[trellis v1.30.0 released](https://github.com/roots/trellis/releases/tag/v1.30.0)

## What’s Changed

### Disable PHP OPcache JIT by default

PHP 8.3’s JIT tracing mode has known memory corruption bugs that can cause recurring PHP-FPM worker crashes. Since WordPress workloads see negligible benefit from JIT, it’s now disabled by default.

Users who want JIT can re-enable it via `group_vars`:

```
php_opcache_jit: 'tracing'
php_opcache_jit_buffer_size: 256M
```

Background: [PHP 8.3 JIT tracing — recurring crash at theme.php:325 (4GB allocation)](https://discourse.roots.io/t/php-8-3-jit-tracing-recurring-crash-at-theme-php-325-4gb-allocation/30241)

### Add support for Composer custom-headers authentication
