OpenClaw: Telegram Improvements and Agent Fixes

Transcript

Good morning, this is OpenClaw development news for May 19th, 2026.

The team merged 20 pull requests yesterday with significant improvements across messaging platforms and core agent functionality.

VACInc merged a major Telegram fix addressing forum topic parallel flow issues. The change improves how Bot API messages handle topic identity and replaces global flush chains with per-topic queues, allowing independent topics to process concurrently.

Galin Iliev contributed multiple agent system improvements, including enhanced trajectory flush timeout diagnostics that help operators identify whether delays are caused by queued writes or file IO operations. Additional fixes address stale subagent completion announcements and duplicate embedded run clears.

Patrick Erichsen added Telegram progress preview flows, introducing generic channel-message flow runners with thinking and working progress labels that render user-friendly status updates.

On the authentication front, FullerStackDev merged xAI OAuth device code login support, enabling remote and VPS-friendly authentication without localhost callbacks.

Josh Avant delivered several fixes including Codex app snapshot guards against plugin invocation failures and preservation of bare Telegram reply context for runtime-only prompts.

Gio Della-Libera improved configuration handling with bundled provider timeout overlays and better Telegram groups config diagnostics.

Other notable merges include Oviemudiaga's WhatsApp delivery queue drain fix preventing messages from waiting until reconnect, and Sarah Fortune's Windows installer improvement to prevent setup freezing.

What's next: The team continues focusing on messaging platform reliability and agent system stability. Additional configuration improvements are in the pipeline.

That's your OpenClaw update for May 19th. Back tomorrow with more development news.
