[Hawkular-dev] Hawkular Inventory 0.20.0.Final released

Hi all, I'm proud to announce that Hawkular Inventory 0.20.0.Final has been released. Apart from an updated version of Sqlg and slightly reduced distribution size, the *big* new feature this version brings is the support for keeping history of changes to inventory. From now on, you are able to retrieve the history of updates made to an entity, but you can also "look at" an entity, or whole inventory, as it looked at certain point in time - questions like "what DB was this application connected to last month?", "What was the list of feeds reporting on our production environment in March", etc. All that possible using a single new query parameter to the REST endpoints - "?at=<TIMESTAMP>". 0.20.0.Final doesn't offer the ability to compact or delete the "old" data from inventory (delete now merely marks the entity in question as deleted from the specified time onward) - that will be the focus of our very next release. We wanted to let this release out though so that people can start enjoying the nostalgic views at the good old days of their inventory ;) Special thanks go out to Joel Takvorian for reviews, fixes and the work in upstream Sqlg. Thanks, -- Lukas Krejci
