lnav v0.10.1

Features:

• Added ":show-only-this-file" command that hides all files except the
  one for the top line in the view.
• The ":write-raw-to" command now accepts a --view flag that specifies
  the source view for the data to write. For example, to write the
  results of a SQL query, you would pass "--view=db" to the command.
• The commands used to access the clipboard are now configured through
  the "tuning" section of the configuration.
• Added an "lnav_version()" SQL function that returns the current
  version string.
• Added basic support for the logfmt file format. Currently, only files
  whose lines are entirely logfmt-encoded are supported. The lines
  must also contain either a field named "time" or "ts" that contains
  the timestamp.
• Added the "logfmt2json()" SQL function to convert a string containing
  a logfmt-encoded message into a JSON object that can be operated on
  more easily.
• Added the "gzip()" and "gunzip()" SQL functions to compress values
  into a blob and decompress a blob into a string.
  Interface changes:
• The xclip implementation for accessing the system clipboard now writes
  to the "clipboard" selection instead of the "primary" selection.
• The 'query' bookmark type and y/Y hotkeys have been removed due to
  performance issues and the functionality is probably rarely used.

Bug Fixes:

• The text "send-input" would show up on some terminals instead of
  ignoring the escape sequence. This control sequence was only
  intended to be used in the test suite.
• Remote file synchronization has been optimized a bit.
• Configuration values loaded from the ~/.lnav/configs directory
  are now included in the default configuration, so they won't be
  saved into the ~/.lnav/config.json user configuration file.
• Key handling in the visual filter editor will no longer swallow
  certain key-presses when editing a filter.
• Scrolling performance restored in the SQL view.
• The ':redirect-to' command now works with '/dev/clipboard'
• The field overlay (opened by pressing 'p') now shows 'log_time'
  for the timestamp field instead of the name defined in the format.
• The search term in the bottom status bar will now update properly
  when switching views.
• The "Out-Of-Time-Order Message" overlay will be shown again.
• The tab for the "Files" panel will be highlighted in red if there
  is an issue opening a file.
• Overwritten files should be reloaded again.
• The "jget()" SQL function now returns numbers with the correct type.
• The "json_contains()" SQL function now returns false if the first
  argument is NULL instead of NULL.
• The local copies of remote files are now cleaned up after a couple
  days of the host not being accessed.
• The initial loading and indexing phase has been optimized.
