v3.0.0...v3.0.1

Removed `noquotes` option

Breaking changes

• refactor: removed noquotes option, defaulting it to true b2fe25b (closes #126)
  Now loader never wraps its output in quotes. Historically noquotes option was needed because other loaders (css-loader, etc.) didn't treated input without quotes correctly. Now these loaders have been updated thus making noquotes option obsolete.

Improvements

• chore(deps): update dependency webpack to v4.35.0 4527866

v2.3.3...v3.0.0

Modernization

What's new

1. loader performance improvements (in case you have many icons in your project)

Internals

1. Migrated to Jest
2. DevDependencies cleanup

Added `encoding` option

This release adds encoding option.

Added `stripdeclaration` option

This release adds stripdeclaration option (see #102 for rationale behind that)

Webpack 2. Removed support for url.dataUrlLimit configuration option

1. Moved tests to webpack 2
2. (breaking) Loader does not take into account url.dataUrlLimit configuration option (in any case, in webpack 2 you cannot specify it). If one wants to specify limit, he should do that by providing limit option to the loader.
3. Travis now tests on Node 4 and 6. We no longer test under Node 0.12.

Added support for specifing data-url limit

1. added limit query parameter and url.dataUrlLimit configuration option. See README for more details.
2. code and tests cleanup
