0.3.0

• Added support for custom queries.
• Added API for retrieving the list of languages supported by the database. These can subsequently be used in both built-in and custom queries.
• Added API for retrieving library and file format versions.

0.2.1

• Removed 'build' constraint from ppx dependencies.

0.2.0

• Introduced a separate exception type thrown by the library when an internal error occurs.

• Simplified error type returned by data lookup functions:

  • Removed Invalid_node_number and Invalid_lookup_path error variants since it should not be possible to provoke these errors through the high-level interface provided by this library. An exception will be thrown instead if these errors are encountered.
  • Removed the Lookup_path_does_not_match_data error variant since it simply indicates that a piece of information is not present in the database. The lookup functions will now return Ok None instead of Error _ if the corresponding error code is returned by libmaxminddb.

0.1.0

• Initial release
