Thanks to the amazingly hard work of Bahamut Dragon, Wemes, Quonic, NGuill, & Andrew “Legacyking” Maitland who created the base 5e dataset and donated it to the project and Andrew Maitland who worked it over since the release to make sure it matches the SRD. PCGen has our first version of the D&D 5e Gamemode and dataset available for the public!
In case you somehow missed the news WotC released D&D 5th Edition as OGL and released an SRD yesterday.
Please note that this is our first version so please report any bugs and issues at http://jira.pcgen.org
UPDATE: This is now rolled into the latest production version of PCGen.
