The fourth release candidate of Octave 3.8.1 is available now from
alpha.gnu.org in the directory /gnu/octave:

   cecbbd9bed2182246e3961ae30b89ccf  octave-3.8.1-rc4.tar.gz  (md5sum)

   -rw-r--r-- 1 3003 3002 20688476 Feb 26 20:26 octave-3.8.1-rc4.tar.gz

Please help make the 3.8.1 release a success by building from this release
candidate and reporting any problems.

Unless there are significant problems, this will become 3.8.2 within a week
or so.

3.8.1-rc4 will soon be the default build for mxe-octave.

  PASS     11476
  FAIL         4

Fails are the importdata.m tests:

If I change importdata.m importdata_ascii line 182
From: delim = regexp (row, '[+-\d.eE\*ij ]+([^+-\d.ij])[+-\d.ij]',
          'tokens', 'once');
To: delim = regexp (row, '[\+\-\d.eE\*ij ]+([^\+\-\d.ij])[\+\-\d.ij]',
          'tokens', 'once');

It then passes
