The SBML editors are happy to announce that a release candidate specification for FBC version 3 is now available for public discussion at:
We welcome all comments on this spec; either reply here or open an issue at
We regret that while we normally try to make release candidates available for two weeks before finalization, we are under a deadline to publish in this year's JIB at the end of next week, so please submit any comments as soon as possible.
Special thanks to Brett Olivier and the other authors of the FBC specification for their efforts in getting this to its current form.
