new version FRED-2.29

Hi, we have published FRED version 2.29. During several previous releases we have rewritten almost all code responsible for EPP communication with registrars. This refactoring was necessery for implementation of new features in the future. Here is a compilation of some significant changes. - support for more operating systems. For the first time we provide also packages for latest RHEL/Centos version 7. Since Ubuntu 12.04 will lost its long term support in April, we will not provide packages for this version anymore. Preffered version of Ubuntu is 16.04. We use Ubuntu 16.04 in production for some time without any issues. This also means that Ubuntu 16.04 is most tested platform. In other platforms we only run limited set of automated tests so registries are required to do more indepth tests themselves.  - configurable domain name format checking. Checking of validity of domain name is configurable per zone via linking to set of preconfigured checkers in database table zone_domain_name_validation_checker_map. - new idn support configuration. There used to be allow_idn option in server configuration file that meant that regular registrars are able to register domains in xn-- format (idn domains) in all zones. In current version it is possible to configure idn support per zone via mechanism mentioned earlier. Support for idn is just another preconfigured checker. - configurable dnssec algorithm checking. Until now, there was no checking of dnssec algorithm number used in EPP create_keyset or update_keyset EPP commands. If registries would like to limit this check only for some algorithms, they can do that via modification of database tables dnssec_algorithm and dnssec_algorithm_blacklist. - configurable limit of minimal number of nameservers in nsset. Until now, there was hardcoded requirement to have at least 2 nameservers and maximum 10 nameservers in nsset. Since this was limitation for some registries that wanted to use FRED, we moved this limit into configuration option nsset_min_hosts and nsset_max_hosts in server configuration file - asynchronous notification about EPP events. Notifications for domain state change has always been generated asynchronously via fred-admin commands, but notifications about EPP events done by registrars were created as part of EPP operation. To speed up system a little bit and to be able to continue EPP operation even when notification system is down, we made also notification about EPP events asynchronnous. So don't forget to add into cron system command 'fred-admin -- notify_email_objects_events' in intervals of your preference if you want to keep sending notifications. Regards, Jaromir
