- Update to version 1.4.3:
  * Minor bug fixes and documentation improvements have been made to
  the following functions:
    fir2       remez       residuez
    sos2tf     sos2zp      xcorr
    zp2sos

- Update to version 1.4.2:
  * The compiled functions have been made compatible with recent
    changes in the development version of Octave.
  * Minor bug fixes and documentation improvements have been made
    to the following functions: cplxreal, cheb2ap, buffer,
    data2fun, ss2zp, clustersegmen ncauer, cohere, csd, pburg,
    pwelch, pyulear, tfe, invfreq, invfreqs, invfreqz, upfirdn.
  * The following new functions have been added to the signal
    package: sos2ss.

- Fix build with current octave versions:
  Substitute gripes.h -> errwarn.h, functions gripe_* -> err_*
  Substitute NINT -> octave::math::nint

- Update to version 1.4.0:
  * The buttord, cheb1ord, cheb2ord, and ellipord functions now
    support analog filter design with the "s" option.
  * The cheb1ord and cheb2ord functions will now compute the
    filter order for band-stop or notch filters.
  * The medfilt1 function has been completely rewritten to support
    additional arguments and options and to improve Matlab
    compatibility.
  * The following new functions have been added to the signal
    package: cconv, pow2db, udecode, db2pow, rms, uencode,
    peak2peak, rssq, unshiftdata, peak2rms, shiftdata.
  * Other functions that have been changed for smaller bugfixes,
    increased Matlab compatibility, or performance: bitrevorder,
    ellip, primitive, buffer, findpeaks, rectpuls, butter,
    fracshift, schtrig, cheby1, gauspuls, sigmoid_train, cheby2,
    gausswin, specgram, chirp, impz, square, cplxreal, invfreqs,
    tripuls, data2fun, invfreqz, digitrevorder, marcumq.

- Update to version 1.3.2
  * The package is no longer dependent on the general package.

Update to version 1.3.1
  * The following window functions now accept a Matlab compatible option
    to select the periodic variant, useful for FFT applications:
    blackmanharris    hann
    blackmannuttall   nuttallwin
  * The following filter design functions have improved and more
    consistent input parameter validation:
    buttord    cheb2ord
    cheb1ord   ellipord

- Split from octave-forge package, version 1.3.0
