Features

• Added support for themes and included a few as well: default, eldar,
  monocai, night-owl, solarized-light, and solarized-dark. The theme
  can be changed using the ':config' command, like so:
  :config /ui/theme night-owl
  Consult the online documentation for defining a new theme at:
  https://lnav.readthedocs.io/en/latest/config.html#theme-definitions
• Added support for custom keymaps and included the following: de, fr,
  uk, us. The keymap can be changed using the ':config' command, like so:
  :config /ui/keymap uk
  Consult the online documentation for defining a new keymap at:
  https://lnav.readthedocs.io/en/latest/config.html#keymap-definitions
• The following JSON-Schemas have been published for the log format and
  configuration JSON files:
  https://lnav.org/schemas/format-v1.schema.json
  https://lnav.org/schemas/config-v1.schema.json
  Formats should be updated to reference the schema using the "$schema"
  property.
• Indexing of new data in log files can now be paused by pressing '='
  and unpaused by pressing it again. The bottom status bar will display
  'Paused' in the right corner while paused.
• CMake is now a supported way to build.
• When viewing data from the standard-input, a symbolic name can be used
  to preserve session state. The name can be changed using the
  "rename-stdin" lnav script or by doing an UPDATE to the filepath
  column of the lnav_file table. For example, to assign the name
  "journald", the following SQL statement can be executed in lnav:
  ;UPDATE lnav_file SET filepath='journald' WHERE filepath='stdin'
• The size of the terminal can be accessed in SQL using the $LINES and
  $COLS variables.
• The raise_error(msg) SQL function has been added to make it easier to
  raise an error in an lnav script to stop execution and notify the user.
• Added the json_concat() function to make it easier to append/concatenate
  values onto arrays.
• Added the ":write-jsonlines-to" command that writes the result of a SQL
  query to a file in the JSON Lines format.

Interface Changes

• Data piped into lnav is no longer dumped to the console after exit.
  Instead a file containing the data is left in .lnav/stdin-captures/
  and a message is printed to the console indicating the file name.
• In time-offset mode, the deltas for messages before the first mark
  are now negative instead of relative to the start of the log.
• The $XDG_CONFIG_HOME environment variable (or ~/.config directory) are
  now respected for storing lnav's configuration. If you have an existing
  ~/.lnav directory, that will continue to be used until you move it to
  $XDG_CONFIG_HOME/lnav or ~/.config/lnav.
• Removed the ':save-config' command. Changes to the configuration are now
  immediately saved.

Fixes

• Added 'notice' log level.
• If a "timestamp-format" is used in an element of a "line-format", the
  field name is ignored and a formatted timestamp is always used.
• Ignore stdin when it is connected to /dev/null.
