+## Changes in version 4.5.1

+- Small update to `featureSpectra()` and `chromPeakSpectra()` to allow addition
+  of `chromPeaks()` and `featuresDefinitions()` columns to be added to the
+  `Spectra` output. 
+- Tidied the `xcms` vignette, to order the filtering of features and remove 
+  the outdated normalisation paragraph.In depth discussion on this subject can 
+  be found on `metabonaut`.
