Hi everyone, I wanted to notify everyone here that on yt-dev I have sent a message proposing a change in license for yt, from the current copyleft GPLv3 to a permissive, non-copyleft open source license like the BSD license, used by most other packages in the open source scientific software community. I've laid out motivations for this as well as the implementation method, if it is decided on. If this change is made, it will *not* change yt's status as open source, freely available, and community-developed. If anything, I have started this discussion in an effort to help ensure the health of yt in the ecosystem of open source scientific software. Here is the email: http://lists.spacepope.org/pipermail/yt-dev-spacepope.org/2013-July/003239.h... If you would like to participate, I would encourage you to subscribe to yt-dev and participate there. If there is broad community consensus, everyone who has contributed a patch or changeset to yt will receive an email from me asking for consent to change the license. Best wishes, Matt
