### Breaking Changes
92+
Leveraging database real-time hooks, schema caching has been drastically improved. These improvements allows for reduced calls to the DB, faster queries and prevention of memory leaks. A breaking change can occur if you are horizontally scaling Parse Server (multiple Parse Server instances connecting to the same DB). Set `databaseOptions: { enableSchemaHooks: true }` parameter in [Parse Server Options](https://parseplatform.org/parse-server/api/master/ParseServerOptions.html) (`enableSingleSchemaCache` and `schemaCacheTTL` have been removed). If you are horizontal scaling instances connected to MongoDB, you must use replica set clusters with WiredTiger, see [ChangeStream](https://docs.mongodb.com/manual/changeStreams/#availability)
93+
94+
The new schema cache uses a singleton object that is stored in-memory. In a horizontally scaled environment, if you update the schema in one instance the DB hooks will update the schema in all other instances. `databaseOptions: { enableSchemaHooks: true }` enables the DB hooks. If you have multiple server instances but `databaseOptions: { enableSchemaHooks: false }`, your schema maybe out of sync in your instances (resyncing will happen if an instance restarts). (Diamond Lewis, SebC) [#7214](https://github.com/parse-community/parse-server/issues/7214)
9295
- Added file upload restriction. File upload is now only allowed for authenticated users by default for improved security. To allow file upload also for Anonymous Users or Public, set the `fileUpload` parameter in the [Parse Server Options](https://parseplatform.org/parse-server/api/master/ParseServerOptions.html) (dblythy, Manuel Trezza) [#7071](https://github.com/parse-community/parse-server/pull/7071)
9396
### Notable Changes
9497
- Added Parse Server Security Check to report weak security settings (Manuel Trezza, dblythy) [#7247](https://github.com/parse-community/parse-server/issues/7247)
