 # You need to tell CMake where to find the ROOT installation. This can be done in a number of ways:
 # - ROOT built with classic configure/make use the provided $ROOTSYS/etc/cmake/FindROOT.cmake
 # - ROOT built with CMake. Add in CMAKE_PREFIX_PATH the installation prefix for ROOT

+# v1.10.0.8
+
+## New features:
+
+  1. Add `split_chunks` and `split_groups` Functions for `ostap.trees.data_utils.Files` objects to split a large collection sof files into smaller chunks 
+  1. Add `merge_chunks` and `merge_groups` Functions for `ostap.trees.data_utils.Data` objects to perform a partial merging 
+    of ROOT files in the large collections  
+  1. improve `hadd` function from `ostap.utils.utils` module 
+  1. add `mtime` fnuction into `ostap.utils.basic` module - last createion/modification date for the path (dir/file)
+  1. add (much) better cleanup of the ancient tmp directories. Usefulto remove lefovers from the parallel executions.  
+  1. some improvements for `SimFuit.generate`
+  1. fix clang++ bugs&warnings    
+
+## Backward incompatible: 
+
+  1. move `hadd` function from  `ostap.trees.data_utils.Files` to `ostap.trees.data_utils.Data`
+  1. require `nEvents` argument for `SimFit.generate` to be `dict`-like type 
+
+## Bug fixes:
+
+  1. fix numerous typos in documentation strings 
+  1. fix `SimFit.generate`
