+# simplerspec 0.1.0.9001
+
+* `resample_spc()` now supports flexible spectra and x-axis types as inputs. Its
+  interface has been carefully augmented without breaking previous 
+  functionality ([#9](https://github.com/philipp-baumann/simplerspec/issues/9)
+  * New argument `column_in` specifies the string or name (unquoting support)
+    of the input column that contains the list of spectra. The following 
+    spectrum types, which are automatically matched against the list-column that
+    contains the corresponding x-unit value vectors, are currently supported:
+    `spc` (raw or unprocessed spectra), `spc_rs` (resampled spectra),
+    `spc_mean` (mean spectra), `spc_nocomp` (spectra prior atmospheric 
+    compensation), `sc_sm` (single channel sample spectra), `sc_rf` (single 
+    channel reference spectra), `spc_pre` (preprocessed spectra).
+  * New argument `interpol_method` specifying the interpolation method is 
+    introduced. Default is `"linear"` to achieve identical results with both
+    prospectr v0.1.0 and v0.2.0. The current CRAN prospectr v0.2.0 has changed
+    the default of `interpol` to `"spline"`. The previous `resample_spc()` 
+    unfortunatelty did not explicitly state the method internally, and relied 
+    on the default instead. The measures taken ensure downward compatibility of 
+    `resample_spc()` with previous versions of prospectr and simplerspec.
+  * The arguments gain more defensive checks inside the function (supplied types
+    and presence of objects in spectra).
+  * The function components and the help are updated accordingly. Clearer 
+    vocabulary to describe the functionality and more consistent terminology for
+    physical quantities and R objects are used.
+  
+* Add UTF-8 support to DESCRIPTION because roxygen2 version 7.1.0 requires it.

-* `model_list` can now also be a list of "train" objects and not only a simplerspec `fit_pls()` output. This saves memory when doing predictions
-* Omit message "Joining..." by explicitly providing `by` argument in `dplyr::inner_join`
-* Ungroup when slicing tibble so that return data frame does not show "Groups:   sample_id [?]" when printing
-* subsequent simplerspec processing functions return (list of) data.table's -> consistency
-* newly planned json import/export API based on jsonlite package can passes column names as fields_id only for data.frames and not matrices
+* Start using Kirill's `{fledge}` for tracking and communicating the simplerspec
+  development process in `NEWS`.
