+# 2.13.12
+Recoded EventManager to handle correctly events in multiple views.   
+New MATLAB/Python API:
+- change_sig_prop()/anywave('change_sig_prop')  to change properties of several channels at once.   
+- ica_command()/anywave('ica_command') to reject or undo rejection of several ICs at once.   
+
+EDF Plugin:   
+fixed a bug when writing to EDF:  date and time were not correctly written.   
+
+# 2.13.11   
+Recoded 3DViewer organization.  
+3D widget is now in a splitter with a settings widget.    
+Fixed issues in VTK rendering of ScalarBarWidget.    
+Recoded mapping layer to handle correctly bipolar channels loaded directly from data file.   
+Fixed a bug in 3DViewer that was not correctly handling the mapping of bipolar channels.   
+ICA 3D mapping also fixed: now channels identified in the data file are correctly mapped to the 3D viewer.   
+MATLAB:   
+when using settings.json or user.json to set the default MATLAB path and MATLAB Runtime path,   
+the paths are now correctly added to the environment variables before launching the MATLAB process.    
+This is specific to Windows.   
+Windows : switch to VTK version 9.5    
+
+# 2.13.10  
+Python venv were not detected at startup.   
+Now AnyWave will look for python virtual environments in the AnyWave/Plugins/Python/venv folder.   
+Previously saved python venvs are now automatically detected and used.   
+Python plugin can now specify the virtual environment to use by adding venv=alias in desc.txt file.   
+Preferences for Python have been fixed and now correclty handle the options.   
+User can pick a default virtual environment to use.    
+If no venv has been specified, AnyWave will use the default python installation on the system.   
+
+# 2.13.9
+AnyWave now creates a subfolder in AnyWave/Plugins/Python called venv.   
+this folder is used to store the python virtual environment used by AnyWave.   
+Fixed a bug in export wizard about downsampling options:   
+When setting to a factor of 4 on a factor 2 was applied.   
+Now donwsampling by 4 is really applied. 
+Spectral plugin:   
+The plugin was not taking into account the time selection and/or artefact to skip when computing the PSD.   
+Now it does.   
+Added a help menu option to directly open the AnyWave documentation in the browser.    
+Changed the documentation URL to point to the new AnyWave documentation website in About Dialog   
+
+
+# 2.13.8   
+Added the possibility to add custom predefined markers when in mapping mode.   
+ 
+# 2.13.7   
+fixed a bug in the OPM plugin that was not reading the data correctly.   
+fixed a bug in Spectral plugin where rounding the number of points was not done correctly (floor instead of ceil).   
+added back the colorbar display in TFWavelet plugin (was removed in 2.13.6).   
+
 # 2.13.5   
 Now when saving data to MATLAB format, Epochs are considered.   
 If you export data based on markers of same duration, the MATLAB file will contain a tensor matrix containing the data.
