I upgraded from my distribution provided pre-1.0 version of pijul to a cargo install of v1.0.0-alpha.48 recently.

Today, when attempting to get the latest pijul sources (so that I can use the [new identity/author stuffs](https://pijul.org/posts/2021-06-28-two-changes/)), I got the following error:

```auto
jakimfett@system:~/run/pijul$ RUST_LOG="pijul=debug,libpijul::apply=debug,libpijul::output=debug" pijul clone https://nest.pijul.com/pijul/pijul

(...snip long seemingly irrelevant bits...)

Subsequent attempts seem to fail at different places in the download/patch process…

```auto

```

…but they all fail with that final statement of “Version mismatch”.  
Any ideas what could cause this behavior?

I saw the [clone issues](https://discourse.pijul.org/t/what-to-do-with-a-changestore-error-on-clone/674/10) and [interpreting errors](https://discourse.pijul.org/t/any-ideas-for-interpreting-error-messages/742) as relevant but neither gave me a path forward in fixing the issue myself.

Have attempted to find the ‘beta’ channel in `cargo`, but either it’s not a thing (yet?) or my cargo-fu is weak, quite possibly the latter.

Hi! I can’t reproduce, unfortunately. It seems to always choke on `XF3FR…`, which seems to be the oldest patch in the history of Pijul with the new format. Maybe upgrading to the latest Pijul from [crates.io](http://crates.io) could fix it?  
`cargo install --version "~1.0.0-alpha" pijul`
