# What’s New in *GetFEM++* 1.6¶

Released, 2004/01/23:

GetFEM++1.6 is mostly a bugfix and performance improvements release:

- Some new integration methods were added (high order methods for triangles such as
`IM_TRIANGLE(19)`

from P. Solin, K. Segeth and I. Dolezel:Higher-Order & Finite Element Methods, Chapman & Hall/CRC Press, 2003).- Performance of interpolation and geometric transformation inversion was much improved.
- Support for emc2 meshes.
- The Gmm++ library has been much improved version 1.6 and version 1.5. We have especially focused on its robustness:

- Many bugs were fixed, especially for complex matrices.
- QR algorithms were introduced for dense matrices.
- A LAPACK/ATLAS interface is available.
- SuperLU 2.0 interface.
- Small simplification in
`linalg_traits`

structure.- Generic resize procedures for vector and matrices were introduced.
- It is possible to use a column or row matrix view of a vector with
`gmm::row_vector`

and`gmm::col_vector`

.- Generic
`gmm::reshape`

and`gmm::conjugated`

functions.- Intensive tests with random type of matrices and vectors.
