+# `odcr` changelog
+
+## 0.0.2 (in development)
+
+This release implements additional `xarray` features_
+
+**Features:**
+
+- `xarray` native S3 methods for assigning/replacing variables (see `?odcr::Extract`)
+
+**Bug fixes:**
+
+- The `xarray` attribute "unit" and the `xarray` name of the first object used in an arithmetic operation are not copied to the resulting `xarray` object anymore but stripped instead.
+
+
+***
+
+## 0.0.1 (pre-release)
+
+This release implements a basic API for interacting with `datacube` and `xarray`.
+
+**Features:**
+
+- basic database connection (see `?odcr::database`)
+- `datacube` core `Datacube` class methods (see `?odcr::datacube`)
+- `datacube` core data discovery methods (see `?odcr::datacube`
+- `datacube` core data loading methods (see `?odcr::datacube`
+- `xarray` `xarray.core.dataarray.DataArray` class and formal S3 definition
+- `xarray` `xarray.core.dataset.Dataset` class and formal S3 definition
+- `xarray` native S3 methods for retrieving dimensions (see `?odcr::dim`)
+- `xarray` native S3 methods for indexing by arbitrary number of dimensions (see `?odcr::Extract`)
+- `xarray` native S3 methods for indexing by variable (see `?odcr::Extract`)
+- `xarray` native S3 methods for indexing by time strings (see `?odcr::Extract`)
+- `xarray` native S3 methods for arithmetic operators (see `?odcr::Arithmetic`)
+- `xarray` native S3 methods for coercing to native spatial classes `raster*` and `stars` (see `?odcr::as`)
+- `xarray` native S3 methods for plotting (see `?odcr::plot`)
+- configuration (see `?odcr::config`)
