• update_batch_size in where(): Enhanced where() operation now supports update_batch_size parameter (#1365) (847a86c4)
• tolist_first(): New method for converting TensorDict to list with first-level flattening (#1334) (73fe89bc)

Torch Function Integration

• torch.maximum support: Added support for torch.maximum operation in TensorDict (#1362) (85f26e41)

CUDA Graph Enhancements

• CudaGraphModule.state_dict(): New method to access state dictionary of CUDA graph modules (#1346) (909907b1)
• Improved device handling: Better support for CUDA graph operations on non-zero devices (#1315) (89d05a1c)
• Stream management: Enhanced stream handling for CUDA graph operations (#1314) (2fd4843c)

Non-Tensor Data Support

• NonTensorDataBase and MetaData: New base classes for handling non-tensor data in TensorDict (#1324) (8d0241d4)
• Enhanced metadata handling: Improved support for metadata operations

Copy Operations

• TensorDict.__copy__(): New method for creating shallow copies of TensorDict instances (#1321) (b6feadd1)

Distributed tensordicts

• broadcast tensordicts: New functionality for broadcasting TensorDict instances across different shapes (#1307) (29598633)
• remote_init with subclasses: Enhanced remote initialization support for TensorDict subclasses (#1308) (5859a2cf)
