### [ [>](https://github.com/svg/svgo/tree/v0.5.5) ] 0.5.5 / 05.08.2015

### [ [>](https://github.com/svg/svgo/tree/v0.5.4) ] 0.5.4 / 05.08.2015

* New parameter `useShortTags` by @bradbarrow. Now svgo can produce correct non-selfclosing tags (useful in HTML in old browsers).

* Fixed failing on empty transformation (which could be produced by two opposite).

* Fixed removing paths which have numbers with exponent notation.

### [ [>](https://github.com/svg/svgo/tree/v0.5.3) ] 0.5.3 / 21.06.2015

* Fixed breaking related to rounding functions in “[convertTransform](https://github.com/svg/svgo/blob/master/plugins/convertTransform.js)”.

* Fixed a bug with ID in animations not being worked on by “[cleanupIDs](https://github.com/svg/svgo/blob/master/plugins/cleanupIDs.js)”.

* Fixed a bug with quoted reference in `url()`.

* Now, if there are several same IDs in the document, then the first one is used and others are being removed.

* New command-line option `--show-plugins` displaying list of plugins.

* Two new optional plugins: “[removeDimensions](https://github.com/svg/svgo/blob/master/plugins/removeDimensions.js)” (removes `width` and `height` if there is `viewBox`) and “[removeAttrsPlugin](https://github.com/svg/svgo/blob/master/plugins/removeAttrs.js)” (by @bennyschudel).

### [ [>](https://github.com/svg/svgo/tree/v0.5.2) ] 0.5.2 / 24.05.2015

* Introduced new `transformPrecision` option for better image quality (defaults to 5) in “[convertTransform](https://github.com/svg/svgo/blob/master/plugins/convertTransform.js)” and “[convertPathData](https://github.com/svg/svgo/blob/master/plugins/convertPathData.js)” (for the purpose of applying transformations) plugins.

* Matrix transformations now can be decomposed into a combination of few simple transforms like `translate`, `rotate`, `scale`.

* Arcs (paths `arcto` command) are now correctly being transformed into another arcs without being converting to Bezier curves.

* Fixed an issue with “[mergePaths](https://github.com/svg/svgo/blob/master/plugins/mergePaths.js)” failing to detect paths intersection in some cases.

* Fixed a bug with “[removeUnknownsAndDefaults](https://github.com/svg/svgo/blob/master/plugins/removeUnknownsAndDefaults.js)” removing some paths, which was introduced in [v0.5.1](https://github.com/svg/svgo/tree/v0.5.1).

* Fixed a bug with transformation having `rotate()` with optional parameters.

* Patterns with inherited attributes are no longer being removed.

* Styles are no longer being removed from `<desc>` (by @dennari).

* Added `clone()` method to JSAPI (by @jakearchibald)

### [ [>](https://github.com/svg/svgo/tree/v0.5.1) ] 0.5.1 / 30.03.2015

* added new command-line option to set precision in floating point numbers.

* Notably [mergePaths](https://github.com/svg/svgo/blob/master/plugins/mergePaths.js) plugin now checks for possible intersections to avoid side-effects

* new plugin [removeUselessDefs](https://github.com/svg/svgo/blob/master/plugins/removeUselessDefs.js) to remove elements in ``<defs>`` and similar non-rendering elements without an ``id`` and thus cannot be used

* fix for ``--multipass`` command line option (by @dfilatov)

* improved [cleanupEnableBackground](https://github.com/svg/svgo/blob/master/plugins/cleanupEnableBackground.js) and [convertColors](https://github.com/svg/svgo/blob/master/plugins/convertColors.js) plugins (by @YetiOr)

* new plugin for image manipulation [cleanupListOfValues](https://github.com/svg/svgo/blob/master/plugins/cleanupListOfValues.js) (by @kiyopikko)

* fixed fail on comments after closing root ``</svg>`` tag

* updated parsing to account meaningful spaces in ``<text>``

* ``data-*`` attributes are now preserved in [removeUnknownsAndDefaults](https://github.com/svg/svgo/blob/master/plugins/removeUnknownsAndDefaults.js)

* prevented plugins from failing in ``<foreignObject>``

* [cleanupNumericValues](https://github.com/svg/svgo/blob/master/plugins/cleanupNumericValues.js) plugin now converts other units to pixels (if it's better)

* [removeUselessStrokeAndFill](https://github.com/svg/svgo/blob/master/plugins/removeUselessStrokeAndFill.js) plugin is enabled again with correct work in case of inherited attributes

* fixed fail on images with incorrect paths like ``<path d="z"/>``

* svgo now understands if an input is a folder (remember, you can set output to folder as well)

* added support for some properties from SVG 2 like ``vector-effect="non-scaling-stroke"``

* removed option to remove an ``id`` on root ``<svg>`` tag in [removeUnknownsAndDefaults](https://github.com/svg/svgo/blob/master/plugins/removeUnknownsAndDefaults.js) since it's already being done in [cleanupIDs](https://github.com/svg/svgo/blob/master/plugins/cleanupIDs.js)

### [ [>](https://github.com/svg/svgo/tree/v0.5.0) ] 0.5.0 / 05.11.2014

* added ``--multipass`` command line option which repeatedly applies optimizations like collapsing groups (by @dfilatov)

* exposed JSAPI as a factory method (by @mistakster)

* added removeDesc plugin (by @dwabyick), disabled by default

* [removeUselessStrokeAndFill](https://github.com/svg/svgo/blob/master/plugins/removeUselessStrokeAndFill.js) plugin is disabled by default since it's unable to check inherited properties

* transformations now apply to paths with arcs in [plugins/convertPathData](https://github.com/svg/svgo/blob/master/plugins/convertPathData.js)

* a lot of bug fixes mostly related to transformations

### [ [>](https://github.com/svg/svgo/tree/v0.4.5) ] 0.4.5 / 02.08.2014

* significally improved plugin [plugins/convertPathData](https://github.com/svg/svgo/blob/master/plugins/convertPathData.js):

  - Now data is being written relative or absolute whichever is shorter. You can turn it off by setting ``utilizeAbsolute`` to ``false``.

  - Smarter rounding: values like 2.499 now rounds to 2.5. Rounding now takes in account accumulutive error meaning that points will not be misplaced due to rounding more than it neccessary.

* ``--output`` option now can be a folder along with ``--folder``, thanks to @mako-taco.

* [plugins/cleanupIDs](https://github.com/svg/svgo/blob/master/plugins/cleanupIDs.js) now have ``prefix`` option in case you want to combine multiple svg later (by @DanielMazurkiewicz).

* Quotes now being escaped in attributes (by @ditesh).

### [ [>](https://github.com/svg/svgo/tree/v0.4.4) ] 0.4.4 / 14.01.2014

* new plugin [plugins/removeTitle](https://github.com/svg/svgo/blob/master/plugins/removeTitle.js) (disabled by default, close [#159](https://github.com/svg/svgo/issues/159))

* plugins/convertPathData: skip data concatenation for z instruction in collapseRepeated

* plugins/removeUnknownsAndDefaults: do not remove overriden attributes with default values (fix [#161](https://github.com/svg/svgo/issues/161) and [#168](https://github.com/svg/svgo/issues/168))

* plugins/removeViewBox: disable by default (fix [#139](https://github.com/svg/svgo/issues/139))

* update README with [gulp task](https://github.com/ben-eb/gulp-svgmin)

### [ [>](https://github.com/svg/svgo/tree/v0.4.3) ] 0.4.3 / 02.01.2014

* new plugin [plugins/convertShapeToPath](https://github.com/svg/svgo/blob/master/plugins/convertShapeToPath.js) (close [#96](https://github.com/svg/svgo/issues/96))

* update sax version to fix [#140](https://github.com/svg/svgo/issues/140)

### [ [>](https://github.com/svg/svgo/tree/v0.4.2) ] 0.4.2 / 19.12.2013

* fix `js-yaml` version to suppress deprecation warning in stdout

### [ [>](https://github.com/svg/svgo/tree/v0.4.1) ] 0.4.1 / 18.11.2013

### [ [>](https://github.com/svg/svgo/tree/v0.4.0) ] 0.4.0 / 18.11.2013

### [ [>](https://github.com/svg/svgo/tree/v0.3.7) ] 0.3.7 / 24.06.2013

* do not remove `result` attribute from filter primitives (fix [#122](https://github.com/svg/svgo/issues/122))

* plugins/cleanupAttrs: replace newline with space when needed (fix [#119](https://github.com/svg/svgo/issues/119))

* lib/coa: look for config file in current folder

* lib/coa: always traverse all files in the given folder

* deprecate svgo-grunt in favor of [grunt-svgmin](https://github.com/sindresorhus/grunt-svgmin)

### [ [>](https://github.com/svg/svgo/tree/v0.3.6) ] 0.3.6 / 06.06.2013

* plugins/removeNonInheritableGroupAttrs: more attrs groups to exclude (fix [#116](https://github.com/svg/svgo/issues/116) & [#118](https://github.com/svg/svgo/issues/118))

* lib/coa: optimize folder file by file (temp fix [#114](https://github.com/svg/svgo/issues/114))
