+# As of v3.1.0, attr_encrypted is not thread-safe because all instances share the same `encrypted_attributes`
+# This was fixed in https://github.com/attr-encrypted/attr_encrypted/commit/d4ca0e2073ca6ba5035997ce25f7fc0b4bfbe39e
+# but no release was made after that so we have to patch it ourselves here
