The namespace of the library were split in NumCosmo and NumCosmoMath. All general purpose mathematical and statistical functions/objects are in the NumCosmoMath (Ncm) namespace and all cosmological functions/objects in NumCosmo (Nc).
The make command "make check" now works in every tested system (i586 x86_64) and (Arch Linux, openSUSE

Distance posteriors from WMAP9 data were implemented. For details see http://arxiv.org/abs/1212.5226 (table 11).

Added a new example to the homepage: ( http://www.nongnu.org/numcosmo/#ExampleRGSNIABaoPython ).
In this example we show how to calculate the confidence region of two parameters using the Likelihood Ratio object ( http://www.nongnu.org/numcosmo/manual/NcmLHRatio2d.html ), using both the likelihood ratio test and the Fisher matrix.

Added support to Supernova Ia with non diagonal covariance matrices to the library. In this new model the phenomenological parameters alpha, beta, sigma_int, etc can be analyzed together with the cosmological parameters. This allows analysis similar to what is done, for example, in Conley 2011 ( http://arxiv.org/abs/1104.1443 ). [...]

Several objects translated to Object framework:
- NcmData - Base data object
- NcmDataset - Dataset object
- NcmDataGauss - Gaussian data -- Inverse covariance matrix
- NcmDataGaussDiag - Gaussian data -- Diagonal covariance
