Neither the ja3n nor the ja3 fingerprints match. So, it would not be possible to use safari17_0 impersonate with safari version 18_0 and above on a mac.

As for iOS, I see that safari is on v17_6_1 and it still matches the fingerprint of safari17_2_ios. Fingerprint might change for v18_0 for iOS. Will keep you posted.

Is a new impersonate in the works for safari? How should we handle this?

Could please elaborate on your platform details, my Safari does not share the same fingerprints with yours.

Curl-Cffi: v0.7.3

MacOS:

Chip: Apple M1 Pro
macOS: macOS Sonoma (v14.7.1)

Safari on Mac: Version 18.1 (19619.2.8.111.5, 19619)

The latest curl-cffi library version available is 0.7.3, but in the documentation, I do see support for safari18_0 and safati18_0_ios. But, this is on v0.8.0. Is this even available for use?
