+
+## [0.8.6] - 2020-01-22
+
+### Added
+
+- Windows build now supported.
+- Added metrics to retrieve stats such as `procs_running` and `procs_blocked`.
+- Added metrics to retrieve network stats.

+  and kernel integrity.
+
+### Changed
+
+- Print result's message when status is unknown.
+
+### Fixed
+
+- Fixed custom plugin command timeout when the command spawns a long running
+  child process.
+
+## [0.8.5] - 2020-11-18
+
+### Added
+
+- Added problem detection for buffer I/O error.
+- Added CPU load average metrics support.
+- Added kubelet apiserver connection check in health checker.
+
+### Changed
+
+- Will now catch hung task with pattern like `tasks airflow scheduler: *`.
+- Better handling to avoid duplicating disk bytes metrics used on fstype and
+  mount types.
+
+### Fixed
+
+- Fixed the deployment yaml to prevent NPD from scheduling onto windows nodes.
+- Fixed memory unit for `/proc/meminfo` metrics.
+- Fixed OOMKilling detection for new linux kernel v5.1+.
+
+## [0.8.4] - 2020-09-01
+
+### Added
+
+- Added `FSType` and `MountOption` as labels to the metric `disk_usage_bytes`.
+- Added `DockerContainerStartupFailure` event in `docker-monitor.json` to
+  detect docker issue
+  [docker/for-linux#647](https://github.com/docker/for-linux/issues/647).
+
+### Fixed
+
+- Reduced log spam generated by the custom plugin monitor.
+
+## [0.8.3] - 2020-06-30
+
+### Added
+
+- `health-checker` binary now included in the docker image.
+
+### Changed
+
+- `--enable-repair=true` is now the default for docker and kubelet health
+  checker.

+  and discarded.
+
+### Fixed
+

+
+### Added
+
+- Added an `--event-namespace` flag to make event namespace configurable.

+  `enable-repair` is turned on.

+
+### Added
+
+- Added a system stats monitor is added into NPD as a new problem daemon. It
+  collects useful node problem related system stats with OpenCensus such as
+  `disk/io_time`, `disk/weighted_io` and `disk/avg_queue_len`.
+- Besides node condition and events, problems detected by existing problem
+  daemons are also collected into OpenCensus as metrics:
+  `problem_counter{reason="PROBLEM_REASON"} xxx` for events and
+  `problem_gauge{reason="PROBLEM_REASON",type="PROBLEM_TYPE"} 1 or 0` for
+  conditions.
+- A Prometheus exporter is added to export all OpenCensus metrics collected by
+  NPD through Prometheus.
+- A plugin system for problem daemons is added. Problem daemons can be disabled
+  at compile time with build tags, such as `disable_system_stats_monitor`,

+- A problem exporter interface is added. The original kubernetes problem
+  reporting logic was moved into `k8sexporter`. Prometheus support is
+  implemented as `prometheusexporter`.
