+# Deprecating and Removing Code
+
+libcudf is constantly evolving to improve performance and better meet our users' needs. As a
+result, we occasionally need to break or entirely remove APIs to respond to new and improved
+understanding of the functionality we provide. Remaining free to do this is essential to making
+libcudf an agile library that can rapidly accommodate our users needs. As a result, we do not
+always provide a warning or any lead time prior to releasing breaking changes. On a best effort
+basis, the libcudf team will notify users of changes that we expect to have significant or
+widespread effects.
+
+Where possible, indicate pending API removals using the
+[deprecated](https://en.cppreference.com/w/cpp/language/attributes/deprecated) attribute and
+document them using Doxygen's
+[deprecated](https://www.doxygen.nl/manual/commands.html#cmddeprecated) command prior to removal.
+When a replacement API is available for a deprecated API, mention the replacement in both the
+deprecation message and the deprecation documentation. Pull requests that introduce deprecations
+should be labeled "deprecation" to facilitate discovery and removal in the subsequent release.
+
+Advertise breaking changes by labeling any pull request that breaks or removes an existing API with
+the "breaking" tag. This ensures that the "Breaking" section of the release notes includes a
+description of what has broken from the past release. Label pull requests that contain deprecations
+with the "non-breaking" tag.
