NEW OpenClaw Update is HUGE!

OpenClaw 3.13 ships 60+ changes from 20+ contributors, headlined by a ~50% memory reduction.

## Browser automation is no longer flaky The batch act dispatch system is now normalized with proper selector support, fixing the unreliability of multi-element form fills and button clicks. Failure detection and limits are enforced, and the session lifecycle is hardened against the "stale session" crash where an agent thought a browser was open when it had actually died. If you scrape or do long-running test flows, this is the update you've been waiting for.

## Docker and infra get real hardening A new OPENCLAW_TZ env var gives you explicit timezone control inside containers — no more mystery scheduling. Gateway token leaks during Docker builds are closed, apt-get upgrade now runs in every Dockerfile, and updater refresh logic is cleaner. Bonus for Mac users: Port Guard no longer kills Docker Desktop processes.

## Messaging fixes are uneven Slack has interactive reply directives, but the creator flags community reports that "Slack completely broke their tool" — verify before you upgrade. Telegram gets an IPv4 fallback for media; Discord gracefully recovers from gateway metadata fetch failures (the crash "we almost always see, especially 2–3 weeks ago"). Feishu gets event-level dedup to kill the double-message bug.

## Model and memory controls user compatibility flags are respected across all providers, so configured settings won't be silently overridden. Ollama hides native reasoning output unless toggled on. Sessions now preserve last account ID and last thread ID on reset, Windows/Mac duplicate-memory bugs are fixed, and Anthropic thinking blocks are dropped on replay.

## The headline win: ~50% memory reduction Four optimizations — plugin SDK deduplication (2x memory regression fix), improved cron isolation, gateway bounding, and better lifecycle management — cut RAM roughly in half. The creator calls it "transformative" for mini-PC and local-machine users where memory leaks were making agents "progressively dumber" over long sessions. Not a full fix, but "50% less dumb."

## Misc but worth knowing Dashboard reload storms, oversized chat overflow, and the scroll pill indicator are fixed. Plugin schema gains collision detection that "fails fast" instead of producing mysterious errors.
