CHANGES IN R 4.2.1 patched NEW FEATURES

• (macOS) The run-time check for libraries from XQuartz for X11 and Tcl/Tk no longer uses ‘otool’ from the Apple Developer Tools (PR#18400).

• On Windows, environment variable ‘R_LIBCURL_SSL_REVOKE_BEST_EFFORT’ can be used to switch to only ‘best-effort’ SSL certificate revocation checks with the default ‘"libcurl"’ download method. This reduces security, but may be needed for downloads to work with MITM proxies (PR#18379).
