Input Plugins

file: * Issue 81: Adds the close_older configuration option to close files that remain unmodified for longer than the specified timespan in seconds. * Issue 81: Adds the ignore_older configuration option to ignore the contents of files that have remained unmodified for longer than the specified timespan in seconds.

'jdbc`: * Issue 57: Allows tracking by a column value rather than by last run time. This is a breaking change, as users may be required to change from using sql_last_start to use sql_last_value in their queries. Time-based queries require no other changes. * Issue 44: Adds an option to control lowercasing of column names.

beats: * Issue 14: Refactored beats input to fix thread synchronization issues under high data volume.

kafka: * Issue 59: Fixes a CPU load issue when no new messages are available in the Kafka broker.

http: * Issue 33: Adds support for compressed and gzip POST requests.

multiline: This filter is now deprecated. Use the multiline codec plugin instead.

date: * Issue 23: The timezone setting now supports the sprintf format. * Issue 33: Improves handling for new year rollovers when the year is not present in the time format. When the local timestamp is December and the event time is January, the year is set to the following year. When the local time is January and the event time is December, the year is set to the previous year.

Output Plugins

elasticsearch: * Issue 4433: Node protocol is now discouraged and will not be actively maintained. Use the http or transport protocols instead. * Issue 235: Adds scripted update support. * Issue 321: Changes retry behavior.
