<p>Hi all,</p>
<p>I enjoy reading the discussion on this tricky topic. Thank you
for looking into this!<br>
</p>
<p>What would be the precise plan of action?</p>
<p>The situation is, a new QGIS 3.4.13 release based on gdal3/proj6
is out already. We cannot make that undone unless we get out the
message to forget that 3.4.13 ever existed and ask everyone to
reinstall 3.4.12.</p>
<p>I wonder if it wouldn't be easier to setup a system somewhere to
build with the old gdal and proj libraries to create the remaining
standalone installers to push out the remaining three 3.4 releases
(manually). With LTR we have built a brand with a very good
reputation and I think we should protect this label and avoid any
controversial communication if reasonably possible.<br>
</p>
<p>It's possible that I am underestimating the work which would be
required to do this, but in my opinion this would be a good
opportunity to do an ad-hoc investment into Jürgen (given that he
has some of his precious time left to actually work on this and
that he does not completely disagree with me).<br>
</p>
<p>Best regards</p>
<p>Matthias<br>

Yes, actually QGIS 3.4 should not be affected by
the PROJ fix, because it <br>
uses the old pj_transform() API with doesn't
trigger that code path at all. <br>
But it *is* affected by exportToProj4() no longer
returning +datum or +towgs84 <br>
in cases where it used to be, which basically
makes working with anything != <br>
WGS 84 fundamentaly broken. The only "fix" would
be to backport the fully <br>
fledged PROJ 6 support of 3.10 which is obviously
unreasonable to do in 3.4<br>
