Changes with NeuronStudio 0.9.42

*) Render vertices by order and section. The parent edge is used to determine
   the values.

*) Flash hidden vertices and spines. F3 shortcut key added.

*) Output attachment x,y,z coordinate to spine file. Columns are named
   ATTACH-X, ATTACH-Y, and ATTACH-Z.


Changes with NeuronStudio 0.9.44

*) Display edge order numbers in the 2D window.

*) Remove expiration date (perpetual license).

*) Fix display bug where 'Fit Image' and/or 'Actual Pixels' selected without
   'Center & Limit Image' being active.

*) Fix crash when resize filter selected. Set region of interest (ROI) to 100%
   of the new size.

*) Move gamma correction to the palette sub-menu. Gamma correction factor of 1.7
   and 2.2 available. Also visible in slice view mode.

*) Display spines as ellipses with diameter equal to the head size.

*) Enhance file name sequence detection. Support for arbitrary placement of 
   series numeral.


Changes with NeuronStudio 0.9.46

*) Allow slice viewer to control Z-position of manually added spines and
   measurements.

*) Create interface for controlling the global threshold applied to the volume
   rendering.

*) Fix bug in reading true 16-bit TIFF images.

*) Fix bug in Rayburst code where rays travel outside the image.

*) Allow skipping the generation of the volume rendering if View >> Image not
   checked in the main menu.

*) Allow zooming to 256 times the size of one pixel.

*) Enhance rendering speed of 2D projections, especially for large datasets.


Changes with NeuronStudio 0.9.48

*) Fix slice viewer rendering bug.


Changes with NeuronStudio 0.9.50

*) Fix bug in HOC file format output when multiple somas are present.

*) Implement slice viewer widget.

*) Make automatic tracing procedure more responsive to cancellation.

*) Use random sampling during the tracing procedure for increased performance.

*) Make slice viewer control the Z coordinate of the seed if set in Forward (XY)
   view.

*) Calculate the total dendritic length of the model and display in the Model
   Info dialog box.

*) Disallow adding measurements or manual spines if the user clicks outside the
   boundaries of the region of interest (ROI).

*) Limit the progression of the semi-manual tracing to the boundaries of the
   ROI.

*) Make sure the seed location and slice viewer's current slice are limited to
   the boundaries of the ROI as well.


Changes with NeuronStudio 0.9.60

*) Compile FANN into NeuronStudio.

*) Create interface for creating a new classifier.

*) Create capability to load and save a classifier. Loading makes classifier active.

*) Enable ability to see which classifier is active.

*) Ability to add selected spines as training data to active classifier.

*) If no active classifier use default decision tree-based one.

*) Create interface to edit classifier training data.

*) Allow changing diameter of manually added spines.

*) Update spine loading and saving to allow user defined types.

*) Output new field in spine output with distance to soma.

*) Prevent spheres in node from overtaking frusta in DTS computation.


Changes with NeuronStudio 0.9.62

*) Create recompute spine attachment function and menu command.

*) Handle spaces in spine class names properly (replace with dashes).

*) Fix bug in reading and writing of long spine class names.

*) Add an example classifier to distribution.

*) Prevent spines with no type (invalid) from being added to the current
   classifier.


Changes with NeuronStudio 0.9.64

*) Correct bug in fixed threshold tracing.

*) Allow changing diameter of selected spines.

*) Allow changing diameter of last/current sample.
