[ANN] dtas 0.20.0 - duct tape audio suite for *nix

[Eric Wong]

Free Software command-line tools for audio playback, mastering, and
whatever else related to audio.  dtas follows the worse-is-better
philosophy and acts as duct tape to combine existing command-line tools
for flexibility and ease-of-development.  dtas is currently implemented
in Ruby, Perl5, and some embedded shell, but may use other languages in
the future.

Changes:

    dtas 0.20.0 - ruby 3.1+ compatibility, splitfx improvements

    This release catches up with Psych (YAML) changes in Ruby 3.1+
    Ruby 2.3+ is now the minimum version, though keep in mind the
    ruby-core team already dropped support for it long ago.

    Most of the features are focused on audio engineering
    capabilities of dtas-splitfx.  dtas-splitfx gains the --filter
    switch, along with per-track environment variables and comments.
    These new features have made my workflow significantly better.

    dtas-archive supports explicit comments, and omits the default
    SoX comment.  To better cope with temporary and modified files
    during editing, dtas-player metadata now checks ctime before
    reusing the cache, handy for frequently-modified files.
    "dtas-tl prune" is now supported to cull temporary files from
    the player tracklist.

    There's a few dtas-console improvements, too.

    28 changes since v0.19.0 (2021-09-05):

          archive: support comments, default to none
