0.7.0

Released on 2017.02.19

Added

  • Missing nullability annotations and light-weight generics throughout code base
  • New playground content

Updated

  • Project for Xcode 8
  • Swift tests for Swift 3
  • Playground contents and syntax for Swift 3
  • Travis config for iOS 10.2, macOS 10.12
  • Deployment targets to macOS 10.10, iOS 9.0

Removed

Breaking Changes

The built-in encoding/decoding of keys and values via the encoding options is completelty removed from this release. The API is completely NSData-based now.

  • Removed built-it Key/Value Encoders and Decoders
    • The conversions of custom types to/from NSData is the responsibility of the caller
  • Removed EncodingOptions
  • Removed all methods depending on EncodingOptions and the built-in key/value encoding and all of the their variants:
    • setObject:forKey:
    • deleteObjectForKey:
    • objectForKey:
    • mergeObject:forKey:
    • mergeOperation:forKey:
  • Refactored all Iterator, Key Comparator and Merge Operator methods accordingly
  • Removed NSNumber Key-Comparators
  • Rename method for setting up default read & write options from setDefaultReadOptions:andWriteOptions: to setDefaultReadOptions:writeOptions:
    • The custom Swift equivalent is setDefault(readOptions:writeOptions:)

0.6.0

Released on 2016.06.12

Hotfix

  • Removed Cocoapods badges from README

0.6.0

Released on 2016.06.12

Added

  • Support for opening the database in read-only mode
  • Support for Write Batch with Index and Write Batch Iterator
  • Support for Range Compaction operations
  • Nullability annotations
    • Better compatibility with Swift
  • New statistics and counters
  • Cocoapods Podspec
  • Travis integration

Breaking Changes

  • RocksDB initializers were changed to class instead of instance methods
  • Removed RocksDB methods without error parameter
    • Better compatibility with Swift's error-handling model
  • Refactored all RocksDB methods so that the error parameter is the last
    • Better compatibility with Swift's error-handling model
  • Removed Column Family Metadata from iOS target
  • RocksDBIteratorKeyRange is refactored to RocksDBKeyRange
    • Key ranges are used not only for iterations but also for compaction jobs
    • Empty-range constant is refactored to open-range, since it represents a range containing all the keys
  • ObjectiveRocks builds frameworks now instead of static libraries
