Main changes are twofold.
First, all data besides Arduino sketch changed the license it is distributed under as below.
(before) Creative Commons 4.0 Attribution-ShareAlike
(after) Creative Commons 4.0 Attribution-NonCommercial-ShareAlike
This change will impose obligation to sign an additional contract on any entity who want to use data commercially. For non-commercial purposes, entities can use the data without permission from exiii Inc.. But in this case, the deliverables have to be shared alike under the same license (i.e. CC4.0 BY-NC-SA). The intent of this change is to have a portion of profit back to exiii Inc. as to sustain HACKberry project.
Secondly, the copyright of contents (e.g. pictures) and data posted on the github page or web forum managed by exiii Inc. will be assigned and transferred to exiii Inc.. This is to integrate progresses derived from contributors efficiently, and to introduce contents on other media of exiii Inc. so as to keep community active. However, it is not contributor’s obligation to post on github page or forum.
