The failures appear to come from Python 3.14 incompatibilities in dependencies:
These prevent all of Iris' CI running correctly. However the vast majority of tests have run, and have passed, including many tests which exercise I believe we are therefore able to provide Python 3.14 compatibility, although we're not yet able to provide support due to these CI problems preventing full coverage. |

@pp-mo - the following changes were made to get the CI working without
Possible alternative to the above (w.r.t. doctests):Bill and I have been chatting about the possibility of dynamically updating the docstring ( I've run out of time to explore this further now, but if you think it sounds doable, then I'll have a play next week. |

Also, something else to consider is that we only run doctest for the newest python version, so the doctests for geovista are not being run at all at the momnet. Should we consider adding in a |

A temporary switch to only Python 3.13 for doctests would be my favoured approach, so long as we've captured it in an issue for future. |

@pp-mo - Any thoughts on this? If I switch the doctests to run on py3.13, rather than py3.14, then the changes made to keep the doctests running (in da2617f) are technically not necessary and more. Although it might be good to keep them to future proof this kind of issue with pyvista taking some time to catch up with newer python releases? |

There was a problem hiding this comment.
Thanks @ukmo-ccbunney. Its cool that this solves the problem now and also if it would come up again in the future.

Description
Scientific Python - SPEC 0 β Minimum Supported Dependencies
Closes #6775
Slight hiccup:
3.14.1patch release. See π¦ Iris 3.14.xΒ #6626 (comment)So here are my proposed steps:
v3.14.xrelease branch, which will give the3.14.1release compatibility with Python 3.14.v3.14.xtomain; this needn't wait for the release itself.main.pyvistais 3.14 compatible. (see Reinstategeovistain py314 lockfile whenpyvistais py314 compatible.Β #6902)The above pattern will avoid Git conflicts and maintain maximum integrity in our Git history, avoiding situations where a change has two different SHAs depending on which branch it is on.
