This removes the implicit dependency on EssentialsX or any economy plugin from the default configuration.
Improved
Improved the config migration system so legacy unsupported commands can be patched not only in daily rewards, but also in:
fallback rewards
streak bonus rewards
Existing configs using the old eco give %player% 500 streak bonus can now be migrated automatically.
Fixed
/rewards reset <player> now saves player data immediately after resetting.
/rewards setstreak <player> <amount> now saves player data immediately after modifying the streak.
Notes
Economy-based rewards are still possible, but server owners must configure them intentionally and install a compatible economy setup if they want to use economy commands.
