FreeBSD 11.0 was not released yesterday. It was expected that October 5, 2016 would be the date but a new date is now set. The FreeBSD team has delayed the release of FreeBSD 11.0 to October 10, 2016. The reason via the FreeBSD mailing list:
As many of you are aware, 11.0-RELEASE needed to be rebuilt to address
several issues that were discovered after the release was built. Extra
caution is being taken in testing the rebuilt releases, so at present,
the final release announcement is planned for Monday, October 10.Thank you for your patience in waiting for 11.0-RELEASE.
