 ### Fixes
 
+- Dashboard/chat UI: stop reloading full chat history on every live tool result in dashboard v2 so tool-heavy runs no longer trigger UI freeze/re-render storms while the final event still refreshes persisted history. (#45541) Thanks @BunsDev.
 - iMessage/remote attachments: reject unsafe remote attachment paths before spawning SCP, so sender-controlled filenames can no longer inject shell metacharacters into remote media staging. Thanks @lintsinghua.
 - Telegram/webhook auth: validate the Telegram webhook secret before reading or parsing request bodies, so unauthenticated requests are rejected immediately instead of consuming up to 1 MB first. Thanks @space08.
 - Build/plugin-sdk bundling: bundle plugin-sdk subpath entries in one shared build pass so published packages stop duplicating shared chunks and avoid the recent plugin-sdk memory blow-up. (#45426) Thanks @TarasShyn.
