Besides that, I cant compile due to missing deps.
Does someone already have info on what debian packages i need to
install?

14fac78 solved both the proj download related crash and the ~100 m
positional error for lat-long and NZTM fixed points. I have attached
a cut down version of the therion.log file that was produced.
I am a little confused, as Therion automatically downloaded the grid
and yet my therion.ini does not have any of the proj-auto or
proj-missing-grid settings mentioned in the 14fac78 Therion Book pg
86-87, which raises for me many questions. I assume the functionality
of those ini statements is now superseded by the proj.ini that is now
present in the install folders (as you described as "use the best
transformation and download the grids if needed") and that the Therion
Book is yet to be updated?
Or maybe I am not looking I the correct place for the ini files that
Therion is actually using?
Can Therion be run without having internet access (or without first
having had internet access for a particular survey dataset at some
previous time)?
In the attached file, do the transformations marked [no] and [yes]
relate to whether they are used or not?
And presumably the accuracies listed are the estimated accuracies?
Can I use proj-missing-grid to improve the accuracy of my example
further or is 4m accuracy the best I am likely to get for this
particular dataset?
Regards
Bruce

Something bad happened between 6.0.0 and 6.0.5 that we only just
noticed today (because for day to day work we only compile small
sections of the cave).
Therion 6.05 has moved some of our fixed stations about 100 m north
(those specified with cs lat-long and cs EPSG:2193 NZTM) and others
(specified with cs EPSG:27200 NZMG) stayed in their correct locations,
severely distorting our cave. No errors reported, just outputs with
large loop errors and distorted cave.
Interestingly, it is the old archaic format NZMG that performs
correctly and the modern and lat-long are relocated.
The image below is located with NZMG, as is the cave entrance in the
centre. The cave entrances left and right are located with either
lat-long or NZTM.
Before reporting this I thought I'd better at least try 6.0.6+3bc6556
I get a crash right away as the therion.log transcript below
indicates.

Should I be using one of the new cs-trans or proj-* commands or is
there something else?

Hi all,
Therion has been supporting the advanced features of the Proj library
for some time now. (Proj's purpose is to do transformations between
coordinate systems.) This functionality was disabled by default and
you could enable it using 'proj-auto' and 'proj-missing-grid' options
in the initialization file.
'proj-auto' lets Proj choose the best transformation and you can set
'proj-missing-grid' to download a grid file (see
https://proj.org/usage/transformation.html#grid-based-datum-adjustments)
if the transformation needs it; see the therion book for details. The
log file lists all the transformations chosen and used at the end.
The latest commit (3bc6556) enables this "use the best transformation
and download the grids if needed" functionality. We know that
automatic downloads are a sensitive issue, but in this case we can
trust the Proj library not to do any harm
( https://proj.org/usage/network.html ) and the user experience is
much better.
Could you check if this version works well with your data sets? The
windows installer is available here:
https://github.com/therion/therion/actions/runs/2203811478 (use the
msys2 version which uses up-to-date Proj library; you need to be
logged in to github to download it).
M.
