Hunk 0.15 adds release benchmark gating, Sapling support, and a run of rendering performance work that keeps large reviews responsive on Windows and Unix alike.

```sh
npm i -g hunkdiff@0.15.3
```

Hunk 0.15 is no longer the current release. See [the latest release](/changelog/) or [all install options](/docs/start/install/).

### 0.15.3

June 13, 2026

#### Added

- Added release benchmark snapshots and a release workflow gate that blocks publishing when committed benchmark results show material performance regressions, with auditable accepted-regression records for intentional release tradeoffs.

#### Fixed

- Fixed Windows launches from Cygwin, Git Bash, and WSL-style VCS paths by normalizing Unix-style repo roots before reusing them as subprocess working directories or filesystem roots.
- Fixed release staging so benchmark comparison artifacts are not mistaken for platform binary artifacts.
- Reduced hunk-navigation latency and memory growth on large reviews by keeping diff geometry memoized when the selected hunk changes.
- Reduced scroll and hunk-navigation latency on large reviews by avoiding repeated separator measurement and preserving memoized offscreen/visible diff rows across viewport updates.
- Reduced main diff pane rendering work on large reviews by virtualizing offscreen file sections behind exact-height spacers.
- Reduced sidebar rendering work on many-file reviews by virtualizing offscreen file rows behind exact-height spacers.

### 0.15.2

June 13, 2026

#### Changed

- Coalesced scroll-position React updates into a single per-frame read and shifted background syntax highlighting from microtasks to timers, so rapid wheel or held-arrow scrolling no longer produces visible jank from per-delta state updates or per-file highlight work starving input and render callbacks.

#### Fixed

- Honored `--transparent-bg` and `transparent_background` in static pager output, so captured pager hosts like LazyGit let translucent terminal backgrounds through on context lines, gutters, and hunk headers while added/removed rows keep their tinted backgrounds.
- Kept menu dropdowns and the help dialog on the base theme in transparent-background mode so popups remain readable over translucent terminals.
- Resolved `hunk session ... --repo <path>` selectors to the containing repo root before matching, so `--repo .` (and any path inside the tree) targets the live session from a subdirectory instead of reporting no match.

### 0.15.1

June 9, 2026

#### Fixed

- Restored the `e` keyboard shortcut and menu hint for opening the selected file in `$EDITOR`.
- Added timeouts to `hunk session *` daemon capability and API calls so unresponsive daemons fail instead of hanging indefinitely.
- Updated OpenTUI so light and dark theme backgrounds render without the native renderer's color shift.
- Prevented Git watch polling from taking optional index locks while discovering untracked files.

### 0.15.0

June 8, 2026

#### Added

- Show the newly selected theme in the footer status bar when switching themes.
- Added Catppuccin Frappé and Macchiato as built-in themes, completing the four official Catppuccin flavors.
- Added a Zenburn built-in theme (`theme = "zenburn"`), a warm low-contrast dark palette inspired by Jani Nurminen's original Zenburn. It also works as a custom-theme `base`.
- Added a `--transparent-bg` flag and `transparent_background` config option for translucent terminal setups.
- Added Sapling VCS backend support for `hunk diff` and `hunk show`.

#### Fixed

- Preserved split diff alignment when horizontal scrolling starts inside a wide CJK or emoji character.
- Made diff syntax highlighting follow the active theme: keyword, function, number, and variable token colors now resolve to the configured theme's palette (including custom themes) in both light and dark, instead of passing through Pierre's built-in syntax colors.
- Expanded the diff window during rapid scrolling bursts so large reviews keep real rows mounted instead of falling back to blank placeholder regions.
