# DSM Accelerator [4.31] - Aug 06, 2024

## 1. Overview

This article provides an overview of general improvements and resolved issues in the Fortanix Data Security Manager (DSM) Accelerator 4.31 release.

## 2. Improvements and Bug Fixes

- **DSM Accelerator JCE Provider:**
  - A new variant of the DSM Accelerator JCE Provider Thin client is now created as a single unified JAR that contains the Fortanix dependencies (`sdkms-client` and `dsm-accelerator`) (**JIRA: PROD-8857**).

*For more details, refer to the following documents:*
    - [*DSM Accelerator JCE Provider Deployment Guide*](/v1/docs/dsm-accelerator-jce-provider-deployment-guide)
    - [*DSM Accelerator JCE Provider Downloads*](/v1/docs/dsm-accelerator-downloads-dsm-accelerator-jce-provider)
  - Improved the key retrieval process in the DSM Accelerator JCE Provider to utilize the cached data more efficiently (**JIRA: PROD-8799**).
  - Fixed the `NoPadding` scheme for the DSM Accelerator JCE Provider where the ciphertext length correctly matches the input length (**JIRA: ES-385**).
