The former is where the log administrator publishes + the (generated) global config file and the latter can be found in + that file. + +- The configuration setting 'publicaddresses', used by frontend nodes, + has changed to 'ctapiaddresses'. + +- The configuration setting 'known_roots' in merge configuration files + has changed to 'knownroots' to match what's being used by all other + nodes types. + + It should be noted that regeneration of Erlang config files is + necessary when upgrading to 0.10.0 from a previous version. + + This is indeed recommended for every release, and even recommended + to be done before restarting of nodes, in order to take advantage of + the new config management system. + +## Features + +- A new database backend, permdb, has been added. This is the + recommended backend. + +- Support for managing log configuration and log keys has been + added. Most notably, the log API keys have moved into the global + configuration file and a new logadmin key is used by the log owner + to sign that file. Node operators should regularly download the + global config, verify it and use it together with local config to + generate the Erlang config files used by the system (closes + CATLFISH-77). + +- Many configuration options can now be reloaded without restarting + a node (closes CATLFISH-32). + +## Improvements + +- Most of the merge process has been parallelised. It's now possible + to add both new frontend nodes and new secondary merge nodes to a + running log without risking long delays in publishing of new STH's + (closes CATLFISH-88). + +- Tooling both for initiating a log instance and for promoting a + secondary merge node to primary in an existing log instance has been + added. + +- The tests now do a better job at testing the merge failover case. + # Changes in catlfish 0.9.0 - 2016-12-04 ## Features |
