# Cline CLI 3.0.55: Hub stability, auto-update race fixes, streaming markdown, Crusoe provider

> Cline CLI fixes critical auto-update race conditions that could kill live sessions, brick a running session, or cause two Cline installations to fight over the Hub daemon. Streaming markdown no longer flashes back to raw text. Web search calls from native-search models now render in the transcript. The model catalog is refreshed with Crusoe as a new provider. Plugin sandbox processes are reclaimed instead of lingering.

## What changed


- **fix**: Auto-updates no longer install while a CLI is attached to the Hub — update is recorded at startup, applied on exit after Hub confirms nothing else is attached. Fixes `Hub connection closed (code=1006)` from background updates swapping the package out mid-session
- **fix**: `cline update` still installs immediately and now tells you the update applies on next start
- **fix**: Protection for updates landing under CLI 3.0.54 and earlier — the updater restarted the Hub mid-session then rejected every replacement, bricking the session. New install defuses that path
- **fix**: Two Cline installations on different builds no longer shut each other's Hub daemon down in a loop, killing all live sessions. Build identity compared through a total order (from SDK v0.0.75)
- **fix**: A newer build no longer replaces a Hub that is still serving sessions — it attaches and the swap happens on a later launch (from SDK v0.0.75)
- **fix**: Removed "outdated Hub" notice — it reported a state users cannot act on and rendered cut off at every terminal width
- **fix**: Streaming assistant markdown no longer flashes back to raw text; settled headings, links, and code stay rendered as chunks arrive
- **fix**: Transcript no longer jumps vertically mid-stream
- **feat**: Web search calls and results from native-search models now render in the transcript (from SDK v0.0.75)
- **fix**: Idle plugin sandbox processes are reclaimed instead of lingering for the session's life (from SDK v0.0.75)
- **fix**: `cline doctor fix` reports honestly — separates processes that survived a kill from ones that appeared while the fix ran, names a live parent respawning a daemon, reports startup lock as held rather than leaked (from SDK v0.0.75)
- **feat**: Refreshed model catalog — adds Crusoe as a provider, updates model lists and per-provider default models (from SDK v0.0.75)
