Changes that might impact existing code
Eigen 3.3 fixes a few shortcomings that might impact existing code:
* Eigen 3.3 clarifies the usage of the Index type in SparseMatrix,
PermutationMatrix, Transpositions, as detailed below.
* The normalize and normalized methods will now leave their input
unchanged if its norm is 0 or too close to 0. Previously this
resulted in a vector containing NaNs or infinities.
* internal::significant_decimals_impl is deprecated and users of
custom scalar types are encouraged to overload
NumTraits<>::digits10().
In Eigen 3.3, the evaluation mechanism of expressions has been
completely rewritten. c.f. http://eigen.tuxfamily.org/index.php?title=3.3
Looks as though C++11 support was added and Eigen 2 support removed.

Eigen 3.2.1
Released on February 26, 2014
Changes since 3.2.0:
* Eigen2 support is now deprecated and will be removed in version
3.3.
* Core:
+ Bug fix for Ref object containing a temporary matrix.
+ [146]Bug 654: Allow construction of row vector from 1D array.
+ [147]Bug 679: Support cwiseMin() and cwiseMax() on maps.
+ Support conservativeResize() on vectors.
+ Improve performance of vectorwise and replicate expressions.
+ [148]Bug 642: Add vectorization of sqrt for doubles, and make
sqrt really safe if EIGEN_FAST_MATH is disabled.
+ [149]Bug 616: Try harder to align columns when printing
matrices and arrays.
+ [150]Bug 579: Add optional run-time parameter to fixed-size
block methods.
+ Implement .all() and .any() for zero-sized objects
+ [151]Bug 708: Add placement new and delete for arrays.
+ [152]Bug 503: Better C++11 support.
* Dense linear algebra:
+ [153]Bug 689: Speed up some matrix-vector products by using
aligned loads if possible.
+ Make solve in FullPivHouseholderQR return least-square
solution if there is no exact solution.
+ [154]Bug 678: Fix fullPivHouseholderQR for rectangular
matrices.
+ Fix a 0/0 issue in JacobiSVD.

setFromTriplets().
+ Fixes in SparseLU: infinite loop, aliasing issue when solving,
overflow in memory allocation, use exceptions only if enabled
([159]bug 672).
+ Fixes in SparseQR: reduce explicit zero, assigning result to
map, assert catching non-conforming sizes, memory leak.
+ [160]Bug 681: Uninitialized value in CholmodSupport which may
lead to incorrect results.
+ Fix some issues when using a non-standard index type ([161]bug

+ MacOS put OpenGL header files somewhere else from where we
expected it.
+ Do not assume that alloca() is 16-byte aligned on Windows.

+ Fix Fortran compiler detection in CMake files.
* Fix some of our tests (bugs [162]744 and [163]748 and more).
* Fix a few compiler warnings (bug [164]317 and more).
* Documentation fixes (bugs [165]609, [166]638 and [167]739 and
more).
