Repo2RLEnv graduated from text-only diffs to fully containerized, verifiable RL tasks with a 6-component reward function and 100 production-ready environments on the Hub.
The pr_diff module [1] is now a complete RL environment: every task emits a Dockerfile and test suite that Harbor can execute, with deterministic reward verification across five components plus LLM-as-judge grading. This closes the gap between diff generation and actual execution feedback. The reference dataset [1] lands on HF Hub with 100 verified environments, giving teams immediate ground truth for training and evaluation.
In parallel, transformers [2] landed FSDP initialization through from_pretrained, eliminating custom boilerplate for distributed training setup. The ALM encoder [6] dropped its head-only design, adding a base model class and backward-compatible conversion mappings across the suite. GLM-4.6V [7] got its VideoProcessor update for multimodal support, and a T5Gemma regression [5] in encoder-decoder generation is fixed: cross-attention cache was incorrectly inheriting decoder sliding-window config and truncating encoder states under FlashAttention.
Lerobot patched policy.path in YAML configs [3], which shipped broken in PR #3145 for the canonical use case (omitting type discriminator). The fix removes the field before deserialization and applies sibling overrides downstream. GR00T's vendored Eagle25VL [8] now declares unified Flash Attention support for Transformers 5.4+, eliminating crashes on newer runtimes.
Kernels [4] added stable-abi support to build.toml, letting you target specific Torch ABI versions without rebuilding binaries. Repo2RLEnv also hardened itself against instruction info-leak: PR descriptions with issue links no longer leak the answer frontier models are supposed to find [1]. Dependabot weekly bumps land for GitHub Actions [9], with a 7-day cooldown to align with org security gates.
