SDK for PHP 7.4.23

Hi guys. We used to have PHP 7.1 and therefore couldn’t use the latest PHP SDK and sentry.io is telling me that I’m using an outdated SDK… Our server’s PHP got updated to 7.4 now so I’m thinking of upgrading our Sentry PHP SDK. What would be the SDK version I could use for composer so that I at least have close to the latest SDK available?
