v0.26.x series (current stable)#

v0.26.0 (8th March 2024)#

Yanked release.

This is a major release. This is a summary of the most important changes:

We dropped support for Python 3.8, following the Numpy deprecation policy. If you are using our PyPI package, you will need to create a new environment based on Python 3.9 or more recent to upgrade to v0.26.0. If you are running a development setup, you will need to recreate your dev environment accordingly with the development environment setup instructions.
We provide now experimental support for Windows. Please reach out through our issue board or discussions forum if you need help.
We added the Hapke surface reflection model (see the HapkeBSDF API documentation). This model primarily aims at representing bare soil (without) vegetation).
A new post-processing pipeline architecture, based on the Hamilton library, streamlines our post-processing, improves its flexibility and maintainability. While this should not have a noticeable impact from a user’s perspective, it will allow the implementation of several features prevented by the old pipeline system. A tutorial showcases a few features of this new system.
We introduced a new scene loader based on JSON files designed to facilitate the loading of mesh-based canopy scenes. The scene loader is described in a user guide page, and a simplified interface automating the loading of the RAMI-V scenarios is provided.

Split bitmap-to-xarray converter between data array and dataset steps (PR383).
Add an Ubuntu-Based Dev Container for the Eradiate development environment (PR384).
Add support for the Hapke BSDF model (PR386).
Add experimental support for the Windows platform (PR390).
DistantFluxMeasure can now be instantiated with the factory alias distantflux (PR387).
Add a new scene loader functionality (PR392).
Add support for preconfigured RAMI-V scenarios (PR392).

Fix unit definition bug (PR393).
Fix non-portable path handling (PR390).
Fix number representation bug on Windows (PR390).
Fix a bug in MultiDeltaSpectrum that would prevent using a number of wavelengths larger than the size of the default spectral discretization (PR387).
Fix a bug in mi_render() where array-to-int casting was not done correctly (PR387).

🖥️ Allow different package specifications for Pip and Conda (PR385).
🖥️ Registered modes are now stored as Mode instances (PR387).
🖥️ BinSet and WavelengthSet now inherit from a common SpectralSet interface (PR387).
🖥️ The BinSet class’s interface is extended with properties returning bin bounds and centres (PR387).
🖥️ The BinSet.from_absorption_data() method was refactored for improved maintainability (PR387).
🖥️ Bin selection routine test code was rewritten and relocated to the test file related to the parent class (PR387).
🖥️ The MultiDeltaSpectrum code was refactored for improved maintainability (PR387).

This is a fix release.

The repr of some fields of the AtmosphereRadProfile and MultiDeltaSpectrum classes was modified for improved readability (PR395).
The extra_objects field of the EarthObservationExperiment subclasses can now be initialized with None (PR395).

When opening a molecular absorption coefficient database, bins are sorted by ascending lower bound values (PR395).
Fix a bug in post-processing pipelines where radiosity node would not appear for in situ sensors (PR395).

This is a fix release.

Required custom Mitsuba build bumped to v0.2.1 (based on Mitsuba v3.4.1). This update contains fixes for the Hapke BSDF plugin.
