slimr 0.4.0

• Updated slimr to be fully compatible with SLiM v4.1 updates
• Changed SLIM_HOME environmental variable to SLIMR_PATH, which now should be
  set with the full path to the SLiM executable, not just the directory containing it
• Updated slim_setup() function which now provides cross-platform automatic installation using conda via the reticulate package. Now it should not be necessary for users to manually install SLiM anymore

And for missed 0.3.0 release:

slimr 0.3.0

• Added slim_auto() function to automatically insert r_template() and r_inline() statement in useful places in a slimr_script, based on computational graph analysis
• Added as_slimr_code() function, which is similar to as_slimr_script(), which converts SLiM code as a character vector into a slimr_script object, but as_slimr_code() returns the code necessary to create the slimr_script instead. this allows copy and pasting the text into the R console or IDE so that it can be subsequently edited and modified.
• Added vignette showing how to create a multispecies model in slimr, and documented the multispecies feature in the documentation for slim_block()
