[full changelog](https://github.com/Mange/roadie/compare/v3.4.0...master)
Nothing yet.
### 3.5.0
[full changelog](https://github.com/Mange/roadie/compare/v3.4.0...v3.5.0)
* Drop support for Nokogiri before 1.8.
### 3.4.0
[full changelog](https://github.com/Mange/roadie/compare/v3.3.0...v3.4.0)
* Enhancements
* Better support for media queries - [BroiSatse (Stanislaw
Klajn)](https://github.com/BroiSatse) and [jeznag (Jeremy
Nagel)](https://github.com/jeznag) (#157).
Media queries should no longer be inlined in your HTML; instead they should
appear in `` if `keep_uninlinable_css` is enabled. By default different
media query blocks with the same conditions will be merged together (which
might change specificity), but this behavior can be disabled by setting
`merge_media_queries` to `false`.
* Remove Guard as a development dependency. Tests run fast anyway, and I
never liked that this tool "infected" the dependencies of the project when
it should remain a user-specific tool unless the project wants to enforce
it.
### 3.3.0
[full changelog](https://github.com/Mange/roadie/compare/v3.2.2...v3.3.0)
* Enhancements

* Support partial HTML documents (fragments) - #147
* With the help of [andfx](https://github.com/andfx) - #115
* With the help of [Frida Sjoholm](https://github.com/FridaSjoholm) - #146
* Skip URL rewriting on elements with `data-roadie-ignore` - #154.
* With the help of [Hamed Asghari](https://github.com/hasghari) - #138.
* Bug fixes:
* Apply correct string encoding / charset in `NetHttpProvider` - [Jeremy Nagel](https://github.com/jeznag) (#152).
### 3.2.2
[full changelog](https://github.com/Mange/roadie/compare/v3.2.1...v3.2.2)
* Enhancements

### 3.2.1
[full changelog](https://github.com/Mange/roadie/compare/v3.2.0...v3.2.1)

### 3.2.0
[full changelog](https://github.com/Mange/roadie/compare/v3.1.1...v3.2.0)

* Dropped support for MRI 2.0.
* Upgrades:
* Use `css_parser` 1.4.x instead of 1.3.x.
* Bug fixes:
* Strip UTF-8 BOM (Byte Order Mark) from stylesheets before parsing / concatenating - [Bartłomiej Wójtowicz](https://github.com/qbart) (#128)
* Enhancements:
* Build against Ruby MRI 2.3.0 too.
* Don't add extra whitespace between table cells.
### 3.1.1
[full changelog](https://github.com/Mange/roadie/compare/v3.1.0...v3.1.1)
* Enhancements:
* Duplicate style properties are now removed when inlining.
* This means that `color: green; color: red; color: green` will now be `color: red; color: green`.
* The size of your emails should be the same, or smaller.
### 3.1.0
[full changelog](https://github.com/Mange/roadie/compare/v3.1.0.rc1...v3.1.0)
* Enchancements:
* `NetHttpProvider` validates the whitelist hostnames; passing an invalid hostname will raise `ArgumentError`.
* `NetHttpProvider` supports scheme-less URLs (`//foo.com/`), defaulting to `https`.
### 3.1.0.rc1
[full changelog](https://github.com/Mange/roadie/compare/v3.0.5...v3.1.0.rc1)
* Enhancements:
* Allow user to specify asset providers for referenced assets with full URLs and inline them (#107)
* Pass `Document` instance to transformation callbacks (#86)
* Made `nokogiri` dependency more forgiving.
* Supports `1.5.0`...`1.7.0` now instead of `1.6.0`...`1.7.0`. Some people out there are stuck on this older version of Nokogiri, and I don't want to leave them out.
* Output better errors when no assets can be found.
* The error will now show which providers were tried and in which order, along with the error message from the specific providers.
* `Roadie::FilesystemProvider` shows the given path when inspected.
* `data-roadie-ignore` attributes will now be removed from markup; hiding "development markers" in the final email.
* Add a `Roadie::CachedProvider` asset provider that wraps other providers and cache them.
* Add a `Roadie::PathRewriterProvider` asset provider that rewrites asset names for other providers.
* This saves you from having to create custom providers if you require small tweaks to the lookup in order to use an official provider.
* **Deprecations:**
* `Roadie::Stylesheet#each_inlinable_block` is now deprecated. You can iterate and filter the `blocks` at your own discresion.
### 3.0.5
[full changelog](https://github.com/Mange/roadie/compare/v3.0.4...v3.0.5)
* Bug fixes:
* Don't try to inline external stylesheets. (#106)
* Don't generate absolute URLs for anchor links. (Mange/roadie-rails#40)
### 3.0.4
[full changelog](https://github.com/Mange/roadie/compare/v3.0.3...v3.0.4)
* Bug fixes:
* Schemeless URLs was accepted as-is, which isn't supported in a lot of email clients. (#104)
### 3.0.3
[full changelog](https://github.com/Mange/roadie/compare/v3.0.2...v3.0.3)
* Bug fixes:
* CSS was mutated when parsed, breaking caches and memoized sources - [Brendan Mulholland (bmulholland)](https://github.com/bmulholland) (Mange/roadie-rails#32)

* Enhancements:
* `CssNotFound` can take a provider which will be shown in error messages.

* URL rewriter no longer raises on absolute URLs that cannot be parsed by `URI`. Absolute URLs are completely ignored.
* URL rewriter supports urls without a scheme (like `//assets.myapp.com/foo`).
* URL rewriter no longer crashes on absolute URLs without a path (like `myapp://`).
### 3.0.0
[full changelog](https://github.com/Mange/roadie/compare/v3.0.0.pre1...v3.0.0)
* Enhancements:
* `Roadie::ProviderList` responds to `#empty?` and `#last`
* `Roadie::FilesystemProvider` ignores query string in filename.
Older versions of Rails generated `` tags with query strings in their URLs, like such:
`/stylesheets/email.css?1380694096`
* Blacklist `:enabled`, `:disabled` and `:checked` pseudo functions - [Tyler Hunt (tylerhunt)](https://github.com/tylerhunt).
* Add MRI 2.1.2 to Travis build matrix - [Grey Baker (greysteil)](https://github.com/greysteil).
* Try to detect an upgrade from Roadie 2 and mention how to make it work with the new version.
* Styles emitted in the `style` attribute should now be ordered as they were in the source CSS.
### 3.0.0.pre1
[full changelog](https://github.com/Mange/roadie/compare/v2.4.2...v3.0.0.pre1)
Complete rewrite of most of the code and a new direction for the gem.
* Breaking changes:
* Removed Rails support into a separate Gem (`roadie-rails`).
* Removed Sprockets dependency and AssetPipelineProvider.
* Changed the entire public API.
* Changed the API of custom providers.
* Dropped support for Ruby 1.8.7.
* Change `data-immutable` to `data-roadie-ignore`.
* New features:
* Rewriting the URLs of `img[src]`.
* A way to inject stylesheets without having to adjust template.
* A before callback to compliment the after callback.
* Enhancements:
* Better support for stylesheets using CSS fallbacks.
This means that styles like this is now inlined: `width: 5em; width: 3rem;`, while Roadie would previously remove the first of the two.
This sadly means that the HTML file will be much larger than before if you're using a non-optimized stylesheet (for example including your application stylesheet to the email). This was a bad idea even before this change, and this might get you to change.
* Using HTML5 doctype instead of XHTML
* Full support for JRuby
* Experimental support for Rubinius
### 2.4.2
[full changelog](https://github.com/Mange/roadie/compare/v2.4.1...v2.4.2)
* Bug fixes:
* Fix Nokogiri version to allow only 1.5.x on ruby 1.8.7
* Blacklist :before, :after, :-ms-input-placeholder, :-moz-placeholder selectors – [Brian Bauer (bbauer)][https://github.com/bbauer].
* Build failed on 1.8.7 due to a change in `css_parser`
### 2.4.1
[full changelog](https://github.com/Mange/roadie/compare/v2.4.0...v2.4.1)
* Bug fixes:
* Allow Nokogiri 1.5.x again; 1.6.x is unsupported in Ruby 1.8.7.
### 2.4.0
[full changelog](https://github.com/Mange/roadie/compare/v2.3.4...v2.4.0)
* Enhancements:
* Support Rails 4.0, with the help of:
* [Ryunosuke SATO (tricknotes)](https://github.com/tricknotes)
* [Dylan Markow](https://github.com/dmarkow)
* Keep `!important` when outputting styles to help combat web mail styles being `!important`
* Support `:nth-child`, `:last-child`, etc.
* To make this work, Roadie have to catch errors from Nokogiri and ignore them. A warning will be printed when this happens so users can open issues with the project and tests can be expanded.
* Support for custom inliner (#58) — [Harish Shetty (kandadaboggu)](https://github.com/kandadaboggu) with friends
* Bug fixes:
* Don't crash when URL options have protocols with "://" in them (#52).
* Other:
* Be more specific on which versions are required; require newer `css_parser`
* Officially support MRI 2.0.0
