v0.33.0

[mqtt5 0.33.0] - 2026-06-13

Fixed

• Broker config required every field to be present - BrokerConfig derived Deserialize without a container-level #[serde(default)], so a config file passed to mqttv5 broker --config failed to parse if it omitted any non-Option, non-defaulted field (e.g. max_clients), contradicting the per-field defaults documented in CLI_USAGE.md. Added #[serde(default)] to BrokerConfig and the nested AuthConfig, RateLimitConfig, StorageConfig, and WebSocketConfig, so omitted fields (including nested sub-fields) fall back to their Default impls. A minimal {} config is now valid (issue #85).

Changed

• BREAKING: SCRAM credential functions no longer expose getrandom::Error - ScramCredentials::from_password, ScramCredentials::from_password_with_iterations, generate_scram_credential_line, and generate_scram_credential_line_with_iterations now return the crate's own Result<_, MqttError> (mapping salt-generation failure to MqttError::Io) instead of std::result::Result<_, getrandom::Error>. This removes the third-party error type from the public API so future getrandom bumps are no longer breaking. Callers matching on getrandom::Error must switch to MqttError; callers using ? or anyhow are unaffected.
• Bumped mqtt5-protocol dependency to 0.14 - pulls in the breaking hashbrown 0.17 change (see below).
• Updated dependencies - getrandom 0.3 → 0.4 (now an internal detail), sha2 0.10 → 0.11, rand 0.9 → 0.10 (the random() method moved to the new RngExt trait, updated internally), toml 0.9 → 1, tokio-tungstenite 0.28 → 0.29, and the OpenTelemetry stack (opentelemetry/opentelemetry_sdk/opentelemetry-otlp 0.31 → 0.32, tracing-opentelemetry 0.32 → 0.33). All internal; no further public-API impact.

[mqtt5-protocol 0.14.0] - 2026-06-13

Changed

• BREAKING: bumped hashbrown 0.16 → 0.17 - SubscriptionManager::all() returns hashbrown::HashMap<String, Subscription>, a public return type, so the crate-version change of HashMap is SemVer-breaking for consumers that name it.

[mqtt5-wasm 1.3.3] - 2026-06-13

Changed

• Transitive bump: mqtt5 0.33 and mqtt5-protocol 0.14 - no wasm surface changes; the breaking dependency changes are not re-exported through the wasm API. Also updates own dependencies getrandom 0.3 → 0.4, sha2 0.10 → 0.11, and gloo-timers 0.3 → 0.4.

[mqttv5-cli 0.27.4] - 2026-06-13

Changed

• Transitive bump: mqtt5 0.33 - picks up the config-file defaults fix (issue #85) end-to-end. Also updates own dependencies rand 0.9 → 0.10, toml 0.9 → 1, and getrandom 0.3 → 0.4. No CLI surface changes.
