== Language ==

 * Mixins
   * Mixins can now declare protected and private members.
   * Mixins can now be used as proper types, such as the type of a parameter.
   * Fixed: Cannot declare a mix-in inside a namespace.
   * Fixed: Mixins cannot use the `from` declaration form of properties.
 * The `power-to` operator as in `base ** exponent` is now supported.
   * All numeric types work.
   * Augmented assignment (`**=`) works.
   * For `b ** e` where both are ints, a negative int value for `e` will throw an InvalidOperationException. You can address this by casting either to a fractional type (`number`, `decimal`, `float`).
 * Division
   * Added `//=` for augmented assignment of integers with "integer division". This corresponds to the binary arithmetic operator `//`.
   * Added error check for using "augmented fractional division" to ''modify'' integers:
     * Cannot use fractional division (/=) to modify an integer. Use integer division (//=) instead.
   * Fixed: The operator `//=` for fractional types does not floor the result like `//` does, making the two operators inconsistent.
 * Added support for `int` literals outside a 32-bit range.
   * Inferred types are now int, uint, int64 and uint32.
   * Works for decimal and hexadecimal bases.
 * Added new error check: Cannot raise events for other objects.
 * Don't run the tests of referenced libraries by default.
 * Fixed: Test blocks in generic classes ignored.

== Library ==

 * In CobraCore, added `.isRunningOnWindows` and `.isRunningOnMac`.
 * In CobraCore, changed `.isRunningOnMono` and `.isRunningOnUnix` from properties to methods.
 * Moved `IList<of>.numbered` up to `IEnumerable<of>`.
 * Added `.first`, `.take` and `.skip` extension methods to `IEnumerable<of T>`.
 * Added the overload `IEnumerable<of>.numbered(start as int)`.

== Command Line ==

 * Enhanced `-native-compiler` to search the system `PATH` if the specified compiler could not be found by the Process class.
 * In `cobra -about`, print a warning if `Cobra.Core.dll` is not found next to `cobra.exe`.
 * Fixed: `cobra -embed-run-time` requires write perms to the install directory.
The -embed-run-time/-ert option now makes a local copy of Cobra.Core which is removed later.

== Installer ==

 * Support .NET 4.5 (actually released in Cobra 0.9.1)
 * Make the Windows-based install-from-workspace.bat robust against the user's starting directory.
 * Use the environment variables "PROGRAMFILES" and "ProgramW6432" instead of hard coding "\Program Files [(x86)]".

== Other ==

 * Advanced the JVM back-end (could still use open source volunteers).
 * Better reporting of column number in error messages.
 * Updated Notepad.cobra sample to .NET 4.0.
 * Added dump-assembly.cobra command line util in Supplements/.
 * Improvements to the online wiki.
 * There have been concurrent improvements to the MonoDevelop add-in for Cobra, by Ramon Rocha.
