1.18.0

Added

• mar.mar_entry_max_count, which allows for setting the max number of MAR
  entries in your tmp directory. This will default to 1000.
• logs.max_buffered_lines, which sets the max number of lines that will be
  kept in memory before lines are dropped. Note that this is the same as
  fluent-bit.max_buffered_lines, but will apply to both the fluent-bit log
  source as well as the journald log source. If you have previously configured
  fluent-bit.max_buffered_lines that value will be used instead of the general
  config.
• Added the kind field to the MAR POST body. This is a field that is used by
  Memfault to differentiate the source of a MAR entry.
• Added logs.extra_attributes option to configure extra log attributes to keep
  in the log file (similar to
  fluent-bit.extra_attributes
  which still works but will be deprecated)

Changed

• The LogCollector has gone through a refactor to make the concurrency methods
  more consistent with the rest of the code base. This has also allowed us to
  make the following change.
• Moved recovery of logs in the logs directory into the LogCollector thread.
  This prevents a case where memfaultd could be slow to start when there is a
  large number of MAR entries on disk, and depending on systemd configuration,
  could be considered crashed and restarted before booting completely.

Fixed

• When passing a null to disable a feature there was a case where the config
  merging logic would fail. This would result in a case where a subset of
  configs were not possible. Fixed this logic to allow these valid use cases.
