- fragmentation functions for GPU backend (abulenok)
- implement `flag_zero_multiplicity` on GPU backend within a `Commons` struct (abulenok)
- new pair and storage methods for GPU: `min_pair`, `multiply_pair` and `divide_if_not_zero` (abulenok)
- made ABIFM immersion freezing logic employ supersaturation constraint (to be consistent with analogous condition in INAS logic)
- breakup algorithm: fix an issue with zero multiplicities (introduced `max(round(nj), 1)`) (edejong-caltech)
- shift from per-gridbox to per-kg units in rate product (edejong-caltech)
- smoke test for Bieli et al. example (edejong-caltech)
- make CPU `find_pairs` correctly handle the length argument (abulenok)
- added Python 3.10 to CI runs
- added smoke tests with 0D simulations covering breakup (upcoming deJong et al. paper)

- smoke test comparing dry/wet equilibrium calculation against PyPartMC (thanks zdaq12)
- avoiding divide-by-zero warnings in `EffectiveRadius` product
- fix physical unit in size-spectrum products (thanks sajjadazimi)
- better array-valued argument handling in `Formulae` methods using `numba.vectorize` (thanks claresinger)
- new method: `Builder::replace_dynamic()` (edejong-caltech)
- handling NVRTC_PATH env var to point ThrustRTC to non-standard location of nVidia libs (abulenok)
- new backend methods: `min_pair`, `divide_if_not_zero` (edejong-caltech)
- GPU support for freezing
- 3D displacement incl. GPU support (abulenok)
- Straub fragmentation function (edejong-caltech)
- breakup algorithm improvements incl. reworked limiter logic, `fragment_size` instead of `min_volume`, fragmentation function updates (edejong-caltech)
- backends: fixed `__init__` calls in multiple-inheritance contexts
- FakeThrust fixes to better match ThrustRTC API (abulenok)
- make formulae available at attribute mapper scope so `request_attribute` can be called without constraints
- storage, attribute, mesh common code: improved test coverage, cleanups, docstrings (abulenok!)
- multi-stage Github Actions workflow (pylint, no-numba unit tests, etc first, only then run all the tests
- updates to make the code clean with newer versions of pylint
- new tests for displacement, freezing, breakup, mesh, builder, formulae and storage logic

- major updates in breakup algorithmics (no more while loop, fixes) and test coverage - thanks edejong-caltech!
- new surface-tension model tests + code fixes and cleanups - thanks claresinger
- new product: averaged terminal velocity - thanks sajjadazimi
- new freezing-related products: `IceNucleiConcentration`, `FrozenParticleConcentration`
- new attribute: `WetToCriticalVolumeRatio`
- added Fierce diagrams as a test for differences between full and linearised kappa-Koehler formulae - thanks nriemer for hint!

- fixing version indicators for dependencies in pypi.org-published files (regression introduced when automating package uploads)
- option to toggle overflow warning in the breakup dynamic (thanks edejong-caltech)
- replacing r_crit<r_dry errors in wet-size equilibrium calculations with r_wet=r_dry setting (workaround for big-f_org/small-sized aerosols, thanks claresinger)
- immersion freezing cleaups
- cleaning up imports from deprecated packages in SciPy (just subpackage naming changes)

- fragmentation limiters (by edejong-caltech)
- 1D VTK and nceCDF exporters (by sajjadazimi)
- PyPI release automation through GitHub Actions
- introducing test-time-dependency on PyPartMC

- option to skip thd update in condensation dynamic added (for KiD example, kudos sajjadazimi!)
- JOSS PySDM v2 paper updates (kudos edejong-caltech & claresinger)
