Compatibility and security

Fetch	NativePHP Mobile	Android	iOS
1.x	^4.1 (all compatible 4.x releases)	✅	✅

Fetch 1.x requires NativePHP Mobile ^4.1. This Composer constraint supports NativePHP Mobile 4.1 and compatible later 4.x releases while excluding 5.0 and other future major versions. New NativePHP Mobile 4.x releases are checked on Android and iOS as part of ongoing plugin maintenance.

• Requires PHP 8.4+, Android API 29+, and iOS 18+.
• Android uses OkHttp 4.12.0 and requests android.permission.INTERNET.
• iOS uses Foundation URLSession with no external networking dependency.
• Authorization values, request bodies, and file contents are not logged.
• Concurrent requests are supported.
• Upload paths must be readable and download destinations must be writable.
• Downloads use destination locking, temporary partial files, cleanup, and explicit overwrite consent.

Validate untrusted URLs and avoid forwarding authorization headers to hosts you do not control. Retrying non-idempotent operations may repeat server-side effects.
