+## Breaking Changes
+
+Most changes included in the nanoarrow 0.6.0 release will not break downstream
+code; however, several changes in the C library are breaking changes to previous
+behaviour.

+
+## Features
+

+Lastly, the CMake build system was refactored to enable `FetchContent` to
+work in an even wider variety of
+[develop/build/install scenarios](https://github.com/apache/arrow-nanoarrow/tree/main/examples/cmake-scenarios). In most cases, CMake-based projects should be able
+to add the nanoarrow C library with device and/or IPC support as a dependency with:
+
+```cmake
+include(FetchContent)
+
+set(NANOARROW_IPC ON)
+set(NANOARROW_DEVICE ON)
+fetchcontent_declare(nanoarrow
+                     GIT_REPOSITORY https://github.com/apache/arrow-nanoarrow.git
+                     GIT_TAG  apache-arrow-nanoarrow-0.6.0
+                     GIT_SHALLOW TRUE)
+fetchcontent_makeavailable(nanoarrow)
+
+add_executable(some_target ...)
+target_link_libraries(some_target PRIVATE nanoarrow::nanoarrow_ipc nanoarrow::nanoarrow_device)
+```
+
+- Works in Meson, too
