  - Options `solve_algo=7` and `stack_solve_algo=2` now work under Octave
 
- - The macroprocessor now accepts empty arrays, with the `[]` syntax (#707) 
-
  - Added JSON output to the preprocessor. A representation of the model file and the whole content of the `*.mod` file is saved in `*.json` files. These JSON files can be easily parsed from any language (C++, Fortran, Python, Julia, Matlab, ...). This new feature opens the possibility to develop alternative back-ends for the Dynare language.
 
  - Added the possibility to declare Dynare command options in the mod file.
