## Version 1.0 Changes ##
Our beta release marks our confidence that this library can be used outside of
casual experimenting. To maintain order, we have made a few changes which
current users should read and adapt their code accordingly.

### Renamed functions ###
The following table lists functions which have changed name as of version
1.0.0:

### Miscellaneous ###
 - To match interfaces provided by (all) other quadratic optimization
   libraries, `igl::min_quad_with_fixed` and `igl::active_set` now expect as
   input twice the quadratic coefficients matrix, i.e. the Hessian. For
   example, `igl::min_quad_with_fixed(H,B,...)` minimizes $\frac{1}{2}x^T H
   x+x^T B$.
 - We have inverted the `IGL_HEADER_ONLY` macro to `IGL_STATIC_LIBRARY`. To
   compile using libigl as a header-only library, simply include headers and
   libigl in the header search path. To link to libigl, you must define the
   `IGL_STATIC_LIBRARY` macro at compile time and link to the `libigl*.a`
   libraries.
 - Building libigl as a static library is now more organized. There is a
   `build/` directory with Makefiles for the main library (`Makefile`) and each
   dependency (e.g. `Makefile_mosek` for `libiglmosek.a`)
 - `igl::polar_svd` now always returns a rotation in `R`, never a reflection.
   This mirrors the behavior of `igl::polar_svd3x3`.  Consequently the `T`
   part may have negative skews.
 - We have organized the static
 - The previous `igl::grad` function, which computed the per-triangle gradient
   of a per-vertex scalar function has been replaced. Now `igl::grad` computes
   the linear operator (previous computed using `igl::gradMat`). The gradient
   values can still be recovered by multiplying the operator against the scalar
   field as a vector and reshaping to have gradients per row.
 - `MASSMATRIX_*` has become `MASSMATRIX_TYPE_*`
 - The function `igl::project_normals`, which cast a line for each vertex of
   mesh _A_ in the normal direction and found the closest intersection along
   these lines with mesh _B_, has been removed.
