This is the list of user-facing changes for Mirabelle.

v0.9.0

Fix a bug in the mirabelle graphviz command.

Removal of the “disk queue” feature: I was not happy about it
mirabelle graphviz subcommand to generate graphical representations of streams
Add the stream name in all actions logging events
Basic auth support for the HTTP server

Add /health endpoint. Both /health and /healthz return the same thing.
Improve websocket error messages on bad queries.
Improve error messages in test mode.
Add the ability to persist on the file system streams created through the API. It can be enabled by setting persist to true in the stream configuration.
Add coll-where action. This action can be used to filter a list of events based on a condition.
Add coll-sort action, which can be used to sort a collection of events based on a field.
Add moving-time-window action. This window always return the events which arrived the last duration seconds.
Add ssort action. This action buffers events for some time and send them one by one sorted to downstream actions. It can be a nice way to tolerate some late events in streams.
Allow nesting :or add and values in conditions. For example [:and [:or [:= :service "foo"] [:= :service "bar"]] [:> :metric 1]] is now a value condition.

Elasticsearch I/O
Force the use of the #secret reader for sensitive information in I/O
throttle: add a second parameter to specify the number of events to keep
use aero to load the configuration and support aero profiles
include action, which can be used to reuse part of configurations in streams
Improve error messages
Add a new :native? parameter to the TCP server to enable epoll/kqueue on Netty.

Mirabelle now build one index per stream.
All actions reinjecting events into streams (reaper, reinject!) now reinject events by default on the current stream
reaper action: add a mandatory “interval” parameter to expire events.

First release ;)
