[[logstash-6-0-0-alpha1]]
=== Logstash 6.0.0-alpha1 Release Notes
* Introducing a new internal representation for the existing Logstash configuration that forms the
foundation of many new features. This is not a breaking change, and existing configs will work as is.

== General
* {lsissue}2376[Issue 2376]: Added ability to install and upgrade Logstash plugins without requiring internet
connectivity.
* {lsissue}3576[Issue 3576]: Support alternate or private Ruby gems server to install and update plugins.
* {lsissue}3451[Issue 3451]: Added ability to reliably shutdown Logstash when there is a stall in event processing. This
option can be enabled by passing `--allow-unsafe-shutdown` flag while starting Logstash. Please be aware that any in-
flight events will be lost when shutdown happens.
* {lsissue}4222[Issue 4222]: Fixed a memory leak which could be triggered when events having a date were serialized to
string.
* Added JDBC input to default package.
* {lsissue}3243[Issue 3243]: Adding `--debug` to `--configtest` now shows the configuration in blocks annotated by source
config file. Very useful when using multiple config files in a directory.
* {lsissue}4130[Issue 4130]: Reset default worker threads to 1 when using non thread-safe filters like multiline.
* Fixed file permissions for the `logrotate` configuration file.
* {lsissue}3861[Issue 3861]: Changed the default heap size from 500MB to 1GB.
* {lsissue}3645[Issue 3645]: Fixed config check option when starting Logstash through init scripts.

=== Twitter

sample Twitter streaming endpoint.
* https://github.com/logstash-plugins/logstash-input-twitter/issues/22[Issue 22]: Added hashtags, symbols and
user_mentions as data for the non extended tweet event.
* https://github.com/logstash-plugins/logstash-input-twitter/issues/20[Issue 20]: Added an option to filter per location
and language.
* https://github.com/logstash-plugins/logstash-input-twitter/issues/11[Issue 11]: Added an option to stream data from a
list of users.

=== Beats
* https://github.com/logstash-plugins/logstash-input-beats/issues/10[Issue 10]: Properly handle multiline events from
multiple sources, originating from Filebeat.
[float]
=== File
* https://github.com/logstash-plugins/logstash-input-file/issues/44[Issue 44]: Properly handle multiline events from
multiple sources.
[float]
=== Eventlog
* https://github.com/logstash-plugins/logstash-input-eventlog/issues/11[Issue 11]: Change the underlying library to
capture Event Logs from Windows more reliably.
[float]
== Output
[float]
=== Elasticsearch
* Improved the default template to use doc_values wherever possible.
* Improved the default template to disable fielddata on analyzed string fields.
* https://github.com/logstash-plugins/logstash-output-elasticsearch/issues/260[Issue 260]: Added New setting: timeout.
This lets you control the behavior of a slow/stuck request to Elasticsearch that could be, for example, caused by network,
firewall, or load balancer issues.
*`GeoIP`*: You can now use MaxMind's commercial database to get enriched Geo information. ASN data can be
obtained via the GeoIP2-ISP database.
