UPX has been updated to version 4.2.3, see the release news for changes:
https://upx.github.io/upx-news.txt UPX is a free, portable, extendable, high-performance executable packer for several executable formats. UPX upstream bundles all dependencies as source and links them in directly during the build starting with this release, so the Cygwin package no longer depends on zlib0 and ucl. -- -- *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** The easiest way to unsubscribe is to visit <https://cygwin.com/mailman/options/cygwin-announce>, and click 'Unsubscribe'.
