Subject [ANNOUNCE] Apache Metron release 0.7.1
Date Wed, 15 May 2019 21:48:36 GMT
Hi all,

I’m pleased to announce the release of Metron 0.7.1! There's been a lot of
work in put in for everything including fixes, improvements, documentation,
refactoring, and discussion. Thanks to everyone who's contributed, and
thanks to our users!

There is a callout for users regarding the development environment, and the
use of parser aggregation by default. This functionality is used by default
in the environment to fit more sensors into the limited resources, but
management of this feature is not yet available in the management UI. How
to work with and disable it as needed, are detailed in
and Parser
Aggregation Feature
