Conflicting information for minimum Chrome version 64 or 80

Subject

Guides > Launching Browsers > Chrome Browsers

Description

In the section Guides > Launching Browsers > Chrome Browsers it states:

All Chrome* flavored browsers will be detected and are supported above Chrome 64.

This contradicts the information in Guides > Launching Browsers > Browser versions supported in a previous section on the same page which says:

Cypress supports the browser versions below:

Chrome 80 and above.

The documentation is therefore inconsistent and should be changed to state the same minimum Chrome version in all places - either 64 or 80.

In terms of how Cypress is actually operating:

https://github.com/cypress-io/cypress/blob/0f9a150647146c3e63e14d298d7fcf7ad5c92b66/packages/launcher/lib/known-browsers.ts#L3-L10 shows:

// Chrome started exposing CDP 1.3 in 64
export const MIN_CHROME_VERSION = 64

// Firefox started exposing CDP in 86
export const MIN_FIREFOX_VERSION = 86

// Edge switched to Blink in 79
export const MIN_EDGE_VERSION = 79

so it appears that a minimum version of Chrome 64 is enforced in Cypress 13.x, not a minimum version of 80.

@jennifer-shehane same on this one. Can you confirm the update?

[jennifer-shehane]

I feel like there is a restriction that doesn't allow it to function after Chrome 80 that was introduced in v10. I can't remember exactly what it was nor can I find it. I'm fine with 80 though.

Our previous strategy was to put the minimum version that Cypress will work - like we KNOW it breaks and doesn't function before that.

If we want our strategy to be moreso - 'we will not support issues from these older browsers and work with you on it', then we could put a later Chrome version. Honestly the instances of issues I've seen on really old browsers feels pretty small, or nonexistent though....so I'm not sure this is an active problem.

• It's true that there is very little activity on older browsers, however the recent issue Is there a Cypress version that supports Chrome 66 browser？ #5887 highlighted the confusion.

• I suggest to deprecate Chrome < 80 in the changelogs of the next release e.g. 13.14.0 and add that information consistently to the documentation.

@MikeMcC399 Yes, this sounds fine to me

[MikeMcC399]

• docs: updating supported browser versions #5104 (comment) provides an explanation about the different levels of support for Chrome 64 and Chrome >= 80

Yes! There it is!
