Prepare release 5.3.0-preview2

Update Android version to 5.2.1-preview1

Sync

• New Sync protocol V8: using new clients also requires a server update
• SyncClient: add a constructor, deprecate Sync.client and related helper methods.
• SyncClient: add constructor parameters to provide custom certificates and configuration flags.
  • Remove-operations with object content for Sync filters (optional setting; sync flag)
  • Add DebugLogTxLogs sync flag to log TX log processing on the client side
  • Add SkipInvalidTxOps sync flag to skip invalid operations in a TX log on the client side; errors
    are logged and the TX is only partially applied.
• Remove superfluous sync listener triggers when sync filters "report updates" (SKIP_TX)
• Sync clients compress earlier: reduces disk storage for outgoing data
• Reworked certificates for Apple platforms
• Removed support for older Sync protocol versions before 2024-09; protocol V5+ is now required.

• Added flex properties that can hold any kind of data ("schema-less") supporting the following types on the Dart side:
  • Maps: JSON-like data structure with string keys and arbitrary values, including nested maps and lists.
  • Lists: can hold elements of any type, even mixed (like JSON arrays).
    On the Dart side, ObjectBox also offers binding to a list of maps, e.g. List<Map<String, dynamic>>.
  • Dynamic/Object: can hold any kind of data, including primitive types like integer, floating point and string,
    plus maps and lists.
  • Sync note: when used together with the MongoDB Connector,
    flex properties allow storing nested documents from MongoDB.
• Added dateUtc and dateUtcNano property types for DateTime read back UTC.
  #308
• Added "GeneratorVersion" enum to enforce generated code is compatible with the runtime library.
  You must run dart run build_runner build after updating the objectbox package.
  Until you regenerate code, compiling will fail with a message like this:
  "Error: Required named parameter 'generatorVersion' must be provided".

• Update ObjectBox database for Flutter iOS/macOS apps to 5.1.1.
  For existing projects, run pod repo update and pod update ObjectBox in the ios or macos directories.
  • Sync client: fix for encrypted (wss://) connections on iOS devices.

• Update ObjectBox database for Flutter Linux/Windows, Dart Native apps to 5.0.0.
• Update ObjectBox database for Flutter iOS/macOS apps to 5.1.0.

  For existing projects, run pod repo update and pod update ObjectBox in the ios or macos directories.

• macOS: throw an error if the macosApplicationGroup parameter when opening a Store is too long (or empty). #515

Sync
