sbt/notes/1.0.0-M12.markdown

### Changes

* Add support for cross version in `excludeDependencies` in SBT plugin (thanks to [@jalaziz], [#238])
* Add `simple-web-server` module, providing an equivalent of python's `SimpleHTTPServer` or node's `http-server` (run like `./coursier launch io.get-coursier:simple-web-server_2.11:1.0.0-M12 -r http://dl.bintray.com/scalaz/releases`, add `-- --help` to list available options - [#241])
* Fix a resolution bug occurring randomly in some tricky resolutions ([#241])
* Fix Ivy attributes missing in artifacts published from SBT with sbt-coursier enabled (mainly affects SBT plugins published this way, [#241])
* Add support for printing dependency trees (`-t` and `-T` options from the command line, `coursierDependencyTree` and `coursierDependencyInverseTree` from the SBT plugin, [#243])
* Add support for HTTP authentication (specify like `-r http://user:pass@repo.com/path` from the command-line, with the special key `coursierCredentials` from the SBT plugin - support for SBT `credentials` key to come soon - [#243])
* Experimental: add early support for using an SBT project as a repository for its projects (really experimental / probably unstable, [#243])
* Handle Maven properties names with a wider range of characters ([#247])

### Non-backward compatible changes

* Possible minor incompatible binary changes because of the added support for authentication, it is recommended to recompile your code against the `1.0.0-M12` version.
