Changelog for camfort-1.2.0

1.2.0 (Oct 12, 2022)

Meta update to provide a release to tie new platform builds to.

Update to new fortran-src version 0.4.0.
New command: basic-checks, which runs a series of other checks in Simple.hs.
Add max-lines threshold for snippets output, currently 5.
Rename units-compile to units-summarise/summarize.
Bring over same command-line flexibility to units-compile as 'fortran-src -c', can specify multiple files-or-directories.
Use ModGraph functionality to allow units-summarise to build dependency graphs and summarise in build-order.
Search includedir recursively for mod-files, like fortran-src.
Numerous changes to increase strictness and reduce memory usage: use Pipes, avoid constructing needlessly large graphs.

Update to new fortran-src version 0.3.0.
Add array-check, alloc-check, use-check, fp-check and implicit-none features.
- A collection of sanity checks on Fortran code looking for common issues, possible problems or potential inefficiencies.
Introduce a divide-and-conquer methodology for solving units-inference problems, reducing the size of the matrices and taking advantage of SMP where available.
Treat constant-expressions and parameter variables as literals, for units-inference purposes, making it easier to retrofit units annotations onto existing programs.
Add 'units-infer --show-ast' feature, which decorates the displayed AST (internal data structure) with units information on each expression.
Made assorted efficiency improvements to the units solver and other features, especially for large projects with many files.
Add 'units-check --dump-mod-file' feature that lets you view an 'fsmod' file's contents with regard to units info.
Allow override of Fortran version used by parser using -F option.
