We are excited to announce the 2025.12 release of the Anaconda Distribution installer, which includes:

  • Python – the most widely used programming language for AI, data science and machine learning
  • conda – the open-source, cross-platform package and environment manager
  • Anaconda Navigator – our desktop application, built on conda, that enables you to launch notebooks and development applications from your managed environments
  • And over 300 additional, automatically-installed packages that have been tested together to work “out of the box”

Anaconda Distribution is free to download, easy to install, and has an active community forum where users help each other troubleshoot issues. The installer is pre-configured to access Anaconda’s public package repositories that include thousands of AI, data science, and machine learning packages across four different platforms.
