Please use .. versionadded:: 5.2.0 instead. Place it below the section header. That's consistent with the rest of the docs.

Perhaps just say that it is the conversion factor to meters? Otherwise I would say that "SI unit" is closer to standard nomenclature. Also valid below.

"conversion factor to meters"... if it is linear unit, otherwise it is to radian. I can add that precision
src/PJ_unitconvert.c

Good idea to add this function. Makes the code a bit easier to read. Small style nitpick: The rest of the functions use snake case so it looks a bit odd that this is named in camel case.
Non-sense, but should we try to protect against this ? |

I didn't think it would be necessary to protect against creation of non-sense pipelines but of course there were complaints that you could do just that. This is somewhat similar so maybe it is better to just take care of that in advance. It is not a top priority for me - it can also be handled by explaining the behaviour in the docs. |

If you put it right below the heading it is more clear that it is the whole section that was added in version 5.2.0

ok, I've added a consistency check for the unit types in xy_in vs xy_out and z_in vs z_out |

You should add a string representation in src/pj_strerrno.c as well

Good point. I've added a comment at the end of the enumeration to update pj_strerrno.c AND pj_transform.c as well (and I've sanitized the access to the transient_error array in it)

Add the string representation of the new error code and I am happy with this. It's a nice new feature to have! |
…and document that it supports numeric factors (refs OSGeo#1053)
