+# 0.2.16
+
+## Features
+
+- **New segments compaction mode** writes per-segment markdown files that the model can read to recover pre-compaction detail.
+- **Claude and Cursor compatibility scanning** (skills, rules, AGENTS.md) can now be toggled individually via env vars or config.toml.
+- **grok inspect** now shows the resolved on/off state and source for every Claude/Cursor compatibility toggle.
+- **Cursor MCP servers and hooks** are now discovered and can be disabled independently via GROK_CURSOR_MCPS_ENABLED / GROK_CURSOR_HOOKS_ENABLED.
+
+## Bug Fixes
+
+- **Streaming tool output** (bash/write_file) now renders completely in the pager instead of only the latest chunk.
+- **Streaming bash tool output** now appears correctly in the pager scrollback.
+- **Routing a native tool** (e.g. scheduler_create) through use_tool now gives a clear corrective error instead of an unrecoverable loop.
+- **"Starting session..."** spinner no longer gets stuck when zero MCP servers are configured.
+- **Subagents** now use the correct harness after switching models mid-session.
+- **Fixed long startup delays** when an external auth provider binary hangs or fails.
+- **Subagent conversations** no longer receive unrelated monitor events or background task completions from the parent.
+- **The /loop command** now accepts natural-language intervals instead of always defaulting to 10 minutes.
+- **Fixed blank output** on completed bash or code-execution cards after shell restart or reconnect.
+
+## Performance
+
+- **Large pasted images** no longer bust the prompt cache or exceed the 50 MiB request limit.
