CHANGELOG.md

@@ -24,6 +24,7 @@ Docs: https://docs.openclaw.ai
 - Providers/OpenRouter: remove conflicting top-level `reasoning_effort` when injecting nested `reasoning.effort`, preventing OpenRouter 400 payload-validation failures for reasoning models. (#24120) thanks @tenequm.
 - Skills/Python: add CI + pre-commit linting (`ruff`) and pytest discovery coverage for Python scripts/tests under `skills/`, including package test execution from repo root. Thanks @vincentkoc.
 - Telegram/Polling: scope persisted polling offsets to bot identity and reuse a single awaited runner-stop path on abort/retry, preventing cross-token offset bleed and overlapping pollers during restart/error recovery. (#10850, #11347) Thanks @talhaorak, @anooprdawar, and @vincentkoc.
+- Telegram/Reactions: soft-fail reaction action errors (policy/token/emoji/API), accept snake_case `message_id`, and fallback to inbound message-id context when explicit `messageId` is omitted so DM reactions stay stable without regeneration loops. (#20236, #21001) Thanks @PeterShanxin and @vincentkoc.
 - Sessions/Store: canonicalize inbound mixed-case session keys for metadata and route updates, and migrate legacy case-variant entries to a single lowercase key to prevent duplicate sessions and missing TUI/WebUI history. (#9561) Thanks @hillghost86.
 - Security/CI: add pre-commit security hook coverage for private-key detection and production dependency auditing, and enforce those checks in CI alongside baseline secret scanning. Thanks @vincentkoc.
 - Skills/Python: harden skill script packaging and validation edge cases (self-including `.skill` outputs, CRLF frontmatter parsing, strict `--days` validation, and safer image file loading), with expanded Python regression coverage. Thanks @vincentkoc.
