    Vote on existing issues, or file a new one if one doesn't already exist. We do pay attention to a few of the nudges in these threads, but really discourage people from turning the entire thread into a discussion point for a single feature.

    Heads up, lots of people are just coming back from vacation, so we'll be releasing the beta next week instead.

    Heya Daniel Rosenwasser (@DanielRosenwasser), I've started to create the release-4.2 branch for you. Here's the link to my best guess at the log.

    Looks like the "origin types" PR (#42149) has broken the baselines, which is making tests fail.

    FYI - it looks like NPM has a version 4.2.4, but GitHub doesn't have a tag v4.2.4 or a release for 4.2.4.

    Can we expect to have a v4.2.4 defined by 2021-04-12, or is more time needed before that can happen?
    Within Google we're anxious to get the fix for JSDoc annotations getting copied to overloads.
    It's causing spurious deprecation warnings for our users.
    We need an official v4.2.4 tag so we can upgrade.
    Thanks.
