0.4.0

Allow the :runner option for HandBrake::CLI to take a lambda that returns the runner. (#4)
Document the default runner to make the runner protocol explicit. (#4)
Ensure that arguments that contain quotes are properly escaped during execution. (#2; reported by bmatsuo)

0.3.1

Add :dry_run option for HandBrake::CLI. When true, the commands that would be executed otherwise are printed to standard out instead.
Ensure that the directories needed by a call to HandBrake::CLI#output exist before writing to them.
Ensure that the options hash passed into #output is not modified.

Change the output from the scan action to be a HandBrake::Disc object which contains a titles hash, rather than the hash directly.
When scanning for a single title, return only a single HandBrake::Title.
Accept a path for the :atomic option to HandBrake::CLI#output. If specified, the temporary file will be written to this path rather than the ultimate target directory.
Ensure that trace mode prints updating lines (e.g., the encode status) that do not end in newlines in a timely fashion.
Add property-based constructors to HandBrake::Title and HandBrake::Chapter for easier construction in tests of consuming apps/libs.

Include parent references in HandBrake::Title and HandBrake::Chapter.
When parsing a title scan, do not keep references to the parsed tree in the HandBrake::Title objects.

Change HandBrake::Title#chapters from an Array to a Hash. This is consistent with HandBrake::Titles and obviates the need for index to chapter number conversions. HandBrake::Title#all_chapters is the equivalent of the old HandBrake::Title#chapters method.
