Release 0.3.0

• Add VELOVI
• Add method to infer transcription rates based on metabolic labeling data
• Fix bugs s.t. code runs with latest versions of numpy, pandas, matplotlib

v0.2.5

Release `0.2.5` (#934)

* Add .editorconfig (#529)

* Add TestCleanObsNames (#530)

Add test class for `scvelo/core/_anndata.py::clean_obs_names`.

* Refactor `clean_obs_names` (#532)

* Rename input arguments from `data` to `adata`, `copy` to `inplace`,
`ID_length` to `id_length`, `base` to `alphabet`.

* Rename variables to something more meaningful and use snake as well as
lower case, consistently.

* Make use of Pandas functionality.

* Use regex expression.

* Move unit tests to `tests/` (#535)

* Move `scvelo/core/tests` to `tests/core`

Moves unit tests `scvelo/core/tests` to `tests/core`. This will, for
example, prevent installation files becoming large when including data
or ground truth figures.

* Add `tests/__init__.py`

Makes `tests/` a package. This is needed to e.g. import from `tests/core`
later on.

* Update pytest.ini

Remove `scvelo` from testpaths.

* Fix and refactor `filter_genes` (#537)

* Add `multiply`

Adds function to calculate the element-wise product of two arrays or an
array and a sparse matrix.

* Fix and refactor `filter_genes`

The original implementation fails when `adata.layers['unspliced']` is
sparse but `adata.layers['spliced']` dense. The element-wise
multiplication is now performend using `multiply`.

* Add column generation for adata.obs/.var (#544)

* Fix and update docstrings

Update docstrings to follow codebase style.

* Add option to add columns to adata.obs

* Adds `obs_col_names`, `min_obs_cols`, `max_obs_cols` to composite
strategy `get_adata`. Using `obs_col_names`, the column names can be set
manually, the other arguments allow setting the minimum and maximum
number of columns generated.

* Updates unit tests to encounter for and test changes.

* Add option to add columns to adata.var

* Adds `var_col_names`, `min_var_cols`, `max_var_cols` to composite
strategy `get_adata`. Using `var_col_names`, the column names can be set
manually, the other arguments allow setting the minimum and maximum
number of columns generated.

* Updates unit tests to encounter for and test changes.

* Add unit tests for `cleanup` (#548)

* Add method `_subset_columns` to `TestBase`

Adds method to sample from column names in `adata.obs` and `adata.var`.

* Add `TestCleanup`

Adds test class to unit test `scvelo/core/_anndata.py::cleanup`.

* Fix TestCleanup::test_cleanup_some (#550)

* Refactor `cleanup` (#552)

* Rename argument `data` to `adata`

* Rename argument `copy` to `inplace`

* Update type hint in `cleanup`

* Rename variables

Rename variables to use more informative names.

* Add `TestGetInitialSize` (#554)

* Add `TestGetSize` (#556)

* Refactor module import (#560)

* Delete `pl.py`, `pp.py` and `tl.py`.
* Update `__init__.py` to no longer rely on `pl.py`, `pp.py` and
`tl.py`.

* Update `get_modality` (#567)

* Update `get_modality`

Support passing `None` for argument `modality`. In this case, `adata.X`
is returned.

* Add `TestGetModality::test_modality_equals_none`

Add unit test to check that correct modality is extracted if `None` is
passed for `modality` in `get_modality`.

* Refactor and generalize `get_size` (#569)

* Rename `layer` to `modality`

Rename argument `layer` to `modality` in `get_size`. This unifies naming
convention for the argument across the code base and prepares
generalizing `get_size` to arbitrary modalities.

* Generalize `get_size` to arbitrary modalities

This allows calculating the size per observation for any modality, from
`adata.X`, `adata.layers` or `adata.obsm`.

* Update docstrings

* Add TestObsDf (#579)

Unit tests `scvelo.core._anndata.py::obs_df`.

frame is correct.

Add unit tests to `TestMakeDense` and
`TestMakeSparse` when `modality` is passed as a string.

Generate layer names with at least two characters to exclude the case
`layer='X'`.

Converts unit test to a test class. 2D arrays and sparse matrices are
now generated as well to increase coverage to 100%.

* Add `varm` to AnnData strategy (#609)

* Add `varm` to AnnData strategy

Strategy can now also add entries to `adata.varm`. This is tested by
extending the existing unit tests.

* Set `max_obs` and `max_vars` to `5`

This is an attempt to make the unit tests not in the CI on GitHub due to
a time out error by Hypothesis.
