openEO API 1.3.0 and openEO Processes 2.0.0 RC2 released

Written on February 3, 2026 by Matthias Mohr.

Today, we have released the new version 1.3.0 of the openEO API. At the same time, we've also released openEO Processes 2.0.0-rc.2.

These releases continue the journey towards first-class vector data cube support, while also bringing a number of quality-of-life improvements for implementers (back-ends) and consumers (clients).

Back-ends and clients are advised to check their implementations against the new specifications and update accordingly.

Below you can find details about the individual releases:

openEO API v1.3.0

openEO API 1.3.0 contains a set of improvements, clarifications and new capabilities, with a strong focus on authentication, batch job metadata and interoperability.

• API documentation (opens new window)

Please consult the changelog (opens new window) for the full list of changes and additions.

API Highlights

• New extensions:
  • Processing Parameters Extension (opens new window)
  • Remote Process Definition Extension (opens new window)
  • Workspaces Extension (opens new window)
• Authentication updates: Support for standard JSON Web Tokens (JWT) as Bearer tokens, while deprecating the openEO-specific token format.
• Batch job metadata improvements: Additional timestamps such as queued, started and unpublished, a status diagram, and extended timestamps in STAC results.
• Improved logging: Added stacktrace to log entries to simplify debugging.
• Discovery and process metadata tightened: GET / now requires the fields type and conformsTo; GET /processes adds a version property for processes; GET / also adds a new web-editor link relation type.
• Deprecations: STAC 0.9.x is deprecated.

Feedback is more than welcome. Please report issues and questions through the GitHub issue tracker (opens new window). The next version is likely v1.4.0, work has started.

openEO Processes v2.0.0-rc.2

openEO Processes 2.0.0-rc.2 is the second release candidate of the upcoming 2.0 release series. It builds on the 2.0 work that introduced the datacube data type and vector cube support, and continues to improve process definitions, consistency and implementability.

Please note that some changes are breaking changes. Make sure to review the changelog carefully before updating implementations.

• Processes documentation (opens new window)

Please consult the changelog (opens new window) for a full list of changes and additions.

Processes Highlights

• Implementation support: A new implementation guide for implementing OGC API - Processes in openEO, plus a dedicated set of unit tests.
• New processes:
  • export_collection, export_workspace
  • run_ogcapi, run_ogcapi_externally
  • stac_modify
  • text_find
• More stable processes: apply_polygon, date_between, date_shift, filter_labels and inspect are now marked as stable.
• Behaviour and consistency updates:
  • save_results returns the STAC resource (instead of boolean true).
  • all returns true for empty arrays; any returns false for empty arrays.
  • apply_polygon renamed parameter polygons to geometries.
  • clip throws an exception if min > max. #472 (opens new window)
  • date_difference allows week as a unit.
  • is_nan returns false for non-numerical data types. #486 (opens new window)
• Clarifications and fixes across the board: Improved handling of NaN, null and no-data values, added uniqueness constraints for various array-typed parameters, and numerous targeted fixes (e.g. geometry dimension type clarifications).

As this is a release candidate, feedback is more than welcome. Please report issues and questions through the GitHub issue tracker (opens new window). The next version is likely v2.0.0 (stable).
