How does one upgrade to the latest release?

[normatovjj]

Once a llamafile has been downloaded, say Llama3 8B, in order to run it on MacOS a simple command line is all that's needed. But then with the latest release v0.8.x that improves a number of issues, how do I update and use the latest llamafile version?

Say I got Llama3 8B with llamafile 0.8.1 but there is 0.8.4 available. I see that there is an updated version of the model WITH 0.8.4 llamafile but that just means every time a new update comes out, the whole model should be re-downloaded.
