 ## Unreleased
 
+## 0.39.0 (2026-06-09)

 - **Refreshed TUI theme and Catppuccin syntax highlighting.** The interface adopts a brand periwinkle/indigo accent (`#B3B9F4` dark / `#0B114E` light) with a reharmonized selection tint, and code blocks now highlight with Catppuccin Mocha (dark) / Latte (light), adaptive to the active theme — implemented as foreground-only Pygments styles with no new dependency. Markdown inline code and links render terminal-native cyan, blockquotes green, and ordered-list markers bright blue (so they adapt per terminal), and user messages sit on a neutral grey block instead of the prior blue tint.
-- **Homebrew updater no longer no-ops or false-reports success.** `pythinker update` on a Homebrew install now runs `brew update` to refresh the tap before `brew upgrade`, so a stale local tap clone can't pin the old formula and silently no-op ("0.37.0 already installed"). After upgrading it re-checks the installed version via `brew list --versions` and reports a clear failure instead of "Updated successfully!" when the version did not actually advance.
+- **Homebrew updater no longer no-ops or false-reports success.** `pythinker update` on a Homebrew install now runs `brew update` to refresh the tap before `brew upgrade`, so a stale local tap clone can't pin the old formula and silently no-op ("0.38.0 already installed"). After upgrading it re-checks the installed version via `brew list --versions` and reports a clear failure instead of "Updated successfully!" when the version did not actually advance.
 - **Friendlier usage-limit (429) messages and ChatGPT account switching.** When a provider returns a 429, Pythinker now renders a human-readable notice — the plan name, the reset window, and a dimmed `Server:` detail line (all markup-escaped) — instead of a raw error string. `/login` for ChatGPT now uses `prompt=login`, so you can switch between ChatGPT accounts instead of being silently kept on the previous session.
 - **Agent phase-0 enhancements.** Adds a model-invocable cross-session Recall tool (search and read prior sessions on demand, sanitized and read-only for subagents), read-only MCP resources/prompts surfaced as tools, project-scoped `.pythinker/mcp.json` layering, subagent token/cost roll-up to the orchestrator, and truncated tool output that spills to disk with a recovery hint instead of being lost.
 - **No more spurious `coroutine … was never awaited` warnings.** Dropped Sentry's `AsyncioIntegration`, whose `create_task` monkeypatch wrapped every coroutine and — when a task was cancelled before its first step during turn/prompt teardown — orphaned the inner coroutine, printing `WireUISide.receive` and prompt_toolkit "never awaited" `RuntimeWarning`s to the console. The integration added no spans (tracing/profiling are off), and exception capture for async tasks is preserved by the existing asyncio exception handler.
 - **Read-only profile guard hardened against version-pinned interpreters.** Inline-code interpreter invocations that use a version-suffixed or absolute binary (`python3.14 -c …`, `/usr/bin/python3.12 -c …`, `node20 -e …`) are now classified as mutating/destructive just like the bare `python`/`node` forms, so they can no longer bypass a read-only subagent profile or skip destructive deliberation.
 - **The agent sets up and removes MCP servers on request instead of refusing.** Asked to add, remove, or set up an MCP server, the default agent now knows it runs in Pythinker: it configures the server with the `pythinker mcp add`/`remove` CLI (or by editing `~/.pythinker/mcp.json` / `./.pythinker/mcp.json`), verifies with `pythinker mcp list`/`test`, and tells you to restart or `/reload` to load the change — rather than refusing or citing Claude Code/Desktop config paths (`~/.claude.json`) it cannot use. The prompt now also hard-steers the agent away from writing `mcpServers` into `~/.pythinker/config.yaml` (YAML is never parsed for MCP, so such an entry is silently dropped and the server never appears in `/mcp`). As a backstop, MCP config loading now logs a warning when it finds an `mcpServers` block in a `config.yaml` (global or project), so a human or agent that misplaces it gets a diagnosable trace instead of a silent drop.
 - **Security: dependency vulnerability remediation.** Cleared the open Dependabot advisories across all manifests. Python: `asyncssh` 2.22.0 → 2.23.0 (path-traversal in `AuthorizedKeysFile %u`) in the `pythinker-host` pin and both lockfiles, and `starlette` 1.0.0 → 1.2.1 (Host-header path poisoning). JS: regenerated the `web`, `vis`, and `install-counter-worker` lockfiles and bumped the worker's `vitest` to `^3.2.6` (critical Vitest UI arbitrary file read/exec), clearing all critical/high/moderate advisories. The only residual is a handful of low-severity transitive `elliptic`/`bn.js` advisories in `web`'s browser crypto polyfill chain, left unforced because the fix downgrades `vite-plugin-node-polyfills` and majors `ai`, breaking the build for marginal benefit.

 - **Quieter `/login`.** Logging in no longer prints a `RuntimeWarning` about an un-awaited `redraw_in_future` coroutine. The prompt redraw throttle now uses a coroutine-free path (`max_render_postpone_time`), eliminating the warning emitted during the login prompt handoff.

-- **Quieter `/login`.** The login prompt handoff no longer emits a `RuntimeWarning` about an un-awaited `redraw_in_future` coroutine; the redraw throttle now uses a coroutine-free path.
-- **Alibaba `/usage` reporting.** A dedicated Alibaba usage adapter means an Alibaba login now produces a populated cost/quota panel instead of the no-adapter fallback.
-- **Live pricing from models.dev.** `/usage` and the session stats panel pull per-model pricing from the models.dev catalog (cached 24h) for more accurate cost estimates.
-- **More robust ripgrep resolution.** File search verifies a bundled `rg` can actually run on the host platform and architecture before using it, falling back to a system or freshly downloaded ripgrep otherwise.
