## [1.0.0] - Official Release (Current) ### Architectural Overhaul - **Node-Based Multi-Group Architecture**: Deprecated the rigid single `primary_group` system. Groups are now dynamically resolved by looking for active personal permission nodes starting with `group.`. - **Multi-Group Merging**: If a player holds multiple groups (e.g., `group.vip` and `group.mod`), the engine seamlessly merges both groups and their inheritance trees, automatically prioritizing prefixes based on group weights. - **Contextual Groups**: Full native support for Server-Specific groups and Temporary Ranks (all utilizing native permission node logic). ### Performance Upgrades - **O(1) Permission Caching**: Integrated a blazing-fast memory cache directly into the `User` model. Bukkit and Velocity now instantly resolve permission queries (`hasPermission()`) by checking the memory cache, completely bypassing expensive Regex evaluation and node parsing. - **Optimized Footprint**: Reduced the compiled plugin JAR size by over 84% (from 17MB down to 2.8MB) by switching heavy SQLite and MariaDB drivers to `compileOnly`, leveraging the server's native runtime libraries instead. ### Command Overhauls - **Group Management**: Completely replaced the old `/ola user parent set ` command suite with a far more powerful node-based command suite: - `/ola user group add [duration] [server]` - `/ola user group remove [server]` - `/ola user group list` - **Quality of Life**: Added deletion and inspection commands: - `/ola group delete` - `/ola track delete` - `/ola group list` - `/ola track list` - **Tab-Completer AI**: Fully rewrote the auto-completion logic to guide users through the new Multi-Group syntax perfectly. ### Developer API & Integrations - **Platform-Agnostic Event Bus**: Engineered a comprehensive custom Event Bus into the `OlaPermissionsAPI`. - **30 Granular Events**: Developers can now listen to an unprecedented level of engine detail on both Paper and Velocity, including: - Track progression (`UserPromoteEvent`, `UserDemoteEvent`) - Node manipulation (`NodeAddEvent`, `NodeRemoveEvent`) - Cross-server networking (`NetworkSyncEvent`) - Context recalculations (`ServerContextSwitchEvent`, `WorldContextSwitchEvent`) - Infrastructure sweeps (`MigrationCompleteEvent`) - **OlaVaultChatProvider**: Natively integrated Vault chat formatting hooks. External chat formatting plugins (like EssentialsChat) will now automatically traverse a user's multi-group inheritance tree to find and display the prefix with the highest weight.
