Code snippet discussing the use of the `cargo info` command to check package publication status:

/// Check if the package is published via `cargo info`.
///
/// `cargo info` shouldn't be used by a machine because its output is not a stable API.
/// However, checking if a package is published by using other methods is annoying, so
/// we accept that release-plz might not work with future cargo versions and we will fix
/// it when that happens.
///
/// Returns whether the package is published.

$Rust code snippet showing nested functions using anyhow::Result and with_context chaining, printing an error stack with "hello", "world", and "!!!!" causes. Code: use anyhow::Context; fn main() { let res = hello2().unwrap_err(); println!("{res:?}") } fn hello2() -> anyhow::Result<()> { hello1().with_context(|| "hello") } fn hello1() -> anyhow::Result<()> { hello0().with_context(|| "world") } fn hello0() -> anyhow::Result<()> { anyhow::bail!("!!!!") } Shell output: $ cargo -q run hello Caused by: 0: world 1: !!!!$

Workflow of release-plz that deleted the crates-io-auth-action. You don't need to pass the cargo_registry_token anymore, too. For more info, see the release-plz docs!

Content: "Just want to give a big thank you! I realized that my CI runs on release-plz for well over two years and never failed once. In fact, it's so reliable that every single release was a non-event. This project is a bit like git. Yes you can work without it, but you would be very stupid to even try... Keep up the good work and recognize, your work keeps countless projects running.💪"

add permissions id-token: write, and use the github action to generate the crates-io token, as explained in crates.io docs.
