## Description

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.

## Installation

 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.

## Changelog

#### 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.
