-## [Unreleased]
+## [0.4.1] - 2026-07-19
+
+### Added
+- Added an experimental fuzzing harness that runs plugins for an extended period of time to discover potential issues.
+- Add parameter rescan checks to `state-reproducibility-*` tests.
+- Add `render` extension support, call `render::set` while fuzzing.
+- Add overlapping & wildcard event checks.
+- Add out-of-bounds write checks for output/inplace buffers.
 
 ### Changed
+- Bump MSRV to 1.95.0.
+- Remove `features-standard` test (too strict).
+
+### Fixed
+- Allow calling host methods inside `clap_plugin::init`.
+- Fix `clap_plugin::activate` cycle detection logic (thanks @edwloef!)
+
+## [0.4.0] - 2026-03-28
+
+### Added
 
+- New tests: 
+  - `features-standard`
+  - `layout-audio-ports-activation`
+  - `layout-audio-ports-config`
+  - `layout-configurable-audio-ports`
+  - `process-audio-basic-in-place`
+  - `process-audio-double-in-place`
+  - `process-audio-double-out-of-place`
+  - `process-audio-denormals`
+  - `process-sleep-constant-mask`
+  - `process-sleep-process-status`
+  - `process-varying-block-sizes`
+  - `process-varying-sample-rates`
+  - `process-random-block-sizes`
+  - `process-reset-reactivate`
+  - `param-fuzz-bounds`
+  - `param-fuzz-sample-accurate`
+  - `param-fuzz-modulation`
+  - `param-set-events`
+  - `param-set-no-cookies`
+  - `param-default-values`
+  - `state-invalid-random`
+  - `state-reproducibility-binary` (other reproducibility tests have been relaxed to not check for exact binary state matches)
+  - `transport-null`
+  - `transport-fuzz`
+  - `transport-fuzz-sample-accurate`
+
+- Extra checks:
+  - `ambisonic`/`surround` checks when querying audio port info.
+  - Thread/state/extension checks for host callback functions.
+  - More lenient param reproducibility checks that allow for some imprecision when comparing parameter values.
+  - Object validity checks, now passing an invalid object pointer to a callback will catch it and report it as an error instead of causing undefined behavior in the validator. This has some performance impact but it is negligible. 
+  - Implemented more host-side extensions and specific checks for each host-side extension callback.
+  - Implemented infinite restart loop check in activate (similar to the infinite `request_callback` loop check for `on_main_thread`).
+  - Check if `clap_audio_buffer` data is not modified by the plugin within the `clap_plugin::process` call. 
+
+### Changed
+
+- Update `clap-sys` to latest (CLAP 1.2.2)
 - Having both the `CLAP_PARAM_IS_READONLY` flag and any of the
   `CLAP_PARAM_IS_AUTOMATABLE` or `CLAP_PARAM_IS_MODULATABLE` flags set now
   results in an error.
 - The logic for which parameters can be randomized has changed. Previously all
   parameters marked as automatable could be changed. Now parameters marked as
   hidden or readonly are ignored instead, as non-automatable parameters can
   still be changed as the result of live user input.
+- When doing out-of-process validation, the validator now also checks for timeouts in addition to crashes. 
+If a plugin takes too long to respond during validation, the validator will kill the process and report a timeout error. The timeout duration is currently set to 45 seconds.
+- Pretty printing of validation/list/scan results in non-JSON output modes has been improved.
+- Changed log formatting to be prettier, plugin log messages are propagated to the validator's output via the `log` extension.
+- Added `clap-validator.toml` config files for easier per-project test enabling/disabling.
+- When running validation in-process, it is possible to turn on tracing, which emits a detailed Chrome-tracing compatible .json trace file that can be loaded into Chrome's tracing viewer or other compatible tools. This is especially useful for debugging test failures and crashes.
+
+- Removed tests:
+  - `state-reproducibility-flush` - replaced by `param-set-events`.
+  - `state-reproducibility-null-cookies` - replaced by `param-set-no-cookies`.
+
+### Fixed
+  - Wrong state transition check on plugin instance destroy.
+  - Output note events were queried as inputs.
