Developer’s Guide#

This discusses information relevant to developing MetPy.


MetPy follows semantic versioning in its version number. This means that any MetPy 1.x release will be backwards compatible with an earlier 1.y release. By “backward compatible”, we mean that correct code that works on a 1.y version will work on a future 1.x version. It’s always possible for bug fixes to change behavior or make incorrect code cease to work. Backwards-incompatible changes will only be allowed when changing to version 2.0. Such changes will be proceeded by MetpyDeprecationWarning or FutureWarning as appropriate. For a version 1.x.y, we change x when we release new features, and y when we make a release with only bug fixes.
