Hi Mathieu,
Thanks a lot. It reads very well!
Something that I'd like to add is that in case of still finding a bug,
users should file issues and to mention proximity of LTR replacement.
If you still happen to find QGIS behaving in an unexpected way, please
let us know on https://github.com/qgis/QGIS/issues
<https://www.google.com/url?q=https://github.com/qgis/QGIS/issues&sa=D&source=hangouts&ust=1579773605204000&usg=AFQjCNHP21SO7MPYwrn023vHOeZwMUBKuQ>
as always. We are very happy that QGIS 3.10 is now in shape to replace
3.4 as LTR in a month time.
Bests

Paolo, here's the draft blog post:
*Public Service Announcement: Update to the latest point release now*
------
QGIS users who have adopted the 3.10 version when initially released
at the end of October 2019 have likely noticed a sharp drop in
reliability. The underlying issues have now been addressed in 3.10.2,
all users are advised to update *now*.
When QGIS 3.10 was first released in the end of October 2019, a pair
of libraries – namely GDAL and PROJ – were updated to their
next-generation versions. The advantages are plenty: GeoPDF export[1]
support, more accurate coordinate transformation, etc. For those
interested, more technical information on this is available here[2].
The update of these crucial libraries led to a number of regressions.
While we expected some issues to arise, the seriousness of the
disruption caught us off guard. Yet, it was also somewhat inevitable:
QGIS is the first large GIS project to expose these next-generation
libraries to the masses. The large number of QGIS users across the
globe were essentially stress testing both new code within QGIS as
well as the libraries themselves.
Thanks to dedicated users taking time to file in report and the
community helping out as well as our project sponsors for allowing us
to fund development time, developers have been able to fix all known
regressions in both in QGIS as well as underlying GDAL and PROJ
libraries, benefiting a large number of open source projects.
As a result of this collective effort by the community, QGIS 3.10.2 is
now back to being the reliable and stable GIS software we all love. As
such, we cannot stress enough the important of updating now.
Once again, thanks to our community of testers, sponsors, and
developers for their countless hours and efforts in making QGIS better.
Happy mapping!

Fully agreed. Mathieu, would you like to write it?
Thanks.

+100 on all that's been said here.
Also, once 3.10.2 is updated to include the updated packages &
above-referred fix, I'd suggest writing a QGIS.org blog post
to inform users of the worthiness of updating to 3.10.2(.2)
*ASAP*, and expand a bit on why 3.10.0/.1 were such rough
releases. We can finish the post by thanking users that have
reported bugs (an inevitable nightmare to go through as QGIS
was exposing brand new GDAL3/PROJ6 versions to the masses).
IMHO, we should not skip this communication to our users.

Gosh, will the nightmare ever end... Let's agree never to
change
anything in gdal or proj or qgis ever again ;)

Subject: Urgent: Remove windows 3.10.2 installer from site
To: qgis-developer <[email protected]
<mailto:[email protected]>>
Can we please remove the 3.10.2 installer from the website
as a matter
of urgency? This installer was released using the older
gdal 3.0.2 and
proj 6.2 versions, which directly lead to crashes and
reprojection
failures in QGIS.
QGIS ********************SHOULD NEVER
EVER*********************** be
used with gdal >= 3 and gdal < 3.0.3 or proj >6 and proj <
6.3.0.
This combination is a world of hurt for users :(
Tickets filed at
https://trac.osgeo.org/osgeo4w/ticket/618, and
https://trac.osgeo.org/osgeo4w/ticket/617, and later today
I'm going
to commit cmake blocks which will completely prevent
compilation under
the affected gdal/proj versions.
