## [2.0.0] - 2023-03-15

### Added

- Added `Fabric.all_reduce` ([#16459](https://github.com/Lightning-AI/lightning/pull/16459))


- Added support for saving and loading DeepSpeed checkpoints through `Fabric.save/load()` ([#16452](https://github.com/Lightning-AI/lightning/pull/16452))


- Added support for automatically calling `set_epoch` on the `dataloader.batch_sampler.sampler` ([#16841](https://github.com/Lightning-AI/lightning/pull/16841))


- Added support for writing logs to remote file systems with the `CSVLogger` ([#16880](https://github.com/Lightning-AI/lightning/pull/16880))


- Added support for frozen dataclasses in the optimizer state ([#16656](https://github.com/Lightning-AI/lightning/pull/16656))


- Added `lightning.fabric.is_wrapped` to check whether a module, optimizer, or dataloader was already wrapped by Fabric ([#16953](https://github.com/Lightning-AI/lightning/pull/16953))


### Changed

- Fabric now chooses `accelerator="auto", strategy="auto", devices="auto"` as defaults ([#16842](https://github.com/Lightning-AI/lightning/pull/16842))


- Checkpoint saving and loading redesign ([#16434](https://github.com/Lightning-AI/lightning/pull/16434))
* Changed the method signatrue of `Fabric.save` and `Fabric.load`
* Changed the method signature of `Strategy.save_checkpoint` and `Fabric.load_checkpoint`
* `Fabric.save` accepts a state that can contain model and optimizer references
* `Fabric.load` can now load state in-place onto models and optimizers
* `Fabric.load` returns a dictionary of objects that weren't loaded into the state
* `Strategy.save_checkpoint` and `Fabric.load_checkpoint` are now responsible for accessing the state of the model and optimizers


- `DataParallelStrategy.get_module_state_dict()` and `DDPStrategy.get_module_state_dict()` now correctly extracts the state dict without keys prefixed with 'module' ([#16487](https://github.com/Lightning-AI/lightning/pull/16487))

- "Native" suffix removal ([#16490](https://github.com/Lightning-AI/lightning/pull/16490))
* `strategy="fsdp_full_shard_offload"` is now `strategy="fsdp_cpu_offload"`
* `lightning.fabric.plugins.precision.native_amp` is now `lightning.fabric.plugins.precision.amp`


- Enabled all shorthand strategy names that can be supported in the CLI ([#16485](https://github.com/Lightning-AI/lightning/pull/16485))

- Renamed `strategy='tpu_spawn'` to `strategy='xla'` and `strategy='tpu_spawn_debug'` to `strategy='xla_debug'` ([#16781](https://github.com/Lightning-AI/lightning/pull/16781))


- Changed arguments for precision settings (from [64|32|16|bf16] to ["64-true"|"32-true"|"16-mixed"|"bf16-mixed"]) ([#16767](https://github.com/Lightning-AI/lightning/pull/16767))

- The selection `Fabric(strategy="ddp_spawn", ...)` no longer falls back to "ddp" when a cluster environment gets detected ([#16780](https://github.com/Lightning-AI/lightning/pull/16780))

- Renamed `setup_dataloaders(replace_sampler=...)` to `setup_dataloaders(use_distributed_sampler=...)` ([#16829](https://github.com/Lightning-AI/lightning/pull/16829))

### Deprecated

-


### Removed

- Removed support for PyTorch 1.10 ([#16492](https://github.com/Lightning-AI/lightning/pull/16492))


- Removed support for Python 3.7 ([#16579](https://github.com/Lightning-AI/lightning/pull/16579))
