MeowEco 26.9.1 Changelog

Release date: 2026-06-29

🚀 Highlights

MeowEco 26.9.1 is a performance maintenance release for Paper 26.1.x / 26.2 servers. It focuses on reducing Vault default-currency balance read pressure.

Many shop, menu, permission, quest, and display plugins query balances through Vault very frequently. This release adds a very short read cache for Vault default-currency balance lookups, reducing repeated database reads while keeping all money-changing operations database-authoritative.

✨ Added

• ⚡ Added a short Vault default-currency balance read cache for frequent getBalance / has calls from external Vault consumers.
• 🧾 Added 26.9.1 release notes explaining the cache strategy, intended use, and safety boundaries.
• 🧹 Player quit now clears that player's Vault cache entries to avoid stale cache growth on long-running servers.
• 🧪 Added a Paper 26.1.2 stable API compatibility compile gate alongside the existing earliest 26.1.x guard and Paper 26.2 main compile target.

🔄 Changed

• ☕ Bumped the plugin version to 26.9.1.
• 🔁 Successful Vault, MeowEco API, admin command, pay/exchange, join-time account creation, and rich-tax write paths now invalidate the related Vault balance cache.
• 🧠 Player-level cache invalidation now removes every Vault cache key for that player instead of relying on the current default-currency setting.
• 📦 Release verification now covers the earliest Paper 26.1.x API, Paper 26.1.2 stable API, and the Paper 26.2 main target API.

🛠️ Fixes And Improvements

• 🛡️ The cache is read-only and only applies to Vault default-currency reads; deposits, withdrawals, and account creation still go directly to the database.
• 🔒 Vault withdrawals remain database-authoritative, so insufficient funds are rejected by the atomic database update instead of by cached reads.
• 🧽 Cleaned README trailing whitespace while preserving the emoji-led marketplace introduction layout.

🌟 Why Upgrade

• 🏪 Lower database pressure when shop, menu, VIP, and reward plugins repeatedly check balances.
• 📊 Lighter balance displays, requirement checks, and menu refreshes.
• 🔌 Better Vault behavior for high-interaction servers.
• 🛡️ Performance gains without weakening economy safety.
