• TASK: Remove version number from ext-json dependency
• TASK: PHP 7.4 compatibility

Note that Flow 5.3 and up are compatible with PHP 7.4 now!

The released versions are:

• Flow - 5.1.17 ChangeLog
• Flow - 5.2.13 ChangeLog
• Flow - 5.3.9 ChangeLog
• Flow - 6.0.6 ChangeLog

As already announced in Security only reached for Neos 3.3 to 4.2 and Flow 4.3 to 5.2 these are the last regular releases for Flow 5.0 to 5.2, so upgrade to a later version as soon as you can.

Thanks to those who contributed!
