Bump version to 0.30.0

[bradfier]

Version bump, primarily to get #832 and #892 in now that 1.19 is out and untagged unions are usable in stable!

r? @emilio

Thanks for the pull request, and welcome! The Servo team is excited to review your changes, and you should hear from @emilio (or someone else) soon.

From the test output, the stable rust side is still emitting BindgenUnion(https://github.com/rust-lang-nursery/rust-bindgen/blob/master/tests/expectations/tests/anon_struct_in_union_1_0.rs)

[emilio]

Those are testing Rust 1.0 output.

Anyway, doing a new release sounds fine to me, @fitzgen, any reason we shouldn't?

[fitzgen]

Did stylo folks end up making their own bug-fix-only branch yet?

I see no reason not to release a 0.30.0 crate.

• Didn't, but no reason we can't in the future if we need to. shrug

@emilio I'll write release notes and publish to crates.io if you haven't already

[emilio]

I planned to do so when it merges, but feel free to :)

[fitzgen]

Both release notes and publishing, or just the latter?

[emilio]

Mostly publishing. If you could do relnotes that'd be awesome, because it's taking a bit and I'm about to head out.

[fitzgen]

Sure thing
