Artifact 4bd030691a0540c7bb4ca0e83d8250183583884b65b8eda6a74c7a601b9b6cd8:

• File src/OFMutableDictionary.m — part of check-in [6ce0093f8d] at 2023-04-10 19:22:32 on branch trunk — Remove OFSerialization

  While the idea sounds nice that the tag name is the class, this means the
  serialization includes whether something is mutable or immutable. This means
  doing as much as making something immutable changes the serialization, which
  can then cause issues after being deserialized. (user: js, size: 4379) [annotate] [blame] [check-ins using] [more...]
