6.2.7

  • Fix: when decoding in an ecs_compatibility mode, timestamp-normalized fields now handle provided-but-empty values #102

6.2.6

  • Fix: when decoding, escaped newlines and carriage returns in extension values are now correctly decoded into literal newlines and carriage returns respectively #98
  • Fix: when decoding, non-CEF payloads are identified and intercepted to prevent data-loss and corruption. They now cause a descriptive log message to be emitted, and are emitted as their own _cefparsefailure-tagged event containing the original bytes in its message field #99
  • Fix: when decoding while configured with a delimiter, flushing this codec now correctly consumes the remainder of its internal buffer. This resolves an issue where bytes that are written without a trailing delimiter could be lost #100

6.2.5

  • [DOC] Update link to CEF implementation guide #97

6.2.4

  • [DOC] Emphasize importance of delimiter setting for byte stream inputs #95

6.2.3

  • Feat: event_factory support #94

6.2.2

  • Fixed invalid Field Reference that could occur when ECS mode was enabled and the CEF field fileHash was parsed.
  • Added expanded mapping for numbered deviceCustom* and deviceCustom*Label fields so that all now include numbers 1 through 15. #89.

6.2.1

  • Added field mapping to docs.
  • Fixed ECS mapping of deviceMacAddress field. #88.

6.2.0

  • Introduce ECS Compatibility mode #83.

6.1.2

  • Added error log with full payload when something bad happens in decoding a message #84

6.1.1

  • Improved encoding performance, especially when encoding many extension fields #81

6.1.0

  • Fixed CEF short to long name translation for ahost/agentHostName field, according to documentation #75

6.0.1

  • Fixed support for deep dot notation #73

6.0.0

  • Removed obsolete sev and deprecated_v1_fields fields

5.0.7

  • Fixed minor doc inconsistencies (added reverse_mapping to options table, moved it to alpha order in option descriptions, fixed typo) #60

5.0.6

  • Added reverse_mapping option, which can be used to make encoder compliant to spec #51

5.0.5

  • Fix handling of malformed inputs that have illegal unescaped-equals characters in extension field values (restores behaviour from <= v5.0.3 in some edge-cases) (#56)

5.0.4

  • Fix bug in parsing headers where certain legal escape sequences could cause non-escaped pipe characters to be ignored.
  • Fix bug in parsing extension values where a legal unescaped space in a field's value could be interpreted as a field separator (#54)
  • Add explicit handling for extension key names that use array-like syntax that isn't legal with the strict-mode field-reference parser (e.g., fieldname[0] becomes [fieldname][0]).

5.0.3

  • Fix handling of higher-plane UTF-8 characters in message body

5.0.2

  • Update gemspec summary

5.0.1

  • Fix some documentation issues

5.0.0

  • move sev and deprecated_v1_fields fields from deprecated to obsolete

4.1.2

  • added mapping for outcome = eventOutcome from CEF whitepaper (ref:p26/39)

4.1.1

  • changed rt from receiptTime to deviceReceiptTime (ref:p27/39)
  • changed tokenizer to include additional fields (ad.fieldname)

4.1.0

  • Add delimiter setting. This allows the decoder to be used with inputs like the TCP input where event delimiters are used.

4.0.0

  • Implements the dictionary translation for abbreviated CEF field names from chapter Chapter 2: ArcSight Extension Dictionary page 3 of 39 CEF specification.
  • add _cefparsefailure tag on failed decode

3.0.0

  • breaking: Updated plugin to use new Java Event APIs

2.1.3

  • Switch in-place sub! to sub when extracting cef_version. new Logstash Java Event does not support in-place String changes.

2.1.2

  • Depend on logstash-core-plugin-api instead of logstash-core, removing the need to mass update plugins on major releases of logstash

2.1.1

  • New dependency requirements for logstash-core for the 5.0 release

2.1.0

  • Implements encode with escaping according to the CEF specification.
  • Config option sev is deprecated, use severity instead.

2.0.0

  • Plugins were updated to follow the new shutdown semantic, this mainly allows Logstash to instruct input plugins to terminate gracefully, instead of using Thread.raise on the plugins' threads. Ref: elastic/logstash#3895
  • Dependency on logstash-core update to 2.0
