Hi
I'm an Unity Developer
Recently my project Upgrade MsgPack from 1.8.9 to 3.1.4, and everything is OK
except my game's saver data would be decoded by Node.Js's Messagepack Library
and it's not shown as a two-dimensional array anymore

before Upgrade：

after Upgrade：

I want to know that is there any possible to keep the old data format?
or what library should i use to decode new format for Node.js?
