The minimum version of Realm Object Server has been increased to 3.21.0 and attempting to connect to older versions will produce protocol mismatch errors. Realm Cloud has already been upgraded to this version, and users using that do not need to worry about this.

Enhancements

  • Add createdAt, updatedAt, expiresAt and timeToLive properties to RLMSyncSubscription/SyncSubscription. These properties will be nil for subscriptions created with older versions of Realm, but will be automatically populated for newly-created subscriptions.
  • Add support for transient subscriptions by setting the timeToLive when creating the subscription. The next time a subscription is created or updated after that time has elapsed the subscription will be automatically removed.
  • Add support for updating existing subscriptions with a new query or limit. This is done by passing update: true (in swift) or setting options.overwriteExisting = YES (in obj-c) when creating the subscription, which will make it update the existing subscription with the same name rather than failing if one already exists with that name.
  • Add an option to include the objects from RLMLinkingObjects/LinkingObjects properties in sync subscriptions, similarly to how RLMArray/List automatically pull in the contained objects.
  • Improve query performance for chains of OR conditions (or an IN condition) on an unindexed integer or string property. (Core PR #2888 and Core PR #3250).
  • Improve query performance for equality conditions on indexed integer properties. (Core PR #3272).
  • Adjust the file allocation algorithm to reduce fragmentation caused by large numbers of small blocks.
  • Improve file allocator logic to reduce fragmentation and improve commit performance after many writes. (Core PR #3278).

Fixed

  • Making a query that compares two integer properties could cause a segmentation fault on x86 (i.e. macOS only). (Core PR #3253).
  • The downloadable_bytes parameter passed to sync progress callbacks reported a value which correlated to the amount of data left to download, but not actually the number of bytes which would be downloaded.

Compatibility

  • File format: Generates Realms with format v9 (Reads and upgrades all previous formats)
  • Realm Object Server: 3.21.0 or later.
  • Carthage release for Swift is built with Xcode 10.2.1.
