It doesn't change so often, but just has seen its 10th release. Actually, it was the first release in more than three years. But, fortunately, core chemical facts do not change often, nor much. So, this release has a number of data fixes, a few recent experimental isotope measurements, and also includes the new official names of the livermorium and flerovium elements. There is a full overview of changes.
BODR 10 is brought to you by Jean Brefort, Daniel Leidert, and I did some small bits too. Also big thanks to all project that keep using BODR and contribute by providing high quality feedback reports!
Oh, and if you use BODR isotope or element data, you are kindly invited to cite the one of the Blue Obelisk papers.
