BREAKING CHANGE: This deprecates the IS-(MAC|WINDOWS|LINUX|BSD) family of global constants in favor of a native `featurep` check: IS-MAC -> (featurep :system 'macos) IS-WINDOWS -> (featurep :system 'windows) IS-LINUX -> (featurep :system 'linux) IS-BSD -> (featurep :system 'bsd) The constants will stick around until the v3 release so folks can still use it -- and there are still some modules that use it, but I'll phase those uses out gradually. Fix: #7479
