IMP 2.6.2 is now available. This corrects a few minor bugs and documentation issues in the previous release (2.6.1). In particular, we now provide packages for Ubuntu 16.04 (Xenial Xerus) and include a workaround for the buggy version of SWIG (3.0.8) included in that distribution.
See https://integrativemodeling.org/2.6.2/doc/manual/changelog.html for the full change log.
