- update to 1.8:
** Changes in Behavior
Schedule -f/--full combined with non-linewise operations for deprecation.
In a future release, -f/--full will only be usable with operations where
it makes sense. For now, we print a warning to stderr when -f/--full is
used with non-linewise operations, and such usage will no longer be
supported.
* The bin operation now uses more intuitive bins. Previously, a command
such as `datamash bin 1 <<< -0` would output -100; and -100 did not fall
in its own bin. We now require all bins to take the form `[nx,(n+1)x)`
with integer n and bin width x. We discard the sign on -0 and gate such
inputs into the [0,x) bin.
* Operations taking more than one argument now provide more complete output
with --header-out. Previously, an operation such as `pcov x:y` would
produce an output header like `pcov(y)`, discarding the `x`. The new
behavior will output header `pcov(x,y)`.
* datamash(1) no longer ignores --output-delimiter with the rmdup operation.
** New Features
* New datamash option --sort-cmd argument to specify the program used
by the -s option to sort input, plus enhancements to the security and
portability of building sort command lines.
* New datamash option -c/--collapse-delimiter=X argument uses character
X instead of comma between values in collapse and unique lists.
* New datamash operations: mean square (ms) and root mean square (rms).
* Decorate now supports sorting IP addresses of both versions 4 and 6
together. IPv4 addresses are logically converted to IPv6 addresses,
either as IPv4-Mapped (ipv6v4map) or IPv4-Compatible (ipv6v4comp)
addresses.
* Add two command aliases:
'echo' may now be used instead of 'cut'.
