## Release 2.1.0

### Summary

This release focuses on security improvements, performance enhancements for newer GPU architectures, and extended sequence length support.

### Key Features

* **Security**: Addressed all CVE (Common Vulnerabilities and Exposures) issues
* **cuEquivariance integration**: Updated to cuEquivariance [0.7.0](https://github.com/NVIDIA/cuEquivariance/releases/tag/v0.7.0) for improved equivariant operations
* **Enhanced B200 support**: Enabled trimul kernel optimization for B200 SKUs in PyTorch backend
* **Extended sequence length**: Support for longer sequences up to 2048 residues on A100, H100, and B200 GPUs with TensorRT-BioNeMo
* **Telemetry control**: NIM Telemetry helps NVIDIA deliver a faster, more reliable experience with greater compatibility across a wide range of environments, while maintaining strict privacy protections and giving users full control.

  **Benefits:**

  * **Enhances performance and reliability**: Provides anonymous system and NIM-level insights that help NVIDIA identify bottlenecks, tune performance across hardware configurations, and improve runtime stability.
  * **Improves compatibility across deployments**: Helps detect and resolve version, driver, and environment compatibility issues early, reducing friction across diverse infrastructure setups.
  * **Accelerates troubleshooting and bug resolution**: Allows NVIDIA to diagnose errors and regressions faster, leading to quicker support response times and higher overall availability.
  * **Informs smarter optimizations and future releases**: Real-world, aggregated telemetry data helps guide the optimization of NIM runtimes, model packaging, and deployment workflows, ensuring updates target the scenarios that matter most to users.
  * **Protects user privacy and data security**: Collects only minimal, anonymous metadata, such as hardware type and NIM version. No user data, input sequences, or prediction results are collected.
  * **Fully optional and configurable**: Telemetry collection is disabled by default. You can toggle telemetry at any time using environment variables.

  **Configuration:**

  * Set `NIM_TELEMETRY_MODE=0` to disable telemetry (default)
  * Set `NIM_TELEMETRY_MODE=1` to enable telemetry
