+<Update label="2.1.237" description="August 20, 2026">
+  * Fixed prompt caching for sessions using an LLM gateway or custom base URL
+  * Added a built-in "Concise" output style: Claude leads with results and skips preamble and narration, while doing the work just as thoroughly. Select it under Output style in /config.

 <Update label="2.1.236" description="August 19, 2026">
   * Added `ANTHROPIC_DEFAULT_MODEL` environment variable: sets the model new sessions start on, while a `/model` pick still overrides it and persists across restarts (unlike `ANTHROPIC_MODEL`)
   * Added `notify_when_idle` to cross-session `SendMessage`: ask another Claude Code session on this machine to send one notice when it next goes idle — opt-in, one-shot, no polling (macOS and Linux)

   * Fixed unauthorized claude.ai MCP connectors showing as "failed" instead of "needs auth", and headless `-p` mode retrying non-transient 4xx connection failures
   * Improved visual consistency in slash command dialogs and `/login`, `/upgrade`, `/extra-usage` dialog spacing
   * Updated the `/tui fullscreen` startup banner to describe additional renderer benefits (lower memory usage, mouse support, auto-copy on select)
-  * Fixed Bedrock and Vertex 400 errors when `ENABLE_PROMPT_CACHING_1H` is set
