@@ -185,6 +185,7 @@ Docs: https://docs.openclaw.ai
 - TUI/theme: detect light terminal backgrounds via `COLORFGBG` and pick a WCAG AA-compliant light palette, with `OPENCLAW_THEME=light|dark` override for terminals without auto-detection. (#38636) Thanks @ademczuk and @vincentkoc.
 - Agents/openai-codex: normalize `gpt-5.4` fallback transport back to `openai-codex-responses` on `chatgpt.com/backend-api` when config drifts to the generic OpenAI responses endpoint. (#38736) Thanks @0xsline.
 - Models/openai-codex GPT-5.4 forward-compat: use the GPT-5.4 1,050,000-token context window and 128,000 max tokens for `openai-codex/gpt-5.4` instead of inheriting stale legacy Codex limits in resolver fallbacks and model listing. (#37876) thanks @yuweuii.
+- Telegram/compaction replay dedupe: keep cross-turn duplicate suppression for real delivered reply text while avoiding directive-only chunks and non-block compaction retries that could drop or mis-thread replayed Telegram replies. (#39456) Thanks @eveiljuice.
 - Tools/web search: restore Perplexity OpenRouter/Sonar compatibility for legacy `OPENROUTER_API_KEY`, `sk-or-...`, and explicit `perplexity.baseUrl` / `model` setups while keeping direct Perplexity keys on the native Search API path. (#39937) Thanks @obviyus.
 - Agents/failover: detect Amazon Bedrock `Too many tokens per day` quota errors as rate limits across fallback, cron retry, and memory embeddings while keeping context-window `too many tokens per request` errors out of the rate-limit lane. (#39377) Thanks @gambletan.
 - Mattermost replies: keep `root_id` pinned to the existing thread root when an agent replies inside a thread, while still using reply-target threading for top-level posts. (#27744) thanks @hnykda.
