## Overview

Recently shipped Vitest 5.0.4 with trace-view selector highlighting, a `--changed` test count, and a `test.ui.theme` option.

**Trace view got sharper.** When several elements match a selector in trace view, each match is now highlighted. The attempts selector sits in the viewer header, with a focused layout mode that collapses surrounding chrome. Trace state persists across keyboard navigation of steps, with links out to Playwright traces, and the VS Code extension opens trace view directly.

**`--changed` now says how much it touched.** Runs print the number of affected tests plus a total.

**Config and defaults kept moving.**
- A `test.ui.theme` option sets the UI theme.
- Cache directories can be tagged with `CACHEDIR.TAG`.
- Assertion inspection uses pretty-format; `test.for/each` `$` titles no longer quote string values.
- Attachments moved to `.vitest/attachments/`.
- Nested projects are supported, `clearCache` and `parseSpecifications` graduated out of experimental, and coverage runs on `@vitest/istanbuljs`.

**Patch wrap-up.** v5.0.2 and v5.0.3 bound `process` when a global overwrites it, fixed `toMatchObject` with asymmetric matchers, isolated `result.status` between `repeats` runs, and stopped retrying when `test.fails` already failed. The VS Code extension no longer crashes on newer editor versions.
