+## Changes in 1.5.3
+
+### Bug fixes
+
+- **Doubleranged filter fixes**: Range filters now correctly handle zero as a
+  boundary value. Improved validation and UI text for "more than equal" and
+  "less than equal" range selections.
+- **Lineprotocol body parsing interrupted**: Switched from `ReadTimeout` to
+  `ReadHeaderTimeout` so that long-running metric submissions are no longer
+  cut off mid-stream.
+- **Checkpoint archiving continues on error**: A single cluster's archiving
+  failure no longer aborts the entire cleanup operation. Errors are collected
+  and reported per cluster.
+- **Parquet row group overflow**: Added periodic flush during checkpoint
+  archiving to prevent exceeding the parquet-go 32k column-write limit.
+- **Removed metrics excluded from subcluster config**: Metrics removed from a
+  subcluster are no longer returned by `GetMetricConfigSubCluster`.
+
+### MetricStore performance
+
+- **WAL writer throughput**: Decoupled WAL file flushing from message processing
+  using a periodic 5-second batch flush (up to 4096 messages per cycle),
+  significantly increasing metric ingestion throughput.
+- **Improved shutdown time**: HTTP shutdown timeout reduced; metricstore and
+  archiver now shut down concurrently. Overall shutdown deadline raised to
+  60 seconds.
+
+### New features
+
+- **Manual checkpoint cleanup flag**: New `-cleanup-checkpoints` CLI flag
+  triggers checkpoint cleanup without starting the server, useful for
+  maintenance windows or automated cleanup scripts.
+- **Explicit node state queries in node view**: Node health and scheduler state
+  are now fetched independently from metric data for fresher status information.
+
+### Logging improvements
+
+- **Reduced tagger log noise**: Missing metrics and expression evaluation errors
+  in the job classification tagger are now logged at debug level instead of
+  error level.
