	This release is devoted to a fix for Bug 219838 reported by Frank.
    2.74
	    ERRATA
	        Bug 219838  the psx go package fails to build standalone.
	            You can work around this by go mod vendor in your code tree
	             or upgrade your package reference to psx/v1.2.75.
	    This release addresses Bug 219687 reported by David Runge.
	        Code at HEAD (tagged {cap,psx}/v1.2.74-rc5) fixes it for
		 {x86,arm,mips}x{32-bit,64-bit}, ppc64, s390x and riscv.
	            The mips32 support requires a more modern Go compiler than the
		     default provided by Debian. For successfully testing I used
		     go1.24.0.
	            May be fixed for loongarch, but no system to test this with
		     (derived from mips, so perhaps it is fixed).
	    Group syntax parsing bugfix for pam_cap from Tianjia Zhang.
	    Doc typo fix for cap_get_proc.3 from Tianjia Zhang.
	    Fix transitive include in capsh.c from Leo.
	    Go package documentation updates, including more cap examples.
