On behalf of the IronPython team, I'm very happy to announce the
release of IronPython 2.7.5[1]. Like all IronPython 2.7-series
releases, .NET 4 is required to install it. Installing this release
will replace any existing IronPython 2.7-series installation.
Assemblies for embedding are provided for .NET 3.5, .NET 4, .NET 4.5,
and Silverlight 5.

IronPython 2.7.5 is primarily a collection of bug fixes[2] which
smooths off many of the remaining rough edges. The complete list of
changes[3] is also available.

A major new feature is the inclusion of `ensurepip`, which will
install the `pip` package manager:

```
; -X:Frames is required when using pip
ipy.exe -X:Frames -m ensurepip

; Run from an Administrator console if using IronPython installer
ipy.exe -X:Frames -m pip install html5lib
```

**Note:** The assembly version of IronPython has changed to 2.7.5.0.
All previous 2.7 versions had the same version (2.7.0.40) which caused
issues when different versions were installed. Publisher policy files
are used to so that applications don't have to be recompiled, but
recompiling is strongly recommended.

A huge thanks goes out to Pawel Jasinski, who contributed most of the
changes in this release. Thanks is also due to Simon Opelt, Alex Earl,
Jeffrey Bester, yngipy hernan, Alexander Köplinger,Vincent Ducros, and
fdanny.

For Visual Studio integration, check out Python Tools for Visual
Studio[4] which has support for IronPython as well as CPython, and
many other fantastic features.

IronPython 2.7.5 is also available for embedding via NuGet. The main
package is IronPython, and the standard library is in
IronPython.StdLib.

- Jeff
