In general I'm ready to approve the PR but I wonder whether you've considered the current situation with 5.0.0-rc release - the "rc" part means it's release candidate only, so there will come 5.0.0 release at some point. In theory, 5.0.0 release can be backwards incompatible with the *-rc release and here we're already releasing the new version.

What do you think?

[h4nsu]

Yes, I'm aware it's maybe a bit premature. But I tested these changes also on version use-ink/ink#2063 which most likely will end up as ink! 5.0.0. Also, this repo here has versioned releases to crates, I think nothing particularly bad will happen if the main branch contains some "work-in-progress" for some time.

So just by bumping the version in Cargo.toml here, it won't publish automatically to crates.io?

[h4nsu]

Nope, publishing on crates.io is a manual process triggered locally via cargo, not from GH

Personally I prefer when it's done automatically, when it detects a new version of Cargo.toml but that's for another discussion.

Looks cool, I've been playing around with it and everything seems to work, nicely done!
