v0.4.0

What's Changed

New Features

Waveforms

• Added IMRPhenomXP, IMRPhenomHM and IMRPhenomXHM

Likelihood

• Added MultibandedTransientLikelihoodFD for frequency-domain multibanded analysis

Sampler module

• Full sampler module overhaul: BlackJAXNSSSampler, BlackJAXSMCSampler, and FlowMCSampler now expose a unified interface including sampling_time and diagnostics fields
• Added log_Z_error and ESS history tracking to BlackJAXSMCSampler diagnostics
• Added JAX persistent compilation cache support via configure_jax_cache
• Added elapsed-time tracking across all sampler runs

Checkpointing

• Implemented checkpoint/resume support for BlackJAXSMCSampler, BlackJAXNSSSampler, and FlowMCSampler
• Samplers now use checkpoint_dir (a directory) instead of a single checkpoint_path; the checkpoint file is written atomically and validated on resume against the initial position shape
• Added configurable checkpoint_interval; JAX cache is cleaned up on checkpoint write
• CLI config now exposes checkpointing options

Transforms

• Added GaussianTransform

Data I/O

• Data.to_file now supports multiple output formats (HDF5, npz, etc.)
• Enhanced file loading to support strain and PSD data in multiple formats

CLI (jim-run)

• Added comprehensive CLI documentation
• Added multibanded likelihood support to CLI
• Added IMRPhenomXHM to CLI waveform options
• Improved template config error handling

Breaking Changes

• is_zero_noise parameter renamed to zero_noise in TransientLikelihoodFD
• ifos renamed to detectors throughout configuration files and documentation
• Marginalized likelihood subclasses removed; use {*}_marginalization=True instead
• evaluate methods across likelihood classes no longer accept a data parameter

Bug Fixes

• Fixed optimal_snr and match_filtered_snr fields to be Optional in GroundBased2G
• Fixed nperseg to be integer in PSD calculations
• Fixed JAX jit evaluation in TransientLikelihoodFD tests
• Fixed log propagation and adjusted log levels (Tukey window message demoted to DEBUG)
• Added parameter constraint assertions in UniformPrior, GaussianPrior, and RayleighPrior

Dependency Updates

• Updated flowMC and ripple version requirements

Documentation

• Restructured documentation layout and API reference generation
• Added Mermaid.js flowcharts to quickstart and transforms guides
• Added checkpointing/resuming section in samplers.md
• Added CLI usage guide and example README files
• Updated GW170817 and GW150914 example configurations
