Changelog

v1.0b1 -- 2/22/2017

Added an always_remutate setting which provides the ability to specify assets that should always be remutated (even if a source file change was not detected).
Tweaked the output filename format for mutated files. The new format should be significantly more resistant to edge-case naming collisions when utilizing a remutate_check of exists.
Renamed the (default) mtime value for the remutate_check setting to stat. It now checks both the size and last modified time of the asset source file.
The asset_paths setting has been merged into the each_boot setting. Now instead of receiving a boolean, each_boot must receive a list specifying assets that should be checked/mutated when the application boots.
Renamed the asset_prefix setting to mutated_file_prefix in an effort to be more explicit.

Fixed a bug where mutated files could be created with incorrect filenames if the each_boot setting was enabled with a remutate_check value of mtime or checksum.
Fixed a Windows bug due to shlex.split usage (thanks @tdamsma).
Added a purge_mutated_path setting which can be used to remove all files from a specified mutated_path upon application boot.

Experimental support for template language parsing (e.g. you could use view helpers like request.route_url() in your CoffeeScript by installing the pyramid_jinja2 package and using application.coffee.jinja2 as the asset source filename).
