## Unreleased
-- Added an explicit "reduction ladder" and deliberate-shortcut guidance to the default agent prompt so the agent reaches for the simplest working solution (stdlib/native before custom code) by default.
-- Added a `cleanup-audit` skill: a read-only, whole-repo pass that ranks over-engineering to delete, simplify, or replace with standard-library/platform equivalents (the repo-wide complement to `pythinker review diff --mode deslopify`).
+## 0.49.0 (2026-06-20)

+- **Reduction ladder in the default agent prompt.** The agent now walks an explicit,
+ ordered ladder before writing code — does this need to exist at all, then the standard
+ library, a native platform or framework feature, an already-installed dependency, one
+ line, and only then the minimum custom code — so it reaches for the simplest working
+ solution by default. The same guidance is mirrored into the `/best-practices` profile,
+ and deliberate shortcuts with a known ceiling are flagged with a comment naming the
+ ceiling and the upgrade path. Input validation, error handling, security, and
+ accessibility are never traded away for fewer lines.
+- **New `cleanup-audit` skill.** A read-only, whole-repo pass that ranks over-engineering
+ — what to delete, simplify, or replace with standard-library/platform equivalents — as
+ the repo-wide complement to the diff-scoped `pythinker review diff --mode deslopify`. It
+ applies no fixes and never proposes cutting validation, error handling, security, or
+ accessibility.
- **Fix: duplicate update notices at startup.** When a background install finishes
or a cached update is detected, the hint now renders only on the persistent
under-input line instead of also flashing as a footer toast.

-## 🆕 What's New in 0.48.0
+## 🆕 What's New in 0.49.0
-- **LSP code intelligence.** New `LSP` tool (go-to-definition, references, hover, symbols, call hierarchy) with plugin-backed language servers, session-scoped lifecycle, passive diagnostics after edits, and structured errors when a server lacks `implementationProvider`.
-- **TUI theme and streaming overhaul.** Centralized theme system (`/theme`), 25 Hz paced streaming, syntax-highlighted diff cards, report panel polish, and smoother interactive/non-interactive live views — no preamble ghosting, mid-stream scrollback flicker, or fossilized spinners during tool transitions.
-- **Proxy and tool-call hardening.** Tool results flatten for Anthropic-compatible proxies (fixes invisible GLM/z.ai outputs); `ToolSearch` is hidden from providers that cannot use deferred discovery; diff cards strip ANSI escapes; collapsed ReadFile cards show line counts and previews.
+- **Cleaner code by default.** The agent now walks an explicit *reduction ladder* before writing code — does this need to exist at all, then the standard library, a native platform or framework feature, an already-installed dependency, one line, and only then the minimum custom code — so it reaches for the simplest working solution without trading away input validation, error handling, security, or accessibility. The same guidance layers into the `/best-practices` profile.

+- **Smoother startup.** Update notices no longer appear twice; the hint now renders once on the persistent under-input line instead of also flashing as a footer toast.
