+# Changelog
+All notable changes to this project will be documented in this file.
+
+## v0.9.0  -  2020-04-15  -  faster bootstraps, extreme value upsamling
+### general
+- improved and faster bootstrap workflow
+- new plot PlotAvailability
+- extreme values upsampling
+- improved runtime environment
+
+### new features
+- entire bootstrap workflow has been refactored and much faster now, can be skipped with `evaluate_bootstraps=False`, #60
+- upsampling of extreme values, set with parameter `extreme_values=[your_values_standardised]` (e.g. `[1, 2]`) and 
+  `extremes_on_right_tail_only=<True/False>` if only right tail of distribution is affected or both, #58, #87
+- minimal data length property (in total and for all subsets), #76
+- custom objects in model class to load customised model objects like padding class, loss, #72
+- new plot for data availability: `PlotAvailability`, #103
+- introduced (default) `plot_list` to specify which plots to draw
+- latex and markdown information on sample sizes for each station, #90
+
+### technical
+- implemented tests on gpu and from scratch for develop, release and master branches, #95
+- usage of tensorflow 1.13.1 (gpu / cpu), separated in 2 different requirements, #81
+- new abstract plot class to have uniform plot class design
+- New time tracking wrapper to use for functions or classes
+- improved logger (info on display, debug into file), #73, #85, #88
+- improved run environment, especially for error handling, #86
+- prefix `general` in data store scope is now optional and can be skipped. If given scope is not `general`, it is 
+  treated as subscope, #82
+- all 2D Padding classes are now selected by `Padding2D(padding_name=<padding_type>)` e.g. 
+  `Padding2D(padding_name="SymPad2D")`, #78
+- custom learning rate (or lr_decay) is optional now, #71
