v0.9.0

Dragonfly 0.9.0

YOM KIPPUR edition

This is quite significant release with lots of interesting features:

• Epoll support - now we support all Linux kernels !!!
  Dragonfly automatically falls back to epoll API if iouring API is not available for some reason.
  This can also reduce friction when running Dragonfly on k8s (no need to use --privileged flag anymore).
  If you want to force epoll instead of iouring you can do it with --force_epoll flag.
• New Dragonfly specific command SADDEX key seconds member member ... allows adding to sets members with TTL!
• CPU usage is greatly reduced when Dragonfly is in idle mode (~10x reduction).
• Dragonfly can connect to Redis server in SLAVE mode (using replicaof command)
• MOVE, SORT and PERSIST commands are now supported.

Huge thanks to all the contributors! ❤️

A nice release, not very big but things are moving in the right direction.

1. Transactional support is extended to WATCH/UNWATCH by @dranikpg

3. JSON.DEL was added to JSON family by @iko1 .

Huge thanks to all the contributors! ❤️
