    7  * Added Error Subspace Transform Kalman filter (ESTKF) and localized variant LESTKF. In addition a variant of the SEIK filter with symmetric square-root and explicit ensemble transformation is now available. (These filers have been introduced in the paper: "A unification of ensemble square-root filters" by L. Nerger, T. Janjic, J. Schroeter, and W. Hiller to appear in the Monthly Weather Review in 2012. ([http://pdaf.awi.de/files/SEIK-ETKF-ESTKF.pdf accepted manuscript])

    88 * Added support to specify the type of the matrix square root in the SEIK filter. (Cholesky decomposition or symmetric square root based on singular value decomposition. The effects of these square root are also discussed in the paper mentioned above.)
    99 * Revised the internal structure of PDAF to simplify the implementation of additional filters. (See the [AddFilterAlgorithm page about adding a filter algorithm] for details.)
