TorchRL Files

TorchRL 0.13.2 is a patch release focused on regression fixes, release reliability, and CI stability. It intentionally avoids new feature backports.

Highlights

• Fixed Isaac Lab reset regressions, including Direct-env autoreset opt-in behavior, observation-key normalization, and reset_to edge cases.
• Fixed SliceSampler and EnvBase.step regressions affecting compile compatibility and batch-locked environments.
• Fixed MultiSyncCollector worker-output gathering and improved preemption throughput without busy-waiting.
• Made the vLLM FP32 override opt-in so importing TorchRL no longer changes host vLLM behavior.
• Restored and hardened nightly/release publishing checks, including PyPI wheel filtering and release-build symbol stripping.
