1.20.0

This release adds support for log filtering as well as a few bug fixes. Check
out the logging docs for more
information on log filtering!

Added

• Added support for log message filtering. This feature gives you the ability to
  exclude log lines that are spammy or contain potentially sensitive information
  from being uploaded to Memfault.
• Added built-in logs-to-metric rules that increment counter metrics when a
  systemd_restarts or oomkill event is detected. These are widely applicable
  to most Linux distros, and represent a good base for metric collection

Fixed

• Fixed a problem where large HRT files could take a long time to write. This
  was due to the file writer not being buffered.
• Fixed a race condition that caused the journald cursor to not be written.
  This would lead to the journald log collector capturing duplicate log lines
  if memfaultd is restarted.
• Fixed a problem where daily heartbeats were being saved when they were not
  enabled.

Removed

• Combined the regex feature with the logging feature to simplify feature
  management as log filtering and matching based on regexes becomes a key part
  of our logging offering.
