 # Changelog
 All notable changes to this project will be documented in this file.
 
+## v1.1.0 -  2020-11-18  - hourly resolution support and new data handlers
+
+### general:
+* MLAir can be used with 1H resolution data from JOIN
+* new data handlers to use the Kolmogorov-Zurbenko filter and mixed sampling types
+
+### new features:
+* new data handler `DataHandlerKzFilter` to use Kolmogorov-Zurbenko filter (kz filter) on inputs (#195)
+* new data handler `DataHandlerMixedSampling` that can used mixed sampling types for input and target (#197)
+* new data handler `DataHandlerMixedSamplingWithFilter` that uses kz filter and mixed sampling (#197)
+* new data handler `DataHandlerSeparationOfScales` to filter-depended time steps sizes on filtered inputs using mixed sampling (#196)
+
+### technical:
+* bug fix for very short time series in TimeSeriesPlot (#215)
+* bug fix for variable dictionary when using hourly resolution (#212)
+* variable naming for data from JOIN interface harmonised (#206)
+* transformation setup is now separated for inputs and targets (#202)
+* bug fix in PlotClimatologicalSkillScore if only single station is used (#193)
+* preprocessed data is now stored inside experiment and not in the data folder
+
 ## v1.0.0 -  2020-10-08  - official release of new version 1.0.0
