Dear Materials Project users,
The MP team has made some changes on our backend so as to enable a lot of additional data (the site now has 20% more materials than an hour ago!) and greater ease extending our data sets going forward. Because we’ve changed a lot, there are bound to be bugs that we simply missed in our extensive testing. We would like you to find these and post them publicly so that we can fix them and the community can hold us to the high standard we all want out of this project.
