+## [0.3.0] - 2026-04-06
+
+### Added
+- Two-line compact header with live session state: version, history count, filter state, hidden/files toggles, and development summary
+- Persistent history storage between sessions with configurable state path and bounded history size
+- History list rendering in most-recent-first order
+- History filter mode (`/` inside history) with dedicated query and navigation behavior
+- Development info panel (`i`) with git context, detected stack, and suggested commands
+- Configurable open-with menu order via `config.toml`:
+  - `open_with.files`
+  - `open_with.directories`
+- Automatic creation of opener config template when `config.toml` is missing
+- New `opencode` opener support for directory actions
+
+### Improved
+- Filter label highlighting now works consistently in both tree and history filter modes
+- UI color behavior is now explicitly normalized to avoid terminal color bleeding
+- History selection and filtering logic aligned with reversed (most-recent-first) history rendering
+
 ## [0.2.6] - 2026-04-04

 - 📄 Toggle file visibility (`a`) to switch between directories-only and mixed view
 - ⚡ Fast jumps in large lists (`PgUp`/`PgDn`, `Home`/`End`, `g`/`G` in normal mode)
 - 🚀 Contextual `open with` menu (`o`) with app detection based on your environment
 - 🔁 Blocking terminal editors restore the UI state when they exit (`nvim`, `nano`, `less`, `bat`)
+- 🧩 Configurable app menu via `config.toml` with automatic template creation

+
+`cd-browser` reads opener settings from:
+
+- macOS/Linux: `~/.config/cd-browser/config.toml`
+- Windows: `%APPDATA%/cd-browser/config.toml`
+
+If the file does not exist, `cd-browser` creates it automatically with defaults.

+Example:
+
+```toml
+[open_with]
+files = ["code", "open", "antigravity", "nvim", "nano", "less", "bat"]
+directories = ["code", "opencode", "antigravity", "nvim"]
+```
+
+You can reorder or remove entries to customize app priority.
