v0.9.1 Bugfixes, better tests and documentation
This minor version includes:
* A new, better documentation based on pkgdown (using several vignettes to explain the various options and mechanisms, rather than a single Readme).
* An improved 'warn' function in the Lua Filter.
* Less warnings in 'R CMD CHECK'.
* A new workflow to automatically run tests whenever a commit is pushed.
* Several bugfixes to make acronymsdown compatible with pandoc 2.17 and higher.
The testing workflow revealed that previous versions were not compatible with pandoc 2.17.0.1.
(This should include pandoc 2.17 as well)
