4.1.0

• Added multi-resource support to the database SDK.

4.0.3

• [fixed] Fixed a regression in v4.0.2 that affected the storage location of the offline persistent cache. This caused v4.0.2 to not see data written with previous versions.
• [fixed] Fixed a crash in FIRApp deleteApp for apps that did not have active database instances.

4.0.2

3.1.0

• [feature] Reintroduced the persistenceCacheSizeBytes setting (previously available in the 2.x SDK) to control the disk size of Firebase's offline cache.
• [fixed] Use of the updateChildValues() method now only cancels transactions that are directly included in the updated paths (not transactions in adjacent paths). For example, an update at /move for a child node walk will cancel transactions at /, /move, and /move/walk and in any child nodes under /move/walk. But, it will no longer cancel transactions at sibling nodes, such as /move/run.

3.0.3

• [fixed] Fixed an issue causing transactions to fail if executed before the SDK connects to the Firebase Database backend.
• [fixed] Fixed a race condition where doing a transaction or adding an event observer immediately after connecting to the Firebase Database backend could result in completion blocks for other operations not getting executed.
• [fixed] Fixed an issue affecting apps using offline disk persistence where large integer values could lose precision after an app restart.
