3.1.1

• When handling a deserialization exception, the decoder now avoids
  throwing a NullPointerException when one of the constructor arguments
  is null. Reported by Keith Massey. GitHub #164.

3.1.0

• Reader supports iterating over the whole database or within a network.

3.0.0

• Java 11 or greater is now required.
• This library is now a Java module.

2.1.0

• Messages for DeserializationException have been improved, and the cause
  is included, if any. Moreover, the message provides detail about the involved
  types, if the exception is caused by an IllegalArgumentException.

2.0.0

• No changes since 2.0.0-rc2.

2.0.0-rc2

• Build using the --release command-line option so linking when using
  Java 8 works.

2.0.0-rc1

• Significant API changes. The get() and getRecord() methods now take a
  class parameter specifying the type of object to deserialize into. You
  can either deserialize into a Map or to model classes that use the
  MaxMindDbConstructor and MaxMindDbParameter annotations to identify
  the constructors and parameters to deserialize into.
• jackson-databind is no longer a dependency.
• The Record class is now named DatabaseRecord. This is to avoid a
  conflict with java.lang.Record in Java 14.

1.4.0

• IMPORTANT: Java 8 is now required. If you need Java 7 support, please
  continue using 1.3.1 or earlier.
• The decoder will now throw an InvalidDatabaseException on an invalid
  control byte in the data section rather than an
  ArrayIndexOutOfBoundsException. Reported by Edwin Delgado H. GitHub
  #68.
• In order to improve performance when lookups are done from multiple
  threads, a use of synchronized has been removed. GitHub #65 & #69.
• jackson-databind has been upgraded to 2.11.0.

1.3.1

• Correctly decode strings that are between 157 and 288 bytes long. 1.3.0
  introduced a regression when decoding these due to using a signed byte
  as an unsigned value. Reported by Dongmin Yu. GitHub #181 in
  maxmind/GeoIP2-java.
• Update jackson-databind dependency.

1.3.0

• IMPORTANT: Java 7 is now required. If you need Java 6 support, please
  continue using 1.2.2 or earlier.
• The method getRecord was added to com.maxmind.db.Reader. This method
  returns a com.maxmind.db.Record object that includes the data for the
  record as well as the network associated with the record.
