@CaerusKaru , could we also include those 3 PRs?

1. fix(duplicate): fix #1081, load patch should also check the duplicate flag #1121
2. fix(event): fix #1110, nodejs EventEmitter should support Symbol eventName #1113
3. fix(core): fix interval will still run after cancelled error #1156

Thanks!

Any ETA for this release?

[CaerusKaru]

@mhevery I've rebased this PR and updated the CHANGELOG. Once CI passes, it should be good to go.

[CaerusKaru]

@JiaLiPassion Can you help diagnose the CI failures?

[JiaLiPassion]

@CaerusKaru, sure, in fact, everything is fine, saucelabs just unstable again... I have restarted the CI.

[JiaLiPassion]

@CaerusKaru, @mhevery, CI is happy now, let's cut a new release, thanks a lot!

[MattiJarvinen]

You released unmerged version?!?

[JiaLiPassion]

@MattiJarvinen-BA, this PR will be merged tomorrow, and the version on npm is the same with this PR's commit.

Just got me confused, because I came here to read the changelog.
