You might want to use v5 since the encryption sometimes fails on certain machines. @Spomky is currently looking at this.

• Support Guzzle 7 (and thus Laravel 8) (thx @martijnb92!) : a specific PR to decouplate web-push-php from Guzzle and use psr/http-client is most welcome 🙏🏻
• Hotfix for encryption (thx @Spomky!)

• [Breaking Change] New API : sendOneNotification and queueNotification (see Usage in README)
• [Breaking Change] PHP 7.2+ is now required

• Remove deprecated GCM auth support (thx @BR0kEN-!)

• Added SubscriptionInterface (thx @BR0kEN-!)
