# Changelog

## [Unreleased]

## [0.5.1] - 2026-11-05

### Fork differences

- Footer now merges the live sub-agent tok/s into its display, consuming the `delegate:tps` event.
- Footer-segments tests now assert against the actual model instead of a hard-coded one.

## [0.5.0] - 2026-11-05

### Breaking Changes

- Require Pi 1.5.0 or later.
- `fullscreen.wheelScrollLines` has been removed; wheel speed now follows Pi's own settings. The old config key is still accepted without error but no longer takes effect.

### Upstream sync

- Sync upstream pi-open-tui 0.4.3, including fixes such as the cwd Chinese-name infinite loop; see the upstream CHANGELOG sections 0.3.7–0.4.3 for details.

### Fork differences

- Keep the event-driven working refresh (`workingRefresh.mode`, default `event`) instead of the 250 ms footer timer, so terminal scrollback stays stable while the model works.
- Add the opt-in `terminalTitle.sessionIds` setting that appends `pid=<pid> sid=<sessionId>` to the terminal window title.

## [0.4.3] - 2026-11-05

### New Features

- Let extensions contribute text to either main footer row through the public `open-tui:footer:*` events, with placement, width priorities, lifecycle cleanup, and a separate visibility setting.
- Add opt-in compact rows for extension, MCP, and replacement tools through `toolView.extensionTools`, with generic summaries and native rendering on expansion.
- Add search-specific compact summaries for recognized `@ff-labs/pi-fff` installations, including page match counts, matching file totals, and pagination and fallback hints.
- Allow selected tools, such as `edit`, to keep their native rendering in compact mode through `toolView.exclude`.

### Breaking Changes

- Require Pi 1.5.0 or later.

### Changed

- Group `/open-tui` settings into sections in English and Simplified Chinese, with non-selectable headings and scrolling that includes heading rows.
- Keep feature introductions and usage examples in both READMEs, and move complete configuration and implementation details into bilingual reference documents in `docs/`.

### Fixed

- Show code-block Copy labels as soon as streaming ends, without requiring a terminal resize, and hide them when streaming resumes.
- Preserve each Copy button's code and click region across Markdown block reuse, repeated identical blocks, and mixed cached and new blocks; restore source tabs using the current block occurrence.
- Cancel pending Copy clicks when buttons are disabled, and suppress clipboard notifications from cleaned-up installations.
- Make changed-word highlighting for short edit-preview lines independent of scheduling delays, while keeping matching limits for larger diffs.

## [0.4.2] - 2026-11-03

### Changed

- Cache completed compact tool rows and Copy button labels so scrolling reuses rendered lines instead of rebuilding them.

### Fixed

- Cancel an in-progress Copy click when rendering moves, removes, or changes its Copy target, so a stale press cannot copy different content.

## [0.4.1] - 2026-11-02

### New Features

- Add clickable Copy buttons to fenced code blocks and user messages in fullscreen mode, configurable through `/open-tui`.
- Add syntax-highlighted previews for successful edits and writes in compact tool view, limited to 16 rows with a hint to expand longer output.

### Changed

- Preserve compatible editors installed by other extensions, including runtime replacements, while applying open-tui framing and retaining their input behavior.
- Refine compact tool status indicators with dimmed completed rows, animated running dots, and clearer error and truncation summaries.

### Fixed

- Include tool-reported usage, compaction and branch summaries, and cache warming in footer token and cost totals; show the cache-hit percentage for the latest assistant response.
- Respect `PI_CODING_AGENT_DIR` for settings storage and warn when settings cannot be saved.
- Improve Scala project detection and Git status handling for renamed-then-deleted files.
