0.8.0

• New image comparison algorithm is implemented:
  • gm compare replaced with custom diff. For now, GraphicsMagick
    is still required for other image manipulations.
  • tolerance setting is removed in favor of "strict mode": by default,
    only noticable changes (according to ciede2000 metric) will be treated
    as failure, to treat all changes that way user can enable
    strictComparison option.
  • in case if some element in focus during test can potentially have
    blinking caret displayed, diff will try to ignore caret.
• Remove built-in TeamCity reporter. If you really want
  it, you can adapt 0.7.x reporter to the current version
  of gemini and publish it in separate package.
• Remove legacy ability to specify browsers as array which
  was deprecated since 0.4.0.
• Add experimental programmatic API.
• Add --grep option to gather and test commands, which
  allows to execute only suites, matching the pattern (@scf2k).
• Show required dimensions in error message when origin does
  not fir to full-page screenshot (@scf2k)

0.7.0

• Show meaningful error when capture area origin
  does not fit to full-page screenshot. This change
  can break some of your tests (@scf2k).
• Add experimental CSS-coverage report. Enable
  with --coverage CLI flag or coverage: true in
  config (@scf2k).
• Add ability to override gridUrl,rootUrl, screenshotsDir,
  debug config options by their respective CLI options or
  environment variables (@arikon).
• Add config option windowSize to specify default
  size of the browser windows (@scf2k).
• Add action setWindowSize to specify browser
  window size during the tests (@scf2k).

0.6.5

Was republished as 0.7.0 due to a breaking change.

0.6.4

• Add command line completion (@unlok).
• Show an error, when config file has unknown
  options.
• Add focus(element) action (@arikon).

0.6.3

• Allow to use empty string with sendKeys. It can be used
  to focus on an element without changing states.

0.6.2

• Reset mouse position for each suite. Previously, cursor
  may stay at the position left from a previous suite and
  some elements was captured with hover effect when there
  shouldn't be any.

0.6.1

• Fix incorrect capture region rounding, causing bottom row
  of the element to be cropped sometimes.

0.6.0

• :before and :after pseudo-elements outline and shadow are now
  taken into account when calculating capture region(@incorp).

  This change can break some of your tests. Re-gather reference images
  to fix the problem.

• Added tolerance config option which can be used to specify maximum
  error rate before images will be treated as unequal.
  Default tolerance to 0. This is stricter then previous versions:
  now every, even slightest difference between reference and current
  images will fail tests.

  Set tolerance to 0.001 in .gemini.yml to restore 0.5.x behavior.

• Coordinates of capture region are now rounded to capture maximal area.
  Previously, border pixels could be cropped, due to rounding error.
  This change can break some of your tests. Re-gather reference images
  to fix the problem.

• Added ability to change diff highlight color in config file.

• Change diff highlight style

• Global installations of gemini now runs local one, if available.

0.5.0

• Browsers are now launched once for each run (previously, they were
  launched once per suite). This greatly reduces total tests run time,
  but can break some of your code, i.e. each mouseDown should always
  be closed by mouseUp.
  Previously, this was not required if mouseDown was used once for
  suite.
  It will show warning if versions of the modules does not match.
• flat reporter replaces tree. Tree reporter can not work with new
  browser launch model.
• Add parallelLimit option that allows to limit number of browsers
  run in parallel.
• Add suite.after() which can be used to perform some action after all
  of the states without taking screenshot.
• Unknown errors, returned by Selenium have more detailed report.
• Fix --version option.

0.4.2

• Fix missing images in html report.
