 # MacDirStat 0.7.0
 
-Draft for Pavol. Not published. To release: check the app on a Mac, then
-`git tag v0.7.0 && git push origin v0.7.0` (the version in `Cargo.toml` is already 0.7.0).
-The release workflow writes GitHub's generated notes, not this file; once it has run, replace
-them with everything below the line: `gh release edit v0.7.0 --notes-file <this file minus
-this preamble>`. Put the date in CHANGELOG.md's 0.7.0 heading at the same time.

 This release changes how MacDirStat looks and what it asks you to decide. It is still free, still
 reads your disk only on your Mac, and still deletes nothing until you confirm.
