1.4.1 (2013/10/16)

• fixed battery package 
• bug fixes 

1.4.0 (2013/04/18)

1.2.5 (2012/01/03)

1.2.4 (2011/09/07)

• see Milestone 1.2.4 on github 

1.2.3 (2011/08/23)

• fixed an issue running on MacOS 10.5
• fixed several GUI bugs and improved usability

• added the structure path to the path mapping (for cluster execution)
• change the image path for already scanned structures loaded from pickle files (bug fix)
  

1.2.1 (2011-04-12)

• changed image import strategy: file info and meta data are loaded only for one plate at a time to reduce memory consumption, changed structure file to Python pickle again
• added progress dialog when plates are changed (higher delay due to dynamic loading)
• fixed overwrite of rendering channels with same name (problem between physical and logical channels)

• fixed channel selection problem
  

1.1.2 (2011/01/28)

• fixed bugs in learning SVM classifier
• added "Show Object Contours" shortcut to the browser
• improved speed for 32bit Windows (VC9 whole program optimization)
  

1.1.1 (2011/01/24)

• enhanced the browser (look-up tables, faster rendering, support for multiple channels and object regions)
• fixed a bug in setting primary features
• fixed a bug in feature normalization (regularization for constant features) 
  
• changed SVM training to list-use (no zero-insert required)

• redesign of input image scan (save structure file as compressed text in input path)
• added support for gallery images of events (sequence of object images per event and branch)
• added support for full feature export of events
• reactivated cluster support, added "batch size" for experiments with very high number of positions (and no time-lapse)
