# Changelog: 2025-02-04

## Highlights

* **Enabled support for FlashAttention**: Training Jobs can now make use of the FlashAttention package without requiring any additional setup other than including it in the `requirements.txt` file of the repository.

## Added

* **Checkpoint Details**: Use the `flexai checkpoint inspect` command to view the detailed contents and metadata of checkpoints uploaded via the `flexai checkpoint push`, including its files, source, and both creation and update times.
* **Storage Connection Details:** Use the `storage inspect` command to review connections to storage providers (e.g. AWS S3) and associated metadata.
* **Enabled support for FlashAttention**: The Training runtime now includes the `FLASH_ATTENTION_SKIP_CUDA_BUILD=1` environment variable to allow for the [flash-attn](https://github.com/Dao-AILab/flash-attention) to be used during Training Jobs.

## Changed

* **Validation for Storage Connections**: When creating a Remote Storage Provider Connection using `flexai storage create`, an error will be returned if the specified Secret name cannot be found, providing immediate feedback instead of creating an invalid connection.
* **Enhanced Training commands messages**: Improved the messages for `flexai training` subcommands to provide more context and better guidance during the different workflows.

## Fixed

* **Last Checkpoint Availability:** Fixed an issue where the final checkpoint created by FCS-managed checkpoints for a Training Job was sometimes inaccessible.
