PySDM v2.26

• breakup function renaming withing backend code (#1126) - @abulenok
• phasing out "q" var naming in favour of "water_vapour_mixing_ratio", etc (#1131)
• updates to the Grabowski & Pawlowska 2023 example: condensation tolerance, ripening rate (#1129) - @AgnieszkaMakulska
• cleaning up code that triggered redefined-outer-name pylint warning in pytest fixtures and notebook-embedded function definitions (#1133)
• ensuring all classes are accessible after importing only the main PySDM package (#1135)

PySDM v2.25

• new example notebooks and smoke tests covering complete set of figures from Grabowski & Pawlowska 2023
• new product base class: _ActivationFilteredProduct
• new products based on the above: ActivatedParticleConcentration, ActivatedParticleSpecificConcentration, ActivatedMeanRadius
• new size-spectral products: MeanVolumeRadius, AreaStandardDeviation, RadiusStandardDeviation, VolumeStandardDeviation
• new attribute: EquilibriumSupersaturation
• cleanups in Yang_et_al_2018 example (incl. using the above new products instead of manually computing the activation-filtered quantities)

kudos @AgnieszkaMakulska!

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)
