v4.0.0-rc1

New Features

• Actually removal of features:
  • No longer an escript
  • Functionality that is a duplicate of rebar3 has been removed
  • rebar3 is now able to pass a map of OTP Applications so relx does not need to do a discovery step
  • Releases are no longer discovered unless needed
• Add support for exref, {exref, [Apps]} and src_tests
  • Neither form of exref will work if using rebar3 as an escript. Install with rebar3 local install in order to use this feature.
• Add support for multiple mode types:
  • dev: Same as the old dev_mode option. Creates symlinks for applications and configuration.
  • minimal: Same as prod but does not include ERTS in the release.
  • prod: Strips debug info from beam modules, includes ERTS and excludes src
• Extended start script no longer requires exact version of ERTS but attempts to use the one in the PATH if none is bundled in release
• On OTP-23:
  • extended start script will use erl_call instead of nodetool
  • remote shell will not bind to a listen port making use of epmdless simpler

New Defaults

• extended_start_script is true by
• Automatically includes config/sys.config[.src] and config/vm.args[.src]
  • set {sys_config, false} and {vm_args, false} to force them to be left out
• Release boot script is now always named start.boot

Bug Fixes

• {include_src, false} properly leaves out src and include of all applications, including OTP system applications
• copy dir in overlay bug
• remove doc and man dir from erts when copying to release
• fix fallback version number that is currently a tuple {plain, "0"}
• boot script name is different after tarring
• how to call an rpc with multiple arguments?
• git describe failure

Backwards Incompatible Changes

Start Script

• eval requires trailing period: bin/<release_script> eval "3."
• rpcterms removed
• rpc takes list of arguments, so to call foo:bar(1,2,3): bin/<release_script> foo bar "[1,2,3]."
• start renamed to daemon
  • attach renamed to daemon_attach
• remote_console has aliases remote and remsh

Release building

• Provider support removed from relx
• No support for goal restrictions like {appname, "> 1.1.1"}
