Djblets 5 is based on Django 4.2 LTS, which has an End Of Life date of

April 1, 2026, and will be the last scheduled LTS release until

mid-2025.
There are a handful of issues that needed to be fixed in order to

support Django 4.2, but they're all pretty minor. Some of these could

even be backported to earlier releases.
The following changes are made:


The _clone_q() utility method no longer worked. It's been updated

   to do a deepcopy, which is now supported by Q() objects.


The Conditions field widget tests had to be updated for changes to

   form field HTML.


App and model management in TestModelsLoaderMixin had to have some

   tweaks to avoid making some assumptions and to ensure population of

   new installed apps.


mark_safe_lazy() had the wrong type mapped for results. This didn't

   impact anything seriously before, but Django is now more sensitive to

   it.  This could be backported, but won't be just to ensure there are

   no unforeseen regressions.


pytz.utc generated warnings in a unit test. We now use Django's

utc.


Some tests_app values were old and incorrect. They didn't break

   anything before, but Django's more strict now about mappings. These

   have been removed in order to use the correct default module for the

   models.


There are other fixes that will be coming for datetime/timezone imports

and staticfiles storage API. These currently generate warnings, but

otherwise work as before. We'll fix them to future-proof early in order

to ease testing with Django 5 down the road.

Installed in a new virtualenv and tested against all supported versions

of Python. All tests pass.
