Release checklist

Initialize release

• Create release issue. Already a step complete! 😉
• Create release branch

Update version number

• Define update version number as described here.
• Update the version number in all Cargo.toml files (i.e. all workspace crates).
  • Specifically, for the pre-1.0 versions the versioning strategy is currently as follows:
    • The minor version number is the same for all workspace crates, and incremented
      for each release.
    • The patch version is increased on a as-needed basis, separately per crate.
• The Clap App version number in src/main.rs will be equal to the version number in the root Cargo.toml.

Update the dependency licenses to be included in the binary as per their licenses

• Run cargo run --example update_dep_licenses to update the licenses of dependencies, which will be included in a binary build.

Create Release PR

• Create release PR

Verify

• Verify formatting with cargo +nightly fmt.
• Does cargo test succeed?
• Verify image output of images produced with cargo test --features output-test-images.
• Do all CI runs complete successfully?
• Are the versions indeed updated for all packages?
• Is the application version updated?
• Are the dependency licenses updated?

Completed!
