 - Ollama/custom provider headers: forward resolved model headers into native Ollama stream requests so header-authenticated Ollama proxies receive configured request headers. (#24337) thanks @echoVic.
 - Daemon/systemd install robustness: treat `systemctl --user is-enabled` exit-code-4 `not-found` responses as not-enabled by combining stderr/stdout detail parsing, so Ubuntu fresh installs no longer fail with `systemctl is-enabled unavailable`. (#33634) Thanks @Yuandiaodiaodiao.
 - Slack/system-event session routing: resolve reaction/member/pin/interaction system-event session keys through channel/account bindings (with sender-aware DM routing) so inbound Slack events target the correct agent session in multi-account setups instead of defaulting to `agent:main`. (#34045) Thanks @paulomcg, @daht-mad and @vincentkoc.
+- Slack/native streaming Markdown rendering: remove pre-normalization from the native `markdown_text` streaming path (`start/append/stop`) so Markdown content is not double-converted before Slack rendering. (synthesis from #34931, #34759, #34716, #34682, #34814) Thanks @littleben, @dunamismax, @Octane0411, @carrotRakko, and @RealKai42.
 - Gateway/HTTP tools invoke media compatibility: preserve raw media payload access for direct `/tools/invoke` clients by allowing media `nodes` invoke commands only in HTTP tool context, while keeping agent-context media invoke blocking to prevent base64 prompt bloat. (#34365) Thanks @obviyus.
 - Agents/Nodes media outputs: add dedicated `photos_latest` action handling, block media-returning `nodes invoke` commands, keep metadata-only `camera.list` invoke allowed, and normalize empty `photos_latest` results to a consistent response shape to prevent base64 context bloat. (#34332) Thanks @obviyus.
 - TUI/session-key canonicalization: normalize `openclaw tui --session` values to lowercase so uppercase session names no longer drop real-time streaming updates due to gateway/TUI key mismatches. (#33866, #34013) thanks @lynnzc.
