- MaxMind::DB::Writer::Tree->new now accepts a merge_strategy parameter. When
  merge_record_collisions is set, the default merge strategy is "toplevel",
  which only merges the top level of the record hash. A new "recurse" merge
  strategy has been added, which recursively merged the records data
  structure, including both arrays and hashes. Please see the documentation
  for more details.

- The documentation incorrectly stated the the MaxMind::DB::Writer::Tree->new
  parameter "map_key_type_callback" was optional. It is actually required.

- $tree->insert_network now takes an optional additional-arguments hash
  reference parameter. If this hash contains a truthy value for the
  force_overwrite key, any data for the network will be overwritten even when
  merge_record_collisions is enabled.

- Previously two equivalent data structures added to a database could end up
  with different keys, causing both to be added to the final file separately.
  The key generation was updated to reduce the likelihood of this happening.


0.100003 2015-06-04

- Fixed a bug in the data thawing code that incorrectly incremented the
  SV referencing the HV rather than the HV. This could cause warnings about
  attempts to free an unreferenced SV.
- Fixed memory leaks on merge failures.
- Minor code cleanups.

- Fixed test suite on OS X: Altered to cope with different Net::Works network
  rendering on OS X


0.100001 2015-03-12

- Updated to the latest versions of the Math::Int128 (0.21) and Math::Int64
  (0.51) C API integration code, as well as depending on the newest version of
  the module from Perl.


0.080000 2015-03-04

- Implemented $tree->freeze_tree and
  MaxMind::DB::Writer::Tree->new_from_frozen_tree methods. This provides a way
  of passing the tree between different processes.

- Made the attribute reader methods for all values passed to the constructor
  public.

- Added some docs on how insert order affects overlapping networks. GitHub
  #18.

- Fixed memory leaks when adding data to the tree.

- Reduced the size of various structs used in the C code to reduce memory
  usage.

- The map_key_type_callback argument for the MaxMind::DB::Writer::Tree class
  is now required. In some use cases it's not really used but in the most
  common use case leaving it out simply leads to confusing errors when
  attempting to write the tree to disk. GH #10.


0.050007 2014-10-20

- The writer now iterates over the search tree in depth-first order when the
  MaxMind::DB::Writer::Tree->iterate method is called. This means that
  networks are seen in IP address order.


0.050006 2014-07-28

- The writer now throw an error when writing out the database if it would try
  to write a record value in the search tree that is larger than the search
  tree can handle. For example, if your record size is 24 bits, you cannot
  write a value larger than (2^24)-1. Fixed by Greg Oschwald.

- The Build.PL file shipped with this distro now dies if you try to run it on
  Windows, since this module simply doesn't work on Windows.


0.050005 2014-07-03

- The merge-on-collision feature was fairly broken. Fixed by Greg Oschwald.
