PySDM v2.24

• switching from "n" to "multiplicity" for attribute key (#1123)
• improving reporting of filenames in pytest example test suites (#1121)

PySDM v2.23

• linear (instead of constant) density/pressure profile for condensation in parcel environment (kudos @mikhailmints)
• updates in immersion freezing example to match arXiv-uploaded figures
• using the CI env var to trigger FakeThrust (thus making it easier to locally reproduce CI behaviour)
• renumbered figured in de Jong et al. breakup example to match final paper
• new tests (codecov now reports 80%!), code cleanups

PySDM v2.22

• RelaxedVelocity dynamic (allowing for relaxation to terminal speeds) and relative fall velocity attribute refactor
• mermaid diagrams in README depicting PySDM submodule organisation and what's being passed where in the hello-world example

thanks to @bradybhalla and @edejong-caltech!

PySDM v2.21

• PySDM-examples repo contents moved into PySDM repo (retaining separate PyPI packages)
• introducing test suites to shorten time-to-completion of CI runs
• switching from BDF to LSODA SciPy solver for condensation tests
• speeding up super-droplet count product
• using devops_tests in CI to share common test code across open-atmos projects
• more test cases added for test_n_breakups
• clarified literature references (incl. class dependency structure) in latent heat, diffusion kinetics and diffusion thermics formulae

thanks @claresinger, @abulenok and @AgnieszkaMakulska for contributions, reviews and issue reports.

PySDM v2.20

• updated multi-step breakup algorithm (kudos @abulenok & @edejong-caltech)

PySDM v2.19

• Fixes to Straub fragmentation function and sampling methods
• addition of (draft of) LowList1982 fragmentation function and coalescence efficiency

kudos @edejong-caltech, thanks @abulenok for reviews and help!

PySDM v2.18

• breakup internals fixes, refactors and cleanups - kudos @edejong-caltech & @abulenok
• smoke tests comparing against analytic solution of SCE with breakup terms (Srivastava 1982) - kudos @abulenok
• added ConstantSize breakup fragmentation function

PySDM v2.17

• making spatial, spectral and spectro-glacial sampling reproducible (obeying seed settings in Formulae)
• replace uses of debug-intended (and slow) __setitem__ (e.g., within frag functions) with newly introduced fill() Storage method
• remove unused fields (vmax and x_plus_y) from AlwaysN frag fun
• enabling --durations reports in pytest logs
• CI workflows cleanups (grouping readme-snippets jobs, renaming)

PySDM v2.16

• enabling breakup smoke tests on GPU - kudos @abulenok!
• reflecting github org change in readme, docstrings, etc
• JOSS v2 paper updates (@claresinger & @edejong-caltech)
• minor code compatibility fixes for GPU
• minor collision code refactor: move cut_working_length call into adaptivity loop (thanks @piotrbartman)
• added zenodo-json-checking CI workflow
• added asserts for test_trickier_formula_vectorised (thanks @douglowe for reporting it)
• instantaneous ice melting support (as in Shima et al. 2020) as an option for Freezing dynamic (disabled by default)

PySDM v2.15

• major updates in collision methods (mostly GPU support for breakup, but also CPU refactors and cleanups & improved test coverage) - kudos @abulenok!
• numerous updates to FakeThrustRTC to support the above - kudos @abulenok
• cleanups and docstrings in Formulae-related code - kudos @abulenok
• clarification (significant) in displacement methods arg names (omega -> position_in_cell) - kudos @piotrbartman
• fragmentation functions moved (partially) into physics submodule
• introducing ConcentrationProduct base class supporting standard-temperature-and-pressure (STP) normalisation
• Multiplicities::MAX_VALUE and unit test (+usage in breakup dynamics)
• .zenodo.json file added to streamline Zenodo metadata provision
