   * fixed estimation of constants in linear models
   * determistic exogenous now work when there is more than one such variable
   * fixed recursive estimation
   * fixed OSR
   * fix to interface to Global Sensity Analysis toolbox
   * "simul" and "periods" options are now accepted simultaneously by "stoch_simul"
   * preprocessor no longer crashes when there is an unexpected EOF
   * operator precedence is now correct in macro-processor
   * estimated_params_init and estimated_params_bounds now work in conjunction with correlation of endogenous variables
   * fixed bug in the macro-processor, when the body of a @#for loop is empty
   * fixed memory management bug in the preprocessor related to the filename being parsed
   * fixing bug for mode_compute=5,6
 * build_matlab.m script works on Matlab for Windows 64 bits
 * Structures M_ and options_ are saved in the "_results.mat" output file
 * Structure bayestopt_ is saved in the "_mode.mat" output file
 * Added option "notmpterms" to preprocessor, for disabling computation of temporary terms
 * Macro processor reports the location of @#for or @#if statement when not matched by an @#endfor or an @#endif
 * Many updates to the reference manual for 4.0 (which is not yet finished)
 * All code source is now under a free license (GNU General Public License 3 for most of them)
 * All documentation (including user guide) now licensed under the GNU Free Documentation License 1.3

= Version 4.0.2 =

 * Fixed bugs in Kalman filter and smoother
 * Fixed bug with "corr" statement of "shocks" block
 * Added error message if number of equations differs from number of endogenous variables (except when doing optimal policy computation, or standalone BVAR estimation)
 * Fixed bugs with "dynatype" and "dynasave" commands
 * Fixed name collisions with Matlab functions "sec2hms" and "bicgstab"
 * Fixed some licensing issues
 * Removed obsolete "dr_algo" option
 * Fixed crashes under Octave due to graphics limitations
 * Added error message when model local variables (pound sign expressions) are used outside model scope
 * Included AIM subdirectory in packaging
 * Estimation: modified computation of log(det(invhess)) to solve cases in large models where det(invhess) is smaller than machine precision

= Version 4.0.1 =

== Bugs fixed ==
 * some files are missing in Debian and Ubuntu packages (only affects Matlab users who don't have the Statistics Toolbox) 
 * typo at the top of {{{DiffuseKalmanSmootherH1.m}}} (thanks to Tsu-ting Tim Lin for reporting)
 * call to cumulative normal distribution is broken (thanks to Karl Walentin for reporting)
 * script for building MEX files under Matlab R2008a is broken (thanks to Slim Bridji for reporting)
 * homotopy mode 3 is broken
 * BVAR à la Sims: Dynare doesn't accept integer values for tau and lambda parameters (thanks to Aqua for reporting)

== Improvements ==
 * new solve_algo=4 for computing steady state: similar to solve_algo=2, except that it behaves differently when the Jacobian becomes nearly singular or badly scaled
 * homotopy procedures are more verbose
