= Cobra 0.9.0 Release Notes =

Since the last release there are almost too many improvements to list. You can browse [http://cobra-language.com/trac/cobra/log/ the revision log] online if you care too.

Some highlights just from the last few months include:

== Language ==

 * Improvements to the @help directive.
 * Throw an UnpackException for multi-target assignment (target1, target2 = source) if there is a mismatch in the number of source items and targets
 * Support unpacking the new Pair classes in assignments and for loops.
 * Enhance the treatment of == and <> between objects to fall back to a strongly type .equals method if a strongly typed .compareTo method is not available.
 * Improved error checking and improved error messages.
 * Bug fixes.

== Library ==

 * Renamed "Cobra.Lang" to "Cobra.Core"
 * New MultiList class.
 * New Pair<of TA, TB> and Pair<of T> clasess.
 * Improve the default formatting of the `trace` statement (which is also configurable).
 * Added `Stack.clone` extension method that preserves the ordering of the stack elements.
 * A Cobra.Compiler library is now always provided during installation.
 * Bug fixes.

== Command Line ==

 * Command line: -native-compiler: The absolute path to the native compiler is no longer required. A simple "csc.exe" or "dmcs" will suffice if it is in the system PATH.
 * Added -clr-platform option (like C#'s -platform option).

== Learning ==

 * Added new How To: Customize Object Equality.
 * Kickstarted [wiki:Koans Cobra Koans].
