+## [unreleased](https://github.com/joeloskarsson/neural-lam/compare/v0.1.0...HEAD)
+
+### Added
+
+- Replaced `constants.py` with `data_config.yaml` for data configuration management
+  [\#31](https://github.com/joeloskarsson/neural-lam/pull/31)
+  @sadamov
+
+- new metrics (`nll` and `crps_gauss`) and `metrics` submodule, stddiv output option
+  [c14b6b4](https://github.com/joeloskarsson/neural-lam/commit/c14b6b4323e6b56f1f18632b6ca8b0d65c3ce36a)
+  @joeloskarsson
+
+- ability to "watch" metrics and log
+  [c14b6b4](https://github.com/joeloskarsson/neural-lam/commit/c14b6b4323e6b56f1f18632b6ca8b0d65c3ce36a)
+  @joeloskarsson
+
+- pre-commit setup for linting and formatting
+  [\#6](https://github.com/joeloskarsson/neural-lam/pull/6), [\#8](https://github.com/joeloskarsson/neural-lam/pull/8)
+  @sadamov, @joeloskarsson
+
+### Changed
+
+- Updated scripts and modules to use `data_config.yaml` instead of `constants.py`
+  [\#31](https://github.com/joeloskarsson/neural-lam/pull/31)
+  @sadamov
+
+- Added new flags in `train_model.py` for configuration previously in `constants.py`
+  [\#31](https://github.com/joeloskarsson/neural-lam/pull/31)
+  @sadamov
+
+- moved batch-static features ("water cover") into forcing component return by `WeatherDataset`
+  [\#13](https://github.com/joeloskarsson/neural-lam/pull/13)
+  @joeloskarsson
+
+- change validation metric from `mae` to `rmse`
+  [c14b6b4](https://github.com/joeloskarsson/neural-lam/commit/c14b6b4323e6b56f1f18632b6ca8b0d65c3ce36a)
+  @joeloskarsson
+
+- change RMSE definition to compute sqrt after all averaging
+  [\#10](https://github.com/joeloskarsson/neural-lam/pull/10)
+  @joeloskarsson
+
+### Removed
+
+- `WeatherDataset(torch.Dataset)` no longer returns "batch-static" component of
+  training item (only `prev_state`, `target_state` and `forcing`), the batch static features are
+  instead included in forcing
+  [\#13](https://github.com/joeloskarsson/neural-lam/pull/13)
+  @joeloskarsson
+
+### Maintenance
+
+- simplify pre-commit setup by 1) reducing linting to only cover static
+  analysis excluding imports from external dependencies (this will be handled
+  in build/test cicd action introduced later), 2) pinning versions of linting
+  tools in pre-commit config (and remove from `requirements.txt`) and 3) using
+  github action to run pre-commit.
+  [\#29](https://github.com/mllam/neural-lam/pull/29)
+  @leifdenby
+
+
+## [v0.1.0](https://github.com/joeloskarsson/neural-lam/releases/tag/v0.1.0)
+
+First tagged release of `neural-lam`, matching Oskarsson et al 2023 publication
+(<https://arxiv.org/abs/2309.17370>)

 ## A note on the limited area setting
 Currently we are using these models on a limited area covering the Nordic region, the so called MEPS area (see [paper](https://arxiv.org/abs/2309.17370)).
 There are still some parts of the code that is quite specific for the MEPS area use case.
-This is in particular true for the mesh graph creation (`create_mesh.py`) and some of the constants used (`neural_lam/constants.py`).
+This is in particular true for the mesh graph creation (`create_mesh.py`) and some of the constants set in a `data_config.yaml` file (path specified in `train_model.py --data_config` ).
 If there is interest to use Neural-LAM for other areas it is not a substantial undertaking to refactor the code to be fully area-agnostic.
 We would be happy to support such enhancements.
 See the issues https://github.com/joeloskarsson/neural-lam/issues/2, https://github.com/joeloskarsson/neural-lam/issues/3 and https://github.com/joeloskarsson/neural-lam/issues/4 for some initial ideas on how this could be done.

 ### Create remaining static features
 To create the remaining static files run the scripts `create_grid_features.py` and `create_parameter_weights.py`.
-The main option to set for these is just which dataset to use.
 
 ## Weights & Biases Integration
 The project is fully integrated with [Weights & Biases](https://www.wandb.ai/) (W&B) for logging and visualization, but can just as easily be used without it.
 When W&B is used, training configuration, training/test statistics and plots are sent to the W&B servers and made available in an interactive web interface.
 If W&B is turned off, logging instead saves everything locally to a directory like `wandb/dryrun...`.
-The W&B project name is set to `neural-lam`, but this can be changed in `neural_lam/constants.py`.
+The W&B project name is set to `neural-lam`, but this can be changed in the flags of `train_model.py` (using argsparse).
