firebase-ios-sdk/Firebase/Database/CHANGELOG.md

v6.0.0

• [removed] Remove deprecated childByAppendingPath API. (#2763)

v5.1.1

• [fixed] Fixed crash in FSRWebSocket. (#2485)

v5.0.2

• [fixed] Fixed undefined behavior sanitizer issues. (#1443, #1444)

v4.1.5

• [fixed] Fixes loss of precision for 64 bit numbers on older 32 bit iOS devices with persistence enabled.
• [changed] Addresses CLANG_WARN_OBJC_IMPLICIT_RETAIN_SELF warnings that surface in newer versions of Xcode and CocoaPods.

v4.1.4

• [added] Firebase Database is now community-supported on tvOS.

v4.1.3

• [changed] Internal cleanup in the firebase-ios-sdk repository. Functionality of the RTDB SDK is not affected.

v4.1.2

• [fixed] Addresses race condition that can occur during the initialization of empty snapshots.

v4.1.1

• [fixed] Fixed warnings for callback types with missing argument specifications in Xcode 9.

v4.1.0

• Added multi-resource support to the database SDK.

v4.0.3

• [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.

v4.0.2

• [fixed] Retrieving a Database instance for a specific FirebaseApp no longer returns a stale instance if that app was deleted.
• [changed] Added message about bandwidth usage in error for queries without indexes.

v4.0.1

• [changed] We now purge the local cache if we can't load from it.
• [fixed] Removed implicit number type conversion for some integers that were represented as doubles after round-tripping through the server.
• [fixed] Fixed crash for messages that were send to closed WebSocket connections.

v4.0.0

• [changed] Initial Open Source release.

v3.1.2

• [changed] Removed unnecessary _CodeSignature folder to address compiler warning for "Failed to parse Mach-O: Reached end of file while looking for: uint32_t".
• [changed] Log a message when an observeEvent call is rejected due to security rules.

v3.1.1

• [changed] Unified logging format.

v3.1.0

• [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.

v3.0.3

• [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.
