Use this tab when a class, tutorial, or older blog post assumes a different NumPy version than the one you have. The Release notes page is the official changelog—skim it to see what changed (new features, deprecations, compatibility notes) and which Python versions are supported for each NumPy release. This is the fastest way to confirm “what’s different in 2.3 vs 2.2” before you troubleshoot code.
If older code stops working—especially code written for NumPy 1.x—open the NumPy 2.0 migration guide. NumPy 2.0 made a one-time cleanup: some long-deprecated names were removed, type-promotion rules were standardized, and projects that use the C API may need a rebuild. The migration guide lists the specific changes and how to update your code (or what to replace). For context, the 2.0 release notes and accompanying write-ups explain the rationale and tools to help with the transition.
