The combined work of Gina and four awesome contributors to get done and shipped. This happened with the release of OctoPrint 1.4.0 and took well over a year and

Going Python 3 exclusive was not an option. However, as all OctoPi images up to and including 0.17 also shipped with a Python 2 environment for OctoPrint, Order to be future-proof (and also to profit of the new possibilities and performance gains that Python 3 offers).

This meant that OctoPrint, only compatible to Python 2 up until version 1.4.0, had to become Python 3 compatible in Python 2 has been officially declared end-of-life (EOL) by the Python maintainersĪs of January 1st of 2020, meaning it will no longer get any more updates (but obviously still continue to work as-is!). Two versions of Python – Python 2 and 3 – with some big changes and incompatibilities between them. Up until the start of the year, there were Python is the programming language that OctoPrint is primarily written in. Wait a second! Python 2 EOL? Python 3? What does all of this even mean? It’s now time to migrate more installs to Python 3. OctoPrint, to each and every plugin developer who heard the call to update their plugins to be both

Things have changed though! As I’m writing this now, 67% of plugins are compatible with Python 3! There needs toīe a massive shoutout to everyone who worked to make this possible, from those who contributed to core

Thus so far Python 3 The main reason for this is that all current OctoPi releases up until now shipped with OctoPrint installed under Python 2.īut there was also the issue of compatibility of the plugins in the plugin repository. However, at the time of writing, only 2.3% of all tracked installs are running on Python 3. Since OctoPrint version 1.4.0, the codebase has supported installation on both Python 2 and Python 3Įnvironments, as a result of Python 2’s EOL status.
