[Hawkular-dev] Hawkular Inventory 0.20.0.Final released

[Lukas Krejci]

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,
