This release introduces new features including GIF animation support, wandb run resumption, and improved ensemble loading, alongside a large number of bug fixes and maintenance updates.

- Enable `pin_memory` in DataLoaders when GPU is available for faster async CPU-to-GPU data transfers [\#236](https://github.com/mllam/neural-lam/pull/236) @abhaygoudannavar

- Expose `--wandb_id` CLI argument to allow resuming an existing W&B run by
ID. When provided, `resume="allow"` is set automatically so the same job
script works for both the initial submission and all resubmissions, making
it suitable for HPC systems with limited job runtimes or that may crash.
[\#197](https://github.com/mllam/neural-lam/pull/197) @Mani212005

### Changed

- Change the default ensemble-loading behavior in `WeatherDataset` / `WeatherDataModule` to use all ensemble members as independent samples for ensemble datastores (with matching ensemble-member selection for forcing when available); single-member behavior now requires explicitly opting in via `--load_single_member` [\#332](https://github.com/mllam/neural-lam/pull/332) @kshirajahere

- Refactor graph loading: move zero-indexing out of the model and update plotting to prepare using the research-branch graph I/O [\#184](https://github.com/mllam/neural-lam/pull/184) @zweihuehner
- Replace `print()`-based `rank_zero_print` with `loguru` `logger.info()` for structured log-level control ([#33](https://github.com/mllam/neural-lam/issues/33))

- Switch to lat/lon-based plotting with `pcolormesh` and `cartopy` for accurate spatial visualisation regardless of underlying projection. [\#168](https://github.com/mllam/neural-lam/pull/168) @sadamov

- Infer spatial coordinate names for MDPDatastore (rather than assuming names `x` and `y`), allows for e.g. lat/lon regular grids [\#169](https://github.com/mllam/neural-lam/pull/169) @leifdenby
