Compass 1.0 is now available!

First, let's address the elephant in the room: This release took way to

long. I can give you a list of reasons and excuses, but none of them

really matter. Suffice it to say that if you ever find yourself owning

an open source project that has gone unmaintained for more than a year

like Compass had when I re-engaged with the project, the most prudent

course of action is to shut it down. But I'm way to stubborn for that.

What matters now is how things are going to work going forward.

1. Regular bug fix releases. Compass 1.0 is not perfect. Now that it is

released, we will be shipping regular updates with bug fixes and

fresh browser stats so that your prefixes are always up to date.

You can expect a couple releases per month at a minimum.

2. New features. While compass 1.0 has undergone significant rewrites

and refactoring, it is actually quite devoid of what I would consider

any new significant features since 0.12. Now that it is released and

following semantic versioning, we will be free to release new features.

* Vendor prefixing decisions are now data driven by [caniuse.com data](/help/documentation/tuning-vendor-prefixes/). You tell Compass what percentage of users you want to support and we'll take it from there.

* Compass core library now enables you to [use compass without using the

compass command-line tools](/help/documentation/sass-based-configuration-options/).

* Compass speeds up your project compile times by enabling import-once

importing. Existing projects should add `require "compass/import-once/activate"` to their configuration to enable this. [Documentation](https://github.com/Compass/compass/blob/master/import-once/README.md).

* Sass sourcemap support. Set `sourcemap = true` in your compass

configuration file to enable it.

* Rewritten watcher/compiler. Compass now use's Sass builtin compiler

guaranteeing tighter integration and consistency between the projects.

* Blueprint is removed. Not that you were using it, but if you were it's

now maintained as a [separate plugin](http://compass-blueprint.org/).

* CSS3Pie integration is removed.

* Support for recent CSS Developments:

[Animation](/reference/compass/css3/animation/), [Flexbox](/reference/compass/css3/flexbox/), Official Gradient syntax support, [Input Placeholders](/reference/compass/css3/user_interface/),

* Compass extensions that have Sass files that are not partials will now deliver compiled css files into a subdirectory of the css output folder.

* And [much, much more](/CHANGELOG/).

Compass has been a release candidate for a few weeks now. We've fixed

many bugs, but given the magnitude of the changes here, we expect that

there will be more. If you see something strange, please [file a bug](https://github.com/Compass/compass/issues)! Or better yet, send us a patch :)
