The update to version 1.5 is rather substantial, and introduces some minor
backward-incompatibilities:
* The header "#!symbols" has been replaced by "#!virtual_fields"
* Multiplying polynomials using the '*' symbol is no longer supported (or,
rather, the symbolic capabilities of meankondo were enhanced, and the
syntax has been changed).
* 'meantools exp' has been removed (its functionality is now handled by
other means)
* 'meantoolds derive' has been replaced by 'meantools differentiate'
* The symbolic capabilities were enhanced: polynomials can now be
multiplied, added, exponentiated, and their logarithms can be taken
directly in the configuration file.
* The flow equation can now be processed after being computed using the
various "#!postprocess_*" entries.
* Deprecated kondo_preprocess.
* Compute the mean using an LU decomposition if possible.
* More detailed checks for syntax errors in configuration file.
* Check that different '#!group' entries are indeed uncorrelated.
* New flags in meankondo: '-p' and '-A'.
* New tool: meantools expand.
* Improve conversion to LaTeX using meantools-convert
* Assign terms randomly to different threads.
* Created vim files to implement syntax highlighting for configuration
files.
* Multiple bug fixes
