 # Changelog
 
+- **Changed** Cached tasks are now spawned with `FORCE_COLOR=1` so captured output is always coloured; the reporter strips colours at the writer level when the user's terminal does not support them. Color-related env vars (`NO_COLOR`, `COLORTERM`, `TERM`, `TERM_PROGRAM`) are no longer passed through by default; tasks that need them can opt in via `env`/`untrackedEnv`. Color support is detected per stdio stream, so a redirected stdout no longer strips colour from an interactive stderr ([#378](https://github.com/voidzero-dev/vite-task/pull/378))
 - **Added** `output` field for cached tasks: archives matching files after a successful run and restores them on cache hit ([#375](https://github.com/voidzero-dev/vite-task/pull/375))
 - **Fixed** Windows cached tasks can now run package shims rewritten through PowerShell; default env passthrough now preserves `PATHEXT` ([#366](https://github.com/voidzero-dev/vite-task/pull/366))
 - **Added** Platform support for targets without `input` auto-inference (e.g. Android). Tasks still run; those relying on auto-inference run uncached, with the summary noting that `input` must be configured manually to enable caching ([#352](https://github.com/voidzero-dev/vite-task/pull/352))
