Misago

Upgrade Misago to a release containing PR #2224, which adds context managers so FieldFile instances are closed after reading. The fixed pattern is:

with model.file_field.open():
    file_content = model.file_field.read()

Do not call model.file_field.read() without the context manager, as that can leave the file pointer open and cause file-locking errors on Windows and unnecessary resource noise on Linux.

Use Misago's class-extension API. Decorate a plugin mixin with @extend(TargetViewClass), then override the view method and call super() to retain the original behavior:

@extend(CategoryThreadListView)
class PluginCategoryThreadListViewMixin:
    def get_context_data(self, **kwargs):
        context_data = super().get_context_data(**kwargs)
        context_data["top_components"].append(
            {"template_name": "plugin/component.html"}
        )
        return context_data

This lets a plugin modify an entire extensible view instead of implementing many separate filter hooks. Ensure the overridden method accepts the same arguments as the original view method.
