MeowEco Economy 26.10.7

This release adds reliable balance consistency for networks running multiple Paper servers against one shared MySQL database.

Added

• Added atomic balance snapshots so balance and frozen funds are read together from the shared database.
• Added real MySQL regression coverage using two independent plugin database instances.

Changed

• Classic Vault balance reads now use MySQL as the source of truth instead of a process-local read cache.
• Multi-instance shared-MySQL deployments are now explicitly supported and documented.

Fixed

• Fixed stale Vault balances when one Paper server changed an account that another server had recently read.
• Fixed a MySQL concurrency edge case that could roll back one of two valid simultaneous deposits.
• Added deterministic account lock ordering to prevent deadlocks during opposing transfers while preserving total balances.

Verification

• Passed 25 rounds each of concurrent withdrawals, concurrent deposits, and opposing transfers through two independent connection pools on MySQL 8.4.
• Verified that committed balance and frozen-fund changes are immediately visible to the other instance.
• Passed the complete Gradle check suite, including SQLite, migration, Classic Vault, VaultUnlocked v2, and Paper compatibility checks.

Compatibility

• Paper 26.1.x / 26.2 / 26.3
• Java 25
• Classic Vault remains supported.
• VaultUnlocked v2 remains available as an optional integration.

Download

• Download the compiled plugin JAR from Modrinth versions.
• GitHub hosts the source code and issue tracker.
