v8.4.0

Features

• Support multiple --exec <cmd> instances, see #406 and #960 (@tmccombs)

Bugfixes

• "Argument list too long" errors can not appear anymore when using --exec-batch/-X, as the command invocations are automatically batched at the maximum possible size, even if --batch-size is not given. See #410 and #1020 (@tavianator)

Changes

• Directories are now printed with an additional path separator at the end: foo/bar/, see #436 and #812 (@yyogo)
• The -u flag was changed to be equivalent to -HI (previously, a single -u was only equivalent to -I). Additional -u flags are still allowed, but ignored. See #840 and #986 (@jacksontheel)

Other

• Added installation instructions for RHEL8, see #989 (@ethsol)
