  • Data file import from CSV, TOA5, and additional formats.
  • Equation (code) library for calculated datastreams and data ingestion transformations.
  • Improved annotation, station status and monitoring capabilities.
  • Redesigned cross-organization data exploration interface.
  • Protocol Buffer–based API (JSON over HTTP) with client libraries: https://buf.build/dendrascience/repositories
  • API key provisioning for programmatic access.
  • AI-assisted semantic search for data exploration and an MCP server for agent workflows.
  • New job scheduler for background ingestion, vendor integrations, orchestration and notifications, aligned with the new API.
  • Upgraded vendor integrations: same coverage as Release 2, simpler to operate and extend.
  • Improved support for multiple database technologies and sharding across servers for scale and availability.
  • System tuned for performance, flexibility, and efficient operation.

See Features by Release for more details.

About Release 2#

Status: Stable (in production since 2019)

Availability: Live at https://ui.dendra.science/

Platform Overview#

  • Researcher-designed data exploration (query) interface.
