Verifiers v0.1.13.dev7 Release Notes

Date: 04/24/2026

Highlights since v0.1.13.dev6

• rlm_harness swaps turn-based context caps for token-based auto-compaction: new summarize_at_tokens: int | None kwarg maps to RLM_SUMMARIZE_AT_TOKENS, while rlm_max_turns_in_context / RLM_MAX_TURNS_IN_CONTEXT are removed to match upstream rlm. summarize also drops out of the default rlm_tools set. Invalid shapes fail at harness-build time instead of deep inside the sandbox.
• Reverted TaskSet.filter / .take returning Self (originally #1232) — the change broke Python 3.10/3.11 compatibility. CI now exercises the 3.10 and 3.11 test matrices so the fix can be restored with confidence.
