+
+## [Unreleased]
+
+## [0.1.0]
+
+### Added
+
+- **Deep memory profiling** with memray driven as a library: per-source-line
+  high-water-mark attribution and full call stacks for a per-worker flamegraph /
+  memray-style tree. Opt-in `deep=True`; degrades to lightweight sampling where
+  memray isn't available.
+- **Real-time dashboard** (Next.js) streaming over WebSocket: live Workers table,
+  global + per-worker task stream, whole-graph canvas DAG, memory-over-time with
+  a click-to-inspect spike explorer, per-layer allocations over time, and the
+  deep flamegraph. Collapsible sidebar, in-app modals, Dask warm palette + logo.
+- **TimescaleDB** backend (hypertables) as the default collector store behind a
+  `StoreProtocol`, with SQLite kept for local use and tests. Prometheus
+  `/metrics` retained.
+- **Worker-death post-mortem** joining suspect tasks with chunk metadata and the
+  allocation lines at the high-water mark.
+- **Origin tracking** — each run records the client hostname and IP.
+- **Examples** across Dask: distributed/deep OOM demos, a minutes-long pipeline,
+  a self-limiting crash, and one per collection type (`dask.delayed`,
+  `dask.dataframe`, `dask.bag`, xarray on Zarr and NetCDF).
+- Packaging (PyPI metadata, MIT license), CI, and release workflows.
