New release 1.0.15

Hi guys, we have a new release. What is new? o FreeBSD and NetBSD port renewed. OpenBSD port introduced. o import/preimport 'show route' modifiers was renamed to export/preexport for consistency with filters. o Minor change in the grammar of 'interface' config option. o Many bugfixes in IPv6 BGP. o As usual, miscellaneous bugfixes. There is an issue with BGP MD5 authentication on BSD system. The password has to be set by external utility. We will work on it in some next release. However BSD is port is working again and you can use BGP MD5 authentication. Ondrej
