[Unreleased]

The new jj print command prints the contents of a file in a revision.
jj move and jj squash now lets you limit the set of changes to move by specifying paths on the command line (in addition to the --interactive mode). For example, use jj move --to @-- foo to move the changes to file (or directory) foo in the working copy to the grandparent commit.
The $JJ_CONFIG environment variable can now point to a directory. If it does, all files in the directory will be read, in alphabetical order.
You can now override the $EDITOR environment variable by setting the ui.editor config. There is also a new $JJ_EDITOR environment variable, which has even higher priority than the config.

Errors are now printed to stderr (they used to be printed to stdout).
jj untrack now requires at least one path (allowing no arguments was a UX bug).
You now get a proper error message instead of a crash when $EDITOR doesn't exist or exits with an error.

Dropped support for config in ~/.jjconfig. Your configuration is now read from <config dir>/jj/config.toml, where <config dir> is ${XDG_CONFIG_HOME} or ~/.config/ on Linux, ~/Library/Application Support/ on macOS, and ~\AppData\Roaming\ on Windows.

You can now set an environment variable called $JJ_CONFIG to a path to a config file. That will then be read instead of your regular config file. This is mostly intended for testing and scripts.
The standard $NO_COLOR environment variable is now respected.
jj new now lets you specify a description with --message/-m.
When you check out a commit, the old commit no longer automatically gets abandoned if it's empty and has descendants, it only gets abandoned if it's empty and does not have descendants.
(#111) When undoing an earlier operation, any new commits on top of commits from the undone operation will be rebased away. For example, let's say you rebase commit A so it becomes a new commit A', and then you create commit B on top of A'. If you now undo the rebase operation, commit B will be rebased to be on top of A instead. The same logic is used if the repo was modified by concurrent operations (so if one operation added B on top of A, and one operation rebased A as A', then B would be automatically rebased on top of A'). See #111 for more examples.
jj log now accepts -p/--patch option.

Fixed crash on jj init --git-repo=. (it almost always crashed).
When sharing the working copy with a Git repo, the automatic importing and exporting (sometimes?) didn't happen on Windows.

No changes, only trying to get the automated build to work.

(#131) Fixed crash when core.excludesFile pointed to non-existent file, and made leading ~/ in that config expand to $HOME/
