🚀 Release Summary

This release introduces new cosmological observables, internal transformations, and improved interoperability with external libraries. It also includes performance improvements, extended modeling support, bug fixes, and documentation updates, contributing to a more modular and robust framework.

✨ What's New

✏️ New Transformations & Observables — Added first implementation of Hankel transformations for spectroscopic two-point correlation functions (2PCF) and enabled them in polar coordinates, BNT transformation for shear kernels, COSEBIs for photometric surveys (and its corresponding auxiliary functions), and added photometric RSD window support, expanding the range of supported cosmological analyses.

⭐ Extended Cosmological Modeling for non-linear scales — Introduced linear emulator modules (ΛCDM, wCDM, waCDM), BACCOemu and EuclidEmulator2 integration, and improved handling of σ₈ outputs and growth factor calculations. Also, extended support for _cb quantities.

🔗 cosmolib Integration — Added cosmolib dependency and standardized outputs (e.g., photometric and spectro dataclasses for all observables), improving interoperability and consistency across pipelines. Now, cloelib is fully compatible with euclidlib format.

⚡ Performance & Numerical Improvements — Implemented vectorized and JAX-compatible Akima interpolation, improved array handling (np.arange fix), and optimized numerical routines across modules.

🛠️ Developer Experience & CI/CD — Updated CI pipelines, improved templates (issues & PRs), refined project structure documentation, and enhanced release preparation workflows.

📚 Documentation Overhaul — Major improvements to README, modular code structure documentation, contributor visibility, and rendering fixes (e.g., Mermaid diagrams, navigation bugs). Also, full cloelib docs are now available.

🧹 Bug Fixes & Cleanup

• Fixed duplicated functions in spectroscopic modules (gh-342).
• Resolved COSEBIs key and mode handling issues (gh-405, gh-415).
• Fixed PBJ interface inconsistencies (gh-399).
• Corrected growth factor redshift usage in IA window (gh-414).
• Fixed numerical integration naming (trapz → trapezoid) (gh-450).
• Addressed formatting and rendering issues in documentation and navigation.
• General cleanup of deprecated components (e.g., removal of _version.py).

⚠️ Breaking Changes

Introduction of cosmolib dependency and refactoring of outputs (e.g., COSEBIs and spectro observables) may require minor adaptations in downstream pipelines. This implies that some formats have been altered. Please, re-install and check new playground notebooks.
