+
+### Breaking changes
+
+The CLI version of `cihai` installed through `cihai-cli` again
+
+Before (cihai 0.9 to 0.14, cihai-cli 0.5 to 0.10):
+
+```console
+$ pip install cihai[cli]
+```
+
+After (cihai 0.15+, cihai-cli 0.11+):
+
+```console
+$ pip install cihai-cli
+```
+
+This made deploying cihai + cihai-cli and pinning packages extremely laborious.
+
+We can reinvestigate this model in the future.
