+* Force removal of Pyo3 Object to avoid memory leak: https://github.com/dora-rs/dora/pull/168
+* Bump tokio from 1.21.2 to 1.23.1: https://github.com/dora-rs/dora/pull/171
+* Create a changelog file: https://github.com/dora-rs/dora/pull/174 
+
+## v0.1.2 (2022-12-15)
+
+- Fix infinite loop in the coordinator: https://github.com/dora-rs/dora/pull/155
+- Simplify the release process: https://github.com/dora-rs/dora/pull/157
+- Use generic linux distribution: https://github.com/dora-rs/dora/pull/159
+
+## v0.1.1 (2022-12-05)
+
+This release contains fixes for:
+- Python linking using pypi release but also a redesigned python thread model within the runtime to avoid deadlock of the `GIL`. This also fix an issue with `patchelf`.
+- A deployment separation for `ubuntu` as the `20.04` version of `dora` and `22.04` version of dora are non-compatible.
+- A better tagging of api for `dora` Rust API.
+
+## v0.1.0 (2022-11-15)
+
+This is our first release of `dora-rs`!
+
+The current release includes:
+- `dora-cli` which enables creating, starting and stopping dataflow.
+- `dora-coordinator` which is our control plane.
+- `dora-runtime` which is manage the runtime of operators.
+- `custom-nodes` API which enables bridges from different languages.
