Ruby

• Dropped Ruby 2.3 and 2.4 support for CI and releases. (#9311)
• Added Ruby 3.1 support for CI and releases (#9566).

• Suppress warning for intentional circular require (#9556)
• JSON will now output shorter strings for double and float fields when possible without losing precision.
• Encoding and decoding of binary format will now work properly on big-endian systems.
• UTF-8 verification was fixed to properly reject surrogate code points.
• Unknown enums for proto2 protos now properly implement proto2's behavior of putting such values in unknown fields.

Java

• Revert "Standardize on Array copyOf" (#9400)
• Resolve more java field accessor name conflicts (#8198)
• Don't support map fields in DynamicMessage.Builder.{getFieldBuilder,getRepeatedFieldBuilder}
• Fix parseFrom to only throw InvalidProtocolBufferException
• InvalidProtocolBufferException now allows arbitrary wrapped Exception types.
• Fix bug in FieldSet.Builder.mergeFrom
