- Update to version 5.2.0
  This release contains mostly feature requests.
  Features:
  * The stats1 verb now lets you use regular expressions to
    specify which field names to compute statistics on, and/or which
    to group by. Full details are here.
  * The min and max DSL functions, and the min/max/percentile
    aggregators for the stats1 and merge-fields verbs, now support
    numeric as well as string field values. (For mixed string/numeric
    fields, numbers compare before strings.) This means in particular
    that order statistics -- min, max, and non-interpolated
    percentiles -- as well as mode, antimode, and count are now
    possible on string-only fields. (Of course, any operations
    requiring arithmetic on values, such as computing sums, averages,
    or interpolated percentiles, yield an error on string-valued
    input.)
  * There is a new DSL function mapexcept which returns a copy of
    the argument with specified key(s), if any, unset. The motivating
    use-case is to split records to multiple filenames depending on
    particular field value, which is omitted from the output: mlr
    --from f.dat put 'tee > "/tmp/data-".$a, mapexcept($*, "a")'
    Likewise, mapselect returns a copy of the argument with only
    specified key(s), if any, set. This resolves #137.
  * A new -u option for count-distinct allows unlashed counts for
    multiple field names. For example, with -f a,b and without -u,
    count-distinct computes counts for distinct pairs of a and b field
    values. With -f a,b and with -u, it computes counts for distinct a
    field values and counts for distinct b field values separately.
  * If you build from source, you can now do ./configure without
    first doing autoreconf -fiv. This resolves #131.
  * The UTF-8 BOM sequence 0xef 0xbb 0xbf is now automatically
    ignored from the start of CSV files. (The same is already done for
    JSON files.) This resolves #138.
  * For put and filter with -S, program literals such as the 6 in
    $x = 6 were being parsed as strings. This is not sensible, since
    the -S option for put and filter is intended to suppress numeric
    conversion of record data, not program literals. To get string 6
    one may use $x = "6".
  Documentation:
  * A new cookbook example shows how to compute differences
    between successive queries, e.g. to find out what changed in
    time-varying data when you run and rerun a SQL query.
  * Another new cookbook example shows how to compute
    interquartile ranges.
  * A third new cookbook example shows how to compute weighted
    means.
  Bugfixes:
  * CRLF line-endings were not being correctly autodetected when
    I/O formats were specified using --c2j et al.
  * Integer division by zero was causing a fatal runtime
    exception, rather than computing inf or nan as in the
    floating-point case.

- Update to 5.1.0 (see changelog at 
  https://github.com/johnkerl/miller/releases/tag/v5.1.0)

-------------------------------------------------------------------
Sun Mar 12 21:04:27 UTC 2017 - aloisio@gmx.com

- Update to version 5.0.1
  Minor bugfixes:
  * As described in #132, mlr nest was incorrectly splitting
    fields with multi-character separators.
  * The XTAB-format reader, when using multi-character IPS,
    was incorrectly splitting key-value pairs, but only when
    reading from standard input (e.g. on a pipe or less-than
    redirect).
