Release v5.0.x

2026-01-27

Version description of the v5.0.7 release of SlideRule Earth.

Breaking Changes¶

• v5.0.7 - The atl24-s3 asset has been renamed to icesat2-atl24 to reflect that it is now the default asset for ATL24. This will also make the transition from local S3 storage to Earthdata Cloud seamless, as the name will not need to change when that happens.

• v5.0.3 - The use of the SlideRule Provisioning System has been deprecated. All accounts in the system must be replaced by GitHub accounts. Authentication for private clusters is now handled by the SlideRule Authenticator at https://login.slideruleearth.io.

  • The Python client now supports only two authentication flows: (1) the use of a PAT key from GitHub, and (2) an interactive device-flow login to GitHub

  • Support for .netrc files has been removed

  • The environment variable PS_GITHUB_TOKEN has been renamed to SLIDERULE_GITHUB_TOKEN to remove the “Provisioning System” prefix identifier.

  • The ps_username and ps_password parameters in sliderule.authenticate have been removed.

  • The update_available_servers function can no longer be used to change the number of nodes in a running cluster; it can only be used to initialize the number of nodes in a cluster that is to be deployed and then status the number of nodes that are running.

• v5.0.3 - The use of the SlideRule Manager has been deprecated. All calls to session.manager should no longer be used as that functionality will cease in future releases.

• v5.0.3 - The main Python module sliderule no longer creates a default session on import but requires either sliderule.init() or sliderule.create_session(). The creation of a default session was confusing when users called sliderule.init() which then created a second session. This caused odd behavior with logging because at that point two loggers exist. Moving forward, users are encouraged to use sliderule.create_session() which returns a session object that can then unambiguously be used to communicate with a SlideRule cluster..

• v5.0.3 - Raster sampling support has been optimized for x-series APIs at the cost of legacy p-series API performance. All users are strongly encouraged to switch to x-series APIs when performing raster sampling as the old p-series APIs will take much longer now.

• v5.0.3 - Removed the sliderule.authenticate function as authentication must now occur when a SlideRule session is created.

• v5.0.2 - Polygons used for earthdata.stac requests no longer need to be nested lists, but are supplied in the same format as all other requests:

poly = [
    {"lat": lat1, "lon": lon1},
    {"lat": lat2, "lon": lon2},
    ...
    {"lat": lat1, "lon": lon1}
]

• v5.0.2 - The raster field which was replaced by region_mask and has been deprecated is now no longer supported.

• v5.0.2 - The nsidc-s3 asset which was replaced by the icesat2 asset, is no longer supported. Using icesat2 instead of nsidc-s3 provides identical behavior.

• v5.0.2 - The bypass_dns option in the SlideRule Python Client is no longer supported as it was not reliable.

• v5.0.2 - Queries to AMS require all parameters for the query to be inside an object with the key matching the product being queried. For example, ATL13 queries can no longer provide the refid parameter at the top level of the request json, like so:

{
    "refid": 110234231
}

Instead the request json must change to be this:

{
    "atl13": {
        "refid": 110234231
    }
}

New Functionality¶

• v5.0.7 - #574 - Copernicus DEM 30m raster support added.

• v5.0.7 - H5Coro has been updated to support dynamically modified H5 files (which was needed to read older ATL02 granules). This update uses the v2 BTree name index to access link messages in the fractal heap. Currently, this support is only provided in the h5p and h5 endpoints. In the future, this will also be available to the rest of the endpoints.

• v5.0.7 - Added /report/tests API to provisioner; it returns the summary of the results of the last test runner run.

• v5.0.3 - The django-based SlideRule Provisioning System running in AWS ECS has reached end-of-life and is now replaced by the pure Python-based SlideRule Provisioner running in AWS lambda.

• v5.0.3 - The authentication services provided by the SlideRule Provisioning System have been replaced by the SlideRule Authenticator which in turn uses GitHub athentication services for account management.

• v5.0.3 - The flask-based SlideRule Manager has been removed. Telemetry and alert logging is now handled by the AWS firehose-based SlideRule Recorder. Rate limiting and endpoint metrics are now handled the SlideRule Intelligent Load Balancer.

• v5.0.3 - #552 - Ancillary field requests now support multidimensional data.

• v5.0.3 - #553 - Added x-series APIs for ATL06 (atl06x) and ATL08 (atl08x)

• v5.0.3 - #562 - Serial-mode raster sampling has been removed.

• v5.0.3 - #564 - Added x-series APIs for GEDI04A (gedi04ax), GEDI02A (gedi02ax), and GEDI01B (gedi01bx)

• v5.0.2 - ATL24 uses release 002 by default, which uses the internal Asset Metadata Service (AMS).

• v5.0.2 - #549 - h5p now supports slices.

• v5.0.2 - earthdata.py is no longer a standalone implementation of an interface to CMR and TNM, but instead makes a request to the SlideRule cluster to execute the server-side implementations in earth_data_query.lua. This consolidates the interface to these services in one place, and also provides a consistent interface between the web and Python clients.

• v5.0.2 - Added the 3dep1m asset which accesses the same USGS 3DEP data product but uses the internal AMS service for STAC queries. This is an attempt to alleviate issues with inconsistent availability and functionality in The National Map (TNM) service which made using 3DEP difficult.
