- Fixed bug occuring when calculating line integrals.

- Cleaned up look by adding different axes style options. Default is crossed axes, xy plane, and xy grid.
- Fixed some transparency issues.
- Fixed but in dot/cross tab where rotating vector inadvertently increased the length.
- Fixed bug on Vector Field tab where changing # grid points did not correctly change distance between each vector.
- Using domain/range menu did not correctly re-graph surface. This has been fixed.
- Added ability on deriv tab to change min/max values for theta.
- Fixed some issues with syncing/unsyncing domain of contour map and domain of 3d surface.

- Version 1.0 designation.
- Colors of some objects have been changed.
- Option to specify number of grid points on vector field has been added.

- Contours tab has been made functional. This includes graphing contours of a surface, the gradient at a point (and associated contour), as well as the option to graph a constraint equation as well.
- Some labels were chopped off in on Windows platform; this has been fixed.
- Symbolic calculation of divergence and curl on vector field panel has been added.
- Domain panel on Deriv panel is now hidded as default.
- Circular domain panel has been slightly reformatted.
- "Net Area" is now invisible as default on Int panel for line integrals.

- Added "Deriv" panel. This provides the ability to visualize slices of surfaces that yield curves that can be used to visualize directional derivatives.
- Symbolic computation of partial derivatives is provided.
- Numerical calculation of gradient and visualization of gradient is provided.
- The ability to change the direction of slices (and hence the direction of the derivative) is added via a slider.

- Acceleration vector was not being computed in certain cases. This has been fixed.

- Added ability to graph both tangent and unit tangent vectors on parametric curves.
- Added ability to graph both acceleration vector on parametric curves.

- Added slider to parametric curve graph to move tangent/normal/binormal vectors interactively.
- Added ability to graph up to 10 points, and connect these points with a line, and/or form a closed loop.
- Added ability to graph rectangular surfaces of form y=g(x,z) and x=h(y,z).
- Added circular domain option for rectangular surfaces.
- Parametric curves did not graph the max value for "t". This has been fixed.

- Added Dot/Cross tab to compute and visualize dot products and cross products.
- Fixed bug where vectors parallel to (0,0,-1) would not graph correctly.

- Added option of graphing xy plane.
- Added functionality to all tangent/normal/binormal vector boxes.
- Changed layout slightly.

- First version with basic functionality. User can graph points, vectors, parametric surfaces, parametric curves, and rectangular surfaces in 3D.
