# Nushell 0.27
Nushell, or Nu for short, is a new shell that takes a modern, structured approach to your commandline. It works seamlessly with the data from your filesystem, operating system, and a growing number of file formats to make it easy to build powerful commandline pipelines.
Today, we're releasing 0.27 of Nu. This release fixes some long-standing issues with Nushell.
