-Needs Python 3.10 or newer (on 3.9, pip stops with `ResolutionImpossible`); `pip install` works too, and the other install paths are in [Getting started](https://geiserx.github.io/Wayback-Archive/getting-started/). That run takes about a minute, ends with a `Download Complete!` block counting the files downloaded, failed and skipped, and opens from disk as the page above: the homepage, its stylesheet and its images are all within the first 50 files. Drop `MAX_FILES` to fetch the whole site. On another site a short run can stop before a stylesheet that is only reached through `@import`, because the crawl fetches files in the order it finds them. There are no flags: every setting is an environment variable, listed in [Configuration](https://geiserx.github.io/Wayback-Archive/configuration/).
+Use 1.5.0 or later: in 1.4.6 and earlier an archived page can make the tool fetch any host directly and save the response ([#55](https://github.com/GeiserX/Wayback-Archive/pull/55)), and `pipx upgrade wayback-archive` moves an existing install (one made with Python 3.9 needs `pipx reinstall --python python3.10 wayback-archive` instead).

-Wayback-Archive needs Python 3.10 or newer. On Python 3.9, pip skips 1.5.0, tries 1.4.2 to 1.4.6, finds that the `requests` version they need does not install on 3.9, and stops with `ERROR: ResolutionImpossible`. The `python3` that ships with macOS is 3.9. Install Python 3.10 or newer (for example `brew install python`) and install again with pipx or in a new virtual environment.
+Wayback-Archive needs Python 3.10 or newer. On Python 3.9, pip skips 1.5.0 and finds no older release it can use: it stops with `ERROR: ResolutionImpossible` while it can still try 1.4.2 to 1.4.6 (their `requests` does not install on 3.9), and with `ERROR: No matching distribution found for wayback-archive` once those are yanked. The `python3` that ships with macOS is 3.9. Install Python 3.10 or newer (for example `brew install python`) and install again with pipx or in a new virtual environment.
