Suggested change

	- pyqt {{pyqt}} # [(linux64 or win) and python_impl == "cpython"]
	- pyqt >=5 # [(linux64 or win) and python_impl == "cpython"]

Prefer >=5 notation in the run section over {{pyqt}} (it's designed for the host section).

Do we need pyqt {{pyqt}} in the host to pin it 6.11? See https://github.com/AnacondaRecipes/aggregate/blob/master/conda_build_config.yaml#L891C6-L891C10

[maciejtraczyk]

this change was change was suggested by linter check but you're right it suppose to apply only to the host section I had to missed that.

"matplotlib-feedstock/recipe/meta.yaml:/outputs/1/requirements/host/1: host_section_needs_exact_pinnings: pyqt in host should be pinned to its conda_build_config.yaml value: pyqt {{ pyqt }}."

when it comes to bumping pyqt into 6.11 I think we can stay with >= 5 as there Is no sign of it as a requirement so to avoid further solver conflicts In my opinion we can stay with >=5, unless I missing something @skupr-anaconda?

[cbouss]

The linter flags pinning in host so that a specific version is used (i.e. the one set in the cbc).
The runtime constraint itself is set by the run_exports of the package (https://github.com/AnacondaRecipes/pyqt-feedstock/blob/master/recipe/meta.yaml#L65).

So

host:
- pyqt {{ pyqt }}
run:
- pyqt >=5

Will render as:

host:
- pyqt 6.11
run:
- pyqt >=5
- pyqt >=6.11.0,<6.12.0

We shouldn't pin in run to pyqt {{ pyqt }}
