0.4.0 (August 29, 2019)

• ModGraph: parse Fortran files and assemble them into a dependency graph in order to construct automated 'build' plans for analysis and summarisation (e.g. with --make-mods option).
• Change name of compilation to summarisation. Remains as '-c' option.
• Allow multiple files and directories to be specified on command line.
• Search includedir recursively for fsmod files.
• Change format of fsmod-files so that they can contain [ModFile] since multiple Fortran files can be summarised into a single mod file.
• Introduce strictness and NFData dependencies across the board.
• Use Pipes to process large amounts of files in order to control memory usage and more efficiently process things.
• Parsing rules for StructStructures (thanks Raoul Charman)

0.3.0 (June 13, 2019)

• Add partial Fortran2003 support.
• Introduce datatype for BBGr instead of prior type alias for Gr.
  • Now split into three fields: bbgrGr, bbgrEntries and bbgrExits
  • May require refactoring of code to use bbgrGr field where a Gr was expected before.
• Introduce pragmaOffset field for Position, allowing pragmas to specify an apparent file and line-number.
  • May require refactoring of code that uses the Position constructor.
  • Fifth field is Maybe (Int, String), containing a line-offset and a target filename when present.
  • It's designed such that most Position-based transformations are not affected by the pragmaOffset.
  • They may need to preserve the field, though, as it passes through functions.
  • Default value is 'Nothing'.
• Add --show-flows-to/--show-flows-from features
  • Visualise the dataflow use/def chains using GraphViz.
• Add --show-block-numbers feature.
  • Allows user to get AST-block numbers easily in order to use them with the above visualisation features.
• Fix several bugs with dataflow analysis that had accumulated.
• Eliminate StContinue and StEnddo are eliminated during GroupLabeledDo transformations.
  • To be consistent with unlabeled Do.
• Parse and discard C-comments as a convenience feature for when fortran-src must interact with the output of C preprocessors that insert spurious comments.
• Add type propagation into type analysis, annotating every expression with a type.
  • Additional interface: analyseTypesWithEnv to access a list of type errors found.
• Add dimensional information to CTArray and length/kind to TypeCharacter.
• Stricter checking of the grouping transform - if any statements that should be grouped are not grouped, raise an error.
• Support pragmas that alter the current 'filename and position' tracker, often used by preprocessors to help pinpoint original code locations.
  • Uses a relative offset field called 'posPragmaOffset' so that relative measures continue to function correctly.
• Add constant propagation / parameter variable analysis.
• Add -c feature to compile 'fsmod files' with renaming and type info.

0.2.1.1 (May 18, 2018)

• Extend Fortran 95 support
• Extend support for legacy extensions

0.2.1.1 (December 13, 2017)

• Fortran95Experimental module renamed to Fortran95
• No infinite loops due to symlinks.
• Fortran 95 support.
  • AST extended to support more non-standard statements internally.
