 # Changelog
 
+## 0.1.48 - 2026-04-05
+
+### Added
+- Provider diagnostics — tap a provider in Settings to see binary path, version, model count, and status at a glance. Helps troubleshoot why an agent type isn't available.
+- Provider snapshot system — daemon now pushes real-time provider availability and model lists to the app, replacing the old poll-based approach. Models and modes update live as providers come online or go offline.
+- Codex question handling — Codex agents can now ask the user questions mid-session (e.g. "which file?") and receive answers inline, matching the Claude Code question flow.
+- Reload tab action — right-click a workspace tab to reload its agent list without restarting the app.
+
+### Improved
+- Model selector redesigned — grouped by provider with status badges, search, and better touch targets on mobile.
+- Enter key now submits question card answers and confirms dictation, matching the expected keyboard flow.
+- Removed noisy agent lifecycle toasts that fired on every state change.
+
+### Fixed
+- Desktop app now resolves the user's full login shell environment at startup, fixing tools like `codex`, `node`, `bun`, and `direnv` not being found when Paseo is launched from Finder or Dock. Terminals spawned by Paseo now inherit the same PATH and environment variables as a normal terminal session. Approach adapted from VS Code's battle-tested shell environment resolution.
+- Input field on running agent screens now correctly receives keyboard focus.
+- Mobile model selector alignment and sizing.
