 ### Changelog:
+RStoolbox 0.2.4
+====================================
+New:
+
+* function `oneHotEncode()`: splits a single rasterLayer into multiple layers (one per class)
+  with one-hot encoding, i.e. pixel value = 1 for matches, pixel value = 0 for all other classes (background).
+* `ggR()` can now display more than one layer. Each layer can be plotted to a subplot in a multi-panel grafic.
+* `encodeQA()`, `decodeQA()` and `classifyQA()` can now deal with the new QA format introduced with Landsat Collection data. Legacy QA designations can still be interpreted by setting the `legacy` argument.
+* new `predict()` method for unsupervised classification models (`unsuperClass`).
+
+Changes: 
+* all `radCor()` DOS methods now work for Landsat 8 OLI
+
+Fixes:
+* fix `unsuperClass()` for algorithms other than Hartigan-Wong (reported by Alex Ilich)
