I've copied this from the Logstash mailing list;
I am pleased to announce that The Logstash Book has been updated to
reflect the 1.5.0 release of Logstash. There are updates to
installation, configuration, Kibana and plugin development in the new
version.
It also includes a bunch of updates from awesome folks who have
submitted errata and pointed out issues. Please keep this up - it really
helps me!
You can find a full list of the changes and updates:
If you've previously bought the book then this update is totally free
(if your download link has expired just email me and I'll renew it).
You can also purchase the book from the website. Or on Kindle from Amazon.
Please continue to send me feedback, reviews and errata as it is very
much appreciated!
Kind Regards
James Turnbull
