My goal with this is to keep a collection of posts to refer to at a later time for development related to all of Hive. This will be focused more towards developers, and so tutorials and such will make it in, but since it's not a update log for all projects, only core updates will make it in(after they have been to a point where it's added into the codebase or its decided that it will be added to the codebase and someone has to write it up). I'll try and separate this out by major hive projects if possible.
CORE
Core refers to the core of Hive, which is hived, and hivemind.

Hive-Engine
Hive-Engine is a layer 2 addition to hive to add in some custom tokens as well as NFTs and other things that are not on Hive. It uses hives custom_json feature to run.
