## 説明

Updating is the most common way a live WordPress site breaks. Azvian
 Preflight 
runs a check _before_ you apply an update — or on any installed plugin or theme 
on demand — and answers two questions about that change:

**Is it safe?**
 A static scan of the code for functions, classes and constants 
that are deprecated or removed in your current or a target PHP version, or a deprecated
WordPress function. You get a `file:line` list and a plain verdict: looks clear /
deprecations found / review before updating. Findings are flagged _usage_, not proof
of breakage — a lot of deprecated calls are safely guarded by version checks — so
the wording stays honest.

**What does it cost?**
 A footprint of the target’s registered CSS/JS: which handles
it owns and what those files weigh, so you have a baseline to compare against after
you update.

Everything runs locally. No account, no external calls, no data leaves your
 site.

#### WP-CLI

    ```
    wp preflight check woocommerce/woocommerce.php --target-php=8.3
    ```

#### Preflight Pro

A separate add-on (from azvian.com, subscription) adds automatic pre-flight
 on 
every update and auto-update, a continuously maintained compatibility dataset (including
per-plugin breaking changes), WordPress-major and PHP-major readiness, custom-code
scanning, real before/after impact diffs with history, and safe-update with automatic
rollback. The free plugin works fully on its own.

## インストール

 1. Install and activate.
 2. Open **Azvian Preflight** in the admin menu.
 3. Run a pre-flight against a pending update, or any installed plugin/theme.

## FAQ

### Does a finding mean the update will break my site?

No. It means the code _uses_ an API that changed. Many such calls are
 guarded by
version checks. Treat findings as “look here”, not “this breaks”.

### Does it phone home?

No. The free plugin uses only the dataset bundled with it.

## 変更履歴

#### 0.1.1

 * Renamed to Azvian Preflight (from Preflight) at the WordPress.org review
    team’s
   request, to avoid naming confusion with existing plugins in the same “preflight”
   naming space (PreFlight Scanner, Site Preflight, and others). No functional changes.

#### 0.1.0

 * First release: static compatibility scanner (functions, constants and
    deprecated
   hooks), asset footprint, run history, admin screen, WP-CLI command, and a bundled
   dataset covering PHP 7.4-8.4 removals/deprecations and WordPress core deprecations.
