- [feature] The SDK can now infer a default database URL if none is provided in
the config.
# v6.4.0
- [changed] Functionally neutral source reorganization. (#5861)
# v6.2.2
- [fixed] Addressed crash that prevented the SDK from opening when the versioning file was
corrupted. (#5686)
- [changed] Added internal HTTP header to the WebChannel connection.
# v6.2.1
- [fixed] Fixed documentation typos. (#5406, #5418)
# v6.2.0
- [feature] Added `ServerValue.increment()` to support atomic field value increments
without transactions.
# v6.1.4
- [changed] Addressed a performance regression introduced in 6.1.3.
# v6.1.3
- [changed] Internal changes.
# v6.1.2
- [fixed] Addressed an issue with `NSDecimalNumber` case that prevented decimals with
high precision to be stored correctly in our persistence layer. (#4108)
# v6.1.1
- [fixed] Fixed an iOS 13 crash that occured in our WebSocket error handling. (#3950)
# v6.1.0
- [fixed] Fix Catalyst Build issue. (#3512)
- [feature] The SDK adds support for the Firebase Database Emulator. To connect
to the emulator, specify "http://<emulator_host>/" as your Database URL
(via `Database.database(url:)`).
If you refer to your emulator host by IP rather than by domain name, you may
also need to specify a namespace ("http://<emulator_host>/?ns=<namespace>"). (#3491)
# 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](https://firebase.google.com/docs/database/usage/sharding) 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.
