# v0.8.1 - 2026-10-23

NeMo Helix v0.8.1 is a patch release for the 0.8 release line with security updates and fixes for authentication, Fabric validation, and Studio date filters.

## What's fixed

* **OIDC token refresh.** Brokered CLI token refresh uses the bearer token returned by the server. See [OIDC Setup](/nemo-helix/v0.10/documentation/access-control/authentication/oidc-setup).
* **Workflow-only Fabric validation.** Otherwise healthy workflow-only Fabric configurations are no longer rejected for the `no resolution strategy selected` warning. Other preflight problems still block validation, and the same warning still blocks harness configurations.
* **Studio date filters.** Calendar edits remain draft until **Apply**. Cancelling or dismissing the picker restores the committed range when it is reopened, and applied ranges use UTC day boundaries. Opening the picker no longer changes trace filters or triggers a refetch before **Apply**.
* **Certificate trust and dependency security.** Container builds update system and Python certificate trust stores and embedded TLS clients. LiteLLM is pinned to `1.95.1` for security fixes while preserving the 0.8 release line's garak version.
* **RL image hardening.** RL image builds exclude unused Mooncake transfer-engine wheels and clean up wheel-cache references across uv cache versions.

## Upgrade from v0.8.0

When using uv to install or update NeMo Helix, use **uv 0.13.4 or later**. Source-checkout users should refresh their toolchain with Flox, or install the versions reported by `make toolchain-versions` when using the system-toolchain path. See [Setup](/nemo-helix/v0.10/documentation/get-started/setup).

## Known issues

* The sandboxing in GRPO fine-tuning has not undergone security review.
