Nikola v7.8.15 and v8.0.0b1 are out!

On behalf of the Nikola team, I am pleased to announce the immediate availability of Nikola v7.8.15 and v8.0.0b1.

Nikola v7.8.15 is the last v7 maintenance release with a few more bug fixes.

Nikola v8.0.0b1 (Beta 1) is the first test release of the v8 series. The v8 series adds a ton of new features and fixes bugs, while also breaking backwards compatibility.

What is Nikola?

Nikola is a static site and blog generator, written in Python. It can use Mako and Jinja2 templates, and input in many popular markup formats, such as reStructuredText and Markdown — and can even turn Jupyter (IPython) Notebooks into blog posts! It also supports image galleries, and is multilingual. Nikola is flexible, and page builds are extremely fast, courtesy of doit (which is rebuilding only what has been changed).

Find out more at the website:


Install using pip install Nikola==7.8.15 or pip install Nikola==8.0.0.beta1.

Before upgrading to Nikola v8, make sure to read the “Upgrading” document.
