+## 0.4.0 - 2026-07-11
+
+### Added
+
+- Support dynamic channel credentials by allowing fields such as `token`, `topic`,
+  and `user` to be zero-argument callables resolved when a request is built.
+- Add CI coverage enforcement with a 95% minimum total coverage threshold.
+- Add explicit channel registry lookup for `Notify.from_settings`.
+
+### Fixed
+
+- Avoid rendering `None` in title-less Chanify and WeChat messages.
+- Align Email async missing-recipient logging with the documented `to_emails`
+  field.
+- Avoid over-redacting ordinary single-segment URLs while still redacting
+  secret-like provider paths.
+- Reject bool values for numeric retry and Email port configuration.
+
+### Tests
+
+- Expand channel, retry, Email, provider response, redaction, and dynamic
+  credential coverage. The suite now runs 126 tests with 97% total coverage.
