Regarding Updating Major Espree Version -

[rohitpraks]

Hi, We are using rcs-core in our project which inturn uses espree. The version being used in the latest rcs-core npm is espree@6.2.1 But we need espree@7.3.1 or higher to support optional chaining. Can you please help update it? Is there any reason why espree hasn't been updated recently to the latest major version in rcs-core ? Thanks!

Hey @rohitpraks thanks for your issue. There was no specific reason for it. But I will soon update it to v7+

Hi @JPeer264, we are updating the minimal supported version of Safari to >= 13.1, so the optional chaining operator is stopped being compiled by @babel/preset-env as expected (other browsers support it for a while now). And that throws during the rcs-core renaming. That is the reason we need to update espree.

Now the latest ECMA version is used in v3.7.0. I also removed the package lock to ensure you get always the latest minor/patch versions (which is IMO better for libraries like this one)

Thanks a lot. Will try to incorporate it and see how it goes
