+# New minor release
+
+After releasing, let's say, 5.1.0, the following actions should be performed to prepare for the next release:
+
+1. Checkout 5.1.0 tag
+1. Build the code
+1. Rename `apps/emqx/test/emqx_static_checks_data/master.bpapi` to `apps/emqx/test/emqx_static_checks_data/5.1.bpapi`
+1. Add `apps/emqx/test/emqx_static_checks_data/5.1.bpapi` to the repo
+1. Delete the previous file (e.g. `5.0.bpapi`), unless there is plan to support rolling upgrade from 5.0 to 5.2
+1. Merge the commit to master branch
