46c131e5676e NEWS: Save old NEWS in NEWS.3. New NEWS file for 4.0 release. Rik <rik@octave.org> parents: 12733 diff changeset	7 because it is not quite as polished as we would like, we have
46c131e5676e NEWS: Save old NEWS in NEWS.3. New NEWS file for 4.0 release. Rik <rik@octave.org> parents: 12733 diff changeset	8 decided to wait until the 4.0.x release series before making the

46c131e5676e NEWS: Save old NEWS in NEWS.3. New NEWS file for 4.0 release. Rik <rik@octave.org> parents: 12733 diff changeset	12 Given the length of time and the number of bug fixes and
46c131e5676e NEWS: Save old NEWS in NEWS.3. New NEWS file for 4.0 release. Rik <rik@octave.org> parents: 12733 diff changeset	13 improvements since the last major release Octave, we also decided
46c131e5676e NEWS: Save old NEWS in NEWS.3. New NEWS file for 4.0 release. Rik <rik@octave.org> parents: 12733 diff changeset	14 against delaying the release of all these new improvements any
