# Savs Common Economy v1.6.1 Release Notes
## ⚠️ Important
**If you are updating an existing server:** This update is a full rewrite to support Minecraft 26.1.
While it is fully backward compatible, we recommend backing up your `config` folder and `database` (if using one) before upgrading.
* Your existing `savs-redis.json`, `worth.json`, and `shops.json` files will automatically migrate to the new formats.
* `Savs-Redis-Lib` is no longer required as a standalone mod and can be safely deleted.
**Please report any bugs or issues on the [Issue Tracker](https://github.com/xSaVageAU/Savs-Common-Economy/issues).**
## New Features
### Minecraft 26.1 Support
The entire codebase has been ported and rewritten for Minecraft 26.1.
### Native Redis Synchronization
Redis PubSub for cross-server balance synchronization is now built natively into the core mod.
### Permissions System
The mod has been updated to interface with the Fabric Permissions API v0.7.0. You can securely control access to all commands via mods like LuckPerms. A `permissions.json` configuration file has also been added as a fallback, letting you adjust the required Vanilla OP Level for commands if you aren't using an external permissions manager.
### Buy & Sell Split Market
Server-direct trading has been expanded. We've added a `/buy` command to complement `/sell`. The `worth.json` configuration now separates `buyPrices` and `sellPrices`. When migrating from old versions, your new `buyPrices` will safely default to double your current sell rates.
## Quality of Life
### Event-Driven Shop Computations
Shop signs have been optimized to use an event-based system. They now only refresh exactly when stock is changed, eliminating the previous background looping scans.
