Release History

v0.3.0 (18 March 2016)

Implement more sophisticated test filtering, which works well with targeted tests (e.g., "List#empty should have size 0") and with generic tests (e.g., "Users should be able to log out").
Capture more forms of stillborn mutant, including those arising from instances of ScriptError.
Fix bug in which mutation would be repeated if there was more than one subject in a single source file.
Fix bugs in mutations of hash literals and array literals.

## v0.2.8 (22 February 2016)

Prevent insertion operators from incorrectly mutating private and protected keywords.
Fix bugs in mutating overlapping ASTs (by upgrading to metamorpher v0.2.5).

## v0.2.7 (22 February 2016)

Fix bug whereby analysis was incorrectly reusing test results for all previous mutants when evaluating current mutant.

v0.2.6 (17 February 2016)

A mutant's position now carries information about the affected range in the subject, as well as in the mutated code.

v0.2.5 (16 February 2016)

Fix bug in the --cached switch of the score command, which was preventing mutants being correctly loaded from disk on Linux.
Fix bug in the --cached switch of the score command, which was causing mutiny to report the incorrect path to subject files.
Improve extensibility by supporting different implementations of the analyser. This has removed the need to have test selection as an extension point (for now).

v0.2.4 (10 February 2016)

Add --cached switch to the score command, which loads mutants from disk rather than generating them anew.
Various changes to improve extensibility (i.e., mutant storage, test selection) and capabilities (i.e., mutant location and test hooks).

v0.2.3 (26 January 2016)

Add mutation name to each mutant written to disk
Update to Ruby 2.2.3

v0.2.2 (20 January 2016)

Add rudimentary support for stillborn mutants
Better error reporting during mutant generation
Reduce chance that irrelevant subjects are selected for mutation

v0.2.1 (20 August 2015)

Fix #1 - "Uninitialized constant" exception for all commands

v0.2.0 (14 August 2015)

Implement mutiny score mode which performs mutation analysis

v0.1.0 (5 June 2015)

Provide support for:

Running mutation testing commands via the mutiny binary
Checking that a program is amenable to mutation testing
Generating mutants using traditional method-level operators
Integration with RSpec 3
