5.11.0(2019-05-01)

Enhancements

[ObjectServer] Added RealmQuery.includeLinkingObjects(). This is only relevant for Query-based Realms and tells subscriptions to include objects linked through @LinkingObjects fields as part of the subscription as well. Objects referenced through objects and lists are always included as a default. (Issue #6426)
Encryption now uses hardware optimized functions, which significantly improves the performance of encrypted Realms. (Realm Core PR #3241)
Improved query performance when using RealmQuery.in() queries. (Realm Core PR #3250).
Improved query performance when querying Integer fields with indexes, e.g. primary key fields. (Realm Core PR #3272).
Improved write performance when writing changes to disk (Realm Core PR #2927)
Added support for incremental annotation processing added in Gradle 4.7. (Issue #5906).

Fixed

[ObjectServer] Fix an error in the calculation of the downloadableBytes value sent by ProgressListeners.
[ObjectServer] HTTP requests made by the Sync client now always include a Host: header, as required by HTTP/1.1, although its value will be empty if no value is specified by the application.
[ObjectServer] The server no longer rejects subscriptions based on queries with distinct and/or limit clauses.
[ObjectServer] If a user had canCreate but not canUpdate privileges on a class, the user would be able to create the object, but not actually set any meaningful values on that object, despite the rule that objects created within the same transaction can always be modified.
Native crash happening if bulk updating a field in a RealmResult would cause the object to no longer be part of the query result. (Issue #6478, since 5.8.0).

Compatibility

Realm Object Server: 3.21.0-rc1 or later.
File format: Generates Realms with format v9 (Reads and upgrades all previous formats)
APIs are backwards compatible with all previous release of realm-java in the 5.x.y series.

Internal

Updated to Realm Core 5.19.1.
Updated to Relm Sync 4.4.2.
Updated to Object Store commit e4b1314d21b521fd604af7f1aacf3ca94272c19a

5.10.0(2019-03-22)

Enhancements

[ObjectServer] Added 4 new fields to query-based Subscriptions: createdAt, updatedAt, expiresAt and timeToLive. These make it possible to better reason about and control current subscriptions. (Issue #6453)
[ObjectServer] Added the option of updating the query controlled by a Subscription using either RealmQuery.findAllAsync(String name, boolean update), RealmQuery.subscribe(String name, boolean update) or Subscription.setQuery(RealmQuery query). (Issue #6453)
[ObjectServer] Added the option of setting a time-to-live for subscriptions. Setting this will automatically delete the subscription after the provided TTL has expired and the subscription hasn't been used. (Issue #6453)

Fixed

Dates returned from the Realm file no longer overflow or underflow if they exceed Long.MAX_VALUE or Long.MIN_VALUE but instead clamp to their respective value. (Issue #2722)

Compatibility

Realm Object Server: 3.11.0 or later.

5.9.0(2019-01-15)

Enhancements

[ObjectServer] Added ObjectServerError.getErrorType() and ObjectServerError.getErrorType() which returns the underlying native error information. This is especially relevant if ObjectServerError.getErrorCode() returns UNKNOWN. #6364
Added better checks for detecting corrupted files, both before and after the file is written to disk.

Fixed

[ObjectServer] Native errors sometimes mapped to the wrong Java ErrorCode. (Issue #6364, since 2.0.0)
[ObjectServer] Query-based Sync queries involving LIMIT, limited the result before permissions were evaluated. This could sometimes result in the wrong number of elements being returned.
Removed Java 8 bytecode. Resulted in errors like D8: Invoke-customs are only supported starting with Android O (--min-api 26) if not compiled with Java 8. (Issue #6300, since 5.8.0).

5.8.0 (2018-11-06)

This release also contains all changes from 5.8.0-BETA1 and 5.8.0-BETA2.

Enhancements

[ObjectServer] Added Subscription class available to Query-based Realms. This exposes a Subscription more directly. This class is in beta. #6231.
- [ObjectServer] Added Realm.getSubscriptions(), Realm.getSubscriptions(String pattern) and Realm.getSubscription to make it easier to find existing subscriptions. These API's are in beta. #6231
- [ObjectServer] Added RealmQuery.subscribe() and RealmQuery.subscribe(String name) to subscribe immediately inside a transaction. These API's are in beta. #6231
- [ObjectServer] Added support for subscribing directly inside SyncConfiguration.initialData(). This can be coupled with SyncConfiguration.waitForInitialRemoteData() in order to block a Realm from opening until the initial subscriptions are ready and have downloaded data. This API are in beta. #6231
[ObjectServer] Improved performance when merging changes from the server.
[ObjectServer] Added support for timeouts when uploading or downloading data manually using SyncSession.downloadAllServerChanges(long timeout, TimeUnit unit) and SyncSession.uploadAllLocalChanges(long timeout, TimeUnit unit). #6073
[ObjectServer] Added support for timing out when downloading initial data for synchronized Realms using SyncConfiguration.waitForInitialRemoteData(long timeout, TimeUnit unit). #6247
[ObjectServer] Added Realm.init(Context, String) which defines a custom User-Agent String sent to the Realm Object Server when a session is created. Using this requires Realm Object Server 3.12.4 or later. #6267
Added support for ImportFlags to Realm.copyToRealm() and Realm.copyToRealmOrUpdate(). This makes it possible to choose a mode so only fields that actually changed are written to disk. This improves notifications and Object Server performance. #6224
Added support for bulk updating the same property in all objects that are part of a query result using RealmResults.setValue(String fieldName, Object value) or one of the specialized overrides that have been added for all supported types, e.g. RealmResults.setString(String fieldName, String value). #762

5.7.0 (2018-09-24)

Enhancements

[ObjectServer] Devices will now report download progress for read-only Realms which will allow the server to compact files sooner, saving server space. This does not affect the client. You will need to upgrade your Realm Object Server to at least version 3.11.0 or use Realm Cloud. If you try to connect to a ROS v3.10.x or previous, you will see an error like Wrong protocol version in Sync HTTP request, client protocol version = 25, server protocol version = 24.

5.2.0 (2018-06-06)

The feature previously named Partial Sync is now called Query-Based Sync and is now the default mode when synchronizing Realms. This has impacted a number of API's. See below for the details.

Deprecated

[ObjectServer] SyncConfiguration.automatic() has been deprecated in favour of SyncUser.getDefaultConfiguration().
[ObjectServer] new SyncConfiguration.Builder(user, url) has been deprecated in favour of SyncUser.createConfiguration(url). NOTE: Creating configurations using SyncUser will default to using query-based Realms, while creating them using new SyncConfiguration.Builder(user, url) will default to fully synchronized Realms.
[ObjectServer] With query-based sync being the default SyncConfiguration.Builder.partialRealm() has been deprecated. Use ``SyncConfiguration.Builder.fullSynchronization()` if you want full synchronisation instead.

Enhancements

[ObjectServer] Added SyncUser.createConfiguration(url). Realms created this way are query-based Realms by default.
[ObjectServer] Added SyncUser.getDefaultConfiguration().
The Realm bytecode transformer now supports incremental builds (#3034).
Improved speed and allocations when parsing field descriptions in queries (#5547).

Bug Fixes

RealmQuery.in() now support null which will always return no matches (#4011).
Added support for RealmQuery.alwaysTrue() and RealmQuery.alwaysFalse().

Bug Fixes

Changing a primary key from being nullable to being required could result in objects being deleted (##5899).

5.0.1 (2018-04-09)

Enhancements

[ObjectServer] SyncConfiguration.automatic() will make use of the host port to work out the default Realm URL.
[ObjectServer] A role is now automatically created for each user with that user as its only member. This simplifies the common use case of restricting access to specific objects to a single user. This role can be accessed at PermissionUser.getRole().
[ObjectServer] Expose Role.getMembers() to access the list of associated UserPermission.

Bug Fixes

RealmList.move() did not move items correctly for unmanaged lists (#5860).
RealmObject.isValid() not correctly returns false if null is provided as an argument (#5865).

Added support for new data type MutableRealmIntegers. The new type behaves almost exactly as a reference to a Long (mutable nullable, etc) but supports increment and decrement methods, which implement a Conflict Free Replicated Data Type, whose value will converge even when changed across distributed devices with poor connections (#4266).
Added more detailed exception message for RealmMigrationNeeded.
Bumping schema version only without any actual schema changes will just succeed even when the migration block is not supplied. It threw an RealmMigrationNeededException before in the same case.
Throw IllegalStateException when schema validation fails because of wrong declaration of @LinkingObjects.

Bug Fixes

3.1.0 (2017-04-05)

Breaking Changes

Updated file format of Realm files. Existing Realm files will automatically be migrated to the new format when they are opened, but older versions of Realm cannot open these files.
[ObjectServer] Due to file format changes, Realm Object Server 1.3.0 or later is required.

Enhancements

Added support for reverse relationships through the @LinkingObjects annotation. See io.realm.annotations.LinkingObjects for documentation.
- This feature is in @Beta.
- Queries on linking objects do not work. Queries like where(...).equalTo("field.linkingObjects.id", 7).findAll() are not yet supported.
- Backlink verification is incomplete. Evil code can cause native crashes.
The listener on RealmObject will only be triggered if the object changes (#3894).
Added RealmObjectChangeListener interface that provide detailed information about RealmObject field changes.
Listeners on RealmList and RealmResults will be triggered immediately when the transaction is committed on the same thread (#4245).

Internal

Using the Object Store's Session and SyncManager.
Upgraded to Realm Sync 1.5.0.
Upgraded to Realm Core 2.5.1.
Upgraded Gradle to 3.4.1

3.0.0 (2017-02-28)

Breaking Changes

RealmResults.distinct() returns a new RealmResults object instead of filtering on the original object (#2947).
RealmResults is auto-updated continuously. Any transaction on the current thread which may have an impact on the order or elements of the RealmResults will change the RealmResults immediately instead of change it in the next event loop. The standard RealmResults.iterator() will continue to work as normal, which means that you can still delete or modify elements without impacting the iterator. The same is not true for simple for-loops. In some cases a simple for-loop will not work (https://realm.io/docs/java/3.0.0/api/io/realm/OrderedRealmCollection.html#loops), and you must use the new createSnapshot() method.
RealmChangeListener on RealmObject will now also be triggered when the object is deleted. Use RealmObject.isValid() to check this state(#3138).
RealmObject.asObservable() will now emit the object when it is deleted. Use RealmObject.isValid() to check this state (#3138).
Removed deprecated classes Logger and AndroidLogger (#4050).

Deprecated

RealmResults.removeChangeListeners(). Use RealmResults.removeAllChangeListeners() instead.
RealmObject.removeChangeListeners(). Use RealmObject.removeAllChangeListeners() instead.
RealmResults.distinct() and RealmResults.distinctAsync(). Use RealmQuery.distinct() and RealmQuery.distinctAsync() instead.

Enhancements

Added support for sorting by link's field (#672).
Added OrderedRealmCollectionSnapshot class and OrderedRealmCollection.createSnapshot() method. OrderedRealmCollectionSnapshot is useful when changing RealmResults or RealmList in simple loops.
Added OrderedRealmCollectionChangeListener interface for supporting fine-grained collection notifications.
Added support for ChangeListeners on RealmList.
Added RealmList.asObservable().

Bug Fixes

Element type checking in DynamicRealmObject#setList() (#4252).
Now throws IllegalStateException instead of process crash when any of thread confined methods in RealmQuery is called from wrong thread (#4228).
Now throws IllegalStateException when any of thread confined methods in DynamicRealmObject is called from wrong thread (#4258).

Internal

Use Object Store's Results as the backend for RealmResults (#3372).
- Use Object Store's notification mechanism to trigger listeners.
- Local commits triggers Realm global listener and RealmObject listener on current thread immediately instead of in the next event loop.

2.3.2 (2017-02-27)

RealmList.contains() and RealmResults.contains() now correctly use custom equals() method on Realm model classes.
Build error when the project is using Kotlin (#4087).
Bug causing classes to be replaced by classes already in Gradle's classpath (#3568).
NullPointerException when notifying a single object that it changed (#4086).

2.3.0 (2017-01-19)

Object Server API Changes

Realm Sync v1.0.0 has been released, and Realm Mobile Platform is no longer considered in beta.
Breaking change: Location of Realm files are now placed in getFilesDir()/<userIdentifier> instead of getFilesDir()/. This is done in order to support shared Realms among users, while each user retaining their own local copy.
Breaking change: SyncUser.all() now returns Map instead of List.
Breaking change: Added a default UserStore saving users in a Realm file (RealmFileUserStore).
Breaking change: Added multi-user support to UserStore. Added get(String) and remove(String), removed remove() and renamed get() to getCurrent().
Breaking change: Changed the order of arguments to SyncCredentials.custom() to match iOS: token, provider, userInfo.
Added support for PermissionOffer and PermissionOfferResponse to SyncUser.getManagementRealm().

2.2.2 (2017-01-16)

Object Server API Changes (In Beta)

Disabled Realm.compactRealm() when sync is enabled as it might corrupt the Realm (realm/realm-core#2345).

Bug fixes

"operation not permitted" issue when creating Realm file on some devices' external storage (#3629).
Crash on API 10 devices (#3726).
UnsatisfiedLinkError caused by pipe2 (#3945).
Unrecoverable error with message "Try again" when the notification fifo is full (#3964).
Realm migration wasn't triggered when the primary key definition was altered (#3966).
Use phantom reference to solve the finalize time out issue (#2496).

Enhancements

All major public classes are now non-final. This is mostly a compromise to support Mockito. All protected fields/methods are still not considered part of the public API and can change without notice (#3869).
All Realm instances share a single notification daemon thread.
Fixed Java lint warnings with generated proxy classes (#2929).

Internal

Upgraded Realm Core to 2.3.0.

Unexpected RealmMigrationNeededException was thrown when a field was added to synced Realm.

Enhancements

Added support for the annotationProcessor configuration provided by Android Gradle Plugin 2.2.0 or later. Realm plugin adds its annotation processor to the annotationProcessor configuration instead of apt configuration if it is available and the com.neenbedankt.android-apt plugin is not used. In Kotlin projects, kapt is used instead of the annotationProcessor configuration (#3026).

2.1.1 (2016-10-27)

Bug fixes

Fixed a bug in Realm.insert and Realm.insertOrUpdate methods causing a StackOverFlow when you try to insert a cyclic graph of objects between Realms (#3732).

Bug fixes

ProGuard configuration introduced in 2.1.0 unexpectedly kept classes that did not have the @KeepMember annotation (#3689).

2.1.0 (2016-10-25)

Breaking changes

- SecureUserStore has been moved to its own GitHub repository: https://github.com/realm/realm-android-user-store See https://github.com/realm/realm-android-user-store/blob/master/README.md for further info on how to include it.

Object Server API Changes (In Beta)

Permission error when a database file was located on external storage (#3140).
Memory leak when unsubscribing from a RealmResults/RealmObject RxJava Observable (#3552).

Enhancements

Realm.compactRealm() now works for encrypted Realms.
Added first(E defaultValue) and last(E defaultValue) methods to RealmList and RealmResult. These methods will return the provided object instead of throwing an IndexOutOfBoundsException if the list is empty.
Reduce transformer logger verbosity (#3608).
RealmLog.setLevel(int) for setting the log level across all loggers.

Internal

Upgraded Realm Core to 2.1.3

Credits

Thanks to Max Furman (@maxfurman) for adding support for first() and last() default values.

2.0.2 (2016-10-06)

This release is not protocol-compatible with previous versions of the Realm Mobile Platform. The base library is still fully compatible.

2.0.0 (2016-09-27)

This release introduces support for the Realm Mobile Platform! See https://realm.io/news/introducing-realm-mobile-platform/ for an overview of these great new features.

Breaking Changes

Files written by Realm 2.0 cannot be read by 1.x or earlier versions. Old files can still be opened.
It is now required to call Realm.init(Context) before calling any other Realm API.
Removed RealmConfiguration.Builder(Context), RealmConfiguration.Builder(Context, File) and RealmConfiguration.Builder(File) constructors.
isValid() now always returns true instead of false for unmanaged RealmObject and RealmList. This puts it in line with the behaviour of the Cocoa and .NET API's (#3101).
armeabi is not supported anymore.
Added new RealmFileException.
- IncompatibleLockFileException has been removed and replaced by RealmFileException with kind INCOMPATIBLE_LOCK_FILE.
- RealmIOExcpetion has been removed and replaced by RealmFileException.
RealmConfiguration.Builder.assetFile(Context, String) has been renamed to RealmConfiguration.Builder.assetFile(String).
Object with primary key is now required to define it when the object is created. This means that Realm.createObject(Class<E>) and DynamicRealm.createObject(String) now throws RealmException if they are used to create an object with a primary key field. Use Realm.createObject(Class<E>, Object) or DynamicRealm.createObject(String, Object) instead.
Importing from JSON without the primary key field defined in the JSON object now throws IllegalArgumentException.
Now Realm.beginTransaction(), Realm.executeTransaction() and Realm.waitForChange() throw RealmMigrationNeededException if a remote process introduces incompatible schema changes (#3409).
The primary key value of an object can no longer be changed after the object was created. Instead a new object must be created and all fields copied over.
Now Realm.createObject(Class) and Realm.createObject(Class,Object) take the values from the model's fields and default constructor. Creating objects through the DynamicRealm does not use these values (#777).
When Realm.create*FromJson()s create a new RealmObject, now they take the default values defined by the field itself and its default constructor for those fields that are not defined in the JSON object.

Enhancements

Added realmObject.isManaged(), RealmObject.isManaged(obj) and RealmCollection.isManaged() (#3101).
Added RealmConfiguration.Builder.directory(File).
RealmLog has been moved to the public API. It is now possible to control which events Realm emit to Logcat. See the RealmLog class for more details.
Typed RealmObjects can now continue to access their fields properly even though the schema was changed while the Realm was open (#3409).
A RealmMigrationNeededException will be thrown with a cause to show the detailed message when a migration is needed and the migration block is not in the RealmConfiguration.

Bug fixes

Fixed a lint error in proxy classes when the 'minSdkVersion' of user's project is smaller than 11 (#3356).

Enhancements

Added RealmQuery.in() for a comparison against multiple values.
Added byte array (byte[]) support to RealmQuery's equalTo and notEqualTo methods.
Optimized internal caching of schema classes (#3315).
