Use flattened JSON in output

The format-flat-json template function is identical to the format-json template function, but nested JSON objects are flattened in the output. For details, see "Template functions of syslog-ng OSE" in the Administration Guide.

Modify timezone using rewrite rules

You can set, fix, or guess the timezone of messages using timezone-specific rewrite rules. For details, see "Rewrite the timezone of a message" in the Administration Guide.

Wildcards in add-contextual-data()

You can now use shell-style globbing (wildcards) in the selector of add-contextual-data() databases. For details, see "Shell-style globbing in the selector" in the Administration Guide.

Server Name Identification (SNI) support

You can now send Server Name Identification (SNI) information when using transport(tls) by enabling the sni(yes) option. For details, see "TLS options" in the Administration Guide.
