A while ago I updated InvokeAI to 2.3.1 and during the update it told me that pip had a new version [notice] A new release of pip available: 22.3.1 -> 23.0.1 and to update it using python -m pip install --upgrade pip, which I did later that day.
Today I finally updated to 2.3.3, but it spit out the same message about updating pip. It hasn't registered that I've updated pip. I ran the update option from the invoke.bat file (option 9) multiple times to verify that it isn't a fluke, and even attempted to update pip again, only to be told that it is already 23.0.1. Every time I ran the update option, it has continued to insist that the version of pip I have is 22.3.1, and asks me to update it to 23.0.1.
It is only a minor issue and, as far as I am aware, it has not impacted my ability to use InvokeAI.
