[macOS] OpenSSL 1.1 will be removed and OpenSSL 3 will be the default for all macOS images from November 4

[sarathrajsrinivasan]

Breaking changes

OpenSSL 1.1 will be removed from all macOS images and the default version will be switched to OpenSSL 3.

Target date

Image deployment will start on November 4 and will take 2-3 days.

The motivation for the changes

OpenSSL 1.1 has reached its end-of-life (EOL) and is no longer supported. Due to its deprecation, Homebrew has removed it from its available packages.

Possible impact

If your library/project is not compatible with OpenSSL 3 and you build them based on default OpenSSL version - your workflow will be broken.
