## What's new in version 5.0
clean-css 5.0 will introduce some breaking changes:
* Node.js 6.x and 8.x are officially no longer supported;
* `transform` callback in level-1 optimizations is removed in favor of new [plugins](#plugins) interface;
* changes default Internet Explorer compatibility from 10+ to >11, to revert the old default use `{ compatibility: 'ie10' }` flag;
* changes default `rebase` option from `true` to `false` so URLs are not rebased by default. Please note that if you set `rebaseTo` option it still counts as setting `rebase: true` to preserve some of the backward compatibility.
And on the new features side of things:
* format options now accepts numerical values for all breaks, which will allow you to have more control over output formatting, e.g. `format: {breaks: {afterComment: 2}}` means clean-css will add two line breaks after each comment
* a new `batch` option (defaults to `false`) is added, when set to `true` it will process all inputs, given either as an array or a hash, without concatenating them.
## What's new in version 4.2
clean-css 4.2 introduces the following changes / features:
* Adds `process` method for compatibility with optimize-css-assets-webpack-plugin;
* new `transition` property optimizer;
* preserves any CSS content between `/* clean-css ignore:start */` and `/* clean-css ignore:end */` comments;
* allows filtering based on selector in `transform` callback, see [example](#how-to-apply-arbitrary-transformations-to-css-properties);
* adds configurable line breaks via `format: { breakWith: 'lf' }` option.
## What's new in version 4.1
clean-css 4.1 introduces the following changes / features:
* `inline: false` as an alias to `inline: ['none']`;
* `multiplePseudoMerging` compatibility flag controlling merging of rules with multiple pseudo classes / elements;
* `removeEmpty` flag in level 1 optimizations controlling removal of rules and nested blocks;
* `removeEmpty` flag in level 2 optimizations controlling removal of rules and nested blocks;
* `compatibility: { selectors: { mergeLimit: <number> } }` flag in compatibility settings controlling maximum number of selectors in a single rule;
* `minify` method improved signature accepting a list of hashes for a predictable traversal;
* `selectorsSortingMethod` level 1 optimization allows `false` or `'none'` for disabling selector sorting;
* `fetch` option controlling a function for handling remote requests;
* new `font` shorthand and `font-*` longhand optimizers;
* removal of `optimizeFont` flag in level 1 optimizations due to new `font` shorthand optimizer;
* `skipProperties` flag in level 2 optimizations controlling which properties won't be optimized;
* new `animation` shorthand and `animation-*` longhand optimizers;
* `removeUnusedAtRules` level 2 optimization controlling removal of unused `@counter-style`, `@font-face`, `@keyframes`, and `@namespace` at rules;
* the [web interface](https://jakubpawlowicz.github.io/clean-css) gets an improved settings panel with "reset to defaults", instant option changes, and settings being persisted across sessions.

## How to process multiple files without concatenating them into one output file?

transform: function (propertyName, propertyValue, selector /* `selector` available since 4.2.0-pre */) {
