+The tool is quite feature-complete, but some important features like (the
+equivalent of) `git blame` and `git log <paths>` are not yet supported. There
+are also several performance bugs. It's also likely that workflows and setups
+different from what I personally use are not well supported. For example,
+pull-request workflows currently require too many manual steps.
+
+I have almost exclusively used `jj` to develop the project itself since early
+January 2021. I haven't had to re-clone from source (I don't think I've even had
+to restore from backup).
+
+There *will* be changes to workflows and backward-incompatible changes to the
+on-disk formats before version 1.0.0. Even the binary's name may change (i.e.
+away from `jj`). For any format changes, I'll try to implement transparent
+upgrades (as I've done with recent changes), or provide upgrade commands or
+scripts if requested.
