Hi,

Eigen 2.0.11 is released.

The source archive is at:
http://bitbucket.org/eigen/eigen/get/2.0.11.tar.bz2

Changes since 2.0.10:

    * Complete rewrite of the 4x4 matrix inversion: we now use the
usual cofactors approach, so no numerical stability problems anymore
(bug #70)
    * Still 4x4 matrix inverse: SSE path for the float case, borrowing
code by Intel, giving very high performance.
    * Fix crash happening on 32-bit x86 Linux with SSE, when double's
were created at non-8-byte-aligned locations (bug #79).
    * Fix bug in Part making it crash in certain products (bug #80).
    * Precision improvements in Quaternion SLERP (bug #71).
    * Fix sparse triangular solver for lower/row-major matrices (bug #74).
    * Fix MSVC 2010 compatibility.
    * Some documentation improvements.

Cheers,
Benoit
