+### Security
+
+- Roll back `serde_derive` to version 1.0.171 and pin it there, to avoid using [the new `serde_derive` that uses a pre-built binary compiler plugin](https://github.com/serde-rs/serde/issues/2538). The binary plugin has not been successfully reproduced from source when I last looked, and it represents an unacceptable security risk, since it can't be audited without disassembling the binary code. We'll need a longer-term plan for this.
