Monolix 4.2.1 (2013-02-15)
Bugs Fixes:
    - MLXTRAN Project : in STRUCTURAL_MODEL section resolved problem with path relative to %MLXPROJECT%
    - mlxEditor, mlxPerlScript : under Suse Linux OS, conflict with libstdc++ and Qt librairies installed on the OS.
    - Graphics : Kaplan Meier 
        - mean normalization
        - survival curve: case of censured data 
    - simulations where wrong in presence of correlation between individual parameters
    - MLXTRAN Model :
        - Events could be close at a numerical epsilon for the solver, but not for the solver driver
          Rarely, it resulted into an explicit integration failure, returning "NaN"
        - For the simulation of RTTE models, the ordering of the output names had to be alphabetical
        - Not declaring all regression variables that where selected from the data set crashed the application.
        - Declaring some PK without actual doses within the data set raised an error.
        - Using the deprecated syntax with several lagged compartments returned "NaN"
    - Algorithms
    - Error when some subjects had no doses in conditinal mode computation
    - GUI
        - "Display the data" button did not update the information when the dataset was changed after running algorithms
        - Convergence assessment GUI failed when there where only one individual parameter
        - structural models with several dots (.) were not compiled when  clicking in the compile button in the Model selection GUI
        - projects with more outputs in structural model than observations in dataset caused an error when it is loaded
        - the editor was not saved in the preference file
		- Convergence assessment graphics did not handled correctly when there were not variances on some parameters or their covariate dependence
		
Enhancements:
    - add possibility to configure the compiler (used to create Structural Model plugins) through the file 'system.xmlx'
    - user API: 
       - it is possible now to use matlab function "ver" to know Monolix version and Monolix API version
    - mlxEditor:
      - allow multiple files selection on open file dialog box
      - add 'Find and replace'
      - set tabs movable
    - MLXTRAN Model :
        - Continuous observations can be declared within the model.
        - Macro for a depot absorption, with a target ODE component.
    - Permutation kernel for mcmc included
   
Other:
    - Licensing system : '.ini' files desactivated (only the '.lic' files are allowed)
    - residual error models in main interface are shown now with their full name (those used in MLXTRAN project and model)
